Nevertheless, what I was looking for is view something else. To clarify my requirements a little more: there is just a fixed size View which is larger than the screen and you need to scroll that and its child views in both directions.

[android-developers] Architecture dilema
Hello! This may sound a little silly. Let's say I want to build a game with a menu, an options screen, a form screen (for the user to insert some data) and the game screen. The usual approach would be to have an activity for each case (correct me if I'm wrong). What if I do another thing... and code four views for each case and swap them using setContentView() in the same activity? Suppose that I'll override the onSaveInstanceState() to save the state of the views in all the four cases. What is the disadvantage in this approach besides having a huge activity that I'm sure it gets closed every time the system is low in memory? I haven't tested it yet, but I didn't find anything in the docs that could stop this approach to work. The reasons for avoiding the usual implementation is that I need to convert an application from J2ME and having multiple activities raises some difficulties in the porting process.

[android-developers] Re: HVGA T-Mobile G1/G2 vs. iPhone
Current Android phones have 16 bit displays, though that is just a hardware detail, and not related to Android itself. I am pretty sure iPhones also have 16 bit displays, though the new 3GS may have a 24 bit display. (Actually often they will claim an 18 bit display... which almost always means that the display itself is 18 bit, but the frame buffer is still 16 bit, and they wire the low bit of green to the extra low bit of red and blue in the display.)

[android-developers] Re: How to find information about BatteryManager and the way BroadcastReceiver works?
So there is no way to learn which constants are available? (except finding some codes on the Internet...) I am quite disappointed ;-) Thanks for your answer, D. On Aug 19, 6:40 pm, Mark Murphy mmur...@commonsware.com wrote: DaminouU wrote: Hi, I was wondering how to use the BatteryManager's constants when I find this link : http://twisty.googlecode.com/svn-history/r26/trunk/twisty/src/com/goo... There you can find a method called monitorBatteryState. In this one I saw those lines : int rawlevel = intent.getIntExtra(level, -1); int scale = intent.getIntExtra(scale, -1); int status = intent.getIntExtra(status, -1); int health = intent.getIntExtra(health, -1); ... I am a newbie on Android so I read Intent and BroadcastReceiver to understand what it is and where I can find a list with that data (level, status, ...) but I didn't find anything. They are undocumented, unfortunately. On the other hand, if you simply dump all of the extras out of one of those Intents, you will find that most are self-explanatory, or tie into constants defined on BatteryManager. Note that level is in terms of scale (e.g., if scale is 100, level will be 0-100 indicating an integer percentage of battery life remaining). I think I understand that those values are modified by the battery and that my broadcastReceiver gets these changes. Is it correct?

[android-developers] ActivityGroup: get reference of the LocalActivityManager
hey guys,
i have a tab with an activitygroup as the intent of tab1.
my code of the activity(group):
public class TabActivityGroup extends ActivityGroup{
protected static LocalActivityManager mLocalActivityManager;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
replaceContentView(new Intent(this, dosomething.class));
}
public void replaceContentView(Intent newIntent) {
View view = getLocalActivityManager().startActivity(id,
newIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
.getDecorView();
this.setContentView(view);
}
}
my task:
i do something in the dosomething.class which is loaded by default
in the ActivityGroup an after a click on a button, the activity inside
the tab1 should change to dosomethingselse.class.
this is of course the wrong way to start the activity inside the tab1
('cause it overlay the tabactivity completly):
//Intent i = new Intent(this, dosomethingselse.class);
//startActivity(i);
so how can i get the reference of the LocalActivityManager inside
the dosomething.class to start the other acitivty
dosomethingselse.class from an method? or is there any way, how to
handle this better?
many thanks in advance!
best regards,
ludwig

