[android-developers] Will Android Fast Emulator be supported by future AMD Zen processors?
These days new excavator based cpus for the new AM4 socket and chipset will be released, and at the last part of the year, the new Zen AMD processors are being released. In the requisites for Android Fast Emulator I can read this: https://developer.android.com/studio/index.html#Requirements For accelerated emulator: 64-bit operating system and Intel® processor with support for Intel® VT-x, Intel® EM64T (Intel® 64), and Execute Disable (XD) Bit functionality So are AMD users forgoten in the black hole of desperation? or will be supported by zen?

[android-developers] MapView (Maps V2) not working
Welcome all
The tiles of the map are not being updated, the only way to update them is
to block the device (onPause called) and to unblock the device (onResume
called). If i do that, the tiles become updated it is very strange
i mean that if i move the finger doing zoom or moving the map, the map is
frozen, and it only reresh it's state when i block and unblock the device
all the permissions are fine and the api key also is fine in the manifest
this is my code:
public class MainActivity extends Activity {
MapView map;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
LinearLayout main = new LinearLayout(this);
main.setLayoutParams(new
LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT));
GoogleMapOptions options = new GoogleMapOptions();
options.mapType(GoogleMap.MAP_TYPE_SATELLITE)
.compassEnabled(false)
.rotateGesturesEnabled(false)
.tiltGesturesEnabled(false);
options.camera(new CameraPosition(new LatLng(0, 0), 1, 0, 0));
map = new MapView(this, options);
map.onCreate(savedInstanceState);
main.addView(map);
setContentView(main);
}
@Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
map.onResume();
}
@Override

[android-developers] ObjectAnimator starting with a frame jump on Android 4.4 (nexus 5) but not in 4.1 device
I have a simple activity that shows an animation with ObjectAnimator. The animation is created and started in onCreate method of the activity, it is a very simple animation: cloudAnim = ObjectAnimator.ofFloat(cloud1ImageView, x, sw); cloudAnim.setDuration(35000); cloudAnim.setRepeatCount(ValueAnimator.INFINITE); cloudAnim.setRepeatMode(ValueAnimator.RESTART); cloudAnim.setInterpolator(null); cloudAnim.start(); it simply displays a cloud on the left of the screen and moves from the left to the right. The problem is that in my nexus 5 (android 4.4 lastet version) the cloud is doing a frame jump when the activity starts. This jump is only visible in my nexus 5, because i'm testing the app also in a huawei ascend y300 devide with android 4.1 and the jump is not visible, the movement is very smooth.

[android-developers] Infinite ObjectAnimator decreasing framerate progressively...¿why?
Hi
i'm displaying 20 views at same time in the screen. They are inside a
layout, and i'm moving them from top of the screen to the bottom with an
ObjectAnimator.
Each time one view has reached the bottom, the animation is restarted.
The problem is that when 10-15 minutes have passed, the screen starts
decreasing the frame rate, with some jumps in the animations. Why? there
are allways the same objects, and the same animations... why it is
decreasing the framerate progresively?
Some of my code:
fall = ObjectAnimator.ofFloat(view, y,-height, sh);
fall.setDuration(fallTime);
fall.setInterpolator(null);
fall.setRepeatCount(ValueAnimator.INFINITE);
fall.setRepeatMode(ValueAnimator.RESTART);
fall.addListener(new AnimatorListener() {
@Override
public void onAnimationCancel(Animator animation) {}
@Override
public void onAnimationEnd(Animator animation) {
freeBurger();
}
@Override
public void onAnimationRepeat(Animator animation) {}
@Override
public void onAnimationStart(Animator animation) {}
});
fall.start();

[android-developers] MotionEvent.ACTION_CANCEL allways called inmediatly after MotionEvent.ACTION_DOWN
Welcome all
I'm developing an augmented reality app that consists in a camera view with
some linear layouts on the screen representing the position of a POI in the
camera.
The LinearLayouts contains some view elements that implements
onTouchListener and have the action to open a new activity when ACTION_UP
event is called.
The problem is that ACTION_UP is never called. When i press on one of the
POIs on the camera screen, the element calls ACTION_DOWN and instantly
after that, ACTION_CANCEL is being called.
I read that ACTION_CANCEL occurs when the parent takes possession of the
motion, for example when the user has dragged enough across a list view
that it will start scrolling instead of letting you press the buttons
inside of it. You can find out more about it at the viewgroup documentation
of onInterceptTouchEvent.
The problem is that i dont understand what i'm doing wrong.
This is my code of the ontouch in the element that it is displayed on the
linearlayout representing a POI on the camera AR View:
public class Element implements OnTouchListener{...
@Override
public boolean onTouch(View v, MotionEvent event) {
if( event.getAction() == MotionEvent.ACTION_DOWN){
return true;
}else if( event.getAction() == MotionEvent.ACTION_UP){
parent.doAction(this.action);
return true;
}else if(event.getAction() == MotionEvent.ACTION_MOVE){
return true;
} else if(event.getAction() == MotionEvent.ACTION_CANCEL){
return true;
}
return true;
}
Thanks

