[android-developers] Android Application Native Memory Leak Debug Problem

[Harris Huang]

Hi  guys,

I am tracking a native memory leak issue for a 3rd-part app on our android 
platform.

Environment:
1 Android 8.1 
2 user_debug
3 libc_malloc_debug.so exist

I got  a 
resource(https://source.android.com/devices/tech/debug/native-memory) from 
google that how to debug the native memory leak.
followed the steps described:

1 adb root
2 adb remount 
3 adb shell setprop wrap.com.xxx.xx.xxx 
'"LIBC_DEBUG_MALLOC_OPTIONS=backtrace logwrapper"'
4 adb shell getprop | grep wrap(the output 
shows that configuration was successful)
5 adb shell am force-stop com.xxx.xx.xxx
6 adb shell am start -n com.xxx.xxx.xx.xxx/.MainActivity
7 logcat -d | grep "malloc_debug"(can't find the 
"/system/bin/app_process64: malloc debug enabled")
8 operate the app, and try to duplicate the native memory leak
9 adb shell am dumpheap -n pid /data/tmp/local/heap.txt
10 adb shell cat /data/tmp/local/heap.txt
 
The heap.txt file is 0 byte.  I  don't know why i dump an empty heap file? 
anyone got the same issue?
please help.

Thanks

[android-developers] Android Application - error while opening URL that uses WebRTC in WebView

[Shubham Pratap]

I am working on developing an Android application, in which I want to open 
a URL in WebView. Now, if I open a simple URL in WebView (like 
www.google.com) is works just fine. But I want to open a URL which uses 
WebRTC (Web Real-Time Communication) which errs stating: "Looks like you 
are using unsupported browser version". I searched on google.com and found 
that WebRTC starts supporting from Android 5.0 (API level 21) and higher.

My version of Webview is:

using webView.getSettings().getUserAgentString() i get my webview details.


("Mozilla/5.0 (Linux; Android 5.1.1; Nexus 5 Build/LMY48B; wv) 
AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/43.0.2357.65 Mobile

Sorry, I just found it is possible:

http://www.technotwinkle.com/acer-launches-21-inch-android-pc/

just use the normal layout as the phone, and it will be projected/expanded
on the monitor automatically.   Have tried it from Sony Ericsson to LED TV
as well, seemless.

[android-developers] android application with ipv6

[Bryan Teo]

Hi.

How do i link ipv6 together with a mobile application device such as 
android? I have a project given by the lecturer with 0 notes as reference. 
I have to combine both of them together, however i dont understand how to 
link them together and i dont see how it works. Hence, i would ask for any 
links or explanation or reference notes for such application. I have been 
googling out such examples and codes for reference and i have not even 
found one good reference link.

Thank you.

[android-developers] Android Application Update is becoming overhead...

[Arunprasad Rajkumar]

Hi All,

Suppose I have a Android Application in size of 50MB, if developer fixes a 
major bug  fix requires to change only one java class file which sizes 
about 1K. If update is made available then App user has to download the 
entire 50MB size from store. It will be unacceptable when user have limited 
data connection.

Is there any way to update only the updated class file?. I think it is of 
the advantage of Java  We are losing out here. Please ignore if it is 
really a bad question.

[android-developers] Android Application Load Time

[Giang Hoang]

Hi,

I would like to measure Android application load time across different 
platforms.  For application that I have source, that could be done by inserting 
log print outs with time stamp at the beginning of onCreate() and the end of 
onResume(), or through instrumentation.  However, I don't know what to do with 
applications that I don't have source.  Is there any tool that would allow me 
to recognize when these function calls start and finish?

Thanks,

Giang

[android-developers] Android application StartUp Internals

[Mansoor]

Hi all,
I am very much interested to know how an android application
starts.After much googling I understood something but not fully.

Below some of my observations:

1.When i click an application icon from launcher ,System look for
activity with intent action main and category Launcher and starts
that activity.
   *I need some more clarity regarding who launch main activity or
who
filtering main activity from others(I think package manager does).

2.Once Activity is launched there will be no windows associated with
that application until i call setContentView(layout id).

3.When i call setContentView(layout id),Activity creates a new Window
inance and this window has some default root layout to which we set
our layout .
 *I think this window have a Surface instance and is associated with
native Bitmap ?Did this surface have a Canvas wrapper over native
bitmap ?

