[android-developers] How to find out if device is in sleep mode?

[JP]

I am sure it is buried in the SDK somewhere... but I couldn't find it.
This is relevant to a service running in the background: How can I
find out if the device is in sleep mode?

[android-developers] Re: EMMA Code coverage and JUnit

[Deeps]

Felipe,

Atlast i am half way through in getting the coverage file. But..I dont
see any required output in that file.

I created a sdcard. Then i run my Instrumentation with the following
command,
# am instrument -e coverage true -w com.app.exam.tests/
android.test.InstrumentationTestRunner

First I got error, Is EMMA jar included.

So, i added the amma.jar in the build path. Again I ran the same
command. Then, I found a coverage file , coverage.ec while
navigating thro file explorer of ddms. I pulled it to the desktop and
imported the session to Coverage field in eclipse.

Its unfortunate that I dont see any code coverage but i could see only
the number of instructions.Even though my test cases has run and the
results has displayed, I am getting 0.0% code coverage..

Can u please try this and share ur experience..

 Hi deeps,

 I'm stuck on the point where I need to run the instrumented tests on
 the emulator. I could not find a way yet to make the emulator believe
 that theemma.jar is already installed on it.

 Also, I don't know if there is a way of enablingEMMAinstrumentation
 using the SDK. I have not tried that yet. I'm using theandroidfull
 source, compiling it from scratch. I think I'm close, at least to run
 it on the emulator, but on this past week I was too busy and could not
 investigate more about this issue. I'm planning to put everything I
 know on a blog or something like that, at least to help the other
 developers that are trying to makeEMMAwork onAndroid, since I could
 not find relevant references on this matter from the Google guys.

 I'll send later a step by step of what I made up to now... I'm
 currently at my job, so I don't have much time to write right now.

[android-developers] Re: Find whether any audio is currently playing

[iDeveloper]

Thanks a lot for the answers. I like the idea of a singleton class the  
best. Thanks again.

 Well, seems like you have a couple of issues.

 1) Re-instantiation of your activity that contains the player... if
 you're going to put the mediaplayer in an activity and want to re-
 launch that activity why not use the 'singleTop' or 'singleTask' flags
 in your manifest - (each has a specific use) - they'll let the OS re-
 use an existing Activity rather than creating a new one.

 2) Assuming you've done that you can (a lot more safely) maintain a
 reference to the Activity as suggested earlier, although I'd probably
 tend towards keeping a reference to the player object, maybe even
 wrapping it up as a Singleton to prevent accidental multiple use.  At
 that point you can just call methods on the player (like 'isPlaying
 ()') without having to worry about where it is.

 Just a thought...

 Hi

 I am using a MediaPlayer instance in order to stream audio files

 this activity which plays the audio.

 Now the user might go back to the previous activity (with the list)
 and select another audio file. In this case, I want to stop any
 other audio that is playing and start playing the new audio which
 was selected.

 Is there any way I can know whether an audio file is playing without
 having to hold on to the MediaPlayer object?

 No, and you *should* hold on to the MediaPlayer object, because if
 you don't, it can be garbage collected at any time, at which point
 playback would stop.

Not in the SDK -- you'd need to do all of your own drawing for TextView
(which is basically the thing that draws text wherever there is a widget)
wherever you use it.

[android-developers] Re: How to realize cascading delete in sqlite?

AFAIK although you can set foreign key constraints in SQLite, they
don't actually work.
This is not an android issue, but an unimplemented feature of SQLite.

