    <p>I'm hoping this is more of an issue with code than anything else and I'm hoping that someone out there can help track down the issue.</p> <p>I have other code that starts the service with startService() and I can verify that the service is started as the debugger hits the onCreate() function of DecoderService.</p> <p>However, the bindService never binds to the running service. Is this an asynchronous call and I have to wait for something to complete?</p> <pre><code>public class ResultsActivity extends Activity { protected void onResume() { // TODO Auto-generated method stub super.onResume(); Intent decoderIntent = new Intent(this,DecoderService.class); _isBound = bindService(decoderIntent,mConnection,Context.BIND_AUTO_CREATE); _textView.start(_mBoundService); } private boolean _isBound = false; private DecoderService _mBoundService; private ServiceConnection mConnection = new ServiceConnection() { public void onServiceConnected(ComponentName className, IBinder service) { _mBoundService = ((DecoderService.LocalBinder)service).getService(); } public void onServiceDisconnected(ComponentName className) _mBoundService = null; } }; } public class DecoderService extends Service { protected void onHandleIntent(Intent intent) { // TODO Auto-generated method stub _numCompleted = 5; _numTotal = 100; } protected int _numCompleted = 0; protected int _numTotal = 0; public void onCreate() { onHandleIntent(null); } @Override public IBinder onBind(Intent intent) { return mBinder; } // This is the object that receives interactions from clients. See // RemoteService for a more complete example. private final IBinder mBinder = new LocalBinder(); public class LocalBinder extends Binder { DecoderService _ref = null; public LocalBinder() { _ref = DecoderService.this; } DecoderService getService() { return DecoderService.this; } } } </code></pre>

    1. COMy activity is running within the Tab widget and apparently in this situation, you have to pass in the getApplicationContext(), instead of your local context.

    2. COAll I can tell you that bindService() is somewhat asynchronous. I was trying to call it in onCreate and then use it later in oncreate and I was getting null pointer exceptions. It seems that it wasn't actually being bound until sometime after onCreate finishes. How do you know it's never binding to the service? Can you post more code where you're actually using the service?

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.