4.Once Layout is attached to Window ,This window is added to Window
manager.

5.Window manager gives gives all window(having Surface) on screen to
Surface Flinger.

6.SurfaceFlinger based on visibility of window set pixels in
FrameBuffer and displays to screen.

I am not sure whether what i said above is right or wrong.Please
correct me if my understanding is wrong.
Also add extra processes happening whilhe application start up.

Thanks and have a Nice day :)

No. The launcher already found the main/launcher activity, which is
why the icon appeared in the launcher.

Yes.

 2.Once Activity is launched there will be no windows associated with

No. There will be a window associated with the activity regardless of
your call to setContentView().

 4.Once Layout is attached to Window ,This window is added to Window
 manager.

 5.Window manager gives gives all window(having Surface) on screen to
 Surface Flinger.

If you care about any of this, you are on the wrong Google Group.

[android-developers] Android Application Crashes at Deployment

[duadinam]

Hi All

I'm working on Android project that crashes when it is deployed. Other
projects in the same workspace work fine. I increased the RAM usage on
the AVD that I'm using to 1 GB. I don't think there is a memory leak
because it seems to work on other peoples computer.

I'd like to use the Memory Profiler, but the project crashes before
launching, and I can't reach the Logcat files.

Right now I'm using eclipse, is there a way for me to launch it using
ANT or the command line, where I can execute it step by step and find
where the crash is happening?

Any help would be greatly appreciated.

Thank you,

David

[android-developers] Android Application installed from Eclipse or adb

[Chris White]

For some reason when I Run/Debug the application from eclipse the
application will pull up just fine in the emulator and I can
successfully connect and debug if need be. If I try to relaunch the
application outside of eclipse though, I receive a Toast message that
states App isn't installed when trying to launch. The application
shows fine in the Apps list of the device. I thought maybe eclipse was
screwing something up (hard to believe i know...), so i copied my
entire bin directory to the platform-tools directory (for simplicity)
and ran adb install mypackage.apk after completely uninstalling the
application on the device itself first. Once again, the app gets
listed in my Apps list, but when I try and execute it, I recieve The
app isn't installed toast message. The only way I can get this app to
run is via eclipse run/debug. Any ideas?

Re: [android-developers] android application gets killed in stand by mode

[Harri Smått]

Hi,

If there's a forced close from time to time, doesn't it indicate your code 
crashes during ramp down of your application for sleep mode, does it? Running 
application ought to be running once user returns from sleep mode without any 
extra work on your side. But for restarting your phone - do you really want it 
to be first thing the user sees?

Do a bunch of other smaller apps that will help teach you what you need to
know to do this.
If you're new to android and have to ask how to do what vaguely sounds

[android-developers] android application which communicates with one central database?

[mark kelly]

Hi
Im new to android development. The application I would like to write
needs to have one database on a server, which all instances of the
application needs to communicate with simply. So there will be no
database on each android, just an ability to send info to the central
database. Can anyone point me to tutorials or resources on this sort
of development? A lot of the tutorials i looked at just seem to have
native databases on each android...
Thanks

Re: [android-developers] Android Application to Install a font

[Mark Murphy]

Your application can use a font that is packaged with it or is
available on a local filesystem (e.g., external storage).

You cannot install a font system-wide, except via custom firmware or
perhaps via rooting.

Re: [android-developers] Android Application Development

[Matheus Bodo]

I don't know if I undertood your question, but the way you wrote your code,
it will write the source code of the page in the Log.

If your intention was to open the browser to load the url, you should do it
via Intent.

This may help you:

[android-developers] Android Application Development

[Lakshmi Priya]

I am developing an app in android and the search button in the
application needs to be linked to a website.  Instead of the website
opening up on the android emulator the source code appears.  Can
anyone help me with this...

