Body
An activity instantiates a ResultReceiver and overrides onReceiveResult. The activity then sends an Intent to an IntentService and includes the ResultReceiver as an extra. Once the IntentService is finished processing it sends a message back to the ResultReceiver and processes it in onReceiveResult. The issue is if the user navigates away from the Activity then the result is still sent back to the ResultReceiver which causes all types of issues. Is there not a way to stop this behavior? I've tried stopping the IntentService in the activity's onDestroy() but the result is still sent back. Here is a sample Activity <pre><code>public class Foo extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Intent i = new Intent(this, SampleIntentService.class); i.putExtra("receiver", mReceiver); startService(i); } @Override public void onDestroy() { stopService(new Intent(this, SampleIntentService.class)); mReceiver = null; super.onDestroy(); } ResultReceiver mReceiver = new ResultReceiver(new Handler()) { @Override protected void onReceiveResult(int resultCode, Bundle resultData) { // Handle response from IntentService here } }; } </code></pre> Here is a sample IntentService <pre><code>public class SampleIntentService extends IntentService { public SampleIntentService() { super(SampleIntentService.class.getName()); } @Override protected void onHandleIntent(Intent intent) { ResultReceiver rec = intent.getParcelableExtra("receiver"); if (rec != null) { rec.send(200, null); } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
