[android-developers] How can I download Android Sdk platform-tools without the pain?
Hi just wondering if there is a better way to download the Android/Sdk/platform-tools files. Just having a play with http://flutter.io/ via https://atom.io/packages/dartlang editor and got an error about adb, on my debian jessie, being out of date. Also the other android tools are required to build an apk. So to get platform-tools files for linux, I have to down load the 326M only to find the platform-tools directory empty http://developer.android.com/sdk/installing/index.html?pkg=tools Running the Sdk/tools/android script populated the directory with the missing stuff. What the best way to get a current copy of adb and other tools without having to having java installed and without having to download over 300M? After all this, running adb resulted in an unhelpful file not found error, fixed by adding 32bit stuff in Troubleshooting Ubuntu https://developer.android.com/sdk/installing/index.html?pkg=tools Thanks, so I have no issues now, just what a easy way next time I trash my linux setup. Would be nice to live a java free life too. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: Android custom ImageView fade animation
Hi, I tried it but it doesn't seem to work :( Here's my code in the
view that triggers the thread code in the activity:
case MotionEvent.ACTION_DOWN:
currentTouchIndex = checkForSquareTouch(X, Y);
if (currentTouchIndex = 0)
{
((MainActivity) this.getContext())
.playSquareAnimation(currentTouchIndex);
Activity code:
public void playSquareAnimation(int currentTouchIndex)
{
ranim = AnimationUtils.loadAnimation(this, R.anim.rotate);
// view.squares[currentTouchIndex].startAnimation(ranim);
runOnUiThread(new Runnable()
{
public void run()
{
view.clock.startAnimation(AnimationUtils.loadAnimation(
MainActivity.this,
R.anim.rotate));
}
});
}
Any ideas?
Do you think my view's onDraw() method is messing around with the
animation?

[android-developers] Re: Android custom ImageView fade animation
Just to clarify, if I change
view.clock.startAnimation(AnimationUtils.loadAnimation(
MainActivity.this,
R.anim.rotate));
to:
view.startAnimation(AnimationUtils.loadAnimation(
MainActivity.this,
R.anim.rotate));
Then the animation plays, but for the whole view, which isn't what I
want

It takes too much time when your try to allocate memory for Paint
object. If you work withanimationit always calls invalidate() method
which redraws your View. Memory allocation for Paint should be outside
of onDraw() method (e.g. when you create your view, in it's
constructor) it will give you much better perfomance that you have
now. Try to do so and you'll see.

Bump: Can anyone help? If I define an imageview in my activity and
then set an animation for it, then it plays fine. But if I define an

[android-developers] HTTP post request with HTTP Auth
As the topic indicates I'm trying to perform a http post request to a page

It works from the command line with curl as following:

But with the java code below I get redirected to a login form. Any ideas
what I'm doing wrong?
Note that the username and password I have supplied is working so, if
anyone cares, please try it out. You just have to replace _at_ with @
private void sendDeviceIdToServer(String deviceId) {
DefaultHttpClient client = new DefaultHttpClient();
client.getCredentialsProvider().setCredentials(
new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT),
new UsernamePasswordCredentials(snot_at_snot.dk, supersnot));
//new UsernamePasswordCredentials(snot%40snot%2Edk, supersnot));
HttpPost post = new
HttpPost(http://teletracker.herokuapp.com/devices;);
try {
ListNameValuePair nameValuePairs = new ArrayListNameValuePair(1);
nameValuePairs.add(new BasicNameValuePair(device[name], from
android));
nameValuePairs.add(new BasicNameValuePair(device[device_id],
deviceId));
post.setEntity(new UrlEncodedFormEntity(nameValuePairs));

[android-developers] Sending/Receiving data with Socket
Hi all,
I am having some issues with sending and receiving data to and from a
socket.
This is the class I put together from an example on the web:
[code]
package com.kinrou.android.socket_test;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.InetSocketAddress;

a different thread
boolean result = false;
try {
Log.i(AsyncTask, doInBackground: Creating socket);
SocketAddress sockaddr = new InetSocketAddress(some.url,
9339);
nsocket = new Socket();
nsocket.connect(sockaddr); //10 second connection timeout
if (nsocket.isConnected()) {
nis = nsocket.getInputStream();
nos = nsocket.getOutputStream();
Log.i(AsyncTask, doInBackground: Socket created,
streams assigned);
Log.i(AsyncTask, doInBackground: Waiting for inital
data...);
byte[] buffer = new byte[4096];
int read = nis.read(buffer, 0, 4096); //This is
blocking
while(read != -1){

