[android-developers] How to receive events on MapView using Overlay
Overlay Code:
public class MyLocationOverlay extends
com.google.android.maps.Overlay {
@Override
public boolean onKeyDown(int keyCode,KeyEvent event, MapView view){
System.out.println(==INSIDE onKeyDown
==);
if(keyCode == KeyEvent.KEYCODE_BACK) {
System.out.println(HMM... Calling Your Key Event
\n);
return true;
}
return false;
}
Do I need to call this method explicitly from MapView Acitivity or as
any keydown this will get called ?
Appreciate your input on it.

[android-developers] java.lang.ClassCastException when casting from ParcelableArray

It is illegal in Java to cast an array of a supertype into an array of
a subtype.

[android-developers] **never ever** use Toasts with Activity context
hi, take NotifyWithText api demo as example. add in the begging of onCreate System.gc() and some logs with getInstanceCount() and try to show any Toast, then exit NotifyWithText demo. run it again - you will see getInstanceCount() increases leaking Activities. repeat running demo couple of times. counter still increases. now change context passed to Toast.makeText() by adding .getApplicationContext() - now getInstanceCount() always shows 5. so beware with Toasts - always use app ctx thanks pskink --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Activity Lifecycle
Hi, I did an activity that reads a lot of preferences stuff in its onCreate and configures the app accordingly. Since there is also some multithreading going on in this activity reconfigureing after some preferences change during runtime would be a complicated and error prone task. So I decided to simple launch a new instance of the activity after preferences changed and forget about the old one. I did this using: finish(); startActivity(getIntent()); But now I don't understand the activity lifecycle anymore. The onCreate, onStart and onResume callbacks of the new activity are now called before the onStop and onDestroy callbacks of the old activity I want to replace. Only onPause is called before the new activity starts. May this also happen when not exclicipely restarting the activity. Maybe when changeing the device's orientation? Or is the above finish, startActivity sequence simply not a good idea ;-). Is there no other way how an activity can restart itself?

Correct, this is not designed to allow you to modify it. There are a lot of
serious optimizations (including calls into native code) that preclude it.

Hi Dianne. Thanks for your answer.
I have traced some source codes. I think a new AttributeSet is needed.
First, I have to produce a XML from original AttributeSet with my
modification.
Then put this XML to XmlPullParser, and get new AttributeSet using
Xml.asAttributeSet(...).
But I have to modify obtainStyledAttributes() function (maybe more) in
Resources.Theme Class to deal with generic XML.
It seems a big work..., am I right?

[android-developers] How to release resources when application ends?
Hi, I created an application which is displaying camera preview. When the application terminates I noticed that some processes are still running. Also if I try to run the original camera application it displays an error (obviously due to the active process which belongs to the custom application). Does anyone know how to release all resources when application ends? Thanks!

[android-developers] Re: ListView with different types of View's
Hi You can do the same by extending BaseAdapter and simply override the methods like getCount, getItem , getView etc,, The getView method gets called for each List item.You only need to create and return the list item from here.

[android-developers] Re: Activity Lifecycle
What if you make your activity singleTop and then use onNewIntent() in the same
activity such as
onCreate { configure(); }
onNewIntent { configure() }

Subject: [android-developers] Activity Lifecycle
Hi,
I did an activity that reads a lot of preferences stuff in its
onCreate and configures the app accordingly. Since there is also some
multithreading going on in this activity reconfigureing after some
preferences change during runtime would be a complicated and error
prone task. So I decided to simple launch a new instance of the
activity after preferences changed and forget about the old one. I did
this using:
finish();
startActivity(getIntent());
But now I don't understand the activity lifecycle anymore. The
onCreate, onStart and onResume callbacks of the new activity are now
called before the onStop and onDestroy callbacks of the old activity I
want to replace. Only onPause is called before the new activity
starts.
May this also happen when not exclicipely restarting the activity.
Maybe when changeing the device's orientation?
Or is the above finish, startActivity sequence simply not a good
idea ;-). Is there no other way how an activity can restart itself?
Best regards,
Daniel

