System APPs

Android system APPs are these APPs which are installed in system partition. Since system partition is read only at runtime, thus the system APPs are not remove-able for general user.

Add/Remove system APP

In general, there are two ways to add/remove system applications.

  • At build time

System application configurations for android build system are located under source code folder vendor/olpx/xo4/apps/ To add an application in system partition simply do:

    • copy pre-built APK file to vendor/olpx/xo4/apps/


  • At runtime

This relies on Android OTA update system which allow the system reboots into recovery mode then mount system partition as RW for applying system partition changes.
XO-4 does NOT support runtime system partition update since recovery mode haven't been implemented.
