[android-developers] Cached Background Bitmaps From Widgets?
So I was just reading a great overview of some of the IO happenings written by Mark Murphy and posted over at http://androidguys.com/?p=5342 and was very intrigued by something... here is the relevant text Next, Romain moved into images, particularly backgrounds for widgets. Backgrounds will always be fitted to the widget, and so Android may have to scale your bitmap to fit the widget – however, scaling at runtime is expensive. It is better, where possible to pre-scale the image and use the scaled one in your layouts, rather than having Android scale it on the fly. You can do this in Java code, via Bitmap#createScaledBitmap(), and setting the widget background from the cached scaled value. From my understanding this is basically saying you can figure out the end size of your widget by reading values cached bitmap object, but I have no idea where to get this object. When I started working with widgets I spent a lot of time trying to figure out the dimensions of the widget but figured it was a lost cause because my understanding was that RemoteView gets inflated after you ever get a chance to work with the specific dimensions... it seems this is still the case but a background bitmap is still cached somewhere? Where can I get a hold of that bitmap object? I tried writing a proof of concept sample for myself, basically th widget layout was a frame layout with a imageView set to fill parent for both width and height... I created a bitmap of a small size (40x40) and set the widgets image view to this bitmap via removoteView.setImageViewBitmap(), i then went back to update the widget 1 minute later and my bitmap object had not been scaled at all... Can anyone help me out with this? Romain maybe? I have a few ideas that require this ability so any help is appreciated --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Cached Background Bitmaps From Widgets?
Hi, A way to do this is to use the onSizeChanged() method. In that method, you know what the exact size of your view is. From there you can easily call Bitmap.createScaledBitmap() to scale your bitmap down.

[android-developers] Re: Hide the virtual keyboard
Indeed, Sujay, thank you!
This will disable (suppress) the soft keyboard:
editText_input_field.setOnTouchListener(otl);
private OnTouchListener otl = new OnTouchListener()
{
public boolean onTouch (View v, MotionEvent event)
{
return true; // the listener has consumed the event
}
};

Hi alex i think u could solve ur problem by using the onTouchListener
rather
since it returns a boolean stating whether u handled the event or not
if u want to show the keyboard return false... else return true...
i'm not very sure that this is wat u want... but u can give it a try

[android-developers] Authorization Idea
Hello all, I would like to apply authorization on my Android application. Once the user logs in I would like to be able to hide or display the actions/activities according to user's role. For instance; If the user in standard role I do not want to let her to start some activities(also hide the activities). Whereas, if the user is in admin role I do want to let her to start some activities that she is authorized to. In addition to separate activity based authorization, I would like to apply UI changes on the same activity according to the user's role. For example; if the user in standard role, she cannot see Reports button on the activity, but if the user in admin role, she can see the Reports button. I can do this via attaching code inside the real code but I want to separate the concept of authorization from the real code. Is there any attribute for methods or activities in Android that let me define authorization on method and activity level. Any help/example would be appreciated, Regards, jojo --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Cached Background Bitmaps From Widgets?
Romain, Thank you very much for the quick response I really appreciate it. This sounds like a very reasonable approach to this problem, but unfortunately I am still confused. I apologize in advance, because I am sure this is a simple concept that I am just not understanding at the moment... Before I go any further I figure I should explain my basic widget update procedure I do it all in a service at the recommendation of jsharkey to avoid ANR dialogs, my service runs somewhat like this - grab an instance of the appWidgetManager - get all of the appWidgetIds for my widget - start loop over these ids -- create a new RemoteView object from the widget Id and my xml Layout which is just a frameLayout and an ImageView -- set the imageView bitmap via RemoteViews.SetImageViewBitmap() -- update the widget via appWidgetManager.updateAppWidget - end loop So usually when I want to get ahold of a view I do a findViewById in an activity, but since I am doing this from a service I didn't think I had access to this method. Where do I access the actual ImageVIew being used so that I can get access to the onSizeChanged method? Or am I thinking about this all wrong? Thanks again for the quick response, I am looking forward to anything else you can help me with on this matter. ---snctln - end loop So I can use teh onSizeChanged() method to see when the bitmap gets scaled... I assume this is for the image View? On May 29, 1:06 am, Romain Guy romain...@google.com wrote: Hi, A way to do this is to use the onSizeChanged() method.