[android-developers] A question regarding Activities and Tasks.
I had a question regarding this concept. Suppose i have an application that defines a task. This task has some activities that belong to another Android application. The Dev guide says, that to maintain a uniform user experience, Android will maintain such 'distributed' activities as part of the same 'task' even if they belong to different applications. I refer to it from here: http://developer.android.com/guide/topics/fundamentals.html Some lines later, the Dev guide says and i quote: * * ***Suppose, for instance, that the current task has four activities in its stack — three under the current activity. The user presses the HOME key, goes to the application launcher, and selects a new application (actually, a new task). The current task goes into the background and the root activity for the new task is displayed. The current task goes into the background and the root activity for the new task is displayed. Then, after a short period, the user goes back to the home screen and again selects the previous application (the previous task). That task, with all four activities in the stack, comes forward. When the user presses the BACK key, the screen does not display the activity the user just left (the root activity of the previous task). Rather, the activity on the top of the stack is removed and the previous activity in the same task is displayed.* I think three under the current activity should be four under the same task. I think this paragraph i quote above has nothing to do with activities distributed across applications..and belonging to the same task. This para is maybe talking about two applications, that share a common application launcher and each application has defined its own tasks (stack of activities). The user is simply toggling from one application to another, thus demonstrating that all activities (of a task) move together. However, the three under the current activity phrase is confusing me. Please correct me if I am wrong. Thanks in advance.. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Memory leak in AudioTrack?
Yes, I'm facing the exact same problem. It looks like a bug in
AudioTrack. For me the GREF count seems to increase by 2 for every
creation and use of AudioTrack, and it never goes down. I do not see
this problem when instead creating and using MediaPlayer (and writing
synthesized sound to flash memory), supporting the conclusion that the
problem lies with AudioTrack.
Thanks
On Jun 27, 5:59 pm, Morné Pistorius mpistor...@gmail.com wrote:
Hi all,
If I create and release multiple AudioTrack objects, theGREFcount

This small test code snipped illustrates the problem:
byte[] buffer = readAudioFile( audio.raw );
for ( int n = 0; n 10; ++n )
{
for ( int i = 0; i 100; ++i )
{
Log.v(Info, Track + n + , + i );
AudioTrack newTrack = new AudioTrack
( AudioManager.STREAM_MUSIC, 16000,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT,
buffer.length, AudioTrack.MODE_STATIC );
newTrack.write( buffer, 0, buffer.length );
newTrack.flush();
newTrack.release();
}
Runtime.getRuntime().gc();
}
Even with a forced garbage collection, I end up with the same highGREFcount
at the end of the loop. In my application, I continuously
create AudioTracks from variable lenght buffers. I guess I can try
and use a fixed size pool of AudioTracks each with a buffer large
enough to fit my longest sound, and try and reuse them. Is there a
better/correct way to completely clear resources used by an
AudioTrack?
Any help will be greatly appreciated,
Thanks!

What would I need to change in this code to allow an existing texture

the resource, but when I try this the texture remains unchanged).