[android-developers] Re: Horizontal Scrolling with fling gesture - ebook reader
I've implemented this on a picture slideshow app that I will publish
soon.
The principle is to use a GestureDetector which is set as the manager
of touch events of your Activity. Your activity can then implement an
OnGestureListener to react to specific gestures.
Here is some code extracted from my app :
import android.view.GestureDetector.OnGestureListener;
private class SlideShow implements OnGestureListener {
private GestureDetector mGestureScanner;
@Override
protected void onCreate(Bundle savedInstanceState) {
// [...]
mGestureScanner = new GestureDetector(this);
// [...]
}
@Override
public boolean onTouchEvent(MotionEvent me) {
return mGestureScanner.onTouchEvent(me);
}
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float
velocityX,
float velocityY) {
if (velocityX 0) {
goForward();
return true;
} else if (velocityX 0) {
goBack();
return true;
}
return false;
}
}
For the sliding effect, I have used a ViewFlipper and 3 ImageViews.
I defined in the apps resources 4 animations :
Going forward :
- translation from center to left : make the current page go away
(out)
- translation from right to center : make the next page come (in)
Going backward
- translation from center to right : make the current page go away
(out)
- translation from left to center : make the previous page come (in)
Depending on the direction of the fling, I set both in and out
animations of the ViewFlipper to the corresponding couple of forward
or backward animations.
I use 3 ImageViews so that my previous and next page can be preloaded
before the user decides to fling, otherwise the time between fling and
animation can be quite long if the next/previous view is long to
initialise.
Once the animation is finished, I rotate the role of each view and
preload the new next or previous image in the view that is now 2 pages
away from the current.
I hope this helps.

So my application has a large amount of textual data. Up until this

the Ebook reader from Alkido that is available on the store which uses
a horizontal fling gesture to flip the pages. Does anyone have any
experience doing something like this? I've done it a number of ways,
but none seem to be very smooth or efficient. Thanks in advance.

[android-developers] Re: How to avoid Touch Event
Thanks!
I tried to put a transparent layout onto the top and make it cover the full
screen.OnTouchEvent of this layout had been overrided and it actually
catched all OnTouch event;
but the problem is that some Views under this layout can not catch OnKeyDown
after OnTouchEvent happend onto the top layout. It looks that though
OnTouchevent is consumed by the top view but Focus still changed?
My doubt is that all OnTouchevents are consumed by the toplayout , why some
Views under this layout looks still be effected by this OnTouchevent? should
framework do some elsejob to process this Touch Event?
Thanks!

In fact, I have tried overriding OnTouch(), and I tried two cases to
overriding OnTouch():
1 OnTouch(){
return false;
}
In this case, OnTouch event will be passed to the next view in Viewgroup.
It is not I want.
2 OnTouch(){
return ture;
}
In this case, OnTouch event will not be passed to other view. But it will
cause this iew's OnKeyDown() not called even key pressed. I think it is
caused by Focus changed.
Because there are many views in my application and app will manage all
focus by it's own way . It means when TouchEvent happens, the Focus will be
distored. App has to revert the Focus to the previous state before
TouchEvent happens.
For my application, it is special and all operation should be done by Key
not by Touch.
So I have to ask for Group to find the way to avoid any OnTouch event.

What I want is only to disable Touch event because my application need

It seems that onActivityResult method is never called, what am I
missing here? Camera activity is closed and first activity is shown
again but onActivityResult is not called.
It works perfectly fine (onActivityResult is called and toast is
displayed) if do following on cameraintent:
@Override
public void onPictureTaken(byte[]data, Camera camera) {
try {
//IntentresultIntent = newIntent();
//resultIntent.putExtra(cameraData,data);
setResult(Activity.RESULT_OK);
finish();
} catch (Exception ex) {
setResult(Activity.RESULT_CANCELED);
finish();
}
With code above Activity.RESULT_OK (-1) is returned to
onActivityResult method.
I'm testing with HTC Hero.

In any activity, you can get the reference for your application

[android-developers] Re: Got InflateException in my MapView xml file
I was suffering the exact problem and finally found 'the' cause.
In onCreate(Bundle arg0) I was calling super.onCreate(arg0) after the
setContentView(R.layout.location_select_on_map_view) !
Once I corrected it the MapView was displayed correctly :-)
E.g.
@Override
protected void onCreate(Bundle arg0) {
super.onCreate(arg0);
setContentView(R.layout.location_select_on_map_view);
}

[android-developers] Re: Activity Lifecycle Cause Memory Leaking
I experienced similar problems. Depending on how you navigate back to your Activity, Android does not know that it should reuse the existing instance and creates a new one. You can fix this easily with the activities launch mode, which you set in the AndroidManifest.xml. Setting it to singleInstance will ensure that there is only ever one instance. Depending on your app this might have other disadvantages, so you should check this part of the documentation: http://developer.android.com/guide/topics/fundamentals.html#acttask On 7 Aug., 07:23, efan e...@efansoftware.com wrote: Tested on both 1.5-R2 and R3, same result.

