RE: [android-developers] add text to each image in gridview

[Trung Liem Vo]

Hi,

Your code is correct. 

Can you use each item contain imageview and textview. So your image will
have the label.

Best regards,
Trung Liem Vo

Subject: [android-developers] add text to each image in gridview

Hi, everybody

  I want to add label for each image in gridview how to do
this? I had tried with following code but it shows only images and not
text.

my xml file as:


http://schemas.android.com/apk/res/android";
android:id="@+id/myGrid"
android:text="Pramod"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

android:columnWidth="90dp"
android:numColumns="auto_fit"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:stretchMode="columnWidth"
android:gravity="center"

/>

how to do this.
Thanks

[android-developers] Problem with textview(WebTextView)

[yogi]

Hi All,

 I am have a problem, I created app in with webview in it.
Now when i open google.com and search a word. After that i just copy
and paste the content of the textview  again & again.
I saw that after some  repeated pastes the text is overlapping on the
with the previously existing text.
I was looking thought WebTextView.java but did not find any solution
here also for this problem.

Regards
Yogi

You definitely do not need a thread to display a progress dialog or a 
progress bar / wheel. I think using threads for this is the cause of 
your database issues, and actually you confirmed this too.


This describes progress dialogs:

http://developer.android.com/guide/topics/ui/dialogs.html#ProgressDialog

I'd recommend implementing progress feedback as described there, by not 
using threads, to see if it makes a difference.


If you use threads to handle a lengthly insert / update operation, take 
a look at AsyncTask.


Now, with this being said, opening the database from two points in the 
code (application / service) and holding it for a length of time is not 
a good idea, as you already discovered.


Consider implementing a ContentProvider for your own use (you can mark 
it as non-exported, i.e. private to your application).

I've done a lot of tidying up, now Im finding a problem between the
service and the insert commands.
The service utilises "getReadableDatabase" and "rawQuery", while the
separate updater function (user controlled) utilises
"getWritableDatabase" and "execSQL" to perform inserts.
I get errors in the log such as:

I've asked elsewhere and I've looked for solutions such as using
synchronized (Im still trying to wrap my head around that at the
moment), but ideally what I want to know is why is this error being
generated. If I can find why things work instead of what the solutions
are, I'll be a better Android programmer.
Immediately before the insert, I check to see if the database
isLockedByOtherthreads(), but the answer is false. However it seems
when I open/read the database in the Service, Android then fails to be
able to do the Insert in the Activity and errors that the database is
locked.
Why does a read lock the database?
What is generating the lock?
Why does isLockedByOtherThreads() return false and then the Insert
fail?
Perhaps "database is locked" is an erroneous error and refers to it
not being able to generate an exclusive lock for the insert?
Is there a way to find out programmatically what locks there are on a
database?
And finally what are some solutions for this?
I presume I can do reads all over the app as I wish, but the problem
comes when I try to do a write at the same time a read is being
performed.
Perhaps I should disable the service while the update is in progress.
Or I've heard about synchronized but I really don't have any
experience with this and Im looking for some good (android related)
theory about what it is, how it works, why you do it, and how you do
it?
Thanks

Re: [android-developers] Re: Will no longer support Android 1.5

[Kostya Vasilyev]

No, I'm not disputing those numbers at all.

What I meant is - it wasn't a weird phone made by a fringe manufacturer.

The phone a Motorola Backflip - AFAIK, it still runs 1.5 outside the US, 
and the 2.1 update in the US was not an OTA, so perhaps not everyone who 
could update actually did.

How could this be? I am curious to hear how either 1) the dashboard
sampling could be that far off or 2) how popular this phone really is.
Can you post the make and model# of the phone without compromising

For now, both my apps continue to support 1.5, but a new project I'm working

[android-developers] Re: Schedule notification instead of permanently check

Good Morning!

Wow, you helped me to get it work. I create a PendingIntent with a
unique id and store the intent mapped to their IDs in a HashMap. I
collect all intents with the known id and can the cancel them using
the AlarmManager. I dont know if it is recommended and efficient to
store those intents in a HashMap, but I need the PendingIntent when
I'll cancel the alarm and it worked.

Maybe I have to optimize something, but now I understood how to work
with the AlarmManager AND multiple scheduling tasks.

[android-developers] Re: Anyone with GL experience willing to take a contract/bounty?

