如何测试 Service 在 onBind 上返回的 IBinder 对象?

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

推荐答案

这取决于你在上下文和服务之间使用的远程接口(在远程调用场景中).例如，您可以这样做:

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();

ITestServiceCall 是您在 AIDL 文件 (ITestServiceCall.aidl) 中定义的接口.

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

但在此之前，您必须确保您的服务在 onBind() 上正确返回接口的存根.

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