[android-developers] need help in proving ownership of app and website

[patney2016]

dear all, i recently purchased a dating template from 
https://www.chameleonsocial.com/buy.php and have named the website 
www.see2date.com. The domain being registered from godaddy.

The supplier has also given the android package along with website which i 
uploaded to play store. the app has been suspended because i have not been 
able to prove ownership of the website.spoke to the chameleon guys and 
go daddy but both have given their apprehension of giving any legal 
documents...

would request help on how to convince play store abt authenticity of of my 
website.if i am not mistaken, i should link the website to the android 
app and vice versa through the creation of Digital Asset Links files.

would request information on whether this would be sufficient to restore my 
app on google play and reverse my lost credibility in play store

thank you all

[android-developers] Need help on Android 6.0 on : how to enable the ip forward functionalityvia adb on Android 6.0

[Yang Sean]

In a recent project , I have enabled 2 network cards on the Android 6.0(1 
for internal networks and 2 for external internet, the client can ping its 
own gateway by now )---now I want to enable the ip forward for these 2 
networks so that intranet client also can access internet via network 2, 
but it seems it can't work if I input the following cmd via adb:
  
echo 1 > /proc/sys/net/ipv4/ip_forward

Is there anyway to prove ip_forward dose work as expected ?

Re: [android-developers] Need help on sending events (Motion event, Key event and etc) from a service to system (android 4.0)

[jim mcdonald]

Hi, I have a similar question. We are developing an app for Android TV and 
using a couple different HID devices. One has axis and buttons and works 
great. The other has only axis and no buttons - and shows up as an HID 
device with the driver, but not as an input device, so we can't get events. 
Any thoughts on how to fix this? Do we need some kind of manifest or 
intent-filter to recognize the device?
Thanks!

Hello all.

While im following every youtube tutorial how to set up android studio i

Everyone who installed Android Studio instantly see's the built in ui 
designer. (when they started a new project)

Now the problem is, i dont see this designer. And i cannot figure out why 
im not seeing it. is it becuase of the HAXM acceleration which im not able 
to do with my laptop?

[android-developers] Need help adapting BluetoothLEGatt example by adding 1 new view

[quique123]

Im trying to modify an existing project, the BluetoothLeGatt example, to 
turn it into ArduDroid, which is this app used to interface with Arduino 
via BT.  The ArduDroid looks like this:



I have already figured out how to design this far.  The original app 
consisted of:

DeviceScanActivity.java as the main activity which only had an optionsMenu 
with 2 buttons (scan and stop)

DeviceControlActivity.java

BluetoothLeService.java

SampleGattAttributes.java

These came with the following xml layout files:

listitem_device.xml

actionbar_indeterminate_progress.xml

gatt_services_characteristics.xml

I added these 2:

ArduDroidActivity.java

activity_main.xml

So far ArduDroidActivity.java only calls 
setContentView(R.layout.activity_main).  I am calling it from a button in 
the DeviceScanActivity, by adding a sendMessage() method which creates an 
Intent and starts the new activity.  The problem so far is that I cant see 
the button.

I wasnt sure how to add the button, I figured I could just throw it into 
the listitem_device.xml so I added these lines:

http://schemas.android.com/apk/res/android;
  android:orientation="vertical"
  android:layout_width="match_parent"
  android:layout_height="wrap_content">







But when I run the app I cant see the button.

Any ideas why?

Im hoping I can call my new activity_main.xml so that I can access all the 
buttons and sliders in order to send commands to a bluetooth module on an 
arduino.

[Jigar Patel]

Hey Android Developers, 

I am new to developing android apps. I have downloaded the Android Studio 
software but I don't know how to use it. I want to make an app where I tap 
the screen and it plays a video in full screen. Then when I tap anywhere in 
the screen again I want to be able to skip to another part of the video. 
How can I make this app? I would really appreciate the help. Its a win-win 
situation if you help me you learn something and I will learn something too.

Thanks

Re: [android-developers] Need help in every way!

[Xyler Aston]

I figured the RAM might not be sufficient which is crazy that it needs that 
much RAM but I do IT and am working on finding a PC to get about 6 to 8 GB 
of RAM or seeing if I have enough lying around to update this one. 

For the second I don't have a clue where to find the crash logs. When I 
looked it up it there appear to be 10 different places the crash log might 
be. I can give you the code though. All I did was take the Hello World text 
and change it to login and put two small text boxes, delete the text and 
put a hint on each one for username and password. I'm completely new to 
Android Studio. In Microsoft Visual Studio all I have to do is double click 
on the designer to get to the code page. How do I get the code in Android 
Studio because that doesn't seem to work and I'm not sure where the code 
file is stored? I did attach a screenshot of what the app looks like and 
the only attribute I changed was the hint as shown in the image attached.

authorized. However, every time I try to run it it says the app has crashed 
before it even loads. I am using a Samsung Galaxy s3 so I tried it with API 
17. So here are my questions.

#1:
Why is this program s slow? I have changed the gradle to be 
offline. I have also added this line to the 
properties org.gradle.daemon=true and still it takes forever and almost 
freezes up my computer.

#2:
Why aren't my labels showing when I run it through the emulator? I mean 
that's about as simple as you can get and it isn't even working.

#3:
Why does my phone crash before even loading the app? I have 32 GB of memory

#4:
Can this program really be as bad as it seems? I've been "working with it" 
about 3 days now and I can't get it to function properly in any way.

Re: [android-developers] Need help in every way!

[Tushar Lal]

Hi Xyler Aston,

The answer for your first question is that 4GB RAM is just not enough. I
know that on
http://developer.android.com/sdk/index.html?gclid=CMzG7fSkxcsCFdIRaAodWoIFtg#Requirements
it says that 4GB is enough because that depends upon how much RAM & CUP are
being taken up by other process & application.

As for the third question either you have to share the crash logs or your
code.

And for your forth and final question we can only say after seeing the
code. But by the description that you provided it can't be that bad.



Regards:
Tushar Lal

Re: [android-developers] NEED HELP!!! How can I get history from Android browser in Android M without READ_HISTORY_BOOKMARKS permission?

