android:isolatedProcess="true"
By the way, I know that it's not answering the question but it might help some people as well - lately, I found out about a great third-party lib that Evernote developers have created. Its name is Android-Job and its aim is to create jobs that run on different processes and can become active again even after a device reboot, it's amazing.