[android-developers] Re: A question regarding Activities and Tasks.
I think three under the current activity should be four under the same task. Both is correct: It is a semantic problem of the word under: * four under the same task: There are four activities *within* this task * three under the current activity: There are three activities *below* the current activity. Ok? There are activities A, B, C, D on top of each other. D is the top activity, and three activities (A, B, and C) are below, or under activity D. I think this paragraph i quote above has nothing to do with activities distributed across applications..and belonging to the same task. It can be, because activities A, B, C, and D don't have to be from the same application. A can be OI Notepad list of notes, B can be a OI Notepad note, C can be OI Convert CSV, and D can be OI File manager (so there are activities from 3 different applications). The user started with notepad, wanted to export all notes, and now chooses a location for saving the notes to be exported. If the user goes back to home screen, and launches OI Notepad again, (s)he is presented with OI File manager to select a file location (because that is the activity on top of the OI Notepad stack). Peli www.openintents.org On Jul 3, 12:06 pm, Android Development indodr...@gmail.com wrote: I had a question regarding this concept. Suppose i have an application that defines a task. This task has some activities that belong to another Android application. The Dev guide says, that to maintain a uniform user experience, Android will maintain such 'distributed' activities as part of the same 'task' even if they belong to different applications. I refer to it from here:http://developer.android.com/guide/topics/fundamentals.html Some lines later, the Dev guide says and i quote: * * ***Suppose, for instance, that the current task has four activities in its stack — three under the current activity. The user presses the HOME key, goes to the application launcher, and selects a new application (actually, a new task). The current task goes into the background and the root activity for the new task is displayed. The current task goes into the background and the root activity for the new task is displayed. Then, after a short period, the user goes back to the home screen and again selects the previous application (the previous task). That task, with all four activities in the stack, comes forward. When the user presses the BACK key, the screen does not display the activity the user just left (the root activity of the previous task). Rather, the activity on the top of the stack is removed and the previous activity in the same task is displayed.* I think three under the current activity should be four under the same task. I think this paragraph i quote above has nothing to do with activities distributed across applications..and belonging to the same task. This para is maybe talking about two applications, that share a common application launcher and each application has defined its own tasks (stack of activities). The user is simply toggling from one application to another, thus demonstrating that all activities (of a task) move together. However, the three under the current activity phrase is confusing me. Please correct me if I am wrong. Thanks in advance.. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] ScrollView changs the behavior of the layout even when it's not active.
Hi, My problem is that I would like a button (e.g. Next) to be at the bottom of the screen, unless the content is larger than the screen, in which case it should be scrolled. I can achieve having a layout at the bottom (either trough RelativeView layout_alightToParentBottom=yes, LinearLayout with a View with weight=1 and layout_height=0, or a TableLayout expandRow). However, with each one, once it is wrapped with a ScrollView, the button is brought up next to the previous component, and cannot be glued to the bottom. The ScrollView is not active (needed, components height less than the screen height), yet it affects the components in it. Is that a bug? Is there a way arround it? Any help/suggestion would be much appreciated, as I resorted to having alternative layouts for Landscape, 320x240 and code. Thanks.

[android-developers] Camera preview and sensor orientation values
Hi all, I'm trying to use Camera preview in combination with Orientation sensor. I got a serious problem with the sensor when using the preview: values returned by the sensor are as (1.6893509E-9, -4.0, 0.0) instead of being in degrees (especially the former). I tested that not creating the preview in which will reside the camera output (class Preview extends SurfaceView implements SurfaceHolder.Callback) , the sensor results are in range 0:360, prefectly. Is it possible that opening the camera could generate errors in sensor calculations ? Does anyone has an idea ?

[android-developers] Re: What is the best way to implement dynamic textures in OpenGL ES?
Also you can use glTexSubImage2D() if only a portion of your bitmap is
changing. For these sorts of operations android.opengl.GLUtils will be
*much* more efficient (and simpler) than your current approach of populating
a ByteBuffer since the native helper methods can access the Bitmap pixel
data directly.

However, when ImovetheViewaround with my finger, wouldnt I have to do a requestLayout, since theView changes size when Imoveit? Or could I just set a transform? The other alternative would be to override the draw-method and do most of the work myself. For instance, when the user moves his/her finger, I could get a cache of theViewand just paint it on the Canvas (with some transform). However, how would I do the flinging then, without an Animation? I could use a Scroller/VelocityTracker, but What would drive the repaints? Which is the best way to do this?

[android-developers] Re: Memory leak in AudioTrack?
I should add that I only see the GREF count increasing with the
emulator, not when I run my app on the ADP (connected via USB). On the
ADP I did even after over 300 AudioTrack creations not get the message
that GREF count went above 101 or whatever. I use SDK 1.5 r2 and my
ADP has Cupcake. Curiously, I also found that GREF grows fast when
using some native code from the NDK 1.5 r1 on the SDK 1.5 r2 emulator,
and not when running the same native code on the ADP. Is the emulator
memory management somehow different from Cupcake on ADP?