[android-developers] Problems with ContentProvider for sharing assets image
Im using the solution of this website:
http://www.nowherenearithaca.com/2012/03/too-easy-using-contentprovider-to-send.htmlto
share images from assets folder, but it is not working. The share panel
is being opened, but when i select gmail, google+ or some other social
sharing network, the image is not being shared.
The method public AssetFileDescriptor openAssetFile(Uri uri, String mode)is not
being called when i try to share an image, and the image is not
being shared.
Logcat tells this: No content provider found for permission check:
content:/com.appname/img319030.jpg
I created a class called AssetsContentProvider on my com.appname.utilpackage
and i added this line to my manifest:
provider android:name=com.appname.util.AssetsContentProvider
android:authorities=com.appname/
The class that is trying to use ACTION_SEND to share the image is located
on the package com.appname.actions, and it simply does this:
Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType(image/jpg);
Uri theUri = Uri.parse(content:/com.appname/img319030.jpg);
shareIntent.putExtra(Intent.EXTRA_STREAM,theUri);
SectionManager.getCurrentActivity().startActivity(Intent.createChooser(shareIntent,
));
The image is called img319030.jpg and it is located in assets folder.
This is my AssetsContentProvider class:
public class AssetsContentProvider extends ContentProvider{
@Override
public AssetFileDescriptor openAssetFile(Uri uri, String mode) throws
FileNotFoundException {
AssetManager am = getContext().getAssets();
String file_name = uri.getLastPathSegment();
if(file_name == null)
throw new FileNotFoundException();
AssetFileDescriptor afd = null;
try {
afd = am.openFd(file_name);
} catch (IOException e) {
e.printStackTrace();
}
return afd;//super.openAssetFile(uri, mode);
}
@Override
public int delete(Uri uri, String selection, String[] selectionArgs) {
return 0;
}
@Override
public String getType(Uri uri) {
return null;
}
@Override
public Uri insert(Uri uri, ContentValues values) {
return null;
}
@Override
public boolean onCreate() {
return false;
}
@Override
public Cursor query(Uri uri, String[] projection, String selection,
String[] selectionArgs, String sortOrder) {
return null;
}
@Override
public int update(Uri uri, ContentValues values, String selection, String[]
selectionArgs) {
return 0;
}}

[android-developers] How to prompt the user only to download one language? (Text To Speech)
Hi
I'm trying to do a text to speech test application, seeing this tutorial:
http://android-developers.blogspot.com.es/2009/09/introduction-to-text-to-speech-in.html
I tryed doing what the tutorial says, and i'm setting the language only to
spanish:
mTts = new TextToSpeech(this, this);
mTts.setLanguage(new Locale(spa));
The problem is that when the app starts, the app prompts me to a screen
asking me download four languages, GERMAN, SPANISH, FRENCH, ITALIAN. If i
only download spanish language and then i press back key, the app works,
but EACH TIME i start the app, it shows me the same screen to download the
other three languages, and only stop appearing if i download the foru
languages.
My objective is to prompt the user to download ONLY spanish, and to show
the languages download dialog only one time, not allways.
I'm testing it on a Nexus S phone with 4.1
This is the full code:
public class MainActivity extends Activity implements OnInitListener {
private static final int MY_DATA_CHECK_CODE = 0;
EditText editText;
Button button;
private TextToSpeech mTts;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
editText = (EditText) findViewById(R.id.editText);
button = (Button) findViewById(R.id.button);
editText.setText(Estoy probando, probando y probando, porque hay que
probar.);
Intent checkIntent = new Intent();
checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
startActivityForResult(checkIntent, MY_DATA_CHECK_CODE);
mTts = new TextToSpeech(this, this);
mTts.isLanguageAvailable(new Locale(spa));
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
mTts.speak(editText.getText().toString(),
TextToSpeech.QUEUE_FLUSH, null);
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent
data) {
if (requestCode == MY_DATA_CHECK_CODE) {
if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
// success, create the TTS instance
mTts = new TextToSpeech(this, this);
mTts.setLanguage(new Locale(spa));
} else {
// missing data, install it
Intent installIntent = new Intent();
installIntent.setAction(
TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);

