Android: How to safely unbind a service

Question

I have a service which is binded to application context like this:

getApplicationContext().bindService(                     new Intent(this, ServiceUI.class),                     serviceConnection,                     Context.BIND_AUTO_CREATE             );  protected void onDestroy() {             super.onDestroy();                               getApplicationContext().unbindService(serviceConnection);         } 

For some reason, only sometimes the application context does not bind properly (I can't fix that part), however in onDestroy() I do unbindservice which throws an error

java.lang.IllegalArgumentException: Service not registered: tools.cdevice.Devices$mainServiceConnection. 

My question is: Is there a way to call unbindservice safely or check if it is already bound to a service before unbinding it?

Thanks in advance.

Answer 1

Try this:

boolean isBound = false; ... isBound = getApplicationContext().bindService( new Intent(getApplicationContext(), ServiceUI.class), serviceConnection, Context.BIND_AUTO_CREATE ); ... if (isBound)     getApplicationContext().unbindService(serviceConnection); 

Note:

You should use same context for binding a service and unbinding a service. If you are binding Service with getApplicationContext() so you should also use getApplicationContext.unbindService(..)