I have pasted the code below...

package com.apache;

import java.io.BufferedReader;
import java.io.InputStreamReader;

import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;

public class ApacheConnection extends Activity {

Button bt;
TextView textView1;
TextView textView2;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
bt = (Button) findViewById(R.id.button1);
textView1 = (TextView) findViewById(R.id.editText1);
textView2 = (TextView) findViewById(R.id.editText2);
bt.setOnClickListener(new OnClickListener() {
  @Override
public void onClick(View v) {
// TODO Auto-generated method stub
textView2.setText();

 try {
/*Apache HttpClient Library*/
HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet(http://google.com;);
HttpResponse response = client.execute(request);
/* response code*/
BufferedReader rd = new BufferedReader(
  new
InputStreamReader(response.getEntity().getContent()));
   String line = ;
while ((line = rd.readLine()) != null) {
  Log.d(output:,line);
   }
  } catch (Exception exe) {
   exe.printStackTrace();
  }
}
 });

}
}

LinearLayout xmlns:android=http://schemas.android.com/apk/res/

android:orientation=vertical
android:layout_width=fill_parent
android:layout_height=fill_parent

TextView

[android-developers] Android application blocked by Market for Motorola Xoom

I've got an android application which runs on a Motorola Xoom, but can

This apk requests 3 features that will be used for Android Market

This apk requests 1 native platforms that will be used for Android
Market filtering

This application is only available to devices with these features, as
defined in your application manifest.

This application is available to over 411 devices. Show devices

And when I click on the Show devices link, the Xoom does appear in
that list. As you can see I already have the telephony feature set to
false and the application is still blocked.

Any advice will be greatly appreciated

That's it? Hardly seems worth the effort if you ask me. But hey, it's your
app and your time.

[android-developers] Android application pause/resume state.

[Dalvin]

Hi

My question is can i get to know when the entire application gets 
paused/resumed start/stop etc.
For example if i have 5 activities in my application. Whenever any activity 
gets paused/resumed android notify the activity by calling the 
onPause/onResume methods.

So there are two possible scenarios when my activity gets paused.
1. My activity-2 gets paused because my activity-3 gets invoked.
2. My activity-2 gets paused because of some outside activity like incoming 
call.

Here I am interested only tracking when my activity gets paused by outside 
activities not my own application activities.

So is there any android provided solution for this or do I have to write my 
customized solution.

Thanks
Dalvin

I would question why you you need this? Perhaps there's a better way to
achieve what you're actually trying to achieve.

[android-developers] Android Application Settings Problems

[MattClark]

I am trying to use application preferences in my app, following this
at AndroidDevelopes:
http://developer.android.com/guide/topics/data/data-storage.html

my code is as follows.

imports:
import android.content.SharedPreferences;

declarations:
public String PREFS_NAME = MyAppSettings;
public SharedPreferences settings = getSharedPreferences(PREFS_NAME,
0);


the program compiles fine, but when i deploy it to my device it errors
only if the second line of declarations is in place. I have no idea
what the problem is. i have tried (PREFS_NAME, 0)(MyAppSettings, 0)
(PREFS_NAME, MODE_PRIVATE)(MyAppSettings, MODE_PRIVATAE) and
every time it still errors on the device.
any and all help is greatly appreciated.
thanks
~Matt

Maybe the first thing you want to consider is the popular degree of your

[android-developers] Android Application without a Main Activity?

[AndroidDevTime]

Is it possible to have an Android application that runs without a Main
Activity?  I have mostly Widget--Service communication and I really
don't want a Main Activity to show most of the time.  But anyway my
question is can this be done?  Does an application have to have a Main
Activity? Can it start and run invisibly or does it always have to
have screen visible when its running?

Re: [android-developers] Android Application without a Main Activity?

[Kostya Vasilyev]

You don't have to have the main activity in your application, or any
activities at all. Check the manifest and remove the launcher-specific
intent filter from your main activity if you don't want it to show up in the
application list.

However, my personal observation is that doing this can cause user confusion
and a bunch of 1-star duznt opin type comments in Market.

[android-developers] Android Application Cache

[Tommy]

Hi everyone,

I'm trying to understand the way android handles my application cache
dataSome times i'll go in there and the cache directory is 6-7mb.
What type of data is stored there? Is there a way in the mainifest I
can say don't use cache or clear cache at Xmb ?

Thank you for your time and help,

Tommy

Whatever you put in there using getCacheDir().
Also, I think I've read that WebView throws stuff in there, so maybe if
you're using one, that's the problem?

Doesn't look like it. But if you determine what's putting stuff in the cache
to begin with, you can probably stop it from doing that. Or add your own
code to check the cache size and delete older entries or everything
entirely.

