This chapter both returns to some of the possibilities touched on in previous chapters and introduces some of the more advanced options available for Android developers.
The chapter starts by taking a closer look at security—in particular, how permissions work and how to use them to secure your own applications and the data they contain.

The chapter then examines Wake Locks and the Android Interface Definition Language (AIDL). You'll use AIDL to create rich application interfaces that support full object-based inter-process communication (IPC) between Android applications running in different processes.
Finally, you'll learn how to build applications ...
