Android的许可 - CHANGE_COMPONENT_ENABLED_STATE

问题描述

我需要使用android.permission.CHANGE_COMPONENT_ENABLED_STATE权限在我的code，因为我需要更新我的项目的另一个APK的组件，但它不似乎真的为我工作。

i need to use android.permission.CHANGE_COMPONENT_ENABLED_STATE permission in my code because i need to update the component of another apk of my project, but it don't seems really work for me

这是我的code：

<permission
    android:name="android.permission.CHANGE_COMPONENT_ENABLED_STATE"
    android:protectionLevel="signatureOrSystem"/>

final int permission = ctx.checkCallingPermission(android.Manifest.permission.CHANGE_COMPONENT_ENABLED_STATE);

final boolean allowedByPermission = (permission == PackageManager.PERMISSION_GRANTED);
L.d(TAG, "allowedByPermission :" + allowedByPermission + " permission:" + permission);
if(allowedByPermission) {}

allowedByPermission总是登录虚假..不知道如果我能错过了什么？

allowedByPermission always log a false.. not sure if i could miss something?

推荐答案

首先，你的应用程序将需要＆LT;使用-许可＆GT; ，不是 ＆LT;许可＆GT;

First, your app would need <uses-permission>, not <permission>.

二，你的应用程序不能持有该权限，除非它被安装在系统分区（例如，通过一个植根设备用户）或通过签订系统固件相同的签名密钥签名。

Second, your app cannot hold that permission, unless it is installed on the system partition (e.g., by a rooted device user) or is signed by the same signing key that signed the system firmware.