This behavour causes memory leaking for the big image (size 960*1920). After 6+ times away and back to activity, the system runs out of memory and has tokillthe process. One workaround is to initialize the big image in onResume() and recycle in onPause(), but that's not so good reuse.

You can also use full screen non-transparent dialogs. They look like activities, but are simpler to handle. For example for Settings screen of a game I would (and in fact, do) go with dialogs.

Let's say I want to build a game with a menu, an options screen, a form screen (for the user to insert some data) and the game screen.

What if I do another thing... and code four views for each case and swap them using setContentView() in the same activity? Suppose that I'll override the onSaveInstanceState() to save the state of the views in all the four cases. What is the disadvantage in this approach besides having a huge activity that I'm sure it gets closed every time the system is low in memory? I haven't tested it yet, but I didn't find anything in the docs that could stop this approach to work. The reasons for avoiding the usual implementation is that I need to convert an application from J2ME and having multiple activities raises some difficulties in the porting process.

[android-developers] How can I find my GPS location with GPS sensor
Hi,
I am currently working with a HTC G1 and I am trying to retrieve my
GPS position. But I can not understand very well the documentation. I
wrote those lines, but they didn't work.
LocationManager mgr = (LocationManager) this.getSystemService
(Context.LOCATION_SERVICE);
GPSSensor gps = new GPSSensor(mgr);
String provider = ;
provider = mgr.getBestProvider(new Criteria(), true);
try {
Location loc = mgr.getLastKnownLocation(provider);
tv.append( Location: + loc.toString() +
\n);
}
catch(Exception e) {
tv.append(provider == null);
}
[tv is a TextView object]
It already write provider == null so I guess that
mgr.getBestProvider(new Criteria(), true); returns null.
Could you explain to me what I need to do?
Thanks.

[android-developers] Re: out of memory error getWallpaper
I'm seeing the same out of memory problem. It's consistent on my G1 in a few tries. Basically I used the built-in intent to get the photo on my sdcard, and set it as the app's background: Drawable d = Drawable.createFromPath(filename); mainBg.setBackgroundDrawable(d); The filename is what passed back from the photo picker in onActivityResult(). Doing this a few times will cause out of memory exception, reproducible 100% of the time. If the VM is to *eventually* free up the bitmap object memory, I suspect it's not doing its job well. I will give the recyle() a try now, and see if there's any improvement. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Using sensors and orientation - lat/lon point to screen coordinates
Hi,
I want to find the screen coordinates (X,Y) where a point represented
by a latitude/longitude value would appear on the screen if you
pointed your phone at it (much in the same way as Wikitude does).
Here is my code from my onSensorChanged() method:
public void onSensorChanged(SensorEvent event) {
Sensor sensor = event.sensor;
int type = sensor.getType();
switch (type) {
case Sensor.TYPE_MAGNETIC_FIELD:
mags = event.values.clone();
isReady = true;
break;
case Sensor.TYPE_ACCELEROMETER:
accels = event.values.clone();
break;
case Sensor.TYPE_ORIENTATION:
orients = event.values.clone();
break;
}
if (mags != null accels != null isReady) {
isReady = false;
SensorManager.getRotationMatrix(R, I, accels, mags);
SensorManager.remapCoordinateSystem(R,
SensorManager.AXIS_X, SensorManager.AXIS_Z, outR);
SensorManager.getOrientation(outR, values);
azimuth = convert.radToDeg(values[0]);
pitch= convert.radToDeg(values[1]);
roll = convert.radToDeg(values[2]);
}
}
I convert the points I wish to project from their lat/lon spherical
coordinates to Cartesian coordinates and perform a perspective
projection using the roll, pitch and azimuth values returned by the
sensor, however, I can never seem to get accurate screen coordinates
of the points.
The matrices for roll, pitch and azimuth I use are:
// pan
double[][] azimuthMat = {
{Math.cos(azimuthValue), -Math.sin(azimuthValue), 0},
{Math.sin(azimuthValue), Math.cos(azimuthValue), 0},
{0, 0, 1},
};
// tilt
double[][] pitchMat = {
{Math.cos(pitchValue), 0, Math.sin(pitchValue)},
{0, 1, 0},
{-Math.sin(pitchValue), 0, Math.cos(pitchValue)},
};
// roll
double[][] rollMat = {
{1, 0, 0},
{0, Math.cos(rollValue), -Math.sin(rollValue)},
{0, Math.sin(rollValue), Math.cos(rollValue)},
};
I also perform the necessary translation of the projection cener and
the point to project e.g:
// Translate the point
subtract(pointToProject, projectionCenter);
... where 'pointToProject' and 'projectionCenter' are double arrays
holding the Cartesian coordinates of each location (i.e. camera lat/
lon and the point to project lat/lon)
I realise this is quite a complicated question to ask and I haven't
provided all my projection code etc, however if someone feels they can
help me out and may know how to achieve what i'm after - i'll post the
whole code.
Thanks