}
}

[android-developers] Issues getting Galaxy Nexus (4.2.1) Camera Megapixels with this function
Hi
I'm getting the camera megapixels with this function:
private String getCameraMegapixels(Camera cam){
Camera.Size size;
size = cam.getParameters().getPictureSize();
DecimalFormat localDecimalFormat = new DecimalFormat(#.#);
return localDecimalFormat.format(size.width * size.height /
100.0D);
}
It works fine for front and back camera in all the phones i tested but but
in Galaxy nexus. In galaxy nexus something is going wrong because i'm
getting that the camera (front and back) haves 0.1 megapixels
Is something wrong with galaxy nexus and the way to get megapixels?
PD: Galaxy Nexus Android version is 4.2.1
Thanks

the camera is set to maximum res, and also, both cameras gives me 0.1

If I'm not totally mistaken Camera.getParameters stores the currently set

getSupportedPictureSizes()http://developer.android.com/reference/android/hardware/Camera.Parameters.html#getSupportedPictureSizes%28%29and
find the highest available resolution from there.

This is the code now (this code is on the handler that is being called
each
second from a thread). el is the expandableListView and mAdapter is the
adapter for the expandableListView
TextView tv = (TextView) mAdapter.getChildView(1, 0, true,
(TextView)el.getChildAt(1), el);
tv.setText(My New Text);
The child is not changing, so something is going wrong... :/
what adapter are you extending?

[android-developers] Re: Efficient way to update one of the childs of a ExpandableListView group?
I tryed to adapt your code by adding this into the handler of my activity:
int first = el.getFirstVisiblePosition();
int last = el.getLastVisiblePosition();
int cnt = last - first + 1;
String tag = Integer.toString(1);
for (int i = 0; i cnt; i++) {
View v = el.getChildAt(i);
if (tag.equals(v.getTag())) {
mAdapter.getChildView(1, 0, false, v, el);
break;
}
}
Also im adding this to each child view in the madapter:
auxTextView.setTag(Integer.toString(groupPosition));
But didn't works, the view is not being updated...
please, can you tell me how to correct my code? i can't adapt your code to
mine to solve this

for (int i = first; i = last; i++) {
TextView v = (TextView)el.getChildAt(i);
it can give an exception? or it's the better way?

When performance is important, you can walk the list of visible item
views, find the one you need to update, and do it right there. You will
want to use listView.getFirstVisibleItem / getLastVisibleItem / getChild.
Also there is a callback, AbsListView.onScrollListener, which lets you
know when the list view is scrolling, and perhaps suspend your updates if
necessary.

ExpandableListView and then calls this method to refresh the view and
show
the updated data to the user: ((BaseExpandableListAdapter)
mAdapter).**notifyDataSetChanged();
This is the update handler:
infoUpdateHandler = new Handler(){
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
children[2][0]=getUpdatedInfo(**);
((BaseExpandableListAdapter)
mAdapter).notifyDataSetChanged**();
}
};
The problem is that when i'm scrolling the expandable list view, i
can see how the scroll is showing low performance, it stops sometimes.
I
think that it is because this call ((BaseExpandableListAdapter)
mAdapter).**notifyDataSetChanged(); is updating all the
ExpandableListView.
*Does not exist a better way to update a expandable list view?
Maybe a way to update only the child that you want to update?*
Thanks

Re: [android-developers] Efficient way to update one of the childs of a ExpandableListView group?
What? where should i put that view? i dont understand you...
the objective is to update one item instead of rebuilding the entire
{expandable} list view.
So... what should i do with that view? how can i make that view to be
refreshed when i want?
i'm stuck

[android-developers] How to get back camera info in android 1.6 to 2.2?
in Android 2.3 (API 9), google introduced CameraInfo to check if the given
camera is the back camera or the front camera in a phone with two cameras:
http://developer.android.com/reference/android/hardware/Camera.CameraInfo.html
With this example you can get info from FRONT camera: How to open front
camera on android
platform?http://stackoverflow.com/questions/2779002/how-to-open-front-camera-on-android-platformand
it's the same for BACK camera.
OK, but the problem is that i need to get info from BACK camera in a phone
with android 2.2. The phone haves two cameras, front and back, and when i'm
trying to get info of the camera, it returns the info of the FRONT CAMERA.
I used this code:
if (Build.VERSION.SDK_INT = 8){
Camera cam = Camera.open();
s +=buMain Camera:/u/bbrbr;
s += bMegapixels: /b+getCameraMegapixels(cam) + megapixels;
s += getCamExtraInfo(cam);
cam.release();
}
I want to get the info from the main camera (the back camera), but that
code gives me info from the front camera I'm sure there is a way to get
the info from the back camera on Android 2.2 and lower devices.
Someone knows it?
Thanks

