| | |
| | For apps to have root access they need to be system apps. For KitKat the app needs to be in ''/system/priv-app'' with 644 permissions. |
| | * Example: ''cat /sdcard/SecureSetting.apk > /system/priv-app/SecureSetting.apk'' (cp works too) |

| | ==== Emulator ==== |
| | To give emulator root: |
| | - change to directory where emulator is located, probably something like: ''~/.android/avd'' |
| | - start the emulator yourself with an incantation similar to: ''~/Android/Sdk/emulator/emulator -avd Nexus_4_API_19 -writable-system -selinux disabled -qemu -enable-kvm'' |
| | - in emulator shell: ''mount -o rw,remount /system'' |

| | ==== Tips and Tricks ==== |
| | * [[https://android.googlesource.com/platform/frameworks/base/+/master/cmds/bootanimation/FORMAT.md|change boot animation]] |
| | * when compressing the animation to a zip, make sure the zip is uncompressed (use the ''-0'' flag) |
| | * for script to run on boot add/create ''/system/etc/install-recovery.sh'' |
| | * Mount system RW: ''mount -o rw,remount /system'' |
| | * Mount system RO: ''mount -o ro,remount /system'' |
