| | === Giving an app root access === |
| | //Apps need to be system apps to have root-type privs// |
| | * [[https://stackoverflow.com/questions/17222535/create-system-application|How to make your app a system app on a rooted device]] |
| | * [[https://titanwolf.org/Network/Articles/Article?AID=08b12461-41e9-4fa2-9fe9-e40a604cfb53|root run bash-like commands etc.]] |
| | * [[https://medium.com/android-news/system-app-in-android-f003d418b4cc|tutorial on Medium on how to make system apps]] |
| | |
| | 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'' |
| | //not fully tested// |

| | ==== 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'' |