Seems like they don't want you to do that anymore

If your app targets Android 6.0 (API level 23) or higher, don't access

[android-developers] Need help with Tracked channels (UTM) in google play console

[mohan krishna]

Need help with Tracked channels (UTM) in google play console (user 
acquisition) please.
I want to track which source is giving me more installs in developer 
console user acquisition section.
I used this link 
https://developers.google.com/analytics/devguides/collection/android/v4/campaigns#google-play-url-builder
 
to create urls for different sources and placed them in different sources 
from where i get users. But i don't see any measurement in my user 
acquisition-> performance page in google developer console, even after more 
than one week, i can see other numbers like "Play Store (organic)" for same 
date but "Tracked channels (UTM)" is still zero even after one week.
Thank you in advance for the help.

[android-developers] Need Help - Android Wear IME Question

[Katja DeCuir]

hey. making an IME for android wear. i've got a few questions before i go 
about doing this.

1. i have a keyboard IME already designed and written.. for Android. (i was 
told to go ahead and write a normal android IME before using it on android 
wear)

2. so, i have this IME and zero idea of where to go next to get it on the 
android wear. do i just install to my phone and go into development mode 
and enable the IME on the watch? do i add lines of code somewhere to make 
it specifically for the android wear?

3. i know for a fact you can use IMEs on the android wear. there's things 
everywhere about how to install minuum or whatever and enable input methods 
on the watch.. my question, are the keyboards for android wear all 
full-blown SMS apps that just have a keyboard in them as part of the app? 
do i need to write an SMS app? or will my keyboard just pop up when i hit 
reply to a text message popup on the watch? (such as the normal popup from 
the standard android messaging app that comes with the phone.. as 
currently, hitting reply opens it on the phone, whereas reply with voice 
lets you talk to it.) or will it bring up another option to reply with an 
IME?

any help is useful. thanks so much. i know those are probably stupid 
beginner questions, but i must be overlooking some shred of information 
somewhere because i'm unable to answer this myself. any relevant links or 
info would be extremely useful. if any more info is needed, just ask.

Re: [android-developers] Need help setting table column width

[Salil]

Thanks TreKing

One more observation is - first column always takes some specific width. I 
tried by putting a blank string in the fist column and build. Then the 
first column still takes some specific width and rest of the columns are 
taking it's required width.

I tried different ways - but couldn't figure out a logical reason for this 
behavior. 

thanks
Salil

 I don't see anything blatantly wrong with your Java file. So I would

Please show the full chunk of code you're using to create your table.


 This is my first project in Android and hence my knowledge about the
 internals of UI elements are not that good. Hence I am not sure where to
 hit for solving the problem. That is why I am dependent on the community.
 Sorry if the question asked is a silly one.


That's fine, your question is not silly, I'm just trying to get you to
share the relevant pieces of information that will help me or someone else

You need to clearly show what you have done and what results you have

it. Based on that result being positive, it would show an alertdialog to 
tell the user there is an update available for some files (that are parts 
of my app).

Problem is : I'd like to start that loader on app launch, and deliver the 
alertdialog anywhere in the app, whatever activity the user is in.

I searched for a solution. Thought about putting the loader work in the 
Application class, but really not sure it's a viable solution.

TL;DR : Do you have any idea how to do background process on app launch, 
that would delivers an alertdialog independently of the activity user's in?

[android-developers] Need help with AVD

[Asaf Nassi]

When I create a new device in AVD I need to fill detail,
I understand what is the Definition in the left side:  name, screen 
size, resolution, sensors, cameras, input and RAM,
but I don't understand what is the Definition in the right side: size, 
screen ratio, density, buttons and device states.
what that mean?

Thanks Asaf

Re: [android-developers] Re: [Android-developers]:need help in creating bluetooth file transfer app. urgent

[bob]

Change this:

InputStream instream = socket.getInputStream();

to this:

*OutputStream outstream = socket.getOutputStream();*


Change this:

instream.read( buffer);

to this:

*outstream.write( buffer);*

[android-developers] need help showing a download link to my app.

[J.Willison]

Published my first app last night (15 hours ago)
I believe my app package is called com.wSLBridalApp
I cannot seem to figure out how to find it on google play.
I uploaded it, added screenshots etc, and published it.

Can't search for it (which I'm told takes a while to populate) but i should 
be able to link to it using the app package id right?

I don't know how to figure out how to link to it...

Sorry I'm new here and have never done this.

thanks in advance for the help.

[android-developers] Need help with dx too many methods error

[Bala]

Hi,

I recently started testing out scala on android by coding an android project 
(https://github.com/prashanthbala/scaladroid) using the android plugin for 
Scala (https://github.com/jberkel/android-plugin/wiki/getting-started)  
The compilation and create of .dex files using android:package-debug was taking 
about 2-3 minutes, which was pushing down my development speed a lot.  

So I tried to use, ProguardCache (https://github.com/banshee/ProguardCache) on 
sbt to reduce the build time. However, I am getting errors running the final 
android-package debug (after compile and proguard-cache-build) on sbt 

trouble writing output: Too many methods: 193353; max is 65536 .. dx: 
Nonzero exit value: 2 

due to the 16-bit limit on the number of method names for davlik.

My hunch is that either the proguard step is not treeshaking the libraries used 
completely or the final package-debug is not using the pruned versions of the 
libraries. 
The project still builds fine without proguardCache.

Wondering if my proguard settings in ./proguard.conf are wrong or if my 
Build.scala settings are conflicting with the process. 

I've spend quite some time trying to fix this, any help would be appreciated. 
The files are available at https://github.com/prashanthbala/scaladroid.

Thanks

[android-developers] Need help on sending events (Motion event, Key event and etc) from a service to system (android 4.0)

[Prabudas]

Hi,

I am working on an external HID device for android 4.0 devices. The device 
will have a touchpad and hardware buttons to replicate the touch screen and 
android buttons(Home, back and menu). To make this device work with any 
android 4.0 device, I do not want to modify the build or root the device. 
All I can do is, I can write an app (service) which can interact with this 
device through USB (using accessory mode v 1.0). So, from that app, I want 
to create the necessary events based on the message from USB. This can be 
very easy in android 4.1 with accessory mode 2.0. But, I need this for 4.0. 
Please help me on this. Thanks in advance.

Re: [android-developers] Need help on sending events (Motion event, Key event and etc) from a service to system (android 4.0)

[Dianne Hackborn]

Currently the only way, outside of test environments, to deliver input
events to the platform is throw a kernel input device.  So your USB device
must report itself as a HID device (a keyboard, trackpad, mouse, or game
controller) which the kernel understands how to interact with and will
generate the appropriate low-level events from the input device.

Dianne, thanks for your reply. Can I have a touch screen as an external HID 
(without add / modify any driver) in the same way like mouse and keyboard? 
Thanks.

