Android simple service not starting

问题:

My problem is in the question title, i'm trying to start/bind a simple service with just log in it and it's not working at all. I want to do it with Service Connexion method :

public class testServiceBound extends Service {
    /**
     * PRIVATE ATTRIBUTES
     */
    // log
    private static final String TAG     = testServiceBound.class.getSimpleName();
    private final Binder        _binder = new testBinder();

    @Override
    public void onCreate() {

        Log.i(TAG, "onCreate--");
        super.onCreate();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        Log.i(TAG, "onStartCommand--");
        return START_STICKY;
    }

    @Override
    public void onDestroy() {

        Log.i(TAG, "onDestroy--");
        super.onDestroy();
    }

    @Override
    public IBinder onBind(Intent intent) {

        Log.i(TAG, "onBind--");
        return _binder;
    }

    public class testBinder extends Binder {
        public testServiceBound getServiceInstance() {

            Log.i(TAG, "PlayerBinder--getServiceInstance--");
            return testServiceBound.this;
            }        
    }
}

In the activity :

private testServiceBound        _testService;

public final ServiceConnection  _connectionStreamingtest    = new ServiceConnection() {
                                                                @Override
                                                                public void onServiceConnected(ComponentName className, IBinder testBinder) {

                                                                    Log.i(TAG, "onServiceConnected--");
                                                                    // service
                                                                    testBinder binder = (testBinder) testBinder;
                                                                    _testService = binder.getServiceInstance();
                                                                }

                                                                @Override
                                                                public void onServiceDisconnected(ComponentName arg0) {

                                                                    Log.i(TAG, "onServiceDisconnected--");
                                                                    _bound = false;
                                                                }
                                                            };
public void bindToService() {

    Log.i(TAG, "bindToService--");
    Intent intenttest = new Intent(MainActivity.this, testServiceBound.class);
    startService(intenttest);
}

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Log.i(TAG, "onCreate--");
    //
    // service
    bindToService();
}

In the manifest :

<service
    android:name="com.egdigital.testing.service.testServiceBound"
    android:enabled="true"
    android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE" >
</service>

and i tried with this too

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

No error, no log, nothing happens..

回答1:

You are starting the service explicitly and not binding. So your service connection code won't be firing.

Try this code instead:

Intent intenttest = new Intent(MainActivity.this, testServiceBound.class);
bindService(intenttest , _connectionStreamingtest   , Context.BIND_AUTO_CREATE);

OK at least i found ! Thanks for all the comments and answers =)

<service
    android:name="com.egdigital.testing.service.testServiceBound"
    android:enabled="true"
    android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE" >
</service>

this was not in the application tag !! And of course it needs to be there (1 day to find this..)
