Android - binding to service
- by tommy
Hi: I can't seem to get an activity to bind to a service in the same package.
The activity looks like this:
public class myApp extends TabActivity {
static private String TAG = "myApp";
private myService mService = null;
private ServiceConnection mServiceConn = new ServiceConnection(){
public void onServiceConnected(ComponentName name, IBinder service) {
Log.v(TAG, "Service: " + name + " connected");
mService = ((myService.myBinder)service).getService();
}
public void onServiceDisconnected(ComponentName name) {
Log.v(TAG, "Service: " + name + " disconnected");
}
};
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
doBind();
Log.i(TAG, "Started (UI Thread)");
// set content
setContentView(R.layout.main);
Resources res = getResources(); // Resource object to get Drawables
TabHost tabHost = getTabHost(); // The activity TabHost
... add some tabs here....
tabHost.setCurrentTab(0);
}
private void doBind(){
Intent i = new Intent(this,myService.class);
if( bindService(i, mServiceConn, 0 )){
Log.i(TAG, "Service bound");
} else {
Log.e(TAG, "Service not bound");
}
}
}
Then the service:
public class myService extends Service {
private String TAG = "myService";
private boolean mRunning = false;
@Override
public int onStartCommand(Intent intent, int flags, int startid) {
Log.i(TAG,"Service start");
mRunning = true;
Log.d(TAG,"Finished onStartCommand");
return START_STICKY;
}
/*
* Called on service stop
*/
@Override
public void onDestroy(){
Log.i(TAG,"onDestroy");
mRunning = false;
super.onDestroy();
}
@Override
public IBinder onBind(Intent intent) {
return mBinder;
}
boolean isRunning() {
return mRunning;
}
/*
* class for binding
*/
private final IBinder mBinder = new myBinder();
public class myBinder extends Binder {
myService getService() {
return myService.this;
}
}
}
bindService returns true, but onServiceConnection is never called (mService is always null, so I can't do something like mService.isRunning() )
The manifest entry for the service is just:
<service android:name=".myService"></service>
I was copying the code direct from the Android developers site, but I must have missed something.