[android-developers] Can't intercept the OnTouch event of PopupWindow

[Johnny Lee]

Hi all,

I want to intercept the OnTouch event in a PopupWindow, but it failes
everytime. Here is the code snip:

public class Demo extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

// Prepare the popup window
final TextView popupText = new TextView(this);
popupText.setText(Poping up...);
popupText.setBackgroundColor(Color.BLUE);
popupText.setFocusableInTouchMode(true);

final PopupWindow popupWindow = new PopupWindow(this);
popupWindow.setContentView(popupText);
popupWindow.setWidth(100);
popupWindow.setHeight(100);
popupWindow.setBackgroundDrawable(null);
popupWindow.setOutsideTouchable(true);
popupWindow.setTouchInterceptor(new OnTouchListener() {

public boolean onTouch(View v, MotionEvent event) {
Log.d(Demo, popupWindow::onTouch  view:  
+ v + , event:  + event);
return false;
}

});

// Prepare the activity view
final LinearLayout layout = new LinearLayout(this);
layout.setOrientation(LinearLayout.VERTICAL);
layout.setOnTouchListener(new OnTouchListener() {

public boolean onTouch(View v, MotionEvent event) {
Log.d(Demo, layout::onTouch  view:  + v 
+ , event:  + event);
return false;
}

});

final TextView backgroundView = new TextView(this);
backgroundView.setWidth(240);
backgroundView.setHeight(300);
backgroundView.setBackgroundColor(Color.RED);
layout.addView(backgroundView);

final Button button = new Button(this);
button.setWidth(240);
button.setHeight(20);
button.setOnClickListener(new OnClickListener() {

public void onClick(View v) {
popupWindow.showAsDropDown(backgroundView);
}

});
layout.addView(button);

setContentView(layout);
}

When the activity started, I can click the button to show the popup
window correctly. But after that, nothing happens when I touch the
popup window's view. But if I touch any where outside the popup
window, the log
Log.d(Demo, layout::onTouch  view:  + v + , event:  + event);
will work.

It looks like when I touch the view of the popup window, the touch
event has been consumed somewhere?

Do you have any ideas on this? Thanks for your consideration.

Regards,
Johnny

[android-developers] Re: Embedding custom text renderign

[amit mishra]

Hi Dianne

Thanks a lot for the quick reply.

You mean to say that I have to extend the TextView class and override the
OnDraw method. right?

Doing this, i'll loose the actual look and feel of android widgets, which i
don't want.

As I know, Android can recognize the TTF fonts. I have supplied the TTF font
for Hindi but currently its is printing empty boxes for Hindi characters.

I there a way i can provide the TTF font indices to android so that it can
understand the Indian language characters and render it using my fonts.

Thanks in advance.

Amit

[android-developers] calloc probelm in Dalvik

[profect]

Hi all,

I am learning Dalvik by debugging the code. I found some calloc invocations
in allocateAuxStructures() function return NULL. I cound't trace into the
calloc function, so I don't know if memory really runs out or due to other
reasons.

The following is my building environment:
TARGET_PRODUCT=sim
TARGET_BUILD_VARIANT=eng
TARGET_SIMULATOR=true
TARGET_BUILD_TYPE=release
TARGET_ARCH=x86
HOST_ARCH=x86
HOST_OS=linux
HOST_BUILD_TYPE=release
BUILD_ID=
TARGET_DEVBUILD=false
TARGET_DALVIK_COMPILER=gcc

Does anyone have clue in this?

Many thanks.

[android-developers] Re: Can't intercept the OnTouch event of PopupWindow

[Johnny Lee]

Found the problem.

After looking at the source code of PopupWindow, I found the
TouchInteceptor will only be called if the background drawable is not
null. Here is the snip:
private void preparePopup(WindowManager.LayoutParams p) {
if (mBackground != null) {
//...
PopupViewContainer popupViewContainer = new
PopupViewContainer(mContext);
// ...

mPopupView = popupViewContainer;
} else {
mPopupView = mContentView;
}
// ...
}

And the mTouchInterceptor.onTouch will only be called inside the
PopupViewContainer.

So in my code, after I set the background drawable to whatever, (I
used new BitmapDrawable()), the touch event will be intercepted here.

However, I still don't understand why this method only works when
there is a background drawable, here is what's said in doc:

public void setTouchInterceptor (View.OnTouchListener l)

Set a callback for all touch events being dispatched to the popup window.


