+  * [[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''
