This plugin helps you query/request runtime permissions synchronously on Android M and later. It also works on older Android versions and detects whether a requested permission is declared in AndroidManifest or not.
How To
Simply import RuntimePermissions.unitypackage to your project and you are good to go! There is one optional step, though: by default, Unity shows a permission dialog on startup to prevent plugins from crashing/malfunctioning. This can be disabled, if you want; but you must make sure to handle all the runtime permissions carefully in your app's lifecycle. To disable this dialog, add the following line inside the <application>...</application> tag of Plugins/Android/AndroidManifest.xml:
<meta-data android:name="unityplayer.SkipPermissionsDialog" android:value="true" />NOTE: if your project doesn't have an AndroidManifest, you can copy Unity's default one from C:\Program Files\Unity\Editor\Data\PlaybackEngines\AndroidPlayer (it might be located in a subfolder, like 'Apk') to Assets/Plugins/Android (credit).
You can use the following static functions of AndroidRuntimePermissions to manage runtime permissions:
Permission CheckPermission( string permission ): checks whether or not the permission is granted. Permission is an enum that can take 3 values:
- Granted: permission is granted
- ShouldAsk: permission is not granted yet, but we can ask the user for permission via RequestPermission function. As long as the user doesn't select "Don't ask again" while denying the permission, ShouldAsk is returned
- Denied: we don't have permission and we can't ask the user for permission. In this case, user has to give the permission from app's Settings. This happens when user selects "Don't ask again" while denying the permission or when user is not allowed to give that permission (parental controls etc.)
Permission[] CheckPermissions( params string[] permissions ): queries multiple permissions simultaneously. The returned array will contain one Permission entry per each queried permission
Permission RequestPermission( string permission ): requests a permission from the user and returns the result. It is recommended to show a brief explanation before asking the permission so that user understands why the permission is needed and doesn't click Deny or worse, "Don't ask again"
Permission[] RequestPermissions( params string[] permissions ): requests multiple permissions simultaneously
void OpenSettings(): opens the settings for this app, from where the user can manually grant permission(s) in case a needed permission's state is Permission.Denied
Example Code
The following code requests WRITE_EXTERNAL_STORAGE permission (it must be declared in AndroidManifest) when bottom-right corner of the screen is touched:
void Update()
{
if( Input.GetMouseButtonDown( 0 ) && Input.mousePosition.x > Screen.width * 0.8f && Input.mousePosition.y < Screen.height * 0.2f )
{
AndroidRuntimePermissions.Permission result = AndroidRuntimePermissions.RequestPermission( "android.permission.WRITE_EXTERNAL_STORAGE" );
if( result == AndroidRuntimePermissions.Permission.Granted )
Debug.Log( "We have permission to access external storage!" );
else
Debug.Log( "Permission state: " + result );
// Requesting WRITE_EXTERNAL_STORAGE and CAMERA permissions simultaneously
//AndroidRuntimePermissions.Permission[] result = AndroidRuntimePermissions.RequestPermissions( "android.permission.WRITE_EXTERNAL_STORAGE", "android.permission.CAMERA" );
//if( result[0] == AndroidRuntimePermissions.Permission.Granted && result[1] == AndroidRuntimePermissions.Permission.Granted )
// Debug.Log( "We have all the permissions!" );
//else
// Debug.Log( "Some permission(s) are not granted..." );
}
}