[android-developers] How to check if an Android phone has front and rear facing cameras?
Hi I need to detect if the phone has a front facing camera, and if so, I need to calculate the megapixels. The same thing goes for a rear facing camera. I know how to get the megapixels of a Camera object, but I don't know how to check for the other things. P.s.: I would also be nice if you know a way to check if the Camera has flash or not, and other cool statistics about the camera -- -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] LEFT JOIN and ORDER BY modified behavior between android 4 and lower versions?
i have an app that makes this SQL query to a database with two tables, a table with items and a table with datesets.

[android-developers] HorizontalScrollView inside HorizontalScrollView ¿making it possible?
I want to learn how to solve this problem. I want to have a Horizontal scrollview with the scroll blocked (the user should not be able to scroll it) and inside that horizontal scrollview i want to have another horizontal scroll view, and this scrollview must be able to be scrolled by the user (it haves more content that the width of the screen). It is possible to do it? i tryed using this on the parent horizontal scroll view: ((HorizontalScrollView) view).setHorizontalScrollBarEnabled(false); ((HorizontalScrollView) view).setEnabled(false); ((HorizontalScrollView) view).setFocusable(false); ((HorizontalScrollView) view).setFocusableInTouchMode(false); and this on the child horizontal scroll view: ((HorizontalScrollView) view).requestFocus(); It is not working, The child appears to have a scroll bar but it cannot be scrolled. How can this be solved? PD: I know that this is not a good practice, but i want to learn how to achieve this goal.

[android-developers] Problems invalidating a View
I have an app with a layout that loads some remote images. When the remote
image is being loaded, a clock with 100 forced height is being displayed (i
did it overwriting onDraw from imageview), and when the remote image is
downloaded and ready to be displayed, the clock dissapears and then the
image appears.
It works, but when the image appears did not receive the correct height, it
still haves the height of the clock (100).
I dont know why, because when the image is displayed it calls a handler
wich refresh the view of the image and the container layout of the image
with the new height (365), but it is not working properly.
this is the handler:
Handler handler = new Handler(){
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
if( ((ImageView)view) != null resource != null resource.image
!= null ){
((ImageView)view).setImageBitmap( resource.image );
view.getLayoutParams().height=height;
((ViewGroup)view.getParent()).getLayoutParams().height=height;
((ImageView)view).invalidate();
((ViewGroup)view.getParent()).invalidate();
((ViewGroup)view.getParent()).refreshDrawableState();
view.invalidate();
}
}
};
the handler is being called, the image is being displayed, the height value
on the handler is correct (365), but the image is still being displayed
with the height of the clock (100).
*Also i must say that if i block the screen and unblock the screen, the
image appears with the correct height* (365). It seems that there is a
problem with invalidate().
Thanks all

[android-developers] ObjectInput.readObject() for reading a file object didn't work's when the version of the app is newer than the older app wich creates the object
i have this class:

public Magazines ms=null; //Esta clase contiene el array de previews de

And i use these methods to store the class (SaveState object) in the sdcard
and to read the object from the file into an object again:
public static void saveData(){
ObjectOutput out;
try {
//primero comprobamos si existe el directorio, y si no, lo creamos.
File folder = new File(Environment.getExternalStorageDirectory() +

in.close();
} catch (Exception e) {e.printStackTrace();}
}
I store the object and each time my app is closed and i read the object
from the sdcard each time my app is opened and it works fine. The problem
comes when i created a newer version of my app (1.01). When i start the app
and i try to read the file from the sdcard the file is readed but all the
variables of the object class are empty. and they are really not empty.
What is happening? how can i avoid that?
Thanks.