Check out the docs for WebView.

For obvious security reasons, your application has its own cache, cookie
store etc.

Yeah I found a place to where you can do webview.clearCache(True/False)
-Local Disk Data

 

Im going to try this and see if I can keep that cache directory under
control if not I'll look at other options or things that would be causing it
to grow.

[android-developers] Android application Session timeout

[AUandroid]

Hi guys ,

1) I am trying to have a session time out feature in my application. I
want to display the login screen after a time   out   period. I
searched around for pointers for this problem and it seems like the
preferred way is to start and stop timers at onREsume and onPause(),
and start the login activity if the time out has occured.
 Is this is a optimal way? I would appreciate any other ideas to
achieve this.

2) After the timeout  login screen is displayed, if the user hits the
back button, I want to display home, and not any of the previous app
activities. When the user hits on the app icon again, she must be
taken back to login screen to resume. There are some security issues,
user must not be able to visit any activities unless the login is
authenticated. The timeout must be handled at client(device) side, as
this app is doing only pull operations.
 - I thought of using the clearTaskOnLaunch, which might take care of
using going back to home if back button is hit. But I guess user
cannot go back to the activity he/she was doing. Any ideas

Thanks,
-vk

Why do you even need to bother what version user upgraded from? The
simpliest approach could
be i.e. to store in app preferences app versionCode. On launch, check
if that prefs value exists.
if it does, check if value is lower than your versionCode, if it is,
user upgraded = show changelog.
If there's no prefs entry = show changelog as it is definitely old
code which did not store
such entry. Afterall store current versionCode so on next launch you
won't show changelog
as versionCodes would be equal.

[android-developers] Android Application with embedded e-reading

[Brinson Tatum]

I am pretty new to mobile development and I'm struggling with how to
go about accomplishing one task.  The application that I'm working on
is for a state government agency and is going to include a variety of
features, one of them the ability to read a handbook.  I want to make
the user experience as nice as possible by making the handbook
readable in a similar as other e-reading software, but I'm at a loss
as to how to accomplish it.

I started by using a WebView and looking at packaging the handbook
into an epub file and displaying the contents in the WebView.  On the
surface, displaying the content was pretty easy in the webview.  The
challenge is with making it not have the user scroll down.  I would
rather them flip pages like a standard e-reader.  I'm not looking to
build a full featured e-reader, but I would like the basic
functionality.  It seems the WebView may not be the best UI component
for this task, but maybe it is.

Any suggestions or ideas would be MUCH appreciated!

Thanks

[android-developers] android application error reports

[nick]

Are there any details on this? There is an 'official' blog post, but
that tells us very little.

Is this a Froyo only feature? Or does it work for certain devices
only? I've being getting
reports from Motorola Droid for some time, and that are supposedly
running Eclair only
(at the time). I couldn't trigger it on my NexusOne though with stock
Eclair and Froyo.

BTW, it would be nice to get the Android version in the crash report.

Anyone care to shed some light?

Sure, you can use any design pattern you like in your app. Some will work
better than others, of course, given the way the Android Framework is
designed and depending on what you're trying to do.


 I this I mean to say I have a controller which is called by activities and
 controller decides which activity to show something on this lines. Is this
 good design?


Maybe? Your one sentence description of what you're trying to do is
insufficient to determine whether it's a good design. No one will really
be able to answer this without knowing the full scope of you app and what
you're trying to accomplish.

And even then you will get a different idea of a good way to do things
from each programmer you ask - each one thinking they know better than the
others =P

[android-developers] Android Application and Desktop Application Communication

[Boardy]

Dear All,

I am doing some research in developing an application for the Android
platform that will transfer data to and from the android device and
PC. I would like this to be done via USB.

The android application will store information within the built in
SQLite3 database.

I will also write a program either in Java or C# for the Windows PC. I
want to be able to connect the phone to the PC via the USB connection
and from the program on the PC get the data out of the sqlite3 on the
android device and store the information in a sqlite3 database on the
PC. I also want it to do it the other way round, i.e. get the data out
of the database on the PC and store the information in the database on
the Android device.

Is this idea at all possible.

Thanks for your help with this problem.

