Basics

The library simplifies the task of requesting permissions for Android M. Just one call and one callback are enough.

Usage

  1. Extend your activity from AllowMeActivity (which extends AppCompatActivity)
public class MyPermissionsActivity extends AllowMeActivity {
   //... more code here
   
}
  1. Request the permission and register the callback for handling. All in one call
        //... more code here
        
        if (!AllowMe.isPermissionGranted(permission)) {
            new AllowMe.Builder()
                    .setPermissions(permission)
                    .setRationale(rationale)
                    .setPrimingMessage(primingMessage)
                    .setRationaleThemeId(themeId)
                    .setCallback(new AllowMeCallback() {
                        @Override
                        public void onPermissionResult(int requestCode, PermissionResultSet result) {
                            if (result.isGranted(permission)) {
                                //... permission is granted, handle here
                            }
                        }
                    }).request(requestCode);
        } else {
            //... handle permission already granted
        }
  • permission is the permission you need to request
  • rationale is optional and it is the string message to show when the user denies the permission for the first time
  • primingMessage is optional and sets the permission priming message dialog that is showed prior to request the permission. In some cases where the dialog requesting the permission appears without any further notice and without enough context, permission priming will help you to put the user in context.
  • themeId is optional and allows to style the rationale alert dialog
  • requestCode is an integer to identify the request

The library makes sure that onPermissionResult is only called when the requestCode matches the user input request code. Anyway, the requestCode is also returned in the callback params so that it can also be checked against the original request code.

And that's all it takes.

It is also possible to request the permissions inside fragments, just extend the parent activity from AllowMeActivity and steps above remain the same.

Priming vs rationale

The permission rationale dialog appears once the user has denied the permission perviously. It is a way to explain the user why we need the permission. But sometimes the first permission request appears with little or no context and, it is then when priming is important. Priming message dialog, when defined, will appear in the first permission request helping to put the user in context as to why the permission is required.

If the user decides not to go ahead after reading the priming message, the permission will not be requested again and the user will need to go to device settings to grant it.

Use annotated methods instead of callbacks

It is possible to, instead of using callback methods, use annotations to define the method to be called when the permission request is performed.

    
    public class MyActivity extends AllowMeActivity {
        
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            
            //... more code here
            
            int requestCode = 69;
            if (!AllowMe.isPermissionGranted(Manifest.permission.READ_CONTACTS)) {
                new AllowMe.Builder()
                        .setPermissions(Manifest.permission.READ_CONTACTS)
                        .setRationale(rationale)
                        .setPrimingMessage(primingMessage)
                        .setRationaleThemeId(themeId)
                        .requestPermissionForResult(MyActivity.this, requestCode);
            } else {
                //... handle permission already granted
            }
        }
                
        @OnPermissionResult(requestedPermissions = {Manifest.permission.READ_CONTACTS})
        void permissionRequestHandler(int requestCode, PermissionResultSet result) {
            //... handle result
        }
    }

The annotation OnPermissionResult receives the list of requested permissions in requestedPermissions param.

To use the annotated method, a new requestPermissionForResult call should be used. This call receives two params:

  • Object with class the annotated method belongs to
  • int with the permission request code

The library will then call the annotated method to handle the permission request result.