[android-developers] NEED HELP!! - Food Menu Order/List Application

[Steve Meier]

I hope someone can help.  

I have an application that I am building that currently has 3 main Layouts. 
All String-Arrays are in XML.  First Screen Shows, Breakfast, Lunch  
Dinner.  Now depending on which Button is selected, Example Lunch a 2nd 
Layout comes up Showing the Lunch Menu items, such as Cheeseburger, 
Hamburger, Hot Dog, French Fries, Onion Rings...  Let's say I select 
Cheeseburger, the Item is Added to the 3rd Layout.  When I click the Back 
button on the phone and select a new item such as Onion Rings that item 
replaces the Cheeseburger.  I need it to ADD it to the List, not replace 
it.  Can someone please tell me where my code is wrong?  

Summary,  I need the list to get appended with the items selected, not 
replaced by the selected item.


Here is my lunchActivity.java

[CODE]
package com.mycompany.foodmenu;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;
 
public class lunchActivity extends Activity {

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.lunchmain);
final ListView lv=(ListView)findViewById(R.id.listView1);   
   
ArrayAdapterCharSequence 
adapter=ArrayAdapter.createFromResource(this, 
R.array.lunch_menu,android.R.layout.simple_list_item_1);
lv.setAdapter(adapter);
lv.setOnItemClickListener(new OnItemClickListener() {

@Override
public void onItemClick(AdapterView? arg0, View arg1, int arg2, long 
arg3) {
   // TODO Auto-generated method stub 
String item=lv.getItemAtPosition(arg2).toString();
   String itemordered;
   itemordered = item +  added to list;
   Toast.makeText(getApplicationContext(), itemordered, 
Toast.LENGTH_LONG).show();
   
// Launching new Activity on selecting List Item
Intent i = new Intent(getApplicationContext(), ListItem.class);
// sending data to new activity
i.putExtra(item, item);
startActivity(i); 
}
});
}
}
[/CODE]

Here is the lunch.xml menu file that read by the lunchActivity to create 
the first ListView

[CODE]
resources

string-array name=lunch_menu
itemCheeseburger/item
itemHamburger/item
itemBacon Cheeseburger/item
itemHot Dog/item
itemFrench Fries/item
itemOnion Rings/item
/string-array

/resources
[/CODE]

Here is the listItem.java

[CODE]
package com.mycompany.foodmenu;

import java.util.ArrayList;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class listItem extends Activity{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.selecteditems);

Intent i = getIntent();

ArrayListString myNewList = new ArrayListString();
String item = i.getStringExtra(item);

myNewList.add(item);
ListView selecteditems = (ListView) findViewById(R.id.listitems);

ArrayAdapterString adapter = new ArrayAdapterString(ListItem.this, 
android.R.layout.simple_list_item_1, myNewList);
selecteditems.setAdapter(adapter);
// adapter.notifyDataSetChanged(); 


}
}
[/CODE]

BTW.  I have tried changing [CODE]myNewList.add(item);[/CODE]  to 
[CODE]myNewList.addAll(item);[/CODE] and it just creates new problems.  I 
have also tried adding [CODE]adapter.notifyDataSetChanged();[/CODE] to the 
end and it makes no difference.

And here is the selectedItems.xml file that is suppose to get populated 
with the Selected Items from the Lunch Menu

[CODE]
?xml version=1.0 encoding=utf-8?
LinearLayout
  xmlns:android=http://schemas.android.com/apk/res/android;
  android:orientation=vertical
  android:background=@drawable/main_background 
  android:paddingLeft=10.0dip 
  android:paddingTop=0.0dip 
  android:paddingRight=10.0dip 
  android:paddingBottom=10.0dip 
  android:layout_width=fill_parent 
  android:layout_height=fill_parent

  ListView 
  android:id=@+id/listitems
  android:layout_width=fill_parent
  android:layout_height=wrap_content
  android:textSize=25dip
  android:textStyle=bold
  android:padding=10dip
  android:textColor=#ff/

/LinearLayout
[/CODE]

Any help would be greatly appreciated!!

[android-developers] Need help - hidden GPS monitoring app

[Mihai Popescu]

Hello,

I am rather new to Android, and I need some information and opinions.

I intend to develop an application which would run on some Android phone, 
seeminglessly in the background, and send periodic messages to a server, 
regarding its current position (GPS coordinates).

The most important aspect here would be that:
- the application is intented to be preinstalled on a bunch of phones, 
before they will be used by a specific group of people.
- the user must not be able to stop/kill the application without some kind 
of password
- the user must not be able tu turn off his GPRS/3G internet connection.

I am aware that there are some security restrictions for developing such an 
app, but still my question is wether or not it would be possible to do it.

I assume that if not, the next best thing would be to customize the Android 
OS with these changes, and deploy it on the set of phones :D

1-Write a web service that accepts lat and long parameters. The details of
this are off-topic for this list.
2-Write code in your app to send the lat and long values to your web
service that now expects it.

[android-developers] Need help for thread cancelable queue pattern.

[Tolriq]

Hello,

I need some help to find the correct way to implement my need.

The need as i see it is simple : Implement a queued synchronization thread 
model where queue elements can be removed / canceled.
The second problem is that i use lots of interface so I don't really know 
the numbers of different item in queue and what the sync process do.

The need from users perspective : Interface with different screens like for 
example movie / music / tv show /  each with a refresh button that 
allow refresh of data (can take some time) and an cancel button if it's 
taking too long and the user change his mind.

What I do now is : A service that adds sync details to a queued list and 
start the working thread if it's not. This works ok but does not support 
canceling.

The problem now is how to handle cancellation, should i start new thread 
for the sync in the queue thread and associated it with current action 
someway, should i cancel the main thread and restart it (but what about 
cancellation that can takes times if sync is locked in sockets so going ANR 
...).

I suppose there's a pattern to handle that but I can't find it :(

And a little supplemental question that is linked to this, the sync process 
can be for example a function that call 3 functions that each takes a lot's 
of time, in each functions I can check for thread.interrupted to stop it, 
but from documentation it clears the flag so the main function won't know 
and will continue to other calls so again what's the correct way to handle 
the interrupt propagation ?

Thanks for your help,
Tolriq.

Re: [android-developers] need help working with very large (photo) bitmaps

[Massycat]

 Perhaps there's some method of processing the photo and filter bitmaps in
 chunks in a way I'm not aware of?  Something that doesn't eventually end
 up right back at an eventual out of memory error?  Or some other method?

