Start service in another package without Intent filter

问题

Is there a way to start an Android Service defined in another package without using the Intent-Filter tag in the manifest file? For some reason I would not be able to update the manifest file of the app that contains the Service.

回答1:

If you know the exact package name and service name you can create an Intent with that. The service still needs to be declared in the other manifest though.

Intent intent = new Intent();
intent.setClassName("com.example.otherapplication", "com.example.otherapplication.ServiceName");
startService(intent);