Step #1: Get the source for the APK. If you can't do that, you cannot
modify the APK's behavior.
Step #2: Modify the manifest to add android:screenOrientation attributes
to each activity element for which you wish to change the rotation rules:

[android-developers] Re: ListView onListItemClick to Create a Context Menu?
Actually I needed to use the view to launch it.. so this worked fine..
thanks for the tip!
protected void onListItemClick(ListView l, View v, int position, long
id) {
super.onListItemClick(l, v, position, id);
v.showContextMenu();

Anyone have an example of how to do this, I can get it to work with no
problems with a long press, but my users are missing the menu and just
thinking the ListView does nothing.

[android-developers] Re: Using sensors and orientation - lat/lon point to screen coordinates
however, I can never seem to get accurate screen coordinates
of the points.
Could you specify what exactly your problem is?
Does it not work *at all*, or does it work basically, but points are
off by a few degrees? Or does it only work in one orientation of the
device (like in landscape mode), and fails in other orientations?

Hi,
I want to find the screen coordinates (X,Y) where a point represented
by a latitude/longitude value would appear on the screen if you
pointed your phone at it (much in the same way as Wikitude does).
Here is my code from my onSensorChanged() method:
public void onSensorChanged(SensorEvent event) {
Sensor sensor = event.sensor;
int type = sensor.getType();
switch (type) {
case Sensor.TYPE_MAGNETIC_FIELD:
mags = event.values.clone();
isReady = true;
break;
case Sensor.TYPE_ACCELEROMETER:
accels = event.values.clone();
break;
case Sensor.TYPE_ORIENTATION:
orients = event.values.clone();
break;
}
if (mags != null accels != null isReady) {
isReady = false;
SensorManager.getRotationMatrix(R, I, accels, mags);
SensorManager.remapCoordinateSystem(R,
SensorManager.AXIS_X, SensorManager.AXIS_Z, outR);
SensorManager.getOrientation(outR, values);
azimuth = convert.radToDeg(values[0]);
pitch= convert.radToDeg(values[1]);
roll = convert.radToDeg(values[2]);
}
}
I convert the points I wish to project from their lat/lon spherical
coordinates to Cartesian coordinates and perform a perspective
projection using the roll, pitch and azimuth values returned by the
sensor, however, I can never seem to get accurate screen coordinates
of the points.
The matrices for roll, pitch and azimuth I use are:
// pan
double[][] azimuthMat = {
{Math.cos(azimuthValue), -Math.sin(azimuthValue), 0},
{Math.sin(azimuthValue), Math.cos(azimuthValue), 0},
{0, 0, 1},};
// tilt
double[][] pitchMat = {
{Math.cos(pitchValue), 0, Math.sin(pitchValue)},
{0, 1, 0},
{-Math.sin(pitchValue), 0, Math.cos(pitchValue)},
};
// roll
double[][] rollMat = {
{1, 0, 0},
{0, Math.cos(rollValue), -Math.sin(rollValue)},
{0, Math.sin(rollValue), Math.cos(rollValue)},
};
I also perform the necessary translation of the projection cener and
the point to project e.g:
// Translate the point
subtract(pointToProject, projectionCenter);
... where 'pointToProject' and 'projectionCenter' are double arrays
holding the Cartesian coordinates of each location (i.e. camera lat/
lon and the point to project lat/lon)
I realise this is quite a complicated question to ask and I haven't
provided all my projection code etc, however if someone feels they can
help me out and may know how to achieve what i'm after - i'll post the
whole code.
Thanks

