Android 源码中添加APK到system/priv-app下，无法开机

第一步：

adb logcat 取出log

从log中可以看出是没有添加权限导致的问题。

第二步

添加权限，文件地址：frameworks/base/data/etc/privapp-permissions-platform.xml

</permissions>
..........................
  <privapp-permissions package="com.xxx.app.activation">
        <uses-permission name="android.permission.RECEIVE_BOOT_COMPLETED"/>
        <uses-permission name="android.permission.READ_PHONE_STATE"/>
        <uses-permission name="android.permission.FOREGROUND_SERVICE"/>
        <uses-permission name="android.permission.ACCESS_COARSE_LOCATION" />
        <uses-permission name="android.permission.ACCESS_FINE_LOCATION" />
        <uses-permission name="android.permission.ACCESS_NETWORK_STATE" />
        <uses-permission name="android.permission.ACCESS_WIFI_STATE"/>
        <uses-permission name="android.permission.INTERNET"/>
        <uses-permission name="android.permission.CHANGE_NETWORK_STATE"/>
　　　　　 <uses-permission name="android.permission.CHANGE_COMPONENT_ENABLED_STATE"/>
　　　　   <uses-permission name="android.permission.PACKAGE_USAGE_STATS"/>

    </privapp-permissions>
</permissions>

这些权限都是这个应用在AndroidManifest.xml中申请的权限。
