`CameraView` needs two permissions:
|
|
|
|
|
|
|
|
|
|
- `android.permission.CAMERA` : required for capturing pictures and videos
|
|
|
|
|
- `android.permission.RECORD_AUDIO` : required for capturing videos with `Audio.ON` (the default)
|
|
|
|
|
|
|
|
|
|
### Declaration
|
|
|
|
|
|
|
|
|
|
The library manifest file declares the `android.permission.CAMERA` permission, but not the audio one.
|
|
|
|
|
This means that:
|
|
|
|
|
|
|
|
|
|
- If you wish to record videos with `Audio.ON` (the default), you should also add
|
|
|
|
|
`android.permission.RECORD_AUDIO` to required permissions
|
|
|
|
|
|
|
|
|
|
```xml
|
|
|
|
|
<uses-permission android:name="android.permission.RECORD_AUDIO"/>
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
- If you want your app to be installed only on devices that have a camera, you should add:
|
|
|
|
|
|
|
|
|
|
```xml
|
|
|
|
|
<uses-feature
|
|
|
|
|
android:name="android.hardware.camera"
|
|
|
|
|
android:required="true"/>
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
If you don't request this feature, you can use `CameraUtils.hasCameras()` to detect if current
|
|
|
|
|
device has cameras, and then start the camera view.
|
|
|
|
|
|
|
|
|
|
### Handling
|
|
|
|
|
|
|
|
|
|
On Marshmallow+, the user must explicitly approve our permissions. You can
|
|
|
|
|
|
|
|
|
|
- handle permissions yourself and then call `open()` or `setLifecycleOwner()` once they are acquired
|
|
|
|
|
- ignore this: `CameraView` will present a permission request to the user based on
|
|
|
|
|
whether they are needed or not with the current configuration.
|
|
|
|
|
|
|
|
|
|
Note however, that this is done at the activity level, so the permission request callback
|
|
|
|
|
`onRequestPermissionResults()` will be invoked on the parent activity, not the fragment.
|