[android-developers] Re: Application.onPause()? Is there a hook like this?
... It's a static reference, ie global to the process. So as activities are started the ref points to the new activity. That said, I agree the right thing to do here isn't obvious. But it's also not obvious to me why you think it's bad to unregister the listener in your apps onDestroy. I am skeptical battery life would be that badly harmed? If GPS keeps running for no reason when the user is on the home screen, users will complain, and rightfully so. GPS is probably the largest battery sucker on Android. Anyway, I guess I'll just stick with my hack, it works well (although I hate that I have to call it in EVERY SINGLE activity the user could potentially exit the app from). Frankly, I already thought about putting together a library with support classes that take care of all those things. I more and more find myself writing boilerplate code for things that really should already be handled by Android... best example is long running operations support (threads spawning from a context), which is very difficult to get right on Android with all the lifecycle states your app can be in, but that's a different story. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: PNG transparency and OpenGL ES
Thank you both for the solution (images must be power of two dimensions) and the additional helpful information! Cheers! -Nate On May 28, 12:56 pm, Anton socialhac...@gmail.com wrote: The ball.png that you reference above is 30x30 pixels. As MrChaz said, you must use power of two sized bitmaps. Otherwise the texImage2D function will not accept your texture. It seems likely that that is what is going on here. Also, this works in the 16 bits per pixel modes as well. You don't need a separate alpha channel in your frame buffer to do alpha compositing, so a simple RGB454 frame buffer works, which is what you get if you use a SimpleEGLConfigChooser (false) to select your pixel format. 16bpp formats are twice as fast when it comes to rendering as 32bpp formats (if your fill rate limited, and if you're rendering a 2D game with sprites then you probably are). Another word of caution, PNG files are supposed to (if you follow the spec) have non-premultiplied alpha channels. But it seems that not many people actually follow the standard, and so you can find PNG files that do it either way. If your PNG files are in fact using non- premultiplied alpha then the glBlendFunction should be (GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA). If they use premultiplied alpha then it should be as MrChaz said (GL10.GL_ONE, GL10.GL_ONE_MINUS_SRC_ALPHA). If you use the first and see dark halos around all of your sprites then you probably have premultiplied alpha PNGs. As a side note, premultiplied alpha is better for a number of reasons. It simplifies a number of compositing operations and treats all of the color and alpha channels in a uniform way. It also allows for super-luminous pixels. -Anton On May 27, 7:00 pm, Nate nathan.sw...@gmail.com wrote: I am rendering this PNG with no transparency just fine:http://n4te.com/temp/test.png However if I try to render this PNG (with transparency) with the exact same code, I just get a white box:http://n4te.com/temp/ball.png I am loading the PNG into a texture like this: Bitmap bitmap = BitmapFactory.decodeStream(input); int[] temp = new int[1]; gl.glGenTextures(1, temp, 0); textureID = temp[0]; gl.glBindTexture(GL10.GL_TEXTURE_2D, textureID); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_NEAREST); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_NEAREST); // GL_LINEAR for quality. gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE); GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bitmap, 0); bitmap.recycle(); I am using this blending: gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA); How is it possible to render a PNG with transparency in OpenGL ES?

