Should explicitly set android:allowBackup to true or false (it's true by default, and that can have some security implications for the application's data)

解决方案：

<application

        android:allowBackup="true"
或

<application

        android:allowBackup="false"

注意：android:allowBackup 必须是application中第一个标签键值对。
