Re: [android-developers] What is a "binder thread"?
As I know, they take control over Activity interaction also, because we use IPC to communicate between Activity. There is also a limitation of data we can transmit over a BinderThread, usually < 1MB.

[android-developers] Ending a Thread Safely
Hi Stuart,
Can you determine whether the life cycle of the thread is bound to
which? The SurfaceView or the Activity,
I think the common control should have a callback to let you know that
its life cycle is come to an end (onDestroyed or onSurfaceDestroyed),
you can try to join the Thread at that time, and make sure you have a
well control Thread( extends Thread and define some variable to control
the run()), stop it and join it will help you let the Thread end safely,
as it will have no call back to the object bind the thread when the
object is destroyed.
I cannot provide a sample code, but the concept should be:
SafeThread extends Thread {
boolean stop = false
run() {
while (!stop)
...
}
stop(){
stop = true;
}
}
and
onDestroyed() {
safeThread.stop();
safeThread.join();
}
BR,
Nam

Re: [android-developers] browse picture gallery
Hi Zeeshan,
In Android, we have a Gallery as native app, you can try to send the
Intent.ACTION_GET_CONTENT to get the picture,
This is the sample code:
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.setDataType("image/*");
startActivityForResult(i)
and in onActivityResult, we will get an intent with the uri in the data
of the intent.

Nam

Re: [android-developers] Re: While Loop Stall the rest of the program
Hello ArcDroid,
>From my experience, the design concept should be as follow:
We will have 2 threads:
Main Thread will provide a call back for Image Thread to set image to
ImageView.
Image Thread will download/ load the bitmap, then use the call back to
set Bitmap to ImageView.
The call back can be either a method/ function in Main Thread that's
wrapped by runOnUiThread or implemented by Handler of Main Thread.
You can also try to update the ImageView in runOnUiThread, but that's
not a good design, however, it will work.

Nam