}
}

//nos.write(cmd.getBytes());

if (result) {
Log.i(AsyncTask, onPostExecute: Completed with an

} else {
Log.i(AsyncTask, onPostExecute: Completed.);
}
}
}
[/code]
the this the way I have am using it:
in onCreate I have this
networktask = new NetworkTask();
networktask.execute();
in onClick I have this
networktask.SendDataToNetwork(som data to the server);
What I am trying to achieve to connect to the socket, send some data
to this socket, when connected the socket would send some data back
which relates to the data sent in the 1st place.
the above class logs the following output at start up

--- when the button is pressed
04-19 11:29:53.591: INFO/AsyncTask(6978): SendDataToNetwork: Writing

I however never get anything back from the server or if I do, I am not

[android-developers] https X509 webview
I need a webview which can connect and auth using x509 certs. 1. One idea which came to mind was that I could override or implement some interface where I could use my own code for creating a secure socket. However I cant seem to get started with this approche. I have read the docs at http://developer.android.com/reference/android/webkit/WebViewClient.html and AFAI can see this would be the class to override. However I'm not sure which methods I should replace. 2. Another way would be implementing the following steps: connect, auth and read the data (the body part of the http response) and load it into a webview intercept onclick or url loading and manually use httplib (or whatever) to read the data and finally load it into the webview again The first idea seems to be the best from a beautiful code perspective... but I need some pointers before thats possible for me. The second solution seems like a hack which actually isnt that big a deal since client certs (most likely) will be supported in futhere versions of the android browser. However I'm not 100% sure that it will actually work. Cookies is one thing which needs to be support by the httplib in question and also shared with the webview in case someone wants to use js to read cookies.

[android-developers] Get GpsStatus notification in a Service
Hi, I'm trying to find a solution to my problem since a few days, without any success for the moment. I would like to get GPS_EVENT_START and GPS_EVENT_STOPPED in a Service. For this, in the Service, I get a reference on LocationManager, then register a listener through addGpsStatusListener. This listener implements GpsStatus.Listener and so override onGpsStatusChanged(int event) to get the events I want. But it doesn't work, the onGpsStatusChanged is never called when the GPS is started/stopped. I don't want to use LocationListener because it is too power consuming for the events I want. Also ACCESS_FINE_LOCATION permission is set. I read in some forums and website that the addGpsStatusListener may doesn't work well on Eclair or Froyo. If you have a working solution to this issue, it can help me a lot. Regards, seb -- You received this message because you are subscribed to the Google Groups Android Developers group.

i'm gonna publish a commentary with a link to your blog in the code, do you

First of all, how are you getting orientation changes on an N1? I
never found a way to get it to do that.
I tested my latest code on www.rbgrn.net on both the N1 and Droid and
both seem to be working well now. It includes your wait-hack and my

Re: RE : [android-developers] Re: Droid 2.1-update1 EGL10.eglCreateWindowSurface() deadlocks intermittently
forget it, your code is fine, it call the surfacechanged right, passing good
values for width and height.
for obvious reasons, my sphere isn't restreched after a rotation (it does
approx 5% of the time only), but all initialization is done
in surfacechanged using passed width and height, it worked fine before, but
not anymore.
anyway the code on the blog look fine, i just had to declare the instanceId
var and cast a return value to Runnable to compile it.

[android-developers] Re: DatePicker: years before 2000
Hi, I've got users with the same problem with the same Samsung Moment Phone. The date can only be set from 2000 to 2090. If the user sets manually 1984, then when he'll go back in the DatePickerDialog, the date is 2098. After a little search, it appears that the DatePicker widget have 2 attributes startYear and endYear that can be set as following to limit for example from 1900-2010 DatePicker xmlns:android=http://schemas.android.com/apk/res/android; android:id=@+id/datePicker android:padding=5dip android:layout_gravity=center_horizontal android:layout_width=wrap_content android:layout_height=wrap_content android:startYear=1900 android:endYear=2010/ But the DatePicker widget is not accessible from the DatePickerDialog and so, thoses values can not be set. So, as I was using DatePickerDialog, I have reimplement this class by using the original code and sets the attributes in the layout xml file as shown.

[android-developers] WidgetLayout inside PreferenceActivity displays new then old bitmap...
Hi, I have a PreferenceActivity designed with a .xml file Inside the .xml, I have: ... Preference android:key=picture android:title=Picture android:widgetLayout=@layout/picture / ... The widgetLayout xml file is a linearlayout with a ImageView inside. I have set a default drawable src attribute to the ImageView: android:src=@drawable/test When launching, the PreferenceActivity is displayed. The test drawable as well. Everything is ok. When I click on the Preference, I have specify to modify the bitmap inside this widgetLayout as following: ImageView img = (ImageView) findViewById(R.id.picture_img); img.setImageBitmap(null); System.gc(); img.setImageBitmap(newBitmap); The newBitmap is then well displayed inside the widgetLayout. I scroll the Preference list (and hide the line that own the widgetLayout) and then scrolling back to make the line reappear. Then, the old bitmap is displayed (@drawable/test) - KO, it should still display the new bitmap. I tried to add: getListView().destroyDrawingCache(); img.invalidate(); But nothing changed...

