POAndroid bindService not working
text
Body
copied!<p>I'm having an issue with <code>bindService()</code>. I'm trying to do the binding in a constructor, providing an Intent that contains two parcleable extras. The constructor is being called in <code>onResume()</code> and the service, in its <code>onBind()</code> method, parses the two extras and may return <code>null</code> as a result of the parsing.</p> <p>When I first run the app (through the Run in Eclipse) the binding is (expectedly) rejected by the service: the service's <code>onBind()</code> method is called and returns <code>null</code>. However, the <code>bindService()</code> method, on the application side, returns <code>true</code> (it shouldn't, as the binding did not go through!).</p> <p>This gets more problematic when I try the following: I press the HOME button and start the app again (so its <code>onResume()</code> runs again and the app tries to bind to the service again). This time the service's <code>onBind()</code> seems not to be even run! But the app's <code>bindService()</code> still returns <code>true</code>!</p> <p>Below is some sample code that should help you understand my issue.</p> <p>The application side:</p> <pre><code>// activity's onResume() @Override public void onResume() { super.onResume(); var = new Constructor(this); } // the constructor public Constructor(Context context) { final Intent bindIntent = new Intent("test"); bindIntent.putExtra("extra1",extra_A); bindIntent.putExtra("extra2",extra_B); isBound = context.bindService(bindIntent, connection, Context.BIND_ADJUST_WITH_ACTIVITY); log("tried to bind... isBound="+isBound); } </code></pre> <p>The service side:</p> <pre><code>private MyAIDLService service = null; @Override public void onCreate() { service = new MyAIDLService(getContentResolver()); } @Override public IBinder onBind(final Intent intent) { log("onBind() called"); if (intent.getAction().equals("test") { ExtraObj extra_A = intent.getParcelableExtra("extra1"); ExtraObj extra_B = intent.getParcelableExtra("extra2"); if (parse(extra_A,extra_B)) return service; else { log("rejected binding"); return null; } } } </code></pre> <p>The <code>ServiceConnection</code> that I'm using holds the following <code>onServiceConnected()</code> method:</p> <pre><code>@Override public void onServiceConnected(final ComponentName name, final IBinder service) { log("onServiceConnected(): successfully connected to the service!"); this.service = MyAIDLService.asInterface(service); } </code></pre> <p>So, I never get to see the "successfully connected to the service!" log. The first time I run the app (through Eclipse) I'm getting the "rejected binding" log as well as "isBound=true", but from there on I only get the "isBound=true", the "rejected binding" doesn't come up ever again.</p> <p>I suspect that this might have to do with a possibility of Android recognizing that there was a successful bind even when I forced the rejection. Ideally, I would be able to force an 'unbind' too, but that's not possible: I suspect this because, when I kill the app, I'm getting a log that's located in the <code>onUnbind()</code> method of the service (even though there should be no binding in the first place!).</p>
