In our code if both the permissions are not granted an alert dialog is popped showing the mandatory need to request the permissions. onRequestPermissionsResult checks if the permissions are granted or not. Let’s add the permissions into a string array and call the requestPermissions as shown below: String perms =, PERMISSION_REQUEST_CODE).
We’ll display a prompt requesting access to these permissions when the application is launched. Example : Let’s say we want to access the camera and location in our app. The results of the requests will be passed into the method onRequestPermissionResult. If they belong to the same group, then only one dialog prompt would be displayed. Note: Android Permissions belonging to two different groups would prompt the user with an individual dialog for each of them. We can ask for multiple dangerous permissions by passing a string array of permissions. The method requestPermissions(String permissions, int requestCode) is a public method that is used to request dangerous permissions. Enabling anyone of the location permissions enables all. An example of dangerous permission is _LOCATION and _LOCATION.
If the user accepts one permission in a group/category they accept the entire group. Dangerous permissions are grouped into categories that make it easier for the user to understand what they are allowing the application to do.
From Android 6.0 only dangerous permissions are checked at runtime, normal permissions are not. The common thing in both the types is that they need to be defined in the Manifest file. Dangerous and Normal android permissionsĪndroid defines some permissions as dangerous and some as normal. Hence we need to implement this new android permissions model in our application. In the case we try to call some function that requires a permission which user has not granted yet, the function will suddenly throw an Exception( ) that will lead to the application crashing. A user using Marshmallow can revoke the dangerous permissions (we’ll discuss the dangerous and normal permissions later) from the Settings->Apps->Permissions. Now this doesn’t mean that we can work with old model of permissions by setting the sdk version to 22. Thus android runtime permissions support backward compatibility. So the first question that comes to our mind is - Will the older apps run on Android Marshmallow? The answer is yes if the targetSdkVersion is 22 or less. With the introduction of Android 6.0 (SDK 23), users are prompted for some specific permissions at runtime when they become necessary to use. If not handled properly, it can cause application crashes. In this tutorial we’ll look into the new android runtime permissions that are introduced and how to handle them. With the introduction of Android 6.0 Marshmallow, Google has changed the way permissions are handled by the app. Welcome to android runtime permissions example.