Regards,
Johnny

                        public void onClick(View v) {
                                popupWindow.showAsDropDown(backgroundView);
                        }

                });
                layout.addView(button);

                setContentView(layout);
        }

 When the activity started, I can click the button to show the popup
 window correctly. But after that, nothing happens when I touch the
 popup window's view. But if I touch any where outside the popup
 window, the log
 Log.d(Demo, layout::onTouch  view:  + v + , event:  + event);
 will work.

 It looks like when I touch the view of the popup window, the touch
 event has been consumed somewhere?

 Do you have any ideas on this? Thanks for your consideration.

 Regards,
 Johnny

[android-developers] Gathering Usage Data - Any ideas welcome!

[Gavin Aiken]

Hi all,

I'm currently working on a demo project and I'm about to try it out with
some users. I'd like to automatically record the way they use the
application, their navigation route, times spent in each section and
duration using the application in general etc. I was wondering if there are
any solutions for this already available and if not how would you go about
achieving such a goal?

My initial thought is that I could augment all of my UI click listeners with
a call to a custom logger class which could write the time and the element,
opening the file for writing in onStart, onResume and closing it in onStop
for the activity.

This doesn't need to be bullet proof, I'm just gathering data to improve the
UI. That being said, I'm sure developing a unified solution would help a lot
of people learn more about how their users interact with their apps and I'm
happy to do the leg work I was just hoping for some advice regarding the
approach to use.

I found this in the google internal code;

UsageStatsServicehttp://www.google.co.in/codesearch/p?hl=en#uX1GffpyOZk/services/java/com/android/server/am/UsageStatsService.javaq=android%20package:git://android.git.kernel.org%20UsageStatsl=17

Which is slightly different to what I need but made me think that perhaps a
background service would be the best option, it could presumably then be
turned on and off and therefore not be used in the deployed version. This
would remove the issue of overhead.

I'm just thinking out loud, feel free to do the same :)

Gav

[android-developers] Re: How to let Android create my activity within the process which the launcher activity lies in?

[Oceanedge]

Sorry, there are three separate applications. One is my Photo Editor
application. The other two applications are the launcher applications,
they emit  android.intent.action.EDIT intent to launch my Photo Editor
application.

The Photo Editor application contains my photo editor activity which
uses a singleton class. And that singleton class instance is used by
the two instance of my photo editor activity due to  other two
applications both emit  android.intent.action.EDIT intent.

What do you mean use the Application context to synchronize access to
the singleton? How should I use it?

Thanks!

[android-developers] image not appearing in the sd card

[Sukitha Udugamasooriya]

Hi all,

Sorry if this is a re-post. I tried to find the solution here but
failed.
I made a small app which downloads an image(jpg) and saves it on the
sd card. It works fine. I could pull the image down in to my computer
and could see it.
But i couldnt see it in the emulator. (not appearing in the gallery)..
Why is that?

private void testDownload(String urlStr) {
URL url = null;
try {
 url = new URL(urlStr);
URLConnection conn = null;
conn = url.openConnection();
conn.connect();
InputStream is = null;
is = conn.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
Bitmap bm = BitmapFactory.decodeStream(bis);
File f = new File(/sdcard/1.jpg);
FileOutputStream fos = null;
fos = new FileOutputStream(f);
bm.compress(Bitmap.CompressFormat.JPEG, 100, fos);
bis.close();
is.close();
} catch (IOException e) {
Log.e(TAG, error6: + e.toString());
}
}
Thanks in advance

[android-developers] Re: How to let Android create my activity within the process which the launcher activity lies in?

[Romain Guy]

The singleton is a perfectly valid pattern with Android, but if you
need to use two instances of your singleton, then the problem is
that you are using a singleton in the first place.

[android-developers] Sending sms via intents launches only the compose window

[Vignesh]

hi,

I am trying to send an sms by using android native messaging application as
follows
Uri smsToUri = Uri.parse(smsto://5556);
Intent i = new Intent(Intent.ACTION_SENDTO,
smsToUri);
i.putExtra(sms_body, This must get sent);
startActivity(i);

All it does is open a compose window with To and Body filled in.What
do I need to do so that the SMS is sent automatically?