[android-developers] Re: PNG transparency and OpenGL ES
I was wandering if you managed to load a RGBA texture without pre- multiplied alpha. I'm working with an assumption that every texture is alpha pre- multiplied, because I was unable to load a RGBA texture without pre- multiplication (on G1). I'd love to know if it's possible or not. Thanks, David On May 28, 9:56 pm, Anton socialhac...@gmail.com wrote: The ball.png that you reference above is 30x30 pixels. As MrChaz said, you must use power of two sized bitmaps. Otherwise the texImage2D function will not accept your texture. It seems likely that that is what is going on here. Also, this works in the 16 bits per pixel modes as well. You don't need a separate alpha channel in your frame buffer to do alpha compositing, so a simple RGB454 frame buffer works, which is what you get if you use a SimpleEGLConfigChooser (false) to select your pixel format. 16bpp formats are twice as fast when it comes to rendering as 32bpp formats (if your fill rate limited, and if you're rendering a 2D game with sprites then you probably are). Another word of caution, PNG files are supposed to (if you follow the spec) have non-premultiplied alpha channels. But it seems that not many people actually follow the standard, and so you can find PNG files that do it either way. If your PNG files are in fact using non- premultiplied alpha then the glBlendFunction should be (GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA). If they use premultiplied alpha then it should be as MrChaz said (GL10.GL_ONE, GL10.GL_ONE_MINUS_SRC_ALPHA). If you use the first and see dark halos around all of your sprites then you probably have premultiplied alpha PNGs. As a side note, premultiplied alpha is better for a number of reasons. It simplifies a number of compositing operations and treats all of the color and alpha channels in a uniform way. It also allows for super-luminous pixels. -Anton On May 27, 7:00 pm, Nate nathan.sw...@gmail.com wrote: I am rendering this PNG with no transparency just fine:http://n4te.com/temp/test.png However if I try to render this PNG (with transparency) with the exact same code, I just get a white box:http://n4te.com/temp/ball.png I am loading the PNG into a texture like this: Bitmap bitmap = BitmapFactory.decodeStream(input); int[] temp = new int[1]; gl.glGenTextures(1, temp, 0); textureID = temp[0]; gl.glBindTexture(GL10.GL_TEXTURE_2D, textureID); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_NEAREST); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_NEAREST); // GL_LINEAR for quality. gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE); GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bitmap, 0); bitmap.recycle(); I am using this blending: gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA); How is it possible to render a PNG with transparency in OpenGL ES?

[android-developers] Re: How to create a simple list of names, with personal image for each row
Thank you Vincent, I've read the link you sent, and it was opening my mind. Now I've solved the problem inheriting from BaseAdapter. There are also some methods to ovverride, and the most important is getView for callback. Then I created a simple class that inherit from LynearLayout, to define the layout of each row. So I solved the problem. The trouble I have right now, is simpler in my opinion. I've decided to delegate the loading of data from network to a thread class, that is started in the main activity with thread.start() passing to it's constructor the inherited BaseAdapter class, making the thread able to modify the list itself. Before launching the new thread the activity starts a ProgressDialog with pd = ProgressDialog.show(...params...); when the thread ends, it requests the stop of the ProgressDialog sending a signal to an handler made for this aim in this way: handler.sendEmptyMessage(0). Now you will ask: where is the problem? Well, the problem is that when the thread ends nothing is displayed on the screen, but the data are there!! The strange thing is that when I use the Hierarchy Viewer, clicking on the Load View Hierarchy button, the screen render the list!!! Can someone help me??

try {
URL aURL = new URL(url);
URLConnection conn = aURL.openConnection();
conn.connect();
InputStream is = conn.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
bm = BitmapFactory.decodeStream(bis);
bis.close();
is.close();
} catch (IOException e) {
e.printStackTrace();
}
return bm;
}

this just load image from my url, may be in cache .
can u please provide any solution to download my files from url and
put them in my apk to use it later

It's easy to make this work though: simply don't call super.onKeyDown()

your activity. Then just call finish() when you do want to end the activity.

The interesting thing here is that when you hit the back button, you
*do* see the AlertDialog for a split second, but then you're back at
the previous screen you were at. Almost as if the system is hellbent
on sending the user back to the previous screen, regardless of what
the developer has constructed around this event.
Anyone else see this behavior? I'm using 1.5r2 here. Any help would
be appreciated - I'm pretty sure I'm using this correctly and that
this is a bug.

[android-developers] Re: What's the best way to handle an task w/progress dialog on orientation change?
This code seems to rely on the fact that your background thread does
not die immediately. If your service is rebound within 30 * 1000
milliseconds, then it all works well.
- This is an unlikely scenario, but what if the re-bind happens more
than 30 seconds later?
- What if the service is stopped entirely and - when your activity (re)
binds - a brand new instance of your service is started? Not very
likely scenario either, but i'm not sure that it could never happen.
Why, instead, don't you keep your service alive by calling startService
()? This makes sure that any subsequent 'unbind' does not stop and
destroy your service.