[Indicator Veritatis]

Spend a little more time with "The Red Book" on OpenGL, and it will
make sense to you. It takes a couple of slight shifts in your way of
thinking, but one you change gears, it won't seem so unfriendly.

That said, the "slight shifts" are easier for those of us who used
homogeneous coordinates, orientable manifolds, combinatorial topology
and other similar mathematical ideas before;)

"The Red Book" is at http://fly.cc.fer.hr/~unreal/theredbook/ and for
OpenGL ES, is not out of date, even though that free copy is for
OpenGL 1.1.

One minor nuisance: the Red Book examples assume the use of OpenGL
commands using vertex lists built by bracketing drawing primitives
with glBegin() and glEnd(), but OpenGL ES does not support these. This
is a good idea why it is handy to learn OpenGL on your desktop first
before restricting yourself to the subset available in OpenGL ES...

Re: [android-developers] Re: Schedule notification instead of permanently check

[Kostya Vasilyev]

Danny,

Android already keeps a global registry of pending intents, so keeping a 
parallel hash map should not be necessary.


To cancel an alarm, you don't need a reference to the original Java 
object, you can just construct a pending intent the same way as you did 
when setting the alarm (including the request code).


The hash table can go away with the process, while alarms persist (with 
them being inside Android). If you're relying on the map being an 
up-to-date representation of your alarms, make sure that it's correctly 
reconstructed from scratch - or get rid of it altogether.

Shouldn't that be somewhere in the Android source? I never did figure

where you should start.

One of the Google groups concerned with the Open Source Project or
with Porting is probably a better place for your question anyway.

[android-developers] Problem launching Google Goggles from camera app

[blindfold]

I'm launching Google Goggles from my own camera app through an intent,
which generally works fine, but occasionally Google Goggles refuses to
launch, popping up an error message reading

> Camera Error
>
> Cannot connect to camera. You may need to restart your device.

and after pressing OK my app takes over again and successfully resumes
its own use of the camera (no device restart, and not even an app
restart). Now of course only one app at a time can use the camera, so
I explicitly first release() the camera and set my camera object to
null before launching Google Goggles.

Just waiting for camera==null to happen automatically after a
camera.release() does not work: log output shows that the camera
object remains non-null after doing a camera.release(), and I have to
explicitly set it to null as is common practice, but after that
something is sometimes still blocking reuse of the camera. I suspect
that some camera ownership flag is still floating around deep down in
Android, but if it is not somehow exposed such that I can check for it
then it is of no use.

So what *else* can I check for to make sure that the camera REALLY has
been released and *is* available before handing control to another
camera app? Or should it be filed as an Android bug?

The problem occurs on my HTC Desire running Android 2.2. BTW, I always
do camera.stopPreview() and camera.setPreviewCallback(null) before
doing camera.release().

Thanks!

[android-developers] Preserve ListView position when using footers

[Kwisatz]

This is driving me crazy!

I have two applications with this problem, and I'm about to give up.
I'm out of ideas.

In these applications, I've constructed a pattern for the ListView
very similar to the Gmail app. I'm fetching information from the
server in small sets, and when a user scrolls down to the last
ListView position, he sees a download progress row. If something goes
wrong, that download row switches to an error row with an error
message and a button to retry the network request. When the data set
is retrieved, the ListView is updated at the bottom with the new data
set. The download view and the error view are done with ListView
footers.

So far, so good. It works greak. The problem is when the user clicks
an item in the ListView in order to go to another Activity. When he
comes back the the ListView, it resets the ListView, so that the first
visible position is always the first item of the ListView.

If I remove all the footer code, then it works as expected, and the
ListView remembers it's position when it comes back.

I use the getFirstVisiblePosition() and the setSelection() to
workaround this, although it's ugly because the ListView always shifts
a little. But even these are buggy and sometimes (about 5% of the
times) the getFirstVisiblePosition() returns 0. This just adds to the
frustration.

I'm about to give up on footers and eradicate them of my Android
vocabulary and stick with the Window title  indeterminate progress.

But... how does the Gmail app does it?! Does any one have an idea?

[android-developers] Re: google analytics jar does not seem to work now

[David Liebman]

just thought of a good question:

what URL did you use for your google analytics profile. When I did it,
I made up something descriptive. That should work, right?