Where can I find references to valid putExtras that I MUST do to send an
SMS?  I couldn't find any useful info on Android developer guide - perhaps I
didn't notice them.

Kindly help.

 Does the built-in Maps application work?

 Ifnot, the problem is with your firewall or something else tied to
 networking.

 If it does, then the problem is probably with your API key, or perhaps
 the INTERNET permission.

 It has some code that you may want to use.  Just load up all of your
 frames into an array of bitmaps and then have your draw code draw the
 appropriate bitmap into the correct spot, which is as easy as
 canvas.draw(bitmap, x, y, paint).

 If you need to scale or rotate it, you may want to use a matrix to
 draw and have it position (translate) scale and rotate.

 I just helped someone else doing the same thing.  It's not that hard
 after you've implemented it once.  There is some good discussion in

[android-developers] Re: image not appearing in the sd card

[Saurav Mukherjee]

make sure that the emulator is loaded with the sdcard

 Hi all,

 Sorry if this is a re-post. I tried to find the solution here but

 I made a small app which downloads an image(jpg) and saves it on the
 sd card. It works fine. I could pull the image down in to my computer
 and could see it.
 But i couldnt see it in the emulator. (not appearing in the gallery)..
 Why is that?

 private void testDownload(String urlStr) {
URL url = null;
try {
 url = new URL(urlStr);
URLConnection conn = null;
conn = url.openConnection();
conn.connect();
InputStream is = null;

bm.compress(Bitmap.CompressFormat.JPEG, 100, fos);
bis.close();
is.close();
} catch (IOException e) {
Log.e(TAG, error6: + e.toString());

 }
 Thanks in advance

Yes. It s loaded. I pushed few images from my computer to the emulator
using the command line. I could watch those from the gallery.
In the previous case It downloads images (they are not visible in the
gallery but I could pull them from the command line).

[android-developers] Issue with VideoView for different resolution streams

[vrukesh]

Hi,

We are playing MP4 files on ARM-based target with VGA display (640 x
480).

Playback is done for following resolutions using the sample
applications Music+Camera:

1. stream res.: 640 x 480
Observation: Plays as 640 x 480

2. stream res.: 400 x 240
Observation: Plays as 640 x 384

3. stream res: 320 x 240
Observation: Plays as 320 x 240

I understand that for #1 and #2, aspect ratio is being maintained for
playback and. But, resizing  is being done in onMeasure in
VideoView.java file).

But for #3, stream aspect ratio is already matching display aspect
ratio. And resizing is not done (to 640 x 480).

Exactly why is this resizing not happening ?

Regards,
Vrukesh

[android-developers] Re: Can't change MediaPlayer data source

[Moons]

So what you say is that's it's impossible to have a FileDescriptor
pointing to my raw sound ...

But when you call MediaPlayer.create() it does kinda localize the
sound in the APK.
I'm sure there must be a way to load a sound located in the APK :)

 Correct. An APK file is essentially a ZIP file, and your raw resources exist
 only within the zip file, not as separate files. Therefore, when you get a
 file descriptor for a resource, what you're really getting is a file
 desciptor for the apk, along with the position within the apk, i.e. offset
 and length. This is why openRawResourceFd() returns an AssetFileDescriptor,
 not a FileDescriptor.

[android-developers] Re: ant and eclipse builds don't play nice

from my experience, eclipse never used the build.xml for it's internal

you can omit the android_rules file if you paste the needed targets

then afaik just a few additions are needed (see below)

 Hi,

 I use ant to do release builds, and eclipse to do all my debug builds.
 With the new 1.5 sdk, my build.xml overides the resource-src target in
 order to perform some additional tasks, and it then depends on
 android_rules.resource-src to get the proper toolchain behaviour:

 e.g.
 ...
 setup /
 target name=resource-src depends=my-own-target,
 android_rules.resource-src /
 ...

