How can an Android application have more than one process?

Question

I have developed an Android application that has 1 process and 2 services. But I noticed that \"Google Services\" has 2 processes and 1 service. How can it have 2 processes?

Answer 1

If you are looking for examples, do check out hogwarts library, it shall provide you facilities for multi-processes programming in Android.

Basically there are following things you need to have in order to run a service in its "own" process.

1. in AndroidManifest.xml, make sure the service's process attribute is ":remote" or something like it with a ":" prefix
2. use startService() calling to bring up the service from your activity.
3. use AIDL for ipc.
4. Make everything transfer between processes Parcelable. (this is actually the requirement for point 3)
