当我将android.permission.UPDATE_DEVICE_STATS添加到我的应用程序时发生错误 [英] when I add android.permission.UPDATE_DEVICE_STATS to my app.error occur

问题描述

我开发了一个需要获得android.permission.UPDATE_DEVICE_STATS权限的应用.但是，当我将此权限添加到应用的AndroidMainfest.xml文件中时，会出现以下错误:

I developed an app which needs to get the android.permission.UPDATE_DEVICE_STATS permission. However, when I add this permission to my app's AndroidMainfest.xml file, I get this error:

权限仅授予系统应用程序"

"Permission is only granted to system apps"

我该怎么做才能将我的应用程序更改为系统应用程序?还有其他方法可以解决此问题吗?

What can I do to change my app to system app? Are there any other ways to solve this problem?

推荐答案

最重要的是要知道:系统应用程序只能由植根设备的人来运行.这意味着如果您没有root用户的设备，则无法测试和运行自己的应用程序.

Most importantly to know: A system app can only be run by people who have rooted their device. Meaning you can't test and run your own application if you don't have a rooted device.

您可以通过按如下所示在AndroidManifest.xml中设置sharedUserId来声明您的应用程序作为系统应用程序运行

You can declare your app to run as a system app by setting the sharedUserId as follows in the AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="[your package name]"
        android:sharedUserId="android.uid.system">

否则，您必须使用系统密钥对应用程序进行签名，请参见此线程如何在具有系统权限的情况下编译Android应用程序

Otherwise you have to sign your application with system key , see this thread How to compile Android Application with system permissions