[android-developers] Re: launching m3u playlist with intent
Hi Marco,
Thank you very much for the response. You give me the key to find the
solution.
I had to study the code of PlaylistBrowserActivity to find the
solution.
I give it here if someone else search the solution:
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setComponent(new ComponentName
(com.android.music,com.android.music.PlaylistBrowserActivity));
intent.setType(MediaStore.Audio.Playlists.CONTENT_TYPE);
intent.setFlags(0x1000);
intent.putExtra(oneshot, false);
intent.putExtra(playlist, playlistid);
startActivity(intent);
and to retrieve the playlistid:
Cursor cursor = getContentResolver().query
(MediaStore.Audio.Playlists.EXTERNAL_CONTENT_URI, null, null, null,
null);
if (cursor != null) {
if (cursor.moveToFirst()) {
do {
playlistid = cursor.getString(cursor.getColumnIndex
(MediaStore.Audio.Playlists._ID));
playList.add(playlist);
} while (cursor.moveToNext());
cursor.close();
}
}
On 16 août, 21:29, Marco Nelissen marc...@android.com wrote:
Well, OK, that's not entirely true. While you can't play an arbitrary
m3u file, you can play playlists that are in the database (which may
have come from m3u files originally, in which case there path is in
the _data column).
To see how, you can look at what happens when you put a shortcut to a
playlist on the home screen and then launch it.

[android-developers] Re: Memory leak - heap size (again)
I think I found a side effect in the native free resources liberation
wich could explain some unexpected java.lang.OutOfMemoryError: bitmap
size exceeds VM budget when we work with large bitmap.
In my application, I work with a lot of big bitmap, a lot of icones,
thumbnail and drawable ressources.
To remove the heap size problem, I work with just one Bitmap at the
same time and when I want to replace this Bitmap in my view, I replace
first the view with a little bitmap (very small in the heap and to
avoid the ondraw error trying to use a recycled bitmap), then I make
a recycle in the big Bitmap and then I replace the big Bitmap with the
new one.
Despite this, I can have a bitmap size exceeds VM budget.
I think this is because when I make a recyle, the ressource are
deleted from the dalvik VM but not immediately from the native heap
size.
I suppose the native memory is remove only if I manualy make a
System.gc()
The problem is maybe that the dalvik VM make a gc if the resources are
missing in the dalvik VM but maybe not if the resources are missing in
the native heap size. You can have a VM wich is low in memory and a
lot of ressources which are growing in the native heap because the GC
is not properly called (that's just an assumption )
You can reproduce the bitmap size exceeds VM budget error easily if
you don't make explicitely System.gc(); just after bitmap.recycle()
(and the error occurs even with only one Bitmap). It work only with
big picture (you can download the project with source and large bitmap
here: http://www.sxercavins.com/AndroidTest.zip ):
public class AndroidTest extends Activity {
ImageView imageView;
Bitmap bitmap;
public static final int NB_ITERATION = 10;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
imageView = (ImageView) findViewById(R.id.iconeAppli);
Button buttIterate = (Button) findViewById
(R.id.iterateWithoutGC);
buttIterate.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
iterate(R.drawable.photo, false);
}});
Button buttIterate2 = (Button) findViewById
(R.id.iterateWithGC);
buttIterate2.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
iterate(R.drawable.photo, true);
}});
}
public void iterate(int ressource, boolean isRunGC){
int iteration = 0;
while(true iterationNB_ITERATION){
try {
if(bitmap!= null !bitmap.isRecycled()){
bitmap.recycle();
if(isRunGC)
System.gc();
Log.d(bitmap is recycled, bitmap is
recycled);
}
/*
* crash here after some iterations if the bitmap size
is big
* even if we do a recycle() and if there no System.gc()
*/
bitmap =
BitmapFactory.decodeResource(getApplicationContext
().getResources(), ressource);
imageView.setImageBitmap(bitmap);
imageView.invalidate();
Log.d(iteration, +iteration++);
System.gc(); //to force the GC and be sure the heap
probleme does not come from the VM
} catch (Exception e) {
e.printStackTrace();
Log.d(IOException, IOException);
}
}
}
}
