With the latest version of the Android SDK, you do not need to require permissions manually.

A Voximplant application can require the following permissions:










Bluetooth permissions

On Android 12 or higher, the BLUETOOTH_CONNECT permission is required. The permission must be granted before the call. Without granting this permission, Bluetooth audio devices will not be available. There is no need to request the permission on Android 11 or lower.

See Available Roles
Audio and video permissions

The CAMERA and RECORD_AUDIO permissions need a user prompt since Android 6.0 (use the Voximplant.getMissingPermissions method to see the permissions which are not granted by the user).