 This works well for ant, but eclipse doesn't seem to know where
 android_rules comes from (not surprising since it is dynamically
 imported via code), and thus says there is an error in the file. This
 in turn stops the entire android project from building.

 So I need to either somehow get eclipse to parse the build.xml
 properly, or better still, get eclipse to ignore the build.xml
 altogether since build.xml takes no part in the eclipse build.

 Any ideas?

 thanks,
 Craig

[android-developers] blocking click and focus on layout and on all children

[daniel.benedykt]

Hi

I was wondering if its possible to block the onclick events on a
layout and all the children inside the layout.

for example, I have a LinearLayout and inside that I have buttons and
an editText.
At a certain point I don't want the user to click on the buttons or
edit the text.
Is there a way to block that?
Do I have to do it for each view? or I can do it for a Layout?
What is the best way to do this?

Thanks

[android-developers] Re: Progress bar update help

[MrChaz]

You can ask a URLConnection for the content length and then read from
the content stream in chunks.

You can display your progress by setting the max to the content length
and then incrementing the progress by your read chunk size.

[android-developers] Re: How to find out if device is in sleep mode?

[JP]

Well nomenclature...

Here's the scenario: I've got an app that implements the relevant data
processing and backend server connectivity through a Service that I
keep running on a reduced (sleep) activity level when the user puts
the device to sleep (using end button) or when the screen timeout
hits. I can follow this status change, because it triggers calls to
overloaded onStop() and onPause() methods of the app's subclassed
Activity. This way, I control active/reduced (sleep) activity levels
of that Service. Everything's cool and dandy in this scenario.

Enter an AppWidget that's using this Service in a similar fashion,
with functionality implemented in a subclass of AppWidgetProvider.

This changes the game - I have found no way to determine when to set
the Service to the reduced (sleep) activity level from that point.
The app's Activity has long paused, and I keep the Service at active
level, as the widget needs updates from the Service similar to what
the Activity needs when in front. With the AppWidget on the home
screen, I want, and should (re: battery life), drop the Service's
activity level when the device enters sleep mode. The most elegant way
to handle this would be to detect whether the device sleeps (or, on
second thought, better actually, whether the display is dark) right
inside the Service. This way, as a side product, I can also drop
following the device status in the overloaded onStop(), onPause(),
onStart() and onResume() methods.

1. You have created a PhoneStateListener and then have done nothing with
it. Please look at TelephonyManager#listen() in the documentation.

2. You are not cleaning up the MediaPlayer objects you are creating, which
might be bad.

3. You are not unregistering your PhoneStateListener when your activity
closes (e.g., in onDestroy()).

There may be other issues -- those three come to mind for me.

[android-developers] Surface flinger - overlay

[Arun]

Hi,
  I am implementing a custom MIO which makes use of Overlay
interface in ISurface.cpp. In android_surface_output.cpp file we
changed the initCheck function to call the createoverlay interface

mSurface-createOverlay(displayWidth, displayHeight,videoFormat);

but the function returns NULL. Here fuction createOverlay calls the
onTransact function in ISurface.cpp and from there it goes to the
overlay source object creation in Layerbuffer.cpp which calls the
overlay object creation.

My overlay object is created sucessfully..but the problem is after
returning to the createOverlay in Isurface.cpp the next function is
writetoParcel.Here writing is happening without any issue.But while
reading using the function readfromParcel iam getting failure message
in readobject function.

Is there any problem with custom MIO implementation?

Thanks in advance

Well, yes and no. Read again what I said.

But when you call MediaPlayer.create() it does kinda localize the
 sound in the APK.
 I'm sure there must be a way to load a sound located in the APK :)


Of course there is. You've even used one of those methods already:
MediaPlayer.create(int resourceID).
To do that with a filedescriptor instead of a resource ID, you'd use:
MediaPlayer.setDataSource(FileDescriptor file_descriptor_of_apk_file, long
offset_within_apk_file, long length_of_data_within_apk_file).
All three arguments can be obtained from the AssetFileDescriptor object that
you get from openRawResourceFd()

[android-developers] Re: how do i kill an android application

[Mariano Kamp]

In short: Don't worry.

