Embedded Android #4 - Using and Customizing the Android Framework
summary
Covers the Android framework internals: the service manager and binder IPC, Dalvik/ART and zygote, and the list of Java system services plus native daemons like installd, vold, netd and keystore. Shows concrete tooling and commands: service call, am/pm and dumpis/dumpstate/bugreport, VDC/NDC and monkey. Demonstrates changing system UI (removes the phone-signal icon in status_bar source), rebuilds the emulator image, and verifies the icon is gone.