[android-developers] Parsing Dates in other Locales
I need to parse a date using a flexible date format (like MM/dd/ or dd-MMM), and so far I've always used SimpleDateFormat for that (since unfortunately, android.text.format.Time.parse doesn't support date format strings). This works fine in an US environment, but as soon as I switch to any other locale, MMM translates into the number of the month (i.e. it's 6 instead of Jun). This seems like a problem that's new to Cupcake, although I'm not sure. Is there any way to parse date strings in another locale other than writing my own parser? android.text.format.DateFormat.format is great for converting from date to string, but I can't find anything going the other way around. -Mike --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Hide the virtual keyboard
Actually, there's still a problem.
I only want suppress the soft keyboard from showing up -- because I
have a custom on-screen keypad. Consuming the touch event suppresses
the soft keyboard, but it also holds the focus on the text field,
making it impossible to touch another text field. I have two text
fields, and I want to suppress the keyboard on both, but of course
both fields must still be touchable.
Any idea how to suppress the soft keyboard, but not have the above
mentioned negative side effect?

[android-developers] Android UI guidelines again
Hello All, I know there were a lot of topics like this created earlier, but most of them haven't got any response. I'd like to raise this topic once again and probably ask more concrete questions. I need to create several forms which allow users entering data. Form allows entering text (EditText), numbers (EditText with appropriate input method), boolean fields (CheckBox), choose some options from a list (Spinner) etc. From my previous UI development experience I learned that users expect similar behaviour/loo'n'feel in similar situations. I tried to figure out form designing guidelines looking at built-in Android applications. There were two applications which have forms: Contacts and Calendar. Unfortunately I was unable to define any rules which are common for both applications. From the layout point of view, Contacts uses ListView-like form which looks like a settings form, whereas Calendar uses traditional form with labels and input controls. Choice of an option from a list is implemented differently: - Contacts - Ringtone field - is implemented as a ListPreference widget; - Calendar - Repetition field - is implemented as a TextView (label) + Spinner. Boolean field entry is implemented differently: - Contacts - Incoming calls field - implemented as a CheckBoxPreference; - Calendar - All day flag - implemented as a TextView (label) + CheckBox. So my question is what approach should I use when designing forms for data entry application? Should my forms look like an Event form or like a Contact form? It would be great if somebody from Android team read this message. I see that Android UI evolves, so probably you can give us (developers) some hint about further (planned) UI modifications which help us to design consistent UI.

On May 28, 4:40 pm, Streets Of Boston flyingdutc...@gmail.com wrote:
Is it safe to cache a Handler (in a static variable)?
It should be OK, from my reading of the code. It keeps a reference to
the current threads looper, but that should exist for as long as the
process does anyway.
I *think* you'd code it up like this, although I haven't actually done
it :)
public class MyActivity extends Activity implements Handler.Callback {
static Object sHandlerLock = new Object();
static Handler sHandler;
public void handleMessage(Message msg) { }
public void onCreate() {
synchronized (MyActivity.sHandlerLock) {
sHandler = new Handler(this);
}
}
public void onDestroy() { // Could be onStop as well I think
synchronized (MyActivity.sHandlerLock) {
sHandler = null;
}
if (isFinishing) myThread.interrupt(); // tell the worker thread
to shut down.
}
}
then in your thread:
public void run() {
// ... do some work
synchronized (MyActivity.sHandlerLock) {
if (MyActivity.sHandler != null) MyActivity.sHandler.sendMessage
(whatever);
}
}
You have to lock because otherwise you could test sHandler against
null to see if the activity is still around to receive your status
update, find it's set, then the main thread destroys the activity
resulting in your worker thread crashing when it tries to send a
message to the main thread.
Note the call to interrupt() in onDestroy. You don't want your worker
thread to hang around doing stuff when the user is actually done with
your app. I'm not 100% sure this is correct though - the javadoc for
isFinishing() is kinda vague. Eg I don't know if using the home button
counts as finishing an activity or just task switching away.

[android-developers] Re: What's the best way to handle an task w/progress dialog on orientation change?
Mike: I DO need it to run in the background, that is, while orientation is changing. The service is also really nice because I can do things like submit a score in the background while the user is going from the game back to the game menu. I don't like the static handler idea because it can't have more advanced capabilities like the queue my service has. Basically my service guarantees that the network request will finish and the response will be available to the next registered callback handler. I really like that. I know it's more complicated but my app feels really nice and polished now. Streets of Boston: Each bind is prefaced with a startService. This ensures that the service will be running and will continue to run after the unbind. The service is smart and shuts itself down so this approach works perfectly for me. If a rebind happens 30 seconds later, the service will just start back up in persistent-run-mode like always because startService will have been called. Since the really important stuff always happens within a few seconds of an unbind, the restarting later doesn't matter at all. Also, it will never restart while a user is in an activity because the activity binds onResume and unbinds onPause, so it remains bound the entire time it is visible. I think the way I did it is responsible because the service is always available when needed but doesn't stick around more than 30 seconds longer than the user was last in the app. I'm sure there are other ways but this is coded, well-tested and on the market so I'm not changing it anytime soon :) On May 29, 10:43 am, Mike Hearn mh.in.engl...@gmail.com wrote: Done!