 Have a look at 
BitmapRegionDecoderhttp://developer.android.com/reference/android/graphics/BitmapRegionDecoder.html
 which 
should allow you to load a region of an image, process it and save the 
result without loading the entire image into memory.
It is available in API level 10 and above.

Ouch.  Oh well, I doubt many Froyo phones have more than a 3 MP camera,
anyways.  Of course, they also probably (based on my phone) have a lot
less memory, too.  :-(

Thanks, either way---it WILL be useful.

Re: [android-developers] need help working with very large (photo) bitmaps

[Streets Of Boston]

Note that createScaledBitmap may return the same bitmap as the input... 
when the input parameters *width *and *height *are the same as the 
width/height of your input bitmap:

Change the code as follows (bold part is the changed part):

Bitmap bmp1 = Bitmap.createScaledBitmap(src, width, height, false); 
*if (bmp1 != src) {*
   src.recycle(); src = null;
*}*

Do a similar thing for bmp2 and dst.

I'm a photographer as well (not professional, though)  :)

Using RGB_565 is ok for most purposes. The camera quality of most phones 
are not up to snuff yet to really warrant a 8-bit color space. However, 
camera quality of some devices is starting to catch up. But for now, people 
taking pics with their phones would need no better than RGB_565 processing.

  We don't have enough of your code. But suppose you have this code 
 executed:

 Ok, here's the actual code for the exact part that WAS causing the problem:

public Bitmap mergeBitmaps(Bitmap src, Bitmap dest, int width, int 
 height) {

   Bitmap bmp1 = Bitmap.createScaledBitmap(src, width, height, false);
   src.recycle() ; src = null;

   Bitmap bmp2 = Bitmap.createScaledBitmap(dest, width, height, false);
   dest.recycle() ; dest = null;

 And then bmp1 and bmp2 were used from that point on.  Note that this code
 has now been deleted.  I use src and dest directly.  I was originally
 doing resizing at the end here, but that went away, and this code was
 removed (well, the bmp1 and bmp2 parts, and the two recycle()s).

 After that, the question was more just to learn why it didn't work as I
 thought it would.  Now, I think I understand.  By using bmp1 and bmp2, I
 WAS still using src and dest, even though they'd been recycled ... BAM!
 FORCE CLOSE.
 
 And thank you for explaning that to me.  I always thought that creating a
 bitmap from another one was creating an entirely new bitmap, not still
 using the old one.  Now I know what not to do.  :-)

 Btw, just FYI, on an old (for this thread) topic:  out of curiosity, I
 re-read RGB_565 to find out how many thousands of colors it had, and if
 I might want to go ahead and consider it after all.  Then I read this
 (in Bitmap.Config):

   This configuration may be useful when using opaque
   bitmaps that do not require high color fidelity.

 There's no way this fits into a camera app primarily geared for serious
 photography, looking at adding diffusion filters to soften faces, fog
 filters (you can do a LOT with a low fog, moderately deep blue filter,
 and the right scene/environment), and so on.  Think of it like going to
 any of the planet's beautifyl natural wonders, with a camera.  Which
 would you rather have (and this is based on film):  a point and shoot
 35mm with the cheapest and crappiest film you could buy, or a Nikon F4
 35mm with Kodak Ektar Professional 100 ASA film?  Yeah  :-)   I
 thought of that comparison a few hours ago, and it fits, even though it's
 film, not digital[1].

 Thanks,
--jim


 [1] OT:  I still prefer film for some photography, at least, until I
 have the money to get the latest---whatever is the latest at that
 time---Nikon professional-class DSLR.  And maybe still even then,
 unless, by that time, digital has more density and color depth
 than pro-quality film like Ektar Pro, which can literally be enlarged
 to WALL sized without a hint of grainyness (pixelation for digital).
 In fact, even its old non-pro predecessor, Ektar 125, which I
 discovered around 1990 or so, could be.  I saw it first-hand, and it
 was incredible (and it was a BIG wall).  But that is WAY off-topic,
 so I'll end this bit here.

Except for one minor detail you missed:  those are examples that WERE
problems, before I changed the location where I was setting the size
of the bitmaps for the end of the app (moved that to the end), and
both bmp1 and bmp2 no longer exist.  :-)

 I'm a photographer as well (not professional, though)  :)

I'm not a pro, either, but I was taught by one while I was in 16SOW
Intelligence (he was a professional before cross-training into Intel).
I learned a lot.  :-)   I learned about Ektar, however, somewhere around
1990, with the old non-pro Ektar line, and when I found out that my old
favorite, Ektar 125, was now Ektar Pro 100, I had my favorite film back.
:-)

 Using RGB_565 is ok for most purposes. The camera quality of most phones 
 are not up to snuff yet to really warrant a 8-bit color space. However, 
 camera quality of some devices is starting to catch up.

True on both.  But don't forget tablets and the newer phones running ICS.
Better cameras are, as you say, increasing in number with newer,
higher-quality devices.

I'm not building this for the past...I'm building it with an eye toward
the future, and MY tablet (Acer Iconia A500 ... should get ICS sometime
starting around the end of next week) is only 5 MP, but it has great
color.

Besides, I KNOW I saw an old post from someone who described saving
chunks of the file to files (not jpeg, just raw data) and then, I think
it was in another process spawned by the app, processing and saving the
huge image.  I'd do the same for the image, recycle it, then create,
split, and save the chunks of the filter...then process in the other
process, keeping only the main image and one tiny chunk at a time in
memory, and finally, save it from the second process.

I don't know how to DO that yet, but I will.  Throughout this entire
app, the fact that I haven't known how to do something hasn't stopped
me yet (and I've made big progress blasting through those would-be
blockades), and it's not going to now.  (As I mentioned in another
post, I've learned many times more working on this app than all of
my other apps combined, and that pace hasn't slowed down yet, and
I don't mind that a bit.)

 But for now, people taking pics with their phones would need no better
 than RGB_565 processing.

True.  But then, I draw a definite line between taking pictures and
photography.  And, like I would imagine most photography hobbiests/pros
do, I do both.  So I'm making this app for both (but I'm keeping the
great color).  You can adjust the image size to anything your device's
camera will support (and I'm assuming that the device will have adequate
memory to process photos from that camera, given android:largeHeap=true
set in the manifest and Android 3.0+).  But if not, it'll soon be smart
enough to detect that, and re-size automatically as needed.  But it
won't happen today.  My brain is already screaming at me as it is.  Any
more time doing much of anything, it'll be an all-out Migraine, and I'll
lose several days, at a minimum (as always, cancer #1, blah blah blah).

