        int result = ContextCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE);
        if (result == PackageManager.PERMISSION_GRANTED){
            return true;
        } else {
            return false;
        }
    }

 public void requestPermissionForExternalStorage(){
        if (ActivityCompat.shouldShowRequestPermissionRationale(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE)){
            Toast.makeText(activity, "External Storage permission needed. Please allow in App Settings for additional functionality.", Toast.LENGTH_LONG).show();
        } else {
            ActivityCompat.requestPermissions(activity,new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},EXTERNAL_STORAGE_PERMISSION_REQUEST_CODE);
        }
    }

onRequestPermissionsResult this method is not working @sumit — Bhuvan Arora, Jul 05 '17 at 10:07
what do you mean by not working is it not getting called or what?? — sumit, Jul 05 '17 at 10:08
when i have to code inside this method. it didn't show result. i think compiler is unable to call that method when user granted permission @sumit — Bhuvan Arora, Jul 05 '17 at 10:09
change marshmallowPermissions = new MarshmallowPermissions(getActivity()); to MarshMallowPermission(Context context, Fragment fragment) — akhilesh0707, Jul 05 '17 at 10:09

For Fragment, We have to pass Reference in Class Create Constructor in MarshmallowPermissions Class

public MarshmallowPermissions(Context context, Fragment fragment) {

            Log.e(TAG, "MarshMallowPermission() called with: " + "context = [" + context + "], activity = [" + fragment + "]");
            this.fragment = fragment;
            this.context = context;
        }

public void requestPermissionForFragmentWriteExternalStorage() throws Exception {
        try {
            fragment.requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
                    EXTERNAL_STORAGE_PERMISSION_REQUEST_CODE);
        } catch (Exception e) {
            e.printStackTrace();
            throw e;
        }
    }

public boolean checkPermissionForWriteExternalStorage() {
            int result = context.checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE);
            if (result == PackageManager.PERMISSION_GRANTED) {
                return true;
            } else {
                return false;
            }

        return false;
    }

 marshmallowPermissions = new MarshmallowPermissions(getActivity(),fragment);

still not working. can u please provide me proper working example — Bhuvan Arora, Jul 05 '17 at 10:33

I got the Answer I tried and check permissions in my fragment instead of calling from other class and it works

Apply below code in oncreate of fragment

    if (Build.VERSION.SDK_INT >= 23) {
       checkPermissionForExternalStorage();

    }



    return myView;

}

@RequiresApi(api = Build.VERSION_CODES.M)
public boolean checkPermissionForExternalStorage(){
    int result = ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.WRITE_EXTERNAL_STORAGE);
    if (result == PackageManager.PERMISSION_GRANTED){
        return true;
    } else {
       requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},EXTERNAL_STORAGE_PERMISSION_REQUEST_CODE);
        return true;
    }
}

Override below method in fragment

@Override
    public void onRequestPermissionsResult(int requestCode,
                                           String permissions[], int[] grantResults) {
        Log.d("req_result", "success");
        switch (requestCode) {
            case EXTERNAL_STORAGE_PERMISSION_REQUEST_CODE: {
                // If request is cancelled, the result arrays are empty.
                if (grantResults.length > 0
                        && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// Do your stuff here after user granted permissions
                } else {

                    // permission denied, boo! Disable the
                    // functionality that depends on this permission.
                }
                return;
            }

            // other 'case' lines to check for other
            // permissions this app might request
        }
    }

I am trying to check runtime permissions by calling a class inside fragment. But onRequestPermissionsResult is not working inside fragment
