Just like apps on mobile devices and other form factors, some capabilities offered by XR apps require your app to [declare permissions](https://developer.android.com/training/permissions/declaring#add-to-manifest) in your app's AndroidManifest file. In the case of dangerous permissions, your app may need to [request runtime permissions](https://developer.android.com/training/permissions/requesting). Read [Permissions on Android](https://developer.android.com/guide/topics/permissions/overview) and [permission best practices](https://developer.android.com/training/permissions/usage-notes) for more in-depth information. The following permissions can be used by XR apps. All of the permissions in this section are considered dangerous permissions, so you must declare them in your app manifest **and** request them at runtime. ### android.permission.EYE_TRACKING_COARSE Representing the user's eye pose, status, and orientation, such as for use with avatars. Use this permission when low-precision eye tracking data is needed. ### Jetpack XR SDK N/A ### OpenXR Extensions - [`XR_ANDROID_eye_tracking`](https://developer.android.com/develop/xr/openxr/extensions/XR_ANDROID_eye_tracking) - [`xrGetCoarseTrackingEyesInfoANDROID`](https://developer.android.com/develop/xr/openxr/extensions/XR_ANDROID_eye_tracking) ### Unity Features - [Android XR: AR Face](https://docs.unity3d.com/Packages/com.unity.xr.androidxr-openxr@0.4/manual/features/faces.html) ### android.permission.EYE_TRACKING_FINE Eye gaze for selection, input, interactions, and eye-tracked foveated rendering. ### Jetpack XR SDK N/A ### OpenXR Extensions - [`XR_EXT_eye_gaze_interaction`](https://registry.khronos.org/OpenXR/specs/1.1/html/xrspec.html#XR_EXT_eye_gaze_interaction) - [`xrGetFineTrackingEyesInfoANDROID`](https://developer.android.com/develop/xr/openxr/extensions/XR_ANDROID_eye_tracking) - [`XR_META_foveation_eye_tracked`](https://registry.khronos.org/OpenXR/specs/1.1/html/xrspec.html#XR_META_foveation_eye_tracked) - [`XR_VARJO_foveated_rendering`](https://registry.khronos.org/OpenXR/specs/1.1/html/xrspec.html#XR_VARJO_foveated_rendering) ### Unity Features - [Eye Gaze Interaction](https://docs.unity3d.com/Packages/com.unity.xr.openxr@1.13/manual/features/eyegazeinteraction.html) ### android.permission.FACE_TRACKING Tracking and rendering facial expressions. ### Jetpack XR SDK N/A ### OpenXR Extensions - [`XR_ANDROID_face_tracking`](https://registry.khronos.org/OpenXR/specs/1.1/html/xrspec.html#XR_ANDROID_face_tracking) - [`XR_ANDROID_face_tracking_data_source`](https://developer.android.com/develop/xr/openxr/extensions/XR_ANDROID_face_tracking_data_source) ### Unity Features - [`XRFaceTrackingFeature`](https://developer.android.com/develop/xr/unity/reference/class/Google/XR/Extensions/XRFaceTrackingFeature) ### android.permission.RECORD_AUDIO Recording audio input, such as for audio-driven face tracking data sources. ### Jetpack XR SDK N/A ### OpenXR Extensions - [`XR_ANDROID_face_tracking_data_source`](https://developer.android.com/develop/xr/openxr/extensions/XR_ANDROID_face_tracking_data_source) ### Unity Features N/A ### android.permission.HAND_TRACKING Tracking hand joint poses and angular and linear velocities;