A bit longer: Android manages the apps' states.
The user keeps on doing things, launching tasks, firing intents etc. and
when Android OS doesn't have enough memory left it kills of apps that are in
memory, but don't seem that important anymore, e.g. because the UI is not
visible anymore as the user navigated back to the home screen or to another
app/activity. If you app is needed again Android OS will resurrect you
app/activity. Just implement the proper call backs
(onCreate/onResume/onPause etc.) and your good to go.

[android-developers] Re: Create Bitmap from BitmapDrawable?

:) Hi Tom,

indeed, look good, but it looks it does not include my manipulations I
did on the Drawable

Bitmap BitmapOrg = BitmapFactory.decodeResource
(resources,R.drawable.mydaysminipic_td);//its a green icon on a
transparent background
BitmapDrawable bmd = new BitmapDrawable(BitmapOrg); // to
BitmapDrawable
bmd.setColorFilter(0x00ff,Mode.SRC_ATOP);  //manipulating the
Bitmapdrawable to make all nontransparent pixels Blue
//when i just test the Drawable its fine !!

updateViews.setImageViewBitmap(draws2[i + 10], bmd.getBitmap());
But bmd.getBitmap() just give me original (maybe underlying Bitmap)..
but how to get the DrawAble I created?

[android-developers] bindService() from multiple activities

[Al]

Hi all, I have a quick query about bindService(). My main activity
first starts and binds to the service. Other activities are then
launched from the main activity. The child activities all bind to the
same service, but it seems my service's onBind() is only called once.

The application runs fine, but I thought the correct behaviour is that
onBind gets called everytime an activity calls bindService()?

[android-developers] Re: how do i kill an android application

[blindfold]

Yes, you can use System.exit(0) in your own app. I applied this myself
for some time when I could not track down a bug in my app that ate
memory by creating new threads without killing old ones upon app
restart, and System.exit(0) then provided a temporary workaround to
start fresh until I later found out that my problems indeed came from
those threads piling up - visible in DDMS once you look for them, but
I thought at the time that I was having memory problems due to my
bitmaps or array variables still floating around after restart.

But I haven't found how to do that.

I can create an empty BitmapDrawable(), then setBounds(Rect

but How can I load the image after that, inside this bounds?

Anyway, I think that setting Bounds do not limit what fragment from
the original image will be load in memory, only what will be draw.

method is never called...

[android-developers] ImageMatrix has no effect when ImageView is in matrix scaling mode

[Max Salley]

I have an extension to ImageView that I would like to draw by manually
altering the ImageMatrix.  When I set the View's scaling type to
matrix however, changing the matrix has no effect on the image.  If I
put it into a different mode, say center, changing the matrix does
change the display, but in some the matrix gets reset to the proper
value for center rather than what I want it to be, so I can't really
use a different mode as a workaround.  Here's the code that changes
the matrix (the view implements OnGestureListener

public boolean onDown(MotionEvent e) {
Log.v(TAG, onDown);

Matrix m = getImageMatrix();
Log.v(TAG, Initial matrix:  + m.toString());

m.postScale(2.0f, 2.0f);
setImageMatrix(m);
Log.v(TAG, New matrix:  + getImageMatrix().toString());

invalidate();

return true;
}

Here is what the log shows

V/Gesture-Enabled Image View( 3110): onDown
V/Gesture-Enabled Image View( 3110): Initial matrix: Matrix{[1.0, 0.0,
0.0][0.0, 1.0, 0.0][0.0, 0.0, 1.0]}
V/Gesture-Enabled Image View( 3110): New matrix: Matrix{[2.0, 0.0, 0.0]
[0.0, 2.0, 0.0][0.0, 0.0, 1.0]}
V/Gesture-Enabled Image View( 3110): onSingleTapUp

The display remains unchanged, though.  How can I get the image to
change with the matrix?

