    I develop a custom tablet used Android 9.

    I've tried to build a system app into '/system/priv-app', but after the device startup is completed, it automatically shuts down and transitions to the "Android Recovery" screen.

    what do I have to do to get my device to boot successfully?

    my system app is same as that shown on the following website,
    and fixed a mk below.


    # LOCAL_SDK_VERSION := current
    added "LOCAL_PRIVATE_PLATFORM_APIS" insted of "LOCAL_SDK_VERSION" for successful compilation.

    and also, this app probably doesn't need any permissions with whitelist.
    I run 'development/tools/privapp_permissions/privapp_permissions.py', but the results is empty like this.
    <?xml version="1.0" encoding="utf-8"?>

    Thank you in advance for your support.