Log.v(Info, Track + n + , + i );

newTrack.release();
}

}
Even with a forced garbage collection, I end up with the same highGREFcount
at the end of the loop. In my application, I continuously
create AudioTracks from variable lenght buffers. I guess I can try
and use a fixed size pool of AudioTracks each with a buffer large
enough to fit my longest sound, and try and reuse them. Is there a
better/correct way to completely clear resources used by an
AudioTrack?
Any help will be greatly appreciated,

Now check for envelope.bodyIn will give you response from webservice.
This will give you SoapObject. Retrieve response strings from the
SoapObject method.

[android-developers] Re: Question about GENERATING key strokes and DYNAMIC selection of list items.
For the listview part, I found it. I used performItemClick. But for generating keystrokes, nothing seems to work. I tried using onKeyDown and onKeyUp, but it just doesn't do anything (and I need to generate the key strokes from the application). The only thing that seemed to have a result is activity.dispatchKeyEvent. But that seems to only work within the focused view. Like if the view with the focus is a listview, it will jump from listitem to listitem upon generating the Key UP and Key DOWN events. However, if I want to jump from an edittext to another edittext, it will do nothing. As if it stays within the focused view... Anyone knows the correct way to do this? Or a workaround? Thanks. (I'm making something for test automation purposes that is recording and copying what a user is doing on the emulator. Like if a use presses DOWN on his keyboard, the focus will jump from a widget to another. Sadly, I can't find anything that does the same thing programmatically.)

(And WindowManager doesn't provide any function to generate key strokes) For your own activity, you could try manually calling onKeyDown() and onKeyUp(), though I have not tried this. To try to control other applications, you cannot generate keystrokes, AFAIK, probably for security reasons. 2. How do you programmatically select one item from a ListView? Is it possible to do it with the index of the list item (it's position in the list) If by select you mean have it appear with the orange selection highlight, call setSelection() on the ListView. However, this will only work if the activity is not in touch mode -- in touch mode, there is no orange selection highlight except briefly when list items are clicked. -- Mark Murphy (a Commons Guy)http://commonsware.com|http://twitter.com/commonsguy Android Development Wiki:http://wiki.andmob.org --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: IllegalStateException when calling Preference.setDependency()
First of all, sorry for my bad english.
I found the answer in the android sdk source code, the problem is the
following:
When your CheckBoxPreference or an other Preference class call the
setDependency() method, this one will call the following method:
PreferenceManager.findPreference() in the background.
Exactly here is the problem, this works not untill you have called
this method setPreferenceScreen(preferenceScreen) in your
PreferenceActivity.
When you change the call order in your PreferenceActivity to the
following or an analog version, all works fine
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
initPreferenceScreen()
}
private void initPreferenceScreen() {
PreferenceScreen preferenceScreen = getPreferenceManager
().createPreferenceScreen(this);
this.setPreferenceScreen(preferenceScreen);
CheckBoxPreference chbPref1 = new CheckBoxPreference(this);
chbPref1.setTitle(chbPref1);
chbPref1.setKey(preferenceKey1);
preferenceScreen.addPreference(chbPref1);
CheckBoxPreference chbPref2 = new CheckBoxPreference(this);
chbPref2.setTitle(chbPref2);
chbPref2.setKey(preferenceKey2);
preferenceScreen.addPreference(chbPref2);
chbPref2.setDependency(chbPref1.getKey());
}
This snippet is analog to my version, but this one is untested.

[android-developers] Re: Camera in portrait mode
Hi, There is no way of getting the camera preview in portrait mode ( as you probably already know) and its very ( very) slow to rotate the preview image. The only option is to run the app in landscape mode and rotate the view that you want to overlay onto the preview by 90 degrees. To do this override the onDraw() method of the parent view (preferably a linearlayout) and rotate the canvas before calling super.onDraw(). Its going to take a bit of hacking.. Good luck!

[android-developers] AlarmManager nothing happening
I've been modifying things ALL DAY trying to get this to work, please
help.
I have a broadcast receiver that recieves a boot completed signal.
the onReceive method works!... well at least it sends output to the

class never has it's onReceive method called...