Later,

Re: [android-developers] need help working with very large (photo) bitmaps

[Streets Of Boston]

First, ignore this sentence below from my previous answer entirely:
 Save the byte[] data from the camera into file directly (this is your 
JPG file).
(It was a left-over chunk of my initial answer)

The 'byte[] data' still takes up memory, because the caller (the Android 
SDK code that calls the onPictureTaken) still has hold of this byte-array. 
Setting data=null won't free that memory because only your code release 
reference to it, not the caller's code.

You can save the raw data of the camera's Bitmap (the bitmap returned from 
decodeByteArray) by calling Bitmap.getPixels a few times (saving the raw 
data in chunks)  or by calling Bitmap.copyPixelsToBuffer.

  Unless you can decode the byte[] data from the Camera yourself... this 
  would mean writing your own JPG decoder that would allow you to process 
  this byte[] data in smaller chunks, each chunk one at a time. 

 Admittedly, there will probably be some devices that absolutely will face
 limits when using the filters (and probably matrix stuff for brightness
 and contrast adjustments in post, too) that I'm providing in my app.  But
 I am determined to miinimize that to the best extent possible.  My intent
 is to make this a serious camera app, and that means maximizing image
 quality relative to the device's camera.

 What I'm planning to do, after figuring out exactly HOW I'll be doing the
 blending, is to work out the total memory required, and then use either
 getLargeMemoryClass() or getMemoryClass() to find out if the user has it.
 If they simply can't support it, advise them that the original file was
 saved, but the processed one will have to be resized to continue.

 I seem to recall, either yesterday (while I was sick and my mind was
 really foggy) seeing a suggestion, whether in private e-mail or old
 posts, I'm not sure, about saving the jpeg file in chunks, too, and I
 REALLY have no idea how to do that.

  Say you won't write your own decoder. :-)

 You won't write your own decoder.  :-)  (sorry, couldn't resist)


  That leaves you with 2 options:
  - Reduce the image size: Subsample
  - Reduce the image color depth: Dither.

 I'd rather limit size than color.  A smaller, but still having rich, full
 color is far more likely to be accepted than a larger, yet lower-quality
 image.  But I could use a 16-bit (plus Alpha, so somewhere between
 RGB_565 and ARGB_) for the filters.

  Subsample: Create a bitmap from the byte[] data:

 Already doing that for processing with the filters (also bitmaps).

 Side question:  why, after I'm finished with byte[] data, and I set it
 to null, does it still seem to sit there and chew up memory?  Also, on
 a related note, I have a couple of bitmaps in one method that are
 initially re-sized and should be recycled to protect the rest of that
 method (only really matters when handling the BIG bitmaps).  But...when
 I try that, it causes a force close, saying I'm trying to use a bitmap
 that has already been recycled (I'd just copied it to another, and
 was done with the original...not using it again in the current call
 to that method).  Ahy idea what's going on there?

  BitmapFactory.decodeByteArray and set
  BitmapFactory.Options.inSampleSize to value larger than 1 (prefrrably
  to a power of 2)

 Ok, this is something I'm not familiar with.  So does byte[] data
 need to hang around, then?  Or am I creating a bitmap and tossing
 byte[] data?   Sorry if I sound like I have no idea what we're talking
 about on this part, but frankly, I don't.  In the process of getting as
 far as I already am on this app, I've learned *FAR* more (so much it's
 measured on a log scale) about Android programming than in all of my
 previous apps combined...and then some...and I'm still learning, so
 please bear [is that the right spelling in this context?] with me.


  Dither: Create a bitmap from the byte[] data that has the RGB_565 
 encoding 
  and use dithering to avoid banding.

 Again, RGB_565 + Alpha, whatever that is, will work for the filters, but
 not for the photo.  I'd rather limit its size if that's the only option.

  Now you have a Bitmap from the BitmapFactory.decodeByteArray call.

  If creating the other (blending) bitmap would cause OutOfMemory issues, 
  chop up both the camera Bitmap.

 Ok.  I already have the filter bitmap in 640x480.  Is there a way to
 process the larger bitmap pixel-by-pixel, using that smaller one, scaled
 up in the math?  And, how do I blend (add) the color values for each
 pixel?  Or do I enlarge chunks of the smaller bitmap (in relative-sized
 chunks from the small one) to blend with the bigger one?

 decodeByteArray) by calling Bitmap.getPixels a few times (saving the raw 
 data in chunks)  or by calling Bitmap.copyPixelsToBuffer.

That's basically what I came up with.  This basically just flashed across
my brain this morning, and is a combination of ideas I'd been looking at.
It goes something like this:

1) if the device can handle this much, convert the original byte[]
   array to a bitmap (easy).  if not, re-size, notify the user, and
   deal with it.

2) assuming we got past #1, split the file into vertical chunks using

   Bitmap chunk1; // so each can be recycled immediately after use
   Bitmap chunk2;
   
   Bitmap chunkn;
   
   chunk1 = createBitmap(src, 0, 0, width, height/n);

   // save the chunk to a raw data file here

   chunk1.recycle(); chunk1 = null;

   and so on for all n chunks.

3) recycle the original photo image;

4) create the bitmap for the filter and repeat step 2 for it.

5) re-use the bitmap from 4 (or recycle it and make another new one)
   for the combined image, then, one at a time, recover the saved
   bitmap chunks and use paint/canvas to re-build them, and then
   immediately recycle the chunk once it's no longer needed.

6) Save the new photo

But there is one big question...why does recycling the bitmaps after
their last use still result in a force close, saying that I tried to use
them AFTER they were recycled?

Oh, and steps 5 and 6 may need to be done in a new process, if I can
figure out how to do that (or if someone here will point me to the
appropriate reference in the dev guide).

So, how does that sound?

 I did NOT say 15 MB.  And if that IS true, the developer's guide needs
 to be corrected, because I seem to recall it saying that ARGB_ IS
 24-bit color.  Personally, though, I think your jpeg size of 15 MB is
 on the high end, and the dev guide is right. 

 Again, just to make sure...I was responding to a post about JPEG sizes,
 NOT BITMAP SIZES.  And I am NOT pulling these file sizes out of my ass,
 I'm getting them directly from jpeg images in /mnt/sdcard/DCIM/camera.