[android-developers] Creating Animation List Using Bitmaps Programatically

[Amit]

Hi All,

I am trying to achieve adding the animated gifs into my application.

1- I am able to download the animated gif from server.
2- I am able to decode the animated gif (using my custom decoder) and
have a separate Bitmap corresponding to its frames.

Now I want to animate it using the frame by frame animation. As i
read, to perform the frame by frame animation the first thing that is
required is "animation-list".

I want to know how i can create the required "animation-list"
programatically containing each Bitmap as a separate frame.

Kindly Help.

Thanks & Best Regards
Amit

Re: [android-developers] Preserve ListView position when using footers

[Kostya Vasilyev]

20.01.2011 13:08, Kwisatz пишет:

I use the getFirstVisiblePosition() and the setSelection() to
workaround this, although it's ugly because the ListView always shifts
a little. But even these are buggy and sometimes (about 5% of the
times) the getFirstVisiblePosition() returns 0. This just adds to the
frustration.



Have you tried saving / restoring scroll position using pixels, rather 
than the first visible list item?


When you're leaving ListView, there can be a partially visible list item 
at the top, hence the shifting when you come back to the activity.


I'd try these View methods:

public final int getScrollY ()
public void scrollTo (int x, int y)

Re: [android-developers] Creating Animation List Using Bitmaps Programatically

[Kostya Vasilyev]

Based on the reference:

http://developer.android.com/reference/android/graphics/drawable/AnimationDrawable.html

you just create a new AnimationDrawable, then call addFrame() for each 
frame image, and finally all start() to play it.

[android-developers] Sample code for service?

[petter]

I'm looking for a complete minimalistic code sample for a service.
Does such a thing exist? I've tried, but get some errors which I
assume is related to inconsistency between my xml and java code. I'm
simply using ant and and the CLI tools, e.g. not Eclipse.

[android-developers] Re: getHitRect() returns hit to a different image item in a Customize List

[Hari Edo]

It's not clear what effect you're doing, but you will probably need
the inverse of the drawing transformation to determine the hits.
That is, if the drawing transformation is dividing by Z for depth
and perspective, the hit testing function should be multiplying by
Z to put the touch coordinates back into the button's coordinate
space.

[android-developers] Re: Anyone with GL experience willing to take a contract/bounty?

[RyanMcNally]

Here is some code:
http://code.google.com/p/rugl/source/browse/trunk/droid/DroidRUGL/src/com/ryanm/droid/rugl/util/geom/Tesselator.java
that will take a list of x,y vertex coordinates of a simple polygon
(concave is fine, self-intersecting is not) and spit out the vertex
and triangle index arrays suitable to be sent to opengl (in
GL_TRIANGLES format)

It should be pretty easy to pull out, there's only a few small utility
methods that it relies on. Failing that, the algorithm is pretty
simple and well-commented.

OpenGL is easier than you think, don't let it intimidate you!

[android-developers] Re: Could I exec some codes after my app is installed

[Jens]

Yes. Which is bad.

Adding a BroadcastReceiver to your app for something that is spammed
often enough start your app without user interaction .. eventually.

For that extra abusive touch i recommend listening for
"ACTION_USER_PRESENT" - whenever the user wakes up his device & goes
past the key guard your app will be started/notified.

Re: [android-developers] MediaPlayer not working properly - causing sounds to be truncated

Use SoundPool and keep track of when the clips end on your own. You
know the duration of the clip, since it is your clip. You know when
you are starting up the sound, because you are the one starting
playback. Hence, you know when the sound has finished playing, through
addition.

Bear in mind that Android hardware is not designed to play a "large"
number of sounds "concurrently", due to slower CPUs and limited sound
hardware. The objective of SoundPool is specifically to *not* play
sounds, via a prioritization system, so high-priority sounds get
played while low-priority sounds get dropped so the whole thing
doesn't chew up all available CPU time. MediaPlayer is not designed to
play a "large" number of sounds "concurrently" at all.

You didn't put an exception handler around the subscript operation in

[android-developers] Re: The curious case of the impossible ArrayIndexOutOfBoundsException

[RyanMcNally]

There's been no indication that the arrays could be null so far, but I
guess at this point we are fully through the looking-glass so all bets
are off.

Welcome to bizarro-world, engage null-checks for your safety,
convenience and psychological integrity.

[android-developers] Which phone for hardware testing?

