imgView.setBitmap can not be called from any other thread than the
main thread (i.e. thread on which you created your view).
do this instead:
handler.post(new Runnable() {
public void run() {
imgView.setBitmap(bm);
}
});
The 'handler' can be created by just calling 'new Handler()' on the
main thread, e.g. when you create your worker-thread.
public MyThread extends Thread {
Handler handler;
public MyThread() {
super();
handler = new Handler();
}
public void run() {
..
...
handler.post(new Runnable() {
public void run() {
imgView.setBitmap(bm);
}
});
...
}
}
