Permission can only be set at AndroidManifest.xml.

As an AI language model, I cannot give a definitive answer without context. However, I can say that AndroidManifest.xml is the primary configuration file for an Android app, and it contains information about the app's components, permissions, and required hardware features. Permissions must be declared in the AndroidManifest.xml file to allow the app to access certain system resources or perform certain actions. Therefore, it is essential to set permissions correctly in the AndroidManifest.xml file to ensure that the app functions correctly and does not violate user privacy or security.

whether Permission can only be set at AndroidManifest.xml.
No, permissions can also be requested and set dynamically at runtime using the ActivityCompat.requestPermissions() method in code. However, certain permissions, such as dangerous permissions, still require explicit user approval even if requested at runtime. Additionally, some permissions can only be set in the AndroidManifest.xml file, such as signature permissions and permissions required for certain features like camera or location services.
AndroidManifest.xml修改SELinux权限
在AndroidManifest.xml文件中,你可以通过`<uses-permission>`标签来声明特定的权限,包括对SELinux安全上下文(Security Enhanced Linux Context,简称SELinux)的控制。SELinux是一种Linux的安全机制,它为应用分配安全策略,允许或限制其访问系统资源。
如果你想修改应用的SELinux权限,通常会涉及到以下部分:
1. `<uses-feature>`标签:如果需要使用某个功能并要求特定的SELinux上下文,可以添加如下配置:
```xml
<uses-feature android:name="android.software.sip" android:required="true" android:supports-gl-texture="secontext=your_context_type"/>
```
这里`your_context_type`是你想要应用的SELinux上下文,比如`selfrule_unconfined_u:object_r:phone_home_net_t:s0`.
2. `<application>`标签下的`<meta-data>`元素:你可以使用`android:name`为`android.permission.SELinuxContext`,`android:value`设置权限:
```xml
<meta-data android:name="android.permission.SELinuxContext" android:value="your_context_type:your_package_name"/>
```
确保将`your_package_name`替换为你的应用包名。
3. 使用`set SELinux context`命令:在AndroidManifest.xml设置之后,还需要在打包应用时通过Gradle插件或Shell脚本为APK设置正确的SELinux上下文。这一步通常是开发者的工作,而不是直接在XML文件中完成的。
注意,更改SELinux权限可能会导致应用无法正常运行,因为它影响到系统的安全策略。在实际操作之前,应该充分了解并测试。