I DO need it to run in the background, that is, while orientation is changing. That's not in the background - the activity manager will keep your process alive during configuration changes anyway, regardless of whether you have a service or not. The only reason to use a service is if you need your process to live on when the activities are not on screen. I don't like the static handler idea because it can't have more advanced capabilities like the queue my service has. Sorry, I don't understand this. You can pass any objects you like through a handler and handlers use the threads message queue anyway.

[android-developers] Re: Android UI guidelines again
Do you mean that in Donut we'll see Calendar application rewritten and its look closer to the current Contacts style? Actually, I thought about it a little bit. It seems to me that Contacts form is more convenient in case when you have many optional/ multiple (I mean you may have from 0 to many values) fields. However, in case when when all (or the most of) fields are mandatory and single (like we have in case with event), those plus/minus buttons look redundant. So I hardly imagine Event form in the current Contact form style.

I'd like to raise this topic once again and probably ask more concrete questions. I need to create several forms which allow users entering data. Form allows entering text (EditText), numbers (EditText with appropriate input method), boolean fields (CheckBox), choose some options from a list (Spinner) etc. From my previous UI development experience I learned that users expect similar behaviour/loo'n'feel in similar situations. I tried to figure out form designing guidelines looking at built-in Android applications. There were two applications which have forms: Contacts and Calendar. Unfortunately I was unable to define any rules which are common for both applications. From the layout point of view, Contacts uses ListView-like form which looks like a settings form, whereas Calendar uses traditional form with labels and input controls. Choice of an option from a list is implemented differently: - Contacts - Ringtone field - is implemented as a ListPreference widget; - Calendar - Repetition field - is implemented as a TextView (label) + Spinner. Boolean field entry is implemented differently: - Contacts - Incoming calls field - implemented as a CheckBoxPreference; - Calendar - All day flag - implemented as a TextView (label) + CheckBox. So my question is what approach should I use when designing forms for data entry application? Should my forms look like an Event form or like a Contact form? It would be great if somebody from Android team read this message. I see that Android UI evolves, so probably you can give us (developers) some hint about further (planned) UI modifications which help us to design consistent UI.

[android-developers] Re: How to find out screen status: active/dark?
I've dug through the documentation but couldn't find a call that would fit: Is there a way to find out the screen status (Active/dark)? You can listen for Intent.ACTION_SCREEN_OFF and ACTION_SCREEN_ON broadcasts. However, I would strongly recommend registering for these dynamically at runtime using Context.registerReceiver(). This ensures that you'll only receive the broadcasts if your Service is already awake, which is what you want. :) -- Jeff Sharkey jshar...@android.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] how to get classes in an apk using DexClassLoader?
I have an apk installed in /data/app. I want to use the class methods
in there. Here is what I tried:
public void test0method(){
DexClassLoader dLoader = new DexClassLoader(/data/app/
com.my.internal.apk,
/data/local/tmp, null,
ClassLoader.getSystemClassLoader());
try {
Class cLoad = dLoader.loadClass
(com.my.internal.SystemProperties);
// got ClassNotFoundException at above line
Method mLoad = cLoad.getMethod(GetString,new Class[]{});
Object obj = cLoad.newInstance();
Object sysProp = cLoad.newInstance();
mLoad.invoke(obj);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
I got ClassNotFoundException. By peeking into the apk, I don't see
class files but classes.dex. I would assume SystemProperties class is
in classes.dex. Why can I load it?
What did I do wrong?
Thanks,
Sherry

[android-developers] Re: OpenGL
I have worked this out!
So for anyone who's interested:
When I removed gl.glEnableClientState(GL10.GL_COLOR_ARRAY); from the
code, it started working on the device, as well as continuing to work
on the emulator. When I put it back in we only get coloured shapes in
the emulator, and not on the device.
Does anyone know why there is this inconsistency? Is it a bug in the
sdk? Or a lack of understanding on my part?