FINE-

//This is called when the phone boots
FmiBootup.class
public class FmiBootup extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Log.e(fmi, fmi bootup);
Intent newIntent = new Intent(context, FmiDaemon.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast
(context, 0, newIntent, 0);
AlarmManager alarmManager = (AlarmManager)

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,

[android-developers] Canvas Scaling issues
Hey folks,
A few weeks ago I posted a view I was working on and in that time I
have improved the view a lot, but I've been asked to add a new
features of zooming into the image.
The view is a custom image viewer that allows large images (such as
640x1000) to be loaded, and the user to scroll around using either the
touchscreen or trackball on the device. The code below is reasonably
succesful in that it works at the default scale level of 1.
But with addign zooming, instead of zooming into the 'centre' of the
location the user is looking at, and allowing the user to move around
the whole of the image at this level it instead zooms into the top and
left of the location, and in doing so it starts to cut off the bottom
and right of the image whole, so while zoomed in you cannot go any
ruther right or down in the image, but you can go to the top and left
easily enough.
The best example of what I am trying to achive is the Image viewer in
the camera application.
So my two questions are:
1) Can anyone suggest how I can fix this in the canvas or
2) Is there a better way to do this with an existing feature in the
framework?
I'm probably thinking it's something to do with the modifierValue when
scrolling around that I somehow need to increase this, but trying this
causes my activity to crash.
Code:
public class ZN5ScrollView extends View {
public ZN5ScrollView(Context context, AttributeSet attrs) {
super(context, attrs);
scrollX = 0;
scrollY = 0;
scale = 1.0f;
modifierValue = 50;
ViewPaint = new Paint();
TypedArray a = context.obtainStyledAttributes(attrs,
R.styleable.ZN5ScrollView);
LoadedBitmap =
BitmapFactory.decodeResource(context.getResources(),
a.getResourceId(R.styleable.ZN5ScrollView_src, R.drawable.icon));
IMAGE_WIDTH = LoadedBitmap.getWidth();
IMAGE_HEIGHT = LoadedBitmap.getHeight();
ViewBitmap = Bitmap.createBitmap(LoadedBitmap);
}
protected void onSizeChanged (int w, int h, int oldw, int oldh) {
SCREEN_WIDTH = w;
SCREEN_HEIGHT = h;
if (IMAGE_WIDTH SCREEN_WIDTH) {
IMAGE_WIDTH = SCREEN_WIDTH - scrollX;
}
if (IMAGE_HEIGHT SCREEN_HEIGHT) {
IMAGE_HEIGHT = SCREEN_HEIGHT - scrollY;
}
}
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
canvas.scale(scale, scale);
canvas.drawBitmap(ViewBitmap, 0f, 0f, ViewPaint);
}

switch (zoomType) {
case ZOOM_IN:
if (scale = 1.5f) {
scale = scale + 0.1f;
}
break;

if (scale 1.0f) {
scale = scale -0.1f;
}
break;
}
invalidate();
}

[android-developers] Re: What is the best way to implement dynamic textures in OpenGL ES?
Hi Tom,
Thanks for the suggestion about GLUtils.
I went back found that the TriangleRenderer.java example had been
updated some time ago to use this method which is as you say is *much*
more efficient (faster) simpler than using a ByteBuffer and doing
the color conversions.
( It pays to revisit the examples with new sdk releases ! )