[Rok]

I'm looking to support all phones back to 1.5 so am wondering what
phone would be a good one to buy to test the application on slower
CPU, lower resolution, etc.?  Something in the nature of "if it works

[android-developers] Re: Which phone for hardware testing?

[Stephan Wiesner]

Thats what I bought my SE Xperia Mini Pro for. Its not too expensive,
small enough that i can carry it around with me all the time and has a
hardware keyboard, which is great to make sure the app can be used
with it. As it has "only" 600 MHz, I use it for "performance testing",
though in many cases it is faster than my f... Samsung Galaxy S.
By now I don't support <2.1 anymore and upgraded the phone ( it is
delivered with 1.6.). I found that none of my users had older phones,
so...

With the highly detailed problem description of "working well in 2.1 sdk7

Did you try looking at the documentation? Because the Service class docs

[android-developers] How to add a Search Bar

[Lidia]

Hello developers,

I have a huge misunderstanding.

I am trying for few days to add the search bar in my application like
one from http://developer.android.com/resources/articles/qsb.html

But, I do not think I understood exactly if I can use it just for the
search i need.
e.g.:  to retrieve the typed text and return my search response,
provided from a web service.

So, basically i need just the design, not it's functionality.

Can someone tell me if i can use this bar only for my personal data,
not a general search from internet or the hole phone,
and i would appreciate link for a simple and clear tutorial, because i
couldn't found anything concrete till now.

Thanks in advance,
Lidia

[android-developers] Implement Service in one application and access in another application

[Hari Kumar]

Hi All,

Currently I am trying to access the Service which is implemented in
one application and accessed by another application. But it is not
happening.

Below I explain the code for reference, Please check it out.
Consider the implemented Service application as "Server" and accessing
the Service application as "Client".

IRemoteService.aidl:(This class is append in both the Server and
Client application)
interface IRemoteService {
int getCounter();
}

Server Application:
RemoteService:(This is Service implemented class)
public class RemoteService extends Service {

private Handler serviceHandler;
private int counter;
private Task myTask = new Task();


@Override
public IBinder onBind(Intent arg0) {
Log.d(getClass().getSimpleName(), "onBind()");
return remoteServiceStub;
}

private IRemoteService.Stub remoteServiceStub =
new IRemoteService.Stub() {
public int getCounter() throws RemoteException {
return counter;
}};

@Override
public void onCreate() {
super.onCreate();
Log.d(getClass().getSimpleName(),"onCreate()");
}

@Override
public void onDestroy() {
super.onDestroy();
serviceHandler.removeCallbacks(myTask);
serviceHandler = null;
Log.d(getClass().getSimpleName(),"onDestroy()");
}

@Override
public void onStart(Intent intent, int startId) {
super.onStart(intent, startId);
serviceHandler = new Handler();
serviceHandler.postDelayed(myTask, 1000L);
Log.d(getClass().getSimpleName(), "onStart()");
}

class Task implements Runnable {
public void run() {
++counter;
serviceHandler.postDelayed(this,1000L);
Log.i(getClass().getSimpleName(),
"Incrementing counter in the run 
method");
}
}
}
Manifest file for Server Application:



Client Application:
RemoteServiceClientDemo : (This class accessing the method in the
interface)
public class RemoteServiceClientDemo extends Activity {

private IRemoteService remoteService;
private boolean started = false;
private RemoteServiceConnection conn = null;

/** Called when the activity is first created. */

[android-developers] openGLES different behavior on different devices

[pedr0]

Hi at all,
I have some strange  behavior issues on texture-mapping with OpenGL ES
1.1

1)This is the right picture (Samsung Galaxy S):
  http://i.imgur.com/j00Zy.png

2)This an wrong picture (HTC Magic):
  http://i.imgur.com/P8NCW.png

3)This is another wrong picture (Ideos):
 http://i.imgur.com/aOAza.png

I am very disappointed for that, could someone help me?
I have mapped a texture in a  Sphere using OpenGL ES 1.1, the OpenGL
need version is write in the AndroidManifest.xml file.

In the 2th case I can read a lot of this message:

E/libEGL  ( 2372): called unimplemented OpenGL ES API

I configured the checkError flag in OpenGLViewRender, but I cannot see
the OpenGL call which
cause this message.

Thanks a lot in advance.

