Thanks for the response.
I'm pretty sure that's not it because I've put a debug statement first
off in the broadcast receiver's onReceive method and that isn't
appearing either. It almost seems that the activity's thread just
isn't getting switched to - so far I've only tested in the emulator,
could the emulator not be switching back to the activity's thread?
I've posted the seemingly relevant chunks of code below if that helps.
ACTIVITY ...
public class AudioProcessor extends Activity {
private AudioInterface service;
private ServiceConnection svcConn = new ServiceConnection(){
public void onServiceConnected(ComponentName className, IBinder
binder){
service = AudioInterface.Stub.asInterface(binder);
}
public void onServiceDisconnected(ComponentName className){
service = null;//NL = probably do more in onService
methods
}
};
private BroadcastReceiver receiver = new BroadcastReceiver(){
public void onReceive(Context context, Intent intent){
Log.d("SHOWING!!!!!!!!!!!", "!!!!!!!!!!!!!!!!!!!");
showMessage(context, intent);
}
};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent serviceIntent = new Intent(this, AudioService.class);
bindService(serviceIntent, svcConn, BIND_AUTO_CREATE);
registerReceiver(receiver, new IntentFilter
(AudioService.BROADCAST_ACTION));
serviceIntent.setAction
("com.linnell.audioprocessor.AudioService");
startService(serviceIntent);*/
}
public void showMessage(Context context, Intent intent){
Log.d("SHOWING!!!!!!!!!!!", "!!!!!!!!!!!!!!!!!!!");
try{
String message = service.showMessage();
new AlertDialog.Builder(this).setTitle("Suggestion")
.setMessage(message)
.setNeutralButton("Close", new
DialogInterface.OnClickListener(){
public void onClick(DialogInterface dlg, int
sumthin){
//do nothing - it will close on its own
}
})
.show();
}
catch(final Throwable t){
Log.e("ERROR", "ERROR IN CODE");
svcConn.onServiceDisconnected(null);
}}}
SERVICE ...
public static final String BROADCAST_ACTION = "new_message";
private Intent broadcast = new Intent(BROADCAST_ACTION);
private Handler serviceHandler;
private Process myProcess;
public IBinder onBind(Intent intent) {
return mBinder;
}
@Override public void onCreate() {
super.onCreate();
myProcess = new Process();
serviceHandler = new Handler();
serviceHandler.post(myProcess);
}
@Override public void onDestroy() {
super.onDestroy();
shutdownService();
}
private final AudioInterface.Stub mBinder = new AudioInterface.Stub()
{
public String showMessage(){
serviceHandler.post(myProcess);
return message;
}
public void stopService(){}
};
class Process implements Runnable{
public void run(){
//run then sits on a while(1), occasionally doing a sendBroadcast
(broadcast);
I know a lot of the stuff in onCreate would be better in onResume, etc
- I'm planning on cleaning all this up once the functionality is
there. :)