Hi There!
After spending the better half of this day getting my HTC Magic to

coding attempts that appeared to work fine in the emulator doesn't
work as expected on the device. I've narrowed this down to glColorf(r,
g, b, a) not working as expected on the device itself. The provided
OpenGL samples do work though.
So for example, after modifying Cube.java from the samples to the
below code I find that I get the expected grey square on the emulator
but a blank white screen (background fill colour) on the device.
class Cube
{
public Cube()
{
int one = 0x1;
int vertices[] = {
-one, -one,

one, -one,
one, one,

// move them.
//
// Buffers with multi-byte datatypes (e.g., short, int, float)
// must have their byte order set to native order
ByteBuffer vbb = ByteBuffer.allocateDirect(vertices.length*4);
vbb.order(ByteOrder.nativeOrder());
mVertexBuffer = vbb.asIntBuffer();
mVertexBuffer.put(vertices);
mVertexBuffer.position(0);
}
public void draw(GL10 gl)
{
gl.glFrontFace(GL10.GL_CW);
gl.glVertexPointer(2, gl.GL_FIXED, 0, mVertexBuffer);
gl.glColor4f(0.5f, 0.5f, 0.5f, 0.5f);
gl.glDrawArrays(GL10.GL_TRIANGLE_STRIP, 0, 4);
}
private IntBuffer mVertexBuffer;
}
I'm using the latest 1.5 SDK, and my device is the HTC Magic running
firmware version 1.5.
Can anyone explain to me why when switching from colour buffers and
using glDrawElements to glColorf and glDrawArrays, stops shapes from
being coloured in?

create a normal

Are you trying to tell me that it's totally safe to throw stuff in static fields? I've always avoided it because of years of shared space in a JVM in web apps. I know Android uses separate processes for each application but is it safe to say that it will kill all of your static allocations even if you don't clean them up properly? If that's the case, then yes, I probably could have gotten away with using a static gateway instead of a remote service.

That's not in the background - the activity manager will keep your process alive during configuration changes anyway, regardless of whether you have a service or not. The only reason to use a service is if you need your process to live on when the activities are not on screen. I don't like the static handler idea because it can't have more advanced capabilities like the queue my service has. Sorry, I don't understand this. You can pass any objects you like through a handler and handlers use the threads message queue anyway.

[android-developers] Re: Parsing Dates in other Locales
I think this is because many locales are not included in the cupcake release due to size issues.

[android-developers] Screen Brightness
Hi, I read here in several posts thats possible with WindowManager.LayoutParams lp = getWindow().getAttributes(); lp.screenBrightness = 100 / 100.0f; getWindow().setAttributes(lp); to change the screen brightness. ok, but it looks only for the actual activity. (there it works) When I close my activity, the standart system brightness is still the same But how to change the overall brightness, like several tools for 1.5 do? thanks chris --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

Can I use the standard firmware with RfcommSocket or do I need a new image as well ?

What I want to do is connecting the Developer Phone with the Bluetooth receiver on my notebook, sending data and receiving it on the Notebook on a Com-Port maybe with HyperTerminal for Test purpose (In real world a different Hardware is used instead). Bluetooth on the Notebook uses Com4 and 5 for SPP. The Notebook finds the G1 Dev Phone, but as profile for it only A2DP is listed. The G1 Dev Phone finds the Notebook after scanning, Pairing but not connected is stated for this. Any idea how I can get this working ? For now with unhide RfcommSocket ? or do I have to wait for your Bluetooth API ? Do I need a new image for this ? Since we have to present our customer a draft version in aboout 2 weeks there is a little pressure on this for us. So in general can we get that working with the actual possibilities of the SDK and the Dev-Phone or do we have to wait, on a later version of SDK, with your Bluetooth API, or a different Hardware.

[android-developers] SpriteText and coloured surfaces
I've tried to modify the SpriteText sample code, so that it doesn't use textures on the shapes, but instead colour the shapes. For example, modify the sample so that it's a coloured triangle instead of one with the android image. But is doesn't work, and I can't see why. I tried replacing the triangle completey with the Cube object (also from the sample code), as this is a coloured object, but still no luck! What I always end up getting is black objects! When I remove/ comment out the labels and the labelmaker from the code then all of a suddent the objects are coloured as they are supposed to be. Does anyone know how to get coloured objects/surfaces working with the SpriteText sample?

