I am Working on Android System app, that means I signed it with the platform key and I pushed it into "/system/priv-app", but when I check it with "adb shell ps" I found the user is "u0_a40" not "system"
Who can explain me what happen and what can I do to run the app with the system user?
The AndroidManifest.xml
needs to specify that your app is supposed to run as system
user:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.mysystemapp"
android:sharedUserId="android.uid.system"
coreApp="true">
For completeness sake, if you want to compile your system app as part of the AOSP build process via an Android.mk
file, you need to put this in the Android.mk
:
LOCAL_PRIVILEGED_MODULE := true
LOCAL_CERTIFICATE := platform
This ensures that the app ends up in /system/priv-app
and is signed by the platform key.