[android-developers] Problems with HttpClient when the function is used by various devices at same time
Using httpclient (apache credentials) connection to download various
bitmaps with various devices is failing with one is working OK, ¿why?
i'm developing an app for android (java) that it is connecting to a server
to download 50 bitmaps, and i'm using this function each time to download
each bitmap:
public static Bitmap getRemoteBitmap(String url) {
Bitmap bm=null;
HttpClient httpclient = new DefaultHttpClient();
HttpResponse response;
try {
((AbstractHttpClient)
httpclient).getCredentialsProvider().setCredentials(
new org.apache.http.auth.AuthScope(null,-1),
new
org.apache.http.auth.UsernamePasswordCredentials(MagazineStatus._username,
MagazineStatus._password));
response = httpclient.execute(new HttpGet(url));
StatusLine statusLine = response.getStatusLine();
if(statusLine.getStatusCode() == HttpStatus.SC_OK) {
try {
HttpEntity entity = response.getEntity();
InputStream content = entity.getContent();
bm=BitmapFactory.decodeStream(content );
}catch(Exception ex) {Log.e(DBF Error,ex.toString());}
}else {
response.getEntity().getContent().close();
throw new IOException(statusLine.getReasonPhrase());
}
}catch(ClientProtocolException cpe) {Log.e(ClientProtocolException @ at
FPT,cpe.toString());} catch(Exception ex) {Log.e(Exception at
FETCHPROJECTASK,ex.toString());}
return bm;
}
If i try to download the bitmaps with one device, it works fine, but if i
try to download the bitmaps with 3 or 4 devices at the same time, then,
something fails on this function because this line
bm=BitmapFactory.decodeStream(content
); is giving me a a null bitmap, and i dont understand why, because content,
entity, statusLine and response are not null.
These are the values for these variables when the bitmap bm is null:
response:
response (id=830078599368)
entity BasicManagedEntity (id=830078617768)
headergroup HeaderGroup (id=830078599408)

params ClientParamsStack (id=830079041944)
reasonCatalog EnglishReasonPhraseCatalog (id=830004685872)
statusline BasicStatusLine (id=830078599344)
statusLine:
statusLine (id=830078599344)
protoVersionHttpVersion (id=830004713800)
reasonPhraseOK (id=830078599288)
statusCode 200
entity:
entity (id=830078617768)
attemptReusefalse
managedConn null
wrappedEntity BasicHttpEntity (id=830078612272)
content:
content(id=830078617792)
skipBuf null
eofWatcher BasicManagedEntity (id=830078617768)
selfClosed false
I'm doing something wrong? is the connection closed properly? can this be
improved? Any help will be apreciated.
Thanks

[android-developers] Receiving erroneous glitch bitmaps from httclient connection ¿what i'm doing wrong?
I'm connecting to a server to get 50 bitmaps, and i'm using this function
for each bitmap:
public static Bitmap getRemoteBitmap(String url) {
int cont=0; //reintentos
Bitmap bm = null;
do{
if (bm != null){
if (bm.isRecycled()==false)
bm.recycle();
bm=null;
}
HttpClient httpclient = new DefaultHttpClient();
HttpResponse response;
try {
((AbstractHttpClient)
httpclient).getCredentialsProvider().setCredentials(
new org.apache.http.auth.AuthScope(null,-1),
new
org.apache.http.auth.UsernamePasswordCredentials(MagazineStatus._username,
MagazineStatus._password));
response = httpclient.execute(new HttpGet(url));
StatusLine statusLine = response.getStatusLine();
if(statusLine.getStatusCode() == HttpStatus.SC_OK) {
try {
HttpEntity entity = response.getEntity();
InputStream content = entity.getContent();
bm=BitmapFactory.decodeStream(content );
content.close();
entity.consumeContent();
System.out.println();
}catch(Exception ex) {Log.e(DBF Error,ex.toString());}
}else {
response.getEntity().getContent().close();
throw new IOException(statusLine.getReasonPhrase());
}
}catch(ClientProtocolException cpe) {Log.e(ClientProtocolException
@ at FPT,cpe.toString());} catch(Exception ex) {Log.e(Exception at
FETCHPROJECTASK,ex.toString());}
cont++;
}while (bm==null cont11);
System.out.println(INTENTOS PARA BAJARLA: +cont);
return bm;
}
After that, i'm compressing the bitmap with
pageBitmap.compress(Bitmap.CompressFormat.PNG, 100, new FileOutputStream(new
File(Environment.getExternalStorageDirectory()+/Dir/+fm.getId()+/+i+.jpg)));
Sometimes is working fine, but sometimes i'm receiving glitched bitmaps
like this:
[image: Glitched bitmap]
I think that the erroneal bitmap is being received only when the function
must retry itself with another do while iteration. This happens only with
the httpclient connection fails and returns a null bitmap.