[android-developers] Re: Preserve ListView position when using footers

[Kwisatz]

Thanks for the help, Kostya.

The getScrollY() didn't work, but it got me started to find out a way
that I could save the pixel offset of the top ListView row. And I got
it. It's something like this:

@Override
protected void onPause() {
super.onPause();
this.firstVisiblePosition =
myListView.getFirstVisiblePosition();
this.firstChildTop = myListView.getChildAt(0).getTop();
}

@Override
protected void onResume() {
super.onResume();
this.myListView.setSelectionFromTop(this.firstVisiblePosition,
this.firstChildTop);
}

But I still have the problem that sometimes the ListView is refreshed.
I've noticed that it's sometimes after the onPause(). Very weird. So,
I did my (so far) most ugly hack EVER! I'm sincerely ashamed of this,
and I will deny that this is my code, but... it gets the job done for
now :P

@Override
protected void onResume() {
super.onResume();
this.myListView.setSelectionFromTop(this.firstVisiblePosition,
this.firstChildTop);

new Handler().postDelayed(new Runnable() {
@Override
public void run() {
 
this.myListView.setSelectionFromTop(this.firstVisiblePosition,
this.firstChildTop);
}
   }, 200);
}

Cof, cof...

[android-developers] Bitmap factory and ICC aware JPG

[Yahel]

Hi all,

I'm fighting a weird battle over here.

Using this simple code :


URL bitmapURL = new URL("http://farm5.static.flickr.com/
4069/4432443443_3ece4b42d9.jpg");
HttpURLConnection connection =
(HttpURLConnection)bitmapURL.openConnection();
connection.setDoInput(true);
connection.connect();
InputStream input = connection.getInputStream();
bitmapFromUrl = 
BitmapFactory.decodeStream(input);


I'm able to create a bitmap from the url of a jpg file. Well most of
the time.
The url included in the code is of a jpg that cannot be decoded by
bitmapfactory.

I narrowed it down to the fact that it uses an ICC color profile.
Which seems to me to be the only true difference from this other one
which loads fine :
http://farm2.static.flickr.com/1370/879345990_d778558446.jpg

I thought that icc color profile were headers and that decoders which
did not know what to do with it just ignore them. But it doesn't seem
to be the case for Android BitmapFactory.

Anyone has any idea how I could overcome this problem ?

Side note : If I feed the guilty url to a webview component, it
displays it fine with no problem. Could that be used in any way to
make a bitmap out of it ?

Thanks.

Yahel

[android-developers] RelativeLayout click events

[BuckeyeDroid]

Hi,

I have a RelativeLayout with two TextViews and a Button. Each of these
is a row. I want to be able to click anywhere on the row and get the
same effect as if I just clicked the button. Right now, only clicking
the button works. Clicking anywhere else on the row does not work.

Does anyone know how to fix this?

[android-developers] Theme/Style in custom preference

[Eric Crump]

I created a custom PreferenceActivity.  Doing so removed all the text

in a preference activity to my custom one?

Re: [android-developers] RelativeLayout click events

[Kostya Vasilyev]

A view can only receive click events inside its boundaries. So make them 
larger, by using appropriate layout options.


If you want the button to look small and respond to clicks over a larger 
area, then add some kind of layout around it with width=fill_parent, and 
set the click handler on that (make sure you use a state-list drawable 
for the background, so there is visual feedback for clicking).


For TextViews, this is not necessary - you can stretch them full width 
without affecting how they draw text.

Hi,

I have a RelativeLayout with two TextViews and a Button. Each of these

Does anyone know how to fix this?

Re: [android-developers] Re: getHitRect() returns hit to a different image item in a Customize List

[argon gold]

Hi Hari Edo,

You can view the effect I am doing in movie at following youtube link.

http://www.youtube.com/watch?v=TMaMpp8eg4s

It is on the left side a deck of cards when slide up or a fling action
happen they moves upward  at different angles and finally at one stage each
card gets straighten and at this point I have implemented a touch on that
specific card.

I'll study your suggestion and test it if it works.

Thanks & regards,

Re: [android-developers] Theme/Style in custom preference

Eric,

I recently implemented a couple of ListPreference subclasses, and didn't 
run into any issues with themes or styles, even though my preference

My code (and a brief write-up) is here:

No, there is no API on the application level.

