PORebinding a background service process (Android)
text
Body
copied!<p>I have been doing some research on this but found no clear answer. </p> <p>The functional challenge is:</p> <p>a) Start an activity with a layout (OK)</p> <p>b) By Button (labeled START) click ist starts a background service (OK)</p> <p>c) While the activity can be closed, the background service must continue to run (OK)</p> <p>d) The background process is still there, I can see it in my notification (OK)</p> <p>e) The activity restarts from the notification (OK)</p> <p>f) The activity must connect to the process and get the status of it back. Simply checking if the service is running and set the label of the start-stop-button from (b) to STOP. </p> <p>e) Hitting the button will stop the service, so that works.</p> <p>Here are some details:</p> <p>The connection to my service LogoTimerService is done in the activity like this:</p> <pre><code>private ServiceConnection mConnection = new ServiceConnection() { @Override public void onServiceConnected(ComponentName className, IBinder service) { // We've bound to LocalService, cast the IBinder and get // LocalService instance LogoTimerServiceBinder binder = (LogoTimerServiceBinder) service; mService = binder.getService(); mBound = true; } @Override public void onServiceDisconnected(ComponentName arg0) { mBound = false; } }; </code></pre> <p>ON RESUME I call this function to actually connect:</p> <pre><code>private void connectLogoTimerService() { Log.i(tag, "-connecting service"); Intent intent = new Intent(this, LogoTimerService.class); startService(intent); bindService(intent, mConnection, Context.BIND_AUTO_CREATE); if (mService!=null) Log.i(tag, "-SERVICE BOUND"); else Log.i(tag, "-Service NOT bound"); } </code></pre> <p>When I start the application the first time, I get a the second (NOT bound) message. </p> <p><strong>Why is it not bound? Is it to slow? (It seems like it playing around.)</strong> </p> <p>If I do not destroy the activity the mService is found.</p> <p><strong>How can I synchronize this, so I can get the status back?</strong></p> <p>I start AND bind the service. Is this correct?</p> <p>I can see that the service is running using this code (I found it on this site, thanks):</p> <pre><code>private boolean isMyServiceRunning() { ActivityManager manager = (ActivityManager) getSystemService(ACTIVITY_SERVICE); for (RunningServiceInfo service : manager .getRunningServices(Integer.MAX_VALUE)) { if (LogoTimerService.class.getName().equals( service.service.getClassName())) { return true; } } return false; } </code></pre> <p>Thank you very much for your help!</p>