[android-developers] Problems putting a RelativeLayout inside a ScrollView
First of all i have a relativeLayout (body_view), and i'm putting a
scrollView (viScroll) inside:
viScroll = new ScrollView( App.app );
viScroll.setVisibility(View.VISIBLE );
viScroll.setGravity(Gravity.CENTER);
RelativeLayout.LayoutParams rlp = new
RelativeLayout.LayoutParams(getDisplayWidth() ,
RelativeLayout.LayoutParams.FILL_PARENT );
body_view.addView(viScroll , rlp );
Now i'm creating a ButtonContainer relativeLayout wich must have some
button views inside:
RelativeLayout.LayoutParams rlp2 = new RelativeLayout.LayoutParams( menu_width
, RelativeLayout.LayoutParams.FILL_PARENT );
rlp2.setMargins(menu_left, 0, 0 , 0 );
buttonContainer = new RelativeLayout( App.app );
buttonContainer.setGravity(Gravity.CENTER);
viScroll.addView(buttonContainer,rlp2);
Now i put the buttons inside the ButtonContainer:
for( int i = 0 ; i nOptions ; i ++ ){
buttons[i] = new ElementButton( App.app );
buttons[i].addToViewAtEnd( buttonContainer );
}
public void addToViewAtEnd( RelativeLayout layout ){
RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(
width , RelativeLayout.LayoutParams.WRAP_CONTENT );
int child_count = layout.getChildCount();
int last_id = child_count 0 ?
layout.getChildAt(child_count-1).getId() : 0;
rlp.addRule( RelativeLayout.BELOW , last_id );
layout.addView( view , rlp );
}
The problem is that my buttonContainer is not being displayed on the center
of the viScroll scrollView. If the main layout BodyView haves low height
then the buttonContainer is not displayed... something is going wrong and i
can't find it.

If it helps then your square is near far clipping plane.

[android-developers] Opengl ES scaling (zoom out) shows rare square tiles on my textures. How to avoid it?
Hi
I'm displaying a OPENGL ES 1.X square with a texture, and the user can zoom
in and out the square scaling it.
When the user zoom's out the square (the square get's scaled going smaller
in the screen) the texture of the square get's rare translucent squares,
like tiles from googlemaps.
I think that the scaling function from OpenGL is now working in the better
way.
How can i improve it?
These are my OpenGL GLSurfaceView main functions:
public void onSurfaceCreated(GL10 gl, EGLConfig config) {
gl.glDisable(GL10.GL_DITHER); //dithering OFF
gl.glEnable(GL10.GL_TEXTURE_2D);//Texture Mapping ON

gl.glClearColor(0,0,0,0); //fondo transparente
gl.glHint(GL10.GL_PERSPECTIVE_CORRECTION_HINT, GL10.GL_NICEST);

[android-developers] Problems locking the screen orientation with ActivityInfo.SCREEN_ORIENTATION_NOSENSOR
I have an activity that shows a scrollview with a lot of linearlayouts with
a lot of imageviews and textviews.
This activity must show two columns in my scrollview if the orientation is
landscape, and it must show one column in my scrollview if the orientation
is portrait.
It works fine. I have this code on the onCreate method:
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
sw=dm.widthPixels;
sh=dm.heightPixels;
if (swsh)
portrait=false;
with that code i can check if the screenorientation is portrait or
landscape, and then, generate one or two columns in my scrollview. So, each
time the user changes the screen orientation, the oncreate get's called
again and check wich is the current screen orientation.
*As i said, it works fine, but here comes the problem:*
This activity shows some buttons for download content from internet using a
AsyncTask that shows a horizontal ProgressBar. If i change the orientation
while i'm downloading the content from internet and showing the
progressBar, then i get a exception like this:

Then, i suposed that i must lock the screen orientation changes when the
user is downloading content and showing the progressbar dialog, and i tryed
it locking and unlocking it with this:
((Activity)
context).setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR);
((Activity)
context).setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);
IT WORK'S FINE IF I'M IN PORTRAIT MODE and after i start downloading
something i try to change to landscape, it blocks the change and works
finde. *But if i'm in landscape mode and i press the button for download
the content from internet and i start the progressbar dialog, then i get
this exception, and no need to try to change the orientation to portrait
mode, i get the exception instantly:*

[android-developers] It is possible to lock the screen orientation of the phone only when you want? (dinamically)
I have an application that can be viewed with landscape and portrait mode. I'm not using onConfigurationChanged() and android:configChanges=orientation|keyboardHidden and the screen orientation change is working perfectly. But now, i have a small problem. I want to learn to lock the screen orientation change of the screen. I mean that for example, when the user press a lock button, the screen orientation must be locked and it must not change, and when the user press again that button, the screen orientation must get unlocked ¿how can i lock the screen orientation dinamically? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] How to store a JPG remote file into the phone internalMemory/sdcard?
I need to add a new functionality into my app. I must store a lot of JPG
images from internet into the Phone.
If the phone haves sdcard, the JPG files must be stored on the sdcard. If
not, they must be stored on the internalMemory, only if the phone haves
space to do it.
Then, i should do these things:
1. Check if the Phone haves SDCARD. If haves, SDCARD dir is the destiny, if
not, INTERNAL MEMORY is the destiny.
2. Check if the phone have space to store the photos.
3. If have space, store the photos into a dir called `/Magazine/`
I know how to get a JPG file from internet and how to transform it into
BITMAP, but it is the only think i know, i dont know how to store it as JPG
and i dont know the other things.

