Android runtime permissions make easy

License Android Arsenal


In marshmallow, android has introduced runtime permission check, that means when application runs, it asks user provide permission to run specific functionality. for example if you using Camera or saving files on external storage or location.

The android basic code to request permission is to complex and tedious to understand (if you don't trust me, check here ???? ). Ask is a library make asking for the particular permission easy for developer. This is very simple and light weight library with just few lines of code and you good to go.

Demo( How it looks!)

Ask for permission Show rationale
show permission show rationale

How to use.

  • Very first step is to include this library in your project by adding following entry into your project's gradle dependencies
dependencies {
	compile 'com.vistrav:ask:2.5'
  • Adding the necessary permissions into your project manifest file
  • Add the following code in your class to request the runtime permissions
import android.Manifest;
import android.os.Bundle;
import android.util.Log;

import com.vistrav.ask.Ask;
import com.vistrav.ask.annotations.AskDenied;
import com.vistrav.ask.annotations.AskGranted;

public class MainActivity extends AppCompatActivity {

    private static final String TAG = MainActivity.class.getSimpleName();

    protected void onCreate(Bundle savedInstanceState) {
                .id(INT_ID_OF_YOUR_REQUEST) // in case you are invoking multiple time Ask from same activity or fragment
                        , Manifest.permission.WRITE_EXTERNAL_STORAGE)
                .withRationales("Location permission need for map to work properly",
                        "In order to save file you will need to grant storage permission") //optional

    public void fileAccessGranted(int id) {
        Log.i(TAG, "FILE  GRANTED");

    public void fileAccessDenied(int id) {
        Log.i(TAG, "FILE  DENiED");

    public void mapAccessGranted(int id) {
        Log.i(TAG, "MAP GRANTED");

    public void mapAccessDenied(int id) {
        Log.i(TAG, "MAP DENIED");
  • The setting rationale message is optional but it would be good in case user has declined the permission, there is chance for developer to explain app user why specific permission is needed
  1. forPermissions method takes one or more permissions as argument
  2. withRationales method takes one or more rationale message, usually it is good to provide same number of rationale messages as number of permissions

IMPORTANT: If your application is running in any android verion lesser than Marshamallow, the all, requested permissions will be granted by default and you can find then in list provided by granted method
