[android-developers] Creating new directory under out\target\product\*\data
I'm trying to write a makefile for the Android system that copies files from my local filesystem to out/target/product*/data. Is there anyway to create new directories from within the makefile? What I'm doing right now is: file := $(TARGET_OUT_DATA)/media/audio/wolf.mp3 $(file) : $(LOCAL_PATH)/media/audio/wolf.mp3 However, this doesn't create /data/media (and /data/media/audio). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

Re: [android-developers] Utilizing HTTPS
You can use .net clases for https
import java.net.*
import javax.net.ssl.HttpsURLConnection;
{
HttpsURLConnection urlConnection;
urlConnection = (HttpsURLConnection) new URL(actionUrl).openConnection();
BufferedReader in = new BufferedReader(new
InputStreamReader(urlConnection.getInputStream()));
String str;
StringBuffer responseBuffer= new StringBuffer();
while ((str = in.readLine()) != null) {
responseBuffer.append(str);
}

[android-developers] Re: Tiff Codec
Yeah, we can use C function from Android SDK. Please go through with Android
NDK which is provided by Google.
It's just like using C code from Java using JNI.

Re: [android-developers] Re: GetLocation of the phone
Store in a Bundle pass to your activity
public void onLocationChanged(Location loc) {
if (loc != null) {
double lat=loc.getLatitude();
double lon=loc.getLongitude();
Bundle bundle = new Bundle();
bundle.putDouble("lat", lat);
bundle.putDouble("lon", lon);
// Create Intent, store Bundle into Intent and paas intent to
another Activity
information = " "+lat +lon;
Toast.makeText(this, "Location Changed:"+information,
Toast.LENGTH_LONG).show();
}
}
And you can extract these value in OnCreate() of another Activity.
Bundle b = this.getIntent().getExtras();

Re: [android-developers] Re: Inter thread Communication
Tejas, Thanks for very good example. It'll definitely help to setup
communication between threads.
It's mean that if we want to communicate from worker thread to main thread
then we have to setup one another handler (which is assciated with another
message queue) and using same message passing technique (obtainMessage and
sendMessage, handleMessage).
Conclusion, Handler is one-way message passing technique using queue.

Re: [android-developers] Re: Progress bar is run after task completing
Try it, If you want to paas any specific message to UI
then use message object for the same.
like Message msg = handler.obtainMessage();e fucntion
// set any value
// get the same value in hadleMessag
Complete code is here
ProgressBar bar;
Handler handler=new Handler() {
public void handleMessage(Message msg) {
bar.incrementProgressBy(5);
}
};
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
bar=(ProgressBar)findViewById(R.id.progress);
bar.setProgress(0);
Thread background=new Thread(new Runnable() {
public void run() {
try {
for (int i=0;i<20 && isRunning;i++) {
Thread.sleep(1000);
handler.sendMessage(handler.obtainMessage());
}
}
catch (Throwable t) {
// just end the background thread
}
}
}
}

But, there must be some standard way to do this.

Re: [android-developers] Read Gmail from my app
This is the suggestion provide by Mark.
Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("text/plain");
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new
String[]{"t...@email.com"});
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Subject");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Text");
context.startActivity(Intent.createChooser(emailIntent, "Send mail..."));
There is no Uri for sending an email. Instead, you use ACTION_SEND with
text/plain as the MIME type and a suitable set of extras.
By using Intent.createChooser() to create your actual Intent, you will
let the user choose from available email clients how to send the message.

Re: [android-developers] Change the playback rate of a track in real time
Hey, I just gone through with your code. You are not using
public final void setRate (int streamID, float rate)Please take care
streamID is different from soundID. streamID is the value returned by the
play() function.

Re: [android-developers] BroadcastReceiver, Intent objects
Yeah, there's no fucntion available in intent class. But you can putExtra putExtra<http://developer.android.com/reference/android/content/Intent.html#putExtra%28java.lang.String,%20long%29> (String <http://developer.android.com/reference/java/lang/String.html> name, long value) to recongnize any known scenario. On the other end use getExtra to get the same value. There are so many similar function described in intent class, you can try according to your need. - Anurag Singh On Sun, May 2, 2010 at 11:28 AM, Sean Sullivan wrote: > > I've implemented a BroadcastReceiver class to receive Intent objects. > > In my BroadcastReceiver class, I'd like to be able to identify the > source (sender) of the Intent object.

[android-developers] abort()-ing HttpGet requests in ThreadSafeClientConnManager
Hi,
I have an http client based on multi-threaded model of apache http
components in my App. And I want to achieve spontaneous cancellation
of http get requests from my Android app.
A new executor thread is started for each http request and the Thread
and the HttpGet is saved in a thread safe queue. When abort is
requested (on pressing back on the progress dialog and when starting a
new activity) - another thread is started which goes through the queue
of Threads and HttpGet and attempts to terminate them (code below).
While the HttpGet gets aborted successfully, the Threads go into
'native' state. They only time out giving SocketTimeoutException after
a default interval. The threads end up this way on most cancellations.
Is this something to be expected or I am hitting a bug?
The issue is that And as soon as 2 threads enter this state, all
further executor threads go into wait. Only when either of the 2
blocked threads time out, other executors get a chance (this seems to
be the default behavior of http). I have have tried many different
thing but I am unable to budge the 'stuck' threads.
I think the problem can be easily overcome by increasing the total no
of threads and threads per host -- but I am not sure if this will be a
correct thing to do (because the socket resources will stay occupied
till timeout and there is nothing theoretically that can stop a user
to do infinite cancellations)? Even if this is -- for Android, what
should be the number?
Now I am also doubting if my abort strategy is flawed. Can anyone
please commentor let me know of a fool-proof abort strategy?
- - -
Run method of the abort thread is like:
public void run() {
while (!stopQueue.isEmpty()) {
final List stopRequest =
stopQueue.remove();
HttpGet abortRequest = (HttpGet)
stopRequest.get(0);
Thread abortThread = (Thread)
stopRequest.get(1);
// first abort the request
if (abortRequest != null &&
!abortRequest.isAborted()) {
abortRequest.abort();
Log.d("Aborting",
abortRequest.getURI().toString());
}
// if the thread is still stuck -- interrupt it
if (abortThread != null &&
abortThread.isAlive()) {
abortThread.interrupt();
Log.d("Interrupting",
abortThread.getName());
}
}
}
Thanks
Anurag