  *But there is one big question...why does recycling the bitmaps after

We don't have enough of your code. But suppose you have this code executed:


Bitmap bitmap1 = new BitmapFactory.decode.();
...
...
Bitmap bitmap2 = bitmap1;
...
...
bitmap1.recycle();
...
...

bitmap2.getWidth(); // kaboom: You're using an already recycled bitmap.

In other words, you're assigning the same Bitmap instance to more than one 
variable or field and you are using one variable to recycle() the bitmap. 
If the code handling the other variables/fields doesn't know about the fact 
that recycle() already has been called, handling these other 
variables/fields may result in a force close (bitmap already recycled). You 
can call 'bitmap.isRecycled()' if  you don't keep track of it yourself.

 Ohhh, yeah, I hadn't thought about that.  Damn.  Not much I can do about
 that, then.

  You can save the raw data of the camera's Bitmap (the bitmap returned 
 from 
  decodeByteArray) by calling Bitmap.getPixels a few times (saving the raw 
  data in chunks)  or by calling Bitmap.copyPixelsToBuffer.

 That's basically what I came up with.  This basically just flashed across
 my brain this morning, and is a combination of ideas I'd been looking at.
 It goes something like this:

 1) if the device can handle this much, convert the original byte[]
array to a bitmap (easy).  if not, re-size, notify the user, and
deal with it.

 2) assuming we got past #1, split the file into vertical chunks using

Bitmap chunk1; // so each can be recycled immediately after use
Bitmap chunk2;

Bitmap chunkn;

chunk1 = createBitmap(src, 0, 0, width, height/n);

// save the chunk to a raw data file here

chunk1.recycle(); chunk1 = null;

and so on for all n chunks.

 3) recycle the original photo image;

 4) create the bitmap for the filter and repeat step 2 for it.

 5) re-use the bitmap from 4 (or recycle it and make another new one)
for the combined image, then, one at a time, recover the saved
bitmap chunks and use paint/canvas to re-build them, and then
immediately recycle the chunk once it's no longer needed.

 6) Save the new photo

 But there is one big question...why does recycling the bitmaps after
 their last use still result in a force close, saying that I tried to use
 them AFTER they were recycled?

 Oh, and steps 5 and 6 may need to be done in a new process, if I can
 figure out how to do that (or if someone here will point me to the
 appropriate reference in the dev guide).

 So, how does that sound?

 Thanks,

 We don't have enough of your code. But suppose you have this code executed:

Ok, here's the actual code for the exact part that WAS causing the problem:

   public Bitmap mergeBitmaps(Bitmap src, Bitmap dest, int width, int height) {

  Bitmap bmp1 = Bitmap.createScaledBitmap(src, width, height, false);
  src.recycle() ; src = null;

  Bitmap bmp2 = Bitmap.createScaledBitmap(dest, width, height, false);
  dest.recycle() ; dest = null;

And then bmp1 and bmp2 were used from that point on.  Note that this code
has now been deleted.  I use src and dest directly.  I was originally
doing resizing at the end here, but that went away, and this code was
removed (well, the bmp1 and bmp2 parts, and the two recycle()s).

After that, the question was more just to learn why it didn't work as I
thought it would.  Now, I think I understand.  By using bmp1 and bmp2, I
WAS still using src and dest, even though they'd been recycled ... BAM!
FORCE CLOSE.

And thank you for explaning that to me.  I always thought that creating a
bitmap from another one was creating an entirely new bitmap, not still
using the old one.  Now I know what not to do.  :-)

Btw, just FYI, on an old (for this thread) topic:  out of curiosity, I
re-read RGB_565 to find out how many thousands of colors it had, and if
I might want to go ahead and consider it after all.  Then I read this
(in Bitmap.Config):

  This configuration may be useful when using opaque
  bitmaps that do not require high color fidelity.

There's no way this fits into a camera app primarily geared for serious
photography, looking at adding diffusion filters to soften faces, fog
filters (you can do a LOT with a low fog, moderately deep blue filter,
and the right scene/environment), and so on.  Think of it like going to
any of the planet's beautifyl natural wonders, with a camera.  Which
would you rather have (and this is based on film):  a point and shoot
35mm with the cheapest and crappiest film you could buy, or a Nikon F4
35mm with Kodak Ektar Professional 100 ASA film?  Yeah  :-)   I
thought of that comparison a few hours ago, and it fits, even though it's
film, not digital[1].

Thanks,
   --jim


[1] OT:  I still prefer film for some photography, at least, until I
have the money to get the latest---whatever is the latest at that
time---Nikon professional-class DSLR.  And maybe still even then,
unless, by that time, digital has more density and color depth
than pro-quality film like Ektar Pro, which can literally be enlarged
to WALL sized without a hint of grainyness (pixelation for digital).
In fact, even its old non-pro predecessor, Ektar 125, which I
discovered around 1990 or so, could be.  I saw it first-hand, and it
was incredible (and it was a BIG wall).  But that is WAY off-topic,
so I'll end this bit here.

I doubt that.  I'm working with full-sized and near-full-sized images
(3 MP//2048x1536 or 5 MP//2592x1944) and those are around 750 kB and 1.1
MB, respectively (give or take a few hundred kB).  I can't remember which
I was working with at the time, but whichever one it was, logcat showed
the system allocating 10 MB for it.

For a jpeg to be that small, and taket that much memory for a bitmap, it
would have to be one huge, and extremely plain (solid color, perhaps?)
to be that compressible.

But those are the size bitmaps I'm running into, trying to give users
the full resolution of their respective cameras.  But processing the
entire image PLUS FILTERS at the same time is crashing beyond hard
limits on per-app memory (which, from what I read in an one of several
dozen old posts while trying to find the answer to my questions, both
before and after posting here, is 16 MB, period).

I've read that, on 3.0 and up, you can allocate more heap for the image
(and I've seen in logcat where my A500 does).  I've also read that images
aren't processed in that part of the memory (but like I said...).  I've
read so much conflicting information now it's insane (and I soon will
be).  Some of the Dev Guide that looked helpful even pointed me to a dead
link **within the dev guide itself**.  :-)

And while I'm here, one of the most common answers I've read so far is
simply use less memory.

Uh huh.  Well, that's exactly what I'm asking how to do, with the
added desire to allow the user to keep the full resolution.  It just
seems wrong to ask someone using a camera app that's both for the
serious and goofy types of photography, who has an Android with far
more than my 5 MP, that they can't even use 5 MP with my app.  I
would be laughing myself out of the Android developer world LONG
before everyone else got to it (and they would).