Assistance data support is part of the GPS library implementation and
it belongs to the HAL in the Android SW stack.
That means two things: not every Android phone has assistance data
support and that you can do this as part of the porting efforts which
is a completely different scale of task.

If you have an external A-GPS receiver (USB, Bluetooth) you can use so
called "mock" location provider - create your own provider, utilize
TCP/IP to exchange data with your server, use Android's location
providers, etc.  Looks like a perfect approach for any experimental
thing.

[android-developers] Re: google analytics jar does not seem to work now

[H]

HI David, yeah, analytics works fine for me in the emulator (*)

(*) depending on the avd you use. One of my avds was built from a custom rom 
with a custom hosts file that denied access to the analytics site and my 
logcat just filled up with exceptions "unable to resolve url" every ten 
seconds. But if you use all the default Android/Google avd's, this shouldn't 
be a problem at all.

I tend to find the analytics are available about 24 hours later. It's hard 
to tell precisely, but looking at the analytics for today, I can see some 
stuff with yesterday's date on it that isn't quite as a high as the previous 
day's figures yet.

yes. But my problem is probably not the java code, but appears to be

[android-developers] Re: Sample code for service?

[petter]

Yes I looked at http://developer.android.com/reference/android/app/Service.html,
but my problem appears to be with the xml file, and not the java code
itself. Hence I wanted a complete minimalistic example to learn how
these are tied together in a service.

Re: [android-developers] Gingerbread BroadcastReceiver Issue

[Jake Basile]

I always try and assume it's my 
faultfirst,
 but I am completely without any idea as to how my code is causing the 
issue after spending q good chunk of effort searching. If I can fix this in 
my code I will; I hope it's mine because there is a 100% chance that I will 
fix it against a much smaller chance that the Android team will get to it.

I completely agree that I shouldn't need the service for this. I had no 
choice though, so I did it the only way that I could get it to work. My 
issue is that it stopped working on 2.3 with zero changes on my end. This 
means I will have to add *another* workaround (the startForeground one) so 
that 2.3 users can at least have a functioning app. This is also pretty 
terrible as it means I need to show an annoying notification icon at all 
times.

Re: [android-developers] Re: Sample code for service?

[Kostya Vasilyev]

Petter,

On the XML side, you just need something like this in the manifest:




Where ServiceClassName can be unqualified if it's right in the 
application package, or ".subpackage1.subpackage2.ServiceName" if it's 
nested inside another package - or a fully qualified name in either case.


Make sure that your  is inside 

And by the way, what do you get in the logcat?

[android-developers] Calling WebView.addJavascriptInterface after onPageFinished

[jamesh]

Hi,

I'm trying to add Java objects to a WebView, such that they are
available to Javascript.

I can prove that if I do:

mWebView.addJavascriptInterface(myAvailableAtLoadTimeObject,
"MyJavaObject");
mWebView.load("file:///android_assets/index.html");

I can call methods from Javascript:

MyJavaObject.callableFunction(); // callableFunction is a Java method
on myAvailableAtLoadTimeObject.

or from Java:
mWebView.loadUrl("javascript:MyJavaObject.callableFunction();");

However, if WebViewClient.onPageFinished() has occurred, and then I
try:

mWebView.addJavascriptInterface(myAvailableOnlyLaterObject,
"MyLateJavaObject");
mWebView.loadUrl("javascript:MyLateJavaObject.callableFunction();");

I get an error reported from Javascript:
Uncaught ReferenceError: MyLateJavaObject is not defined

What am I missing, or doing wrong?

Thanks,

James

[android-developers] Re: Does Any one Building Android source code in Mac

[Hari Edo]

A large number of app developers are using Eclipse (or other
tools) on Mac OS X to produce Android packages successfully.

The performance of a machine running Eclipse on Mac OS X will be
about the same as a similar configuration on Linux.  There is no
reason to expect a major shift between these two platforms.

Windows will also have similar performance, but I have heard that
there are some minor USB compatibility complaints or
compatibility with their still-immature 64-bit device layer.

[android-developers] Re: Underclocking to simulate other phones

[Hari Edo]

I think people rely on the software emulator instead.

If you know how to dive into the firmware at that level,
you would know whether you would impact the reliability
and consistent behavior of the device.  I wouldn't trust
the results, myself.