I'm searching in google how to do the things i need, but i can't find any
clear information, i prefeer to ask you for the best way to do this, the
optimal way.

public MagazinePreview(String title, String id, String description,

this.title = title;

Wich is the easiest approach to connect to that PHP and get the XML
and interpret it storing the info on the List of MagazinePreview class
objects?

[android-developers] How to launch OnTouchListener on the elements of a ScrollView but only when the user is not Scrolling?
i have a huge problem managing my horizontal scrollview. It haves inside a
horizontal linear layout with a lot of vertical linear layouts wich haves a
text and a image.
I want that when the user press on the vertical linearlayouts, the
ontouchlistener must be called launching a new feature of my app.
The problem is that when the user scrolls the scrollview, the
ontouchlistener of the verticallinearlayouts is being called, and i dont
want that.
How can this be solved?
Thanks
My code:
final HorizontalScrollView hsv = new HorizontalScrollView(this);
RelativeLayout.LayoutParams hsvParams = new
RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT);
hsvParams.addRule(RelativeLayout.BELOW,6);
hsv.setBackgroundColor(0x55383838);
hsv.setLayoutParams(hsvParams);
hsv.setVisibility(View.GONE); //inicialmente está oculto
LinearLayout hsvll = new LinearLayout(this);
hsvll.setOrientation(LinearLayout.HORIZONTAL);
hsvll.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
hsvll.setPadding(0, 0, 0, 5);
createThumbnails();
List LinearLayout thumbnailLinearLayouts = new ArrayListLinearLayout();
for (int i=1; i=squareGLSurfaceView.pages.size();i++){ //el tope es
=pages.size() porque hay que recordar que se ha añadido una página en blanco
al principio, por lo que la última página será = .size(). Nos guiamos por
pages.size en lugar de thumbnails.size() porque thumbnails.size() puede haber
crecido para añadir una página en blanco al final, que no queremos mostrar
LinearLayout ll = new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
ll.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
ll.setPadding(10, 0, 10, 0);
thumbnailLinearLayouts.add(ll);
TextView tv = new TextView(this);
tv.setText(+(i));
tv.setGravity(Gravity.RIGHT);
ll.addView(tv);
ImageView iv = new ImageView(this);
iv.setImageBitmap(thumbnails.get(i));
ll.addView(iv);
hsvll.addView(ll);
}
hsv.addView(hsvll);
rl.addView(hsv);
for (int i=0;ithumbnailLinearLayouts.size();i++){
final int auxIndex=i;
thumbnailLinearLayouts.get(i).setOnTouchListener(new OnTouchListener(){
@Override
public boolean onTouch(View v, MotionEvent event) {
MagazineStatus.currentPage=auxIndex;
hsv.setVisibility(View.GONE);
return true;}
});

[android-developers] Wich is the best way to destroy a GLSurfaceview and free all the memory?
I have a GLSurfaceView with four polygons with textures. I need to destroy the GLSurfaceview and recreate a new GLSurfaceView with new parameters when the user press a button. I tryed with myGLSurfaceView = null and initializing again myGLSurfaceView with the new paramters, but it is giving me VM budget bitmnap exception. I dont understand why, because i am doing recicle() on all the bitmaps i use. So, i think that i need to destroy all the polygons of my glsurfaceview and my glsurfaceview before tho recreating a new glsurfaceview. Wich is the correct way to achieve this?

[android-developers] How to display a LinearLayout menu aligned to the right of a FrameLayout and 100px below the top of the screen?
I have a FrameLayout (all the screen is the FL) wich haves a openGLview and a header image on the top of the screen. Now i want to display a menu of two buttons, created with a LinearLayout. My LL Menu must be floating on the framelayout, aligned to the right of the screen and must be 100px below the top of the screen. How can i achieve that? i tryed with this code, but is not working, the Menu is being displayed on the left on the screen and it is painting the upper part of the menu, and i dont want that, i need that the upper part of the menu it's not painted with the colour of the menu.