To lower memory usage, one of the things I've done is to put in a
bmp.recycle(); and bmp = null; right after the final usage of
every bitmap (except the one being returned, which I assume is
recycled after it's returned).  Unfornately, doing this results in
a Force Close, griping that I've tried to use a bitmap that's already
been recycled.  Meaning (as I understand it, at least) that it's either
executing lines of code in reverse order, or it's griping about it having
been recycled in the PREVIOUS use of that method.

I also tried the 3.0+ option, android:largeHeap=true, in the Manifest,
but still got the same out of memory error.

Perhaps there's some method of processing the photo and filter bitmaps in
chunks in a way I'm not aware of?  Something that doesn't eventually end
up right back at an eventual out of memory error?  Or some other method?

Someone?  Anyone?  Please.

What color depth are your images at?

3 MP (milli pixels?) at 24 bit per pixel, RGB_888, is 9 megabytes.

Not 750 kB and 1.1 MB.

ARGB_.  Again, when working on a camera app that's intended as much
for serious photography as the goofy side, why shoot myself in the foot
by immediately throwing image quality out the window?

 3 MP (milli pixels?) at 24 bit per pixel, RGB_888, is 9 megabytes.

No...the person who replied had written it as mb ... I corrected it
before replying to it.  I don't think there is such thing as a mp (or
a mb, for that matter ... and if there is, I'd LOVE to know what use it
is).

 5 millipixels at 24 bit is 15 megabytes.

I think you meant MP.  :-)

 Not 750 kB and 1.1 MB.

And since he'd referred to JPG sizes, that's what *I* was referring to,
not bitmap sizes (I think I included bitmap sizes in there, as well, but
specified bitmap, not jpeg.  And yes, I did two samples, one at each
resolution, both saved as a JPG, and those WERE the respective file

I'm not saying you dreamed those up, sorry, no offence meant.

But since we seem to be discussing memory usage, not disk usage, the 
compressed size is irrelevant.


And 5 megapixels at RGB_ is 32 bits per pixel or 20 megabytes in 
RAM, if stored as an uncompressed pixel array.

side-tracked by jpegs, not the bitmaps that I'm asking about how best to
handle to allow full resolution (if that's even possible), if the above
is true, then ARGB_ must not be 24-bit color, because again, NONE of
my 5 MP ARGB_ photos have been over around 1.3--1.4 MB.  Note that
I did NOT say 15 MB.  And if that IS true, the developer's guide needs
to be corrected, because I seem to recall it saying that ARGB_ IS
24-bit color.  Personally, though, I think your jpeg size of 15 MB is
on the high end, and the dev guide is right.

Again, just to make sure...I was responding to a post about JPEG sizes,
NOT BITMAP SIZES.  And I am NOT pulling these file sizes out of my ass,
I'm getting them directly from jpeg images in /mnt/sdcard/DCIM/camera.

Re: [android-developers] need help working with very large (photo) bitmaps

[Streets Of Boston]

The size of the JPG/PNG file has almost nothing to do with the size of the 
corresponding image in memory.
An RGB_565 takes 2 bytes per pixel (5+6+5=16bits=2bytes). An ARGB_ 
takes 4 bytes per pixel.
This means a 5MPixel image will take 5M*2 = 10MByte in RAM when using 
RGB_565 or 5M*4=20MByte in RAM when using ARGB_.

I have an image editor in the market and I managed to process full-sized 
images, reverting back to RGB_565 when necessary.
My image editor only applies *linear *filters. I.e. filters that modify 
every pixel in an image the same way, regardless of the pixel's position or 
its neighbors. This allows my app to chop up large images into smaller ones 
and deal with the smaller ones one by one. If not, i would need, at some 
point in time 2 copies of the image: The original and the modified.

 ARGB_.  Again, when working on a camera app that's intended as much
 for serious photography as the goofy side, why shoot myself in the foot

  3 MP (milli pixels?) at 24 bit per pixel, RGB_888, is 9 megabytes.

 No...the person who replied had written it as mb ... I corrected it
 before replying to it.  I don't think there is such thing as a mp (or
 a mb, for that matter ... and if there is, I'd LOVE to know what use it
 is).

  5 millipixels at 24 bit is 15 megabytes.

 I think you meant MP.  :-)

  Not 750 kB and 1.1 MB.

 And since he'd referred to JPG sizes, that's what *I* was referring to,
 not bitmap sizes (I think I included bitmap sizes in there, as well, but
 specified bitmap, not jpeg.  And yes, I did two samples, one at each
 resolution, both saved as a JPG, and those WERE the respective file
 sizes.  I didn't just dream those up.  Oh, and *NONE* of the photos
 I've taken, even at 5 MP, ended up being 15 MB jpegs (at least, none
 so far).

In that case...

What Streets of Boston said.

And if your filters need some amount of neighbouring pixels, you may be 
able to use overlapping slices, provided you're real careful with how 
you do the calculations in the overlapping parts.

Jumping in kind of late here, but if memory is a huge deal couldn't you pass
the image to a web service that will then handle all the manipulation then
return the image URL, download it ,save it then clean up the file from the
server via another REST request? And do this on images larger than X.

Re: [android-developers] need help working with very large (photo) bitmaps

[Streets Of Boston]

Dealing with ARGB_ full-sized images may just not be possible for 
certain devices (e.g. 5MPixel images taking 20Mbyte of memory, not leaving 
much room for anything else).
Unless you can decode the byte[] data from the Camera yourself... this 
would mean writing your own JPG decoder that would allow you to process 
this byte[] data in smaller chunks, each chunk one at a time. 

Say you won't write your own decoder. :-)

That leaves you with 2 options:
- Reduce the image size: Subsample
- Reduce the image color depth: Dither.

Subsample: Create a bitmap from the byte[] 
data: BitmapFactory.decodeByteArray and set 
BitmapFactory.Options.inSampleSize to value larger than 1 (prefrrably to a 
power of 2)
Dither: Create a bitmap from the byte[] data that has the RGB_565 encoding 
and use dithering to avoid banding.

Now you have a Bitmap from the BitmapFactory.decodeByteArray call.
If creating the other (blending) bitmap would cause OutOfMemory issues, 
chop up both the camera Bitmap.
See 
Bitmap.createBitmaphttp://developer.android.com/reference/android/graphics/Bitmap.html#createBitmap(android.graphics.Bitmap,
 
int, int, int, 
int)(Bitmaphttp://developer.android.com/reference/android/graphics/Bitmap.html
 source, 
int x, int y, int width, int height) 




 
Save the byte[] data from the camera into file directly (this is your JPG 
file).