As kevin.gaudin pointed out in reply to my bug report, it worked for

This is very stange... I experienced the same problems that you for
some days, and now after comlaining and submitting a bug, it suddently
works without any changes to my code. In my case, I setup a
IntentFilter for some Mime Types, and opened an attached VCF-File in
the Email App with the Open Button. It starts my activity in this
way:
Starting activity: Intent { action=android.intent.action.VIEW

So everything is fine with the Email app. Even the Mime type is
somehow getting through (that is, I think so, because how else would
Android know to delegate this Intent to my app?)
But I still experience the same problems with the Gmail App. It
supplies a Preview button and a click starts a download but yields
The attachment could not ne fetched because this type of file cannot
be displayed on the phone. Maybe I need to adjust my IntentFilter to
handle the file:// protocol, I'll try that and report about it.

You can go there and star the issue to get notified on updates.
I also looked into the source of theEmailapp. It's completely
incredible how many layers of indirection are involved after clicking
on the download button (which will not even be visible if the media
type is not supported) or the preview button. It finally ends up in
com.android.email.activity.MessageView.Listener.loadAttachmentFinished
(Account, Message, Part, Object) and if this is NOT a download, then
this code will be executed (at least I think so, I currently can't
debug it):
Uri uri = AttachmentProvider.getAttachmentUri(
mAccount,
attachment.part.getAttachmentId());
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(uri);
intent.addFlags
(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);
As you can see, there is no intent.setType(), so any IntentFilter that
filters by type will not receive this intent.

Hi all,
I've written an app that can handle the VIEW action for a given

AndroidManifest.xml the Browser automatically uses my app to open
downloads of that type:
intent-filter
action android:name=android.intent.action.VIEW/

TheGMailapp also tries to use my app to Previewattachmentsof that

file:// URI. I guess I need to use a ContentProvider to get the
attachment data, I haven't looked into that yet.
But the real mystery is theEmailapp... there just doesn't seem any
way to make it open theattachments.
Any pointers? Openingattachmentsis a very common requirement of
course, and I would expect the Android platform to encourage
developers to write apps to handle more mime types. Instead I couldn't
find any answers:

Generally speaking, using views instead of activities saves memory but requires more development time. I recommend you first make three activities and a menu, and then optimize for memory/speed/etc as needed.

What if I do another thing... and code four views for each case and swap them using setContentView() in the same activity? Suppose that I'll override the onSaveInstanceState() to save the state of the views in all the four cases. What is the disadvantage in this approach besides having a huge activity that I'm sure it gets closed every time the system is low in memory? I haven't tested it yet, but I didn't find anything in the docs that could stop this approach to work. The reasons for avoiding the usual implementation is that I need to convert an application from J2ME and having multiple activities raises some difficulties in the porting process.

[android-developers] TextView and not common characters?
Good afternoon, I've got a little problem with encoding and displaying a not common characters. The following word comes from a html page which i download: Br#xFC;no Shows as followed in my browser: Brüno I use unescapeHtml ( http://commons.apache.org/lang/api/org/apache/commons/lang/StringEscapeUtils.html ) to convert the #xFC; character into something meaning full. But when i try to display the result on a widget for example a TextView it shows like: Br?no (where the ? is a image of a question mark) I suspect i'm missing one step. Can anyone give me a helping hand? Kind regards, Twan --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Using sensors and orientation - lat/lon point to screen coordinates
The main problem is when I use the values returned by the sensor
manager as is i.e. not modifying them in any way, the points are no
where near where they should be. For example, say the point I wish to
project is due north of my current location and at the same elevation.
I shouldn't need to tilt (pitch) the phone up or down and when I hold
the phone in the direction of north it should appear somewhere near
the center of the phone screen. However, this is not the case, in
reality for the point to appear on the center of the screen I need to
do something like tilt the phone at the ground and orient it in a
easterly direction for example.
I have made a nasty fix which means I subtract 90 from the roll or add
45 degrees to the pitch etc. However while this now projects the point
on the center of the screen it ruins the projections of any other
points (as I have fundamentally altered the sensor values). In my
current implementation a point north of me may work but any points to
the south do not work.
My problem is probably something to do with the coordinates of the
phone differing from my projected coordinates, but making the two
work together is causing me some serious headaches.
I can send you my projection code if it helps, I have really exhausted
all ideas to solve my issue!