[android-developers] AudioManager.VOLUME_CHANGED_ACTION does not resolve

[A Curtis]

Hello,

I am trying to create a BroadcastReceiver that monitors for Volume
changes. Searching the internet and the GIT repository, it appears
that there is an AudioManager.VOLUME_CHANGED_ACTION. However Eclipse
does not recognize this and will not build the project.

The minSdkVersion is set to 9.

Has this changed?

TIA

I don't know for certain, but I imagine the checkbox background

You could probably get away with just substituting your own drawables

dig into the SDK...

It's not accessible from the official SDK. You can use the string.
Doesn't work on all devices.

[android-developers] Radiogroup adding a radio button in listview

[kiros88]

Hi so basically im trying to have a list in extends ListActivity and
stuff but right now im trying to get a listview of radio buttons which
i guess works but now im trying to apply a radio group for the list.
This is the part im stuck on so basically

once i created my own array adapter i wanted to make in the getView
function every added View(which is radiobutton) to go into the array
adapter add to my radio group

public View getView(int position, View convertView, ViewGroup parent)
{
 // TODO Auto-generated method stub
 //return super.getView(position, convertView, parent);

 LayoutInflater inflater=getLayoutInflater();
 View row=inflater.inflate(R.layout.radio, parent, false);
 //CheckedTextView
label=(CheckedTextView)row.findViewById(R.id.text1);
 RadioButton label =
(RadioButton)row.findViewById(R.id.RadioButton01);
 mRadioGroup.addView(label, position, layoutParams);
 label.setText(zones.get(position));

 return row;

my layout radio.xml just has a

radiogroup
radiobutton inside radiogroup


so the only line that doesnt work is the call to add view in
mRadioGroup

[android-developers] Re: Underclocking to simulate other phones

[neuron]

It's actually very simple.
# adb shell
# su
# cd /sys/devices/system/cpu/cpu0/cpufreq
Your looking for scaling_*. Basically scaling_max_freq (you can use the 
numbers from scaling_available_frequencies). To set a frequency simply write 
to scaling_max_freq.
Example:
# echo 1197000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

[android-developers] savedInstanceState null?

[Chris]

Hi All,

I'm trying to save the state of my app while I shut it down but every
time I bring it back up savedInstanceState is always null..? I
couldn't seem to find much info on calling onSaveInstanceState
properly so here's what I did

onPause ()
{...
  Bundle test = new Bundle();
  this.onSaveInstanceState(test);
}
onSaveInstance(Bundle save)
{
  save.putBoolean("Run", true); // testing
  super.onSaveInstanceState(save);
}

I'd rather use this method than writing to a file or using the saved
preferences..

Can someone help me out?

Thanks,
Chris

Use your debugger to step through the code or use logging to determine what
at that point is null. Then make it so it's not null.

You do not need a scroll view or list view for this. A RadioGroup is a
ViewGroup, which can hold children. You can shove in as many RadioButtons as
you want, and they will all be in that group.

If your app is shut down completely, there is no state to save.

You're not supposed to be calling onSaveInstanceState - the system does this
for you as an indication that you are liable for axing.

Go for it.  Think of it as a learning investment.

You may then decide that you'd like to use some sort of layer on top
of that, to hide some of the details.  But it will help a lot if you
have had some exposure to the underlying stuff.

[android-developers] Re: Calling WebView.addJavascriptInterface after onPageFinished

[jamesh]

Hi, Dan

The Javascript is already in memory (i.e. loaded by Webkit): I can
call functions/methods on that code from Java.

mWebView.loadUrl("file///android_assets/index.html"); // loads a bunch
of javascript.

The onPageFinished method runs, and the page is ready.

This javascript doesn't do anything except initialize itself and wire
up a few listeners/onclick type things.

I can verify that, by invoking a method on an JS object created in
global:

mWebView.loadUrl("javascript:mLoadedEarlier.method();");

It is not doing anything exotic e.g. setInterval() or tight looping.

Once I've done that, I'd like to add my newly minted javascript
interface - the Java object myAvailableOnlyLaterObject:

mWebView.addJavascriptInterface(myAvailableOnlyLaterObject,
"MyLateJavaObject");

Methods will be called on MyLateJavaObject in a click handler, i.e.
some time later. When the appointed time comes for the user to click,
triggering the call, the ReferenceError is reported.

Should I be able to do what I'm asking, and I'm doing it wrong? or am
I holding it wrong?
