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.