// roll
double[][] rollMat = {
{1, 0, 0},
{0, Math.cos(rollValue), -Math.sin(rollValue)},
{0, Math.sin(rollValue), Math.cos(rollValue)},
};
I also perform the necessary translation of the projection cener and
the point to project e.g:
// Translate the point
subtract(pointToProject, projectionCenter);
... where 'pointToProject' and 'projectionCenter' are double arrays
holding the Cartesian coordinates of each location (i.e. camera lat/
lon and the point to project lat/lon)

provided all my projection code etc, however if someone feels they can

I should add I am holding the phone horizontally (as you would when
taking a photo).
As such I modify the sensor values like:
SensorManager.getRotationMatrix(R, I, accels, mags);
SensorManager.remapCoordinateSystem(R,SensorManager.AXIS_X,
SensorManager.AXIS_Z, outR);
SensorManager.getOrientation(outR, values);
I'm assuming thats the correct way to do it.

[android-developers] Re: Associate app to open email attachments
This is very stange... I experienced the same problems that you for
some days, and now after comlaining and submitting a bug, it suddently
works without any changes to my code. In my case, I setup a
IntentFilter for some Mime Types, and opened an attached VCF-File in
the Email App with the Open Button. It starts my activity in this
way:
Starting activity: Intent { action=android.intent.action.VIEW
data=content://com.android.email.attachmentprovider/f70bd905-0a85-4355-
a56f-a41ef6e20100.db/222/RAW flags=0x1 comp={com.companyname/
com.companyname.ActivityName} }
So everything is fine with the Email app. Even the Mime type is
somehow getting through (that is, I think so, because how else would
Android know to delegate this Intent to my app?)
But I still experience the same problems with the Gmail App. It
supplies a Preview button and a click starts a download but yields
The attachment could not ne fetched because this type of file cannot
be displayed on the phone. Maybe I need to adjust my IntentFilter to
handle the file:// protocol, I'll try that and report about it.

[android-developers] possible bug in android browser when accessing site with htaccess/htpasswd?
I have decided to set up my personal, private webserver and to serve myself files that I do not need to have on my sdcard, yet which I'd still like to be accessible through my G1 - mainly media files (ringtones, notifications, some Note Everything backup notes and a few .apk in case my sdcard dies on me), nothing major really. Due to privacy issues, I decided to password protect the folder that had my files in, so I turned to .htaccess + .htpasswd, as I would not want anyone but me to have access to those files. And here comes the interesting part: Android's browser does ask me for the username/password as soon as I attempt to access that folder through my site, which I can enter and it'll take me to the folder's content; however, as soon as I try to download any of those residing files, it labels them as Unknown and the download appears to be corrupt (filesizes do not match). This has been tested on 3G/Edge AND Wifi. Now to assure you that apache and its configuration (httpd.conf) is not the culprit, my systems at home can all access the files just fine. And to further analyze the problem, I decided to download Opera Mini (free off the market) and after going through the same process, it actually allows me to access my password protected folder AS well as download the files correctly. It appears to me that the problem may be a minor bug in android's browser, but please correct me if I'm wrong. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Does OpenGL implementation support GL_AMD_compressed_* extensions?
Does anyone had successfully used ATI compressed textures? I've tried GL_ATC_RGB_AMD, GL_ATC_RGBA_EXPLICIT_ALPHA_AMD and GL_ATC_RGBA_INTERPOLATED_ALPHA_AMD with no success. According to libagl's source these formats are dropped with GL_INVALID_ENUM, but I may miss something. Any ideas? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: why glReadPixels return Alpha always -1
BaoXu, There is a conversion that needs to be made when calling glReadPixels (). OpenGL uses unsigned bytes, and Java uses signed bytes. To convert, cast the byte to an int. If the value is negative, then add 256. In your particular example, a returned alpha value of -1, cast to an int, +256, results in a value of 255. This is full alpha.