[android-developers] Re: can not find a file in dynamically loaded jar
Thanks for your advice. I created an apk using the same classes and
installed it using adb install to Emulator. Now I tried to use the
following code to access the methods in Class SystemProperties which
is part of newly installed apk. I still got ClassNotFoundException:
public void test0method(){
DexClassLoader dLoader = new DexClassLoader(/data/app/
com.my.internal.apk,
/data/local/tmp, null,
ClassLoader.getSystemClassLoader());
try {
Class cLoad = dLoader.loadClass
(com.my.internal.SystemProperties);
// above line throw ClassNotFoundException
Method mLoad = cLoad.getMethod(GetString,new Class[]{});
Object obj = cLoad.newInstance();
Object sysProp = cLoad.newInstance();
mLoad.invoke(obj);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
I peeked into the apk file and saw classes.dex there. Is there a way I
can dump the content of a dex file and to see if the classes are
there?
Thanks,
Sherry

Two thoughts come to mind:
(1) The Dalvik VM uses its own DEX format, not Java .class files. If
you have a Jar full of classfiles, it's not going to work. The VM
expects to find a single classes.dex in a jar file.
(2) For loading classes from DEX files outside your app's APK you
probably want to use DexClassLoader (introduced in 1.5).
URLClassLoader is not really useful for loading classes.

Do you honestly think insulting Google developers will improve your

Yet, getNeighboringCellInfo() does not work. Any attempt to call it in
an application results in application failure.
File a bug report athttp://b.android.com. I didn't find any issues
referencing that method. If you can attach a project that reproduces the
issue, so much the better.
BTW, the Android 1.5 docs say you need the ACCESS_COARSE_UPDATES
permission -- do you hold that permission? That might be a documentation
bug, in that I cannot find any other reference to that permission, so
you might also try ACCESS_COARSE_LOCATION. None of that would seem to
line up with the stack trace you posted in that one thread, but you
never know...

[android-developers] Re: Sending SMS more than 160 characters
The SMS protocol allows for fragmented SMS delivery, where one long message is splitted into several SMS packets sent to the wire (each one charged separately, of course :-)) This involves setting a fragment bit in the packet, as well as filling an optional header with fragment index+count and other information. The Android GSM stack should be able to re-assemble these properly. When you talk about the other hand, what device is this ?

There is no way to send a single message longer than 160 chars, this is an underlying design featrue of SMS. The system's I've worked with allowed up to 5 SMS' to be stringed together allowing something like 760 characters - but I don't know how it is done apart from the SMS' contains some special codes! /Andrew --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: how to get classes in an apk using DexClassLoader?
Now I used dexdump on /data/app/com.my.internal.apk and saw
SystemProperties class is in the classes.dex file:
Class #9-
Class descriptor : 'Lcom/sprint/internal/SystemProperties;'
Access flags : 0x30001 (PUBLIC VERIFIED OPTIMIZED)
Superclass: 'Ljava/lang/Object;'
Can someone tell me why DexClassLoader.loadClass can not find it?
Thanks.
Sherry

I have an apk installed in /data/app. I want to use the class methods
in there. Here is what I tried:
public void test0method(){
DexClassLoader dLoader = new DexClassLoader(/data/app/
com.my.internal.apk,
/data/local/tmp, null,
ClassLoader.getSystemClassLoader());
try {
Class cLoad = dLoader.loadClass
(com.my.internal.SystemProperties);
// got ClassNotFoundException at above line
Method mLoad = cLoad.getMethod(GetString,new Class[]{});
Object obj = cLoad.newInstance();
Object sysProp = cLoad.newInstance();
mLoad.invoke(obj);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
I got ClassNotFoundException. By peeking into the apk, I don't see
class files but classes.dex. I would assume SystemProperties class is
in classes.dex. Why can I load it?
What did I do wrong?
Thanks,
Sherry

Even if you were to get this working in an emulator, I am uncertain it would work on a device, as you may not be able to access /data/app from your own application. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Warescription: Three Android Books, Plus Updates, $35/Year --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.