[android-developers] How to load a bitmap texture in a thread on a polygon class?
i'm developing a simple OpenGL ES 1.1 app for android.
I have a GLSurfaceView class that uses a square class that represent's
a square polygon wich is rotating and must change his texture when the
user press a button.
I need to load the bitmap texture on a thread because i dont want to
stop the rotation of the polygon.
I'm having problems with this, the texture is not changing, instead of
that i'm getting white textures.
THis is the code of my square polygon, with the thread on the end of
the code. The method loadBitmap() is the method that changes the
texture and launches the thread.

[android-developers] Problems changing the texture of a polygon in a thread… white textures
In some point of my app i need to changue the texture of a polygon.
For that, i must load a bitmap from assets folder and then i pass the
bitmap to a loadBitmap method of my polygon that changes the
texture.
It is working fine, but i need to move the code into a thread, because
the loading time of the bitmap it's frozing my opengl polygon when
it's loading the bitmap from assets folder.
Because that i implemented a thread that it is called to change the
texture, but something is going wrong because my texture is empty
(white) when i use the thread, but it works if i dont use the thread,
this is my thread code:
public class addNextPage extends Thread
{
GL10 gl;
public addNextPage(GL10 gl) {
super();
this.gl = gl;
}
public void run()
{
super.run();
Bitmap bm=loadImage(pages.get(0));
auxSquare.loadBitmap(context, gl, bm);
squares.set(3,auxSquare);
currentPage+=1;
//vuelvo a recolocar los squares
int posCont=-2; //el primer polígono está a la izquierda, no
se ve.
for (int i=0;isquares.size();i++){
if (squares.get(i)!=null)
squares.get(i).setPosition(posCont,0);
posCont+=2;
}
}
}

[android-developers] How to check when the phone changues from portrait to landscape? (with portrait mode forced in manifest)
I have a special need for my app. I must force the app to work only in portrait mode, but i need to know when the user has moved the phone to landscape mode. Why? because i am displaying a opengl view with a texture image, and when the user changues the phone position to landscape mode i must rotate the polygon without reseting the activity. Then i must force portrait mode on manifest, because i dont want that my onCreate method gets called again. Please, can someone tell me how to achieve this? I know how to rotate the image, i only need to know when the user has moved the phone to landscape position, but with portrait forced on manifest.

[android-developers] How to create a polygon with the dimensions of a texture?
i'm trying to develop a simple opengl ES 1.1 app that must show a
square polygon with a texture. The texture haves a rectangular
resolution of 1536x2048 pixels.
I'm learning opengl with the NEHE tutorials, but they didn't eplain
how to create a polygon with the dimensions of the textures.
This is my actual square.java code, it is doing it by the wrong way.
It receives a bitmap as parameter, and it creates a new scaled bitmap
with square form with POT dimensions, but with square proportions,
this code uses a square polygon, and i dont need that.
what i need to modify to create this polygon with the dimensions of
the texture?

[android-developers] Problems with the width of the bitmap. The width is limited by the height of the screen
Hi I'm creating a bitmap wich i need to use as background of a 320 width screen. The problem is that the bitmap is not getting the width i want. It is getting two empty spaces on the left and on the right. It is because it is fitting the height of the screen, but i dont want that, i want to force the bitmap to have the width i want. Doesn't matter if a portion of the height of the bitmap is out of the screen. i need to force the width when i am adding the image to the layout, i mean that the image must be keep the aspect ratio, but the image must be higher than the height of the screen, and the image must be shown incomplete if the heigh of the image is higher than the height of the screen. Now this is not happening, because the layout is forcing the width to respect the image and show all the height of the image in the height of the screen, then i think the problem is on the layout rules im creating the bitmap with: View view; Bitmap aux = Util.loadImage( filename ); //image loaded but with his original width Bitmap image = Util.scaleBitmap(aux, 320); //scaling to 320 ((ImageView)view).setImageBitmap( resource.image ); RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams( 320 , h ); rlp.addRule( RelativeLayout.CENTER_HORIZONTAL ); rlp.addRule( RelativeLayout.ALIGN_PARENT_TOP ); layout.addView( view , rlp ); What am i doing wrong? -- You received this message because you are subscribed to the Google Groups Android Developers group.

i want that when the phone receives a push notification from AC2M, a notification must be shown in the notification bar, and if the user press on the notification, my app must be started and show a specific activity describing that notification, and not the normal fist activity of my app. It is possible to achieve this? can someone explain me how?