 I doubt that.  I'm working with full-sized and near-full-sized images
 (3 MP//2048x1536 or 5 MP//2592x1944) and those are around 750 kB and 1.1
 MB, respectively (give or take a few hundred kB).  I can't remember which
 I was working with at the time, but whichever one it was, logcat showed
 the system allocating 10 MB for it. 

 For a jpeg to be that small, and taket that much memory for a bitmap, it
 would have to be one huge, and extremely plain (solid color, perhaps?)
 to be that compressible. 

 But those are the size bitmaps I'm running into, trying to give users
 the full resolution of their respective cameras.  But processing the
 entire image PLUS FILTERS at the same time is crashing beyond hard
 limits on per-app memory (which, from what I read in an one of several
 dozen old posts while trying to find the answer to my questions, both
 before and after posting here, is 16 MB, period). 

 I've read that, on 3.0 and up, you can allocate more heap for the image
 (and I've seen in logcat where my A500 does).  I've also read that images
 aren't processed in that part of the memory (but like I said...).  I've
 read so much conflicting information now it's insane (and I soon will
 be).  Some of the Dev Guide that looked helpful even pointed me to a dead
 link **within the dev guide itself**.  :-) 

 And while I'm here, one of the most common answers I've read so far is
 simply use less memory. 

 Uh huh.  Well, that's exactly what I'm asking how to do, with the
 added desire to allow the user to keep the full resolution.  It just
 seems wrong to ask someone using a camera app that's both for the
 serious and goofy types of photography, who has an Android with far
 more than my 5 MP, that they can't even use 5 MP with my app.  I
 would be laughing myself out of the Android developer world LONG
 before everyone else got to it (and they would). 

 To lower memory usage, one of the things I've done is to put in a
 bmp.recycle(); and bmp = null; right after the final usage of
 every bitmap (except the one being returned, which I assume is
 recycled after it's returned).  Unfornately, doing this results in
 a Force Close, griping that I've tried to use a bitmap that's already
 been recycled.  Meaning (as I understand it, at least) that it's either
 executing lines of code in reverse order, or it's griping about it having
 been recycled in the PREVIOUS use of that method. 

 I also tried the 3.0+ option, android:largeHeap=true, in the Manifest,
 but still got the same out of memory error. 

 Perhaps there's some method of processing the photo and filter bitmaps in
 chunks in a way I'm not aware of?  Something that doesn't eventually end
 up right back at an eventual out of memory error?  Or some other method? 

 Someone?  Anyone?  Please.

Admittedly, there will probably be some devices that absolutely will face
limits when using the filters (and probably matrix stuff for brightness
and contrast adjustments in post, too) that I'm providing in my app.  But
I am determined to miinimize that to the best extent possible.  My intent
is to make this a serious camera app, and that means maximizing image
quality relative to the device's camera.

What I'm planning to do, after figuring out exactly HOW I'll be doing the
blending, is to work out the total memory required, and then use either
getLargeMemoryClass() or getMemoryClass() to find out if the user has it.
If they simply can't support it, advise them that the original file was
saved, but the processed one will have to be resized to continue.

I seem to recall, either yesterday (while I was sick and my mind was
really foggy) seeing a suggestion, whether in private e-mail or old
posts, I'm not sure, about saving the jpeg file in chunks, too, and I
REALLY have no idea how to do that.

 Say you won't write your own decoder. :-)

You won't write your own decoder.  :-)  (sorry, couldn't resist)


 That leaves you with 2 options:
 - Reduce the image size: Subsample
 - Reduce the image color depth: Dither.

I'd rather limit size than color.  A smaller, but still having rich, full
color is far more likely to be accepted than a larger, yet lower-quality
image.  But I could use a 16-bit (plus Alpha, so somewhere between
RGB_565 and ARGB_) for the filters.

 Subsample: Create a bitmap from the byte[] data:

Already doing that for processing with the filters (also bitmaps).

Side question:  why, after I'm finished with byte[] data, and I set it
to null, does it still seem to sit there and chew up memory?  Also, on
a related note, I have a couple of bitmaps in one method that are
initially re-sized and should be recycled to protect the rest of that
method (only really matters when handling the BIG bitmaps).  But...when
I try that, it causes a force close, saying I'm trying to use a bitmap
that has already been recycled (I'd just copied it to another, and
was done with the original...not using it again in the current call
to that method).  Ahy idea what's going on there?

 BitmapFactory.decodeByteArray and set
 BitmapFactory.Options.inSampleSize to value larger than 1 (prefrrably
 to a power of 2)

Ok, this is something I'm not familiar with.  So does byte[] data
need to hang around, then?  Or am I creating a bitmap and tossing
byte[] data?   Sorry if I sound like I have no idea what we're talking
about on this part, but frankly, I don't.  In the process of getting as
far as I already am on this app, I've learned *FAR* more (so much it's
measured on a log scale) about Android programming than in all of my
previous apps combined...and then some...and I'm still learning, so
please bear [is that the right spelling in this context?] with me.


 Dither: Create a bitmap from the byte[] data that has the RGB_565 encoding 
 and use dithering to avoid banding.

Again, RGB_565 + Alpha, whatever that is, will work for the filters, but
not for the photo.  I'd rather limit its size if that's the only option.

 Now you have a Bitmap from the BitmapFactory.decodeByteArray call.

 If creating the other (blending) bitmap would cause OutOfMemory issues, 
 chop up both the camera Bitmap.

Ok.  I already have the filter bitmap in 640x480.  Is there a way to
process the larger bitmap pixel-by-pixel, using that smaller one, scaled
up in the math?  And, how do I blend (add) the color values for each
pixel?  Or do I enlarge chunks of the smaller bitmap (in relative-sized
chunks from the small one) to blend with the bigger one?

And here's a question that might work (or might be an incredibly bad
idea).  If there's a way to save a raw data file, could I, perhaps,
create the photo's bitmap, split it into chunks (or do those at the
same time?), then save each chunk into a raw data file.  Then do the
same for the filter bitmap.  Next, call another Activity with the
filenames passed with the Intent, and have it process each pair, one
at a time, save the result, recycle everything, reload the next, and
repeat.  And then, load the combined chunk data files, combine into
one bitmap (now I REALLY don't know how I'd do that, unless via paint
and the canvas would work---might still have to load one chunk at a
time and release its data immediately when done with it) until finished,
then save the bitmap to a jpeg, and return from that Activity to the
main activity.  Would something like
