第一步：

adb logcat 取出log

從log中可以看出是沒有新增許可權導致的問題。

第二步

新增許可權，檔案地址：frameworks/base/data/etc/privapp-permissions-platform.xml

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

這些許可權都是這個應用在AndroidManifest.xml中申請的許可權。
