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/olpc/xo4/apps/ To add an application in system partition simply do:
- Copy pre-built APK file to vendor/olpx/xo4/apps/
cp YourAPKName.apk vendor/olpc/xo4/apps/
- Add build description in Android.mk under vendor/olpx/xo4/apps
include $(CLEAR_VARS) LOCAL_MODULE := YourAPKName LOCAL_MODULE_OWNER := xxxx LOCAL_SRC_FILES := $(LOCAL_MODULE).apk LOCAL_MODULE_CLASS := APPS LOCAL_MODULE_TAGS := optional LOCAL_CERTIFICATE := platform LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX) include $(BUILD_PREBUILT)
- Add module name in apps.mk under vendor/olpx/xo4/apps
PRODUCT_PACKAGES += \ ....... \ ....... \ YourAPKName
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.