[android-developers] Android application

communication with other Bluetooth devices (not Android). I'm using
the Bluetooth API.

I'm able to scan nearby devices, but when I select one to connect, I
get the following error:

E/BluetoothEventLoop.cpp(   92): onCreateDeviceResult: D-Bus error:
org.bluez.Error.AlreadyExists (Device already exists)

but the device isn't paired.

Which UUID do I need to use?I'm trying with this:

BluetoothDevice device = btadapter.getRemoteDevice(address);

String s = new String(RFCOMM);
byte[] identifier=s.getBytes();
uuid=UUID.nameUUIDFromBytes(identifier);

BluetoothSocket socket =
device.createRfcommSocketToServiceRecord(uuid);
socket.connect();

but the connection fails

[android-developers] Android Application memory usage monitor

[Mihai Dumitrache]

Hello,
I am trying to get the memory usage for every application at different
periods of time. I have checked the docs / threads / forums, and i
only found that you can get the total available memory value,  but i
could not find in the sdk an api call for getting the memory used by a
single application.

I know that one way to do this is by reading the values from /proc/
pid virtual file system but this is painful for the device cpu.
Can you help me figure out how to solve this problem ? Or does anyone
know how settings - applications - manager applications read the
memory usage values.

Thank you,
Mihai

[android-developers] Android application trying out rss feed read using Rome. Getting exception ExceptionInInitializerError

[MCON Dev]

Hello All,
I am trying to write some test code to receive RSS feeds. I am using the
ROME api's. But I am getting a exception when executing the following line
of code
  SyndFeed feed = new SyndFeedInput().build(reader);
I googled this exception and found the following. I dont know if thats
helpful or not. Please advice me on my next steps.
Ok, I figured it out after traversing through the Rome code.
ClassLoader isn't supported by Android's DalvikVM. Is there an
implementation of this project that doesn't use ClassLoader?

[android-developers] Android Application for Public Service to report, dispatch and resolve repairs

[Richard R]

http://code.google.com/p/fixxit/

I had an idea to use Android in the public space to report public
works and other problems that need repairs.

Android provides a great tool to document and locate problems. Google
APIs like Maps and Appengine can link these reports to help direct
efforts to make the public space a better place to live.

Unfortunately I'm a Java rookie and so lack the skills to even start
the coding at this point.

I welcome the contributions or suggestions of you advanced developers
to help get this open source application started.

Or if such an application already exists, please let me know.

Thank you.

Hi All,

Can anyone tell me if when you upgrade your marketplace application if
it then appears at the top of the list of applications by release

[android-developers] Android application without UI

[Javier Segura]

Hello All,

I've written a simple app for android that changes the content of a
System Setting. For use it I create a simple Activity that makes the
job. When I execute this app it shows for less than a second a black
ui (the layout of this activity). There is any method for refactor my
app in a windowless way?

[android-developers] Android application, with native code

[roy.vi...@googlemail.com]

Hi,
I need to implement an Android application (with Activity, Intents and
all that jazz), which can be deployed with native code (legacy native
C code).
The Android application will call a single method in the native code
during runtime.

Is that possible and how?

Happy new year :-

[android-developers] Android Application for salesforce.com

[dai]

Ciao, gentlemen. I've started Android open-source project targeting
Salesforce (http://www.salesforce.com/) using Apex API (http://
www.salesforce.com/developer/).

This app is to connect to salesforce thru soap base web serivce
(really really fandamental part :)), and now I'm planing to open the
source code to do enhance with lots of folks.

I've post my code to google code page below. You could download and
run on google android.
http://code.google.com/p/salesforceandroid/

Salesforce is B2B saas/paas company that deals with sfa, marketing,
support, hr, mainly.

This app is really um-matured. This is read-only for now.

[Avaialble Salesforce Standard Object on my app]
- Event
- Task
- Lead
- Account
- Contact
- Case
- Opportunity

- Chart Viewer (google chart api)
- Web Viewer (Visualforce viewer. you could see 2 visualforce pages if
you log in as hard-coded user)

With this app, username is harded coded but you could change it to
your user name that has Salesforce API enable option.

If you are interested in it, please come in the page :
http://code.google.com/p/salesforceandroid/
Some gentlemen said to me to help the project :)

Thank you very much,
