Android Service Testing

Question

How to test my IBinder object that Service return on onBind ?

Answer 1

It's according to the remote interface that you use between your context and the service (in remote call scenario). For example you can do like this:

IBinder service = this.bindService(new Intent(TestService.class.getName()));
assertNotNull(service);
assertTrue(service instanceof ITestServiceCall); //see if the service returns the correct interface
ITestServiceCall iTestServiceCall = ITestServiceCall.Stub.asInterface(service);
assertNotNull(iTestServiceCall);
iTestServiceCall.doSomething();

The ITestServiceCall is the interface that you define in an AIDL file (ITestServiceCall.aidl).

But before this can work you have to make sure your service returns the Stub of your interface correctly on onBind().

I hope this can help.