texture for each face dynamic (using Bitmaps created in code). I'm
having trouble understanding how to change the textures on the fly and
I'm hoping someone can point me in the right direction..
This is the code that initially sets a texture:
gl.glBindTexture(GL10.GL_TEXTURE_2D, texBuf.get(num));
Bitmap bmp =
BitmapFactory.decodeResource(context.getResources(),
id);
int pixels[] = new int[TEX_SIZE * TEX_SIZE];
bmp.getPixels(pixels, 0, TEX_SIZE, 0, 0, TEX_SIZE,
TEX_SIZE);
int pix1[] = new int[TEX_SIZE * TEX_SIZE];
for (int i = 0; i TEX_SIZE; i++)
{
for (int j = 0; j TEX_SIZE; j++)
{
//correction of R and B
int pix = pixels[i * TEX_SIZE + j];
int pb = (pix 16) 0xff;
int pr = (pix 16) 0x00ff;
int px1 = (pix 0xff00ff00) | pr | pb;
//correction of rows
pix1[(TEX_SIZE - i - 1) * TEX_SIZE + j] =
px1;
}
}
IntBuffer tbuf = IntBuffer.wrap(pix1);
tbuf.position(0);
gl.glTexImage2D(GL10.GL_TEXTURE_2D, 0, GL10.GL_RGBA,
TEX_SIZE,
TEX_SIZE, 0, GL10.GL_RGBA, GL10.GL_UNSIGNED_BYTE, tbuf);
gl.glTexParameterx(GL10.GL_TEXTURE_2D,
GL10.GL_TEXTURE_MIN_FILTER,
GL10.GL_LINEAR);
gl.glTexParameterx(GL10.GL_TEXTURE_2D,
GL10.GL_TEXTURE_MAG_FILTER,
GL10.GL_LINEAR);
What would I need to change in this code to allow an existing texture
to be replaced (eg. a new Bitmap would be passed in instead of loading
the resource, but when I try this the texture remains unchanged).
Thanks!

[android-developers] targeting broadcasts issue
Guys, I am trying to get the intent android.intent.action.BOOT_COMPLETED sent only to the receiver com.android.mms.transaction.MmsSystemEventReceiver as this triggers the sms notification to be updated and removed if there is no longer any unread sms's. The issue i have is i need to make sure the broadcast is only sent to the class above. If it goes to other receivers the phone could end up in an unknown state or something strange. The code below does not seem to work. Intent intent = new Intent(); intent.setAction(android.intent.action.BOOT_COMPLETED); intent.setClassName(com.android.mms, .transaction.MmsSystemEventReceiver); activity.sendBroadcast(intent); This code does work but since it goes to all receivers i have noticed some errors starting to show up in logs etc. Intent intent = new Intent(); intent.setAction(android.intent.action.BOOT_COMPLETED); activity.sendBroadcast(intent); Chris --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Getting a reference to the option menu.
Sorry, no, the options menu is only created when needed. Your create/prepare callback can however stash away the menu interface it receives for your code to use later.

[android-developers] Re: Question about GENERATING key strokes and DYNAMIC selection of list items.
Test code should use Instrumentation, which allows you to inject your code into the application and control it through the methods there. On Fri, Jul 3, 2009 at 12:59 PM, Mathieu Plourde mat.plou...@gmail.comwrote: For the listview part, I found it. I used performItemClick. But for generating keystrokes, nothing seems to work. I tried using onKeyDown and onKeyUp, but it just doesn't do anything (and I need to generate the key strokes from the application). The only thing that seemed to have a result is activity.dispatchKeyEvent. But that seems to only work within the focused view. Like if the view with the focus is a listview, it will jump from listitem to listitem upon generating the Key UP and Key DOWN events. However, if I want to jump from an edittext to another edittext, it will do nothing. As if it stays within the focused view... Anyone knows the correct way to do this? Or a workaround? Thanks. (I'm making something for test automation purposes that is recording and copying what a user is doing on the emulator. Like if a use presses DOWN on his keyboard, the focus will jump from a widget to another. Sadly, I can't find anything that does the same thing programmatically.)

I found some tutorials where it says to use IWindowManager, but that doesn't exist anymore in 1.5. (And WindowManager doesn't provide any function to generate key strokes) For your own activity, you could try manually calling onKeyDown() and onKeyUp(), though I have not tried this. To try to control other applications, you cannot generate keystrokes, AFAIK, probably for security reasons. 2. How do you programmatically select one item from a ListView? Is it possible to do it with the index of the list item (it's position in the list) If by select you mean have it appear with the orange selection highlight, call setSelection() on the ListView. However, this will only work if the activity is not in touch mode -- in touch mode, there is no orange selection highlight except briefly when list items are clicked. -- Mark Murphy (a Commons Guy)http://commonsware.com| http://twitter.com/commonsguy Android Development Wiki:http://wiki.andmob.org -- Dianne Hackborn Android framework engineer hack...@android.com Note: please don't send private questions to me, as I don't have time to provide private support, and so won't reply to such e-mails.