[android-developers] Re: onKeyDown doesn't capture event

[Mark Murphy]

 I have a proble with onKeyDown:
 my activity consists in a simple textView (as header) and a ListView
 below it, I need to go back to the previous screen when the user
 presses the back button.

That should happen automatically, without implementing onKeyDown().

 Thus, I implemented the onKeyDown method.

Where? On the activity? On a subclass of one of the widgets?

 Everything works fine if the
 list contains some elements, but when the list is empty the onKeyDown
 method is never called...

I would just get rid of it and allow Android to handle the back button,
since Android's default behavior seems to be what you want.

[android-developers] Re: Widget bug, is there a work around?

[Tom Gibara]

How does this address the OP's issue? The invisible widget will still
continue to receive updates and consume resources.
Tom.

2009/5/26 AndroidApp zl25dre...@gmail.com


 This is what I am doing, it doesnt fix the problem but it mitigates
 it:

 Dont bother having a configure activity, remove that from the widget
 xml config file. This always add the widget to the screen without
 configuring it. Then onUpdate in your widget, start a service to
 perform update, in your service before you push out update, first
 check whether the widget you are updating has been initialized, if it
 has not been initialized, start the configure activity on the service

Dear google guys,
 
the widget framework (or the Home app) has a pretty bad bug:

- *CHANGE ORIENTATION*

widget
 
the widget will not show up, did some debugging it looks like the
widget is added to the widget service but it's just not shown on the
Home screen, so if a widget has a config activity and the user
 happens
to change orientation during widget config time (very common if
 widget
has text boxes), the widget will become a garbage that just take up
resources until user uninstall the widget app. even worse, if the
widget does heavy background service to update, it will be wasting
time updating a widget that is not visible
 
Does anyone know a work around?

[android-developers] Re: Create Bitmap from BitmapDrawable?

[Tom Gibara]

The ColorFilter you apply to a BitmapDrawable isn't applied directly to the
Bitmap, it's applied to the Paint used to render the Bitmap. To get an
equivalent Bitmap:
  * Create a new Bitmap of the same width, height and Config
  * Create a Canvas over the new Bitmap
  * Call BitmapDrawable.draw(Canvas)

The new Bitmap should now contain what you want.

Tom

2009/5/26 guruk ilovesi...@gmail.com


 :) Hi Tom,

 indeed, look good, but it looks it does not include my manipulations I
 did on the Drawable

 Bitmap BitmapOrg = BitmapFactory.decodeResource
 (resources,R.drawable.mydaysminipic_td);//its a green icon on a
 transparent background
 BitmapDrawable bmd = new BitmapDrawable(BitmapOrg); // to
 BitmapDrawable
 bmd.setColorFilter(0x00ff,Mode.SRC_ATOP);  //manipulating the
 Bitmapdrawable to make all nontransparent pixels Blue
 //when i just test the Drawable its fine !!

 updateViews.setImageViewBitmap(draws2[i + 10], bmd.getBitmap());
 But bmd.getBitmap() just give me original (maybe underlying Bitmap)..
 but how to get the DrawAble I created?

 many Thanks...

 Greets
 Chris

[android-developers] Triangle strip problems

[Sundog]

Hello, I'm having trouble with something that should be
straightforward and was hoping someone who has been down this road
could help.

I'm simply drawing a 32 by 32 (float) vertex (3d but flat for testing)
square surface by drawing it as 31 linked triangle strips. I'm linking
them by four degenerate triangles at the end of each strip as follows:
repeat last vertex of this row, first vertex of next row, repeat first
vertex of next row, second vertex of next row.  My examination of the
numbers I'm feeding OpenGL don't reveal anything amiss.

What happens is that some triangles don't draw; I am assuming they are
invalid for some reason I can't see. This happens at any resolution 8
x 8 or larger, with a different pattern for each size. Apparently
something is interfering with the drawing of certain triangles.

I MIGHT have missed something poring over these numbers, but I don't
think so. Does anyone have a clue? Could it be caused by using floats
instead of fixed point?

You see the tasks of the most recent activities. If you select one and the
attached app and process is still running it will be brought in the
foreground, if not it will be started first and then brought into the
foreground.
That's what I meant with Don't worry about it. Android OS manages that.

[android-developers] Re: Progress bar update help

[Keith Wiley]

Would your suggestion actually work?  I'm not convinced it's that
simple.  You still wouldn't see the progress bar appear on the screen,
much less update smoothly on demand, because you would be constantly
tying up the UI thread.  I think you need to create the progress bar
on the main UI thread, set up its max, init its val to 0, then make a
separate thread that reads the file and occasionally sets the progress
bar's progress to a new val (you can do that from a nonUI thread
apparently, works for me).

On May 26, 5:48 am, MrChaz mrchazmob...@googlemail.com wrote:

[android-developers] Re: detecting idle, off hook and ringing

[PI9]

I add :

 @Override
  public void onResume() {
   super.onResume();

 telephone.listen  (psl,
android.telephony.PhoneStateListener.LISTEN_SERVICE_STATE);
  }

  @Override
  public void onDestroy() {
  telephone.listen  (psl,
android.telephony.PhoneStateListener.LISTEN_NONE);
  }

but still ...
i tried everything and compared parts of my program with solutions i
found on this group and i don't understand why this doesn't work !!!

  Please someone can take a look at it and try to explain to ma what's
  wrong ?

 1. You have created a PhoneStateListener and then have done nothing with
 it. Please look at TelephonyManager#listen() in the documentation.

 2. You are not cleaning up the MediaPlayer objects you are creating, which
 might be bad.

 3. You are not unregistering your PhoneStateListener when your activity
 closes (e.g., in onDestroy()).

 There may be other issues -- those three come to mind for me.

[android-developers] Re: How to realize cascading delete in sqlite?

[Marco Nelissen]

I've never used cascading deletes myself, but I have used triggers, and they
work.

[android-developers] Drawable cannot draw into Canvas

[Jay]

I want to load an icon from resource and draw over it. But I cannot
get it into a canvas. Can anyone please help me with the code below.
If I uncomment c.drawColor(), I get blue color as expected. So the
problem is on icon.draw().

Drawable icon = getResources().getDrawable(R.drawable.icon2);
Bitmap bitmap = Bitmap.createBitmap(icon.getIntrinsicWidth(),
icon.getIntrinsicHeight(),
Bitmap.Config.ARGB_);
Canvas c = new Canvas(bitmap);
icon.draw(c);
//c.drawColor(Color.BLUE);

ImageView iv = (ImageView)findViewById(R.id.icon);
iv.setImageBitmap(bitmap);


Thanks,
Jay

[android-developers] Re: Create Bitmap from BitmapDrawable?

[guruk]

Hi Tom, thanks for your help

do you mean something like that: (till now i did not worked)

Bitmap ob = BitmapFactory.decodeResource
(resources,R.drawable.mydaysminipic_td);
Bitmap obm = 
Bitmap.createScaledBitmap(ob, 18, 18,false);
Canvas canvas = new Canvas(obm);
BitmapDrawable bmd = new 
BitmapDrawable(canvas);

bmd.setColorFilter(0xff00,Mode.SRC_ATOP);
bmd.draw(canvas);
Bitmap newbit;
newbit=bmd.getBitmap();

Really I came crazy with that. Finaly I just need the Solution for:

I have a Drawable and I like that all set pixels in it get another
Color and
finaly to update my widget ... for that I have to options:

updateViews.setImageViewBitmap(draws2[i + 10], newbit);  //thats what
I try now with above code

or i make it simple:  (but i miss a link)
--
Drawable dx = resources.getDrawable(R.drawable.mydaysminipic_ov);
dx.setColorFilter(0xff00ff00, Mode.SRC_ATOP);
updateViews.setImageViewResource(draws2[i + 10],
R.drawable.mydaysminipic_pe);
--
but that does not work, because WHAT is the ID (int) of my created
dx??

Any Ideas to solve that. would be really great

Thanks
Chris
