I am trying to check if my app has access to storage:

 if (ContextCompat.checkSelfPermission(SplashActivity.this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {

        Toast.makeText(getBaseContext(), "merry christmas", Toast.LENGTH_LONG).show();

    }

this only works when the storage permission is not in the manifest. It stops showing toast when i add the permission. Seems like this code checks if the manifest has the permission instead of if the permission is granted. How do I fix this???

You have to manually ask the user for allowing permission with following code. And then check that if permission is granted or not.

@Override

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);

    if(permitted()){

        // prompting permission dialog

        // permform your task

     }



 }





@Override

public void onResume() {

    super.onResume();

    if (permitted(PERMISSIONS))

        load();

}



@Override

public void onRequestPermissionsResult(int requestCode, String permissions, int grantResults) {

    super.onRequestPermissionsResult(requestCode, permissions, grantResults);

    switch (requestCode) {

        case 1:

            if (permitted(permissions)) {

                load();

            } else {

                Toast.makeText(context, R.string.not_permitted, Toast.LENGTH_SHORT).show();

            }

    }

}

public static final String PERMISSIONS = new String{Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE};



boolean permitted(String ss) {

    for (String s : ss) {

        if (ContextCompat.checkSelfPermission(context, s) != PackageManager.PERMISSION_GRANTED) {

            return false;

        }

    }

    return true;

}



boolean permitted() {

    for (String s : PERMISSIONS) {

        if (ContextCompat.checkSelfPermission(context, s) != PackageManager.PERMISSION_GRANTED) {

            ActivityCompat.requestPermissions(getActivity(), PERMISSIONS, 1);

            return false;

        }

    }

    return true;

}

Your code only works if the permission is not granted. If it didn't run then that permission was granted either during installation or from the data of the previous apk. Just go to settings, choose your app and revoke the permission or select the clear data option and try again.

This is how I do it

   if (!checkPermission()) {  // this line checks permission everytime you access this activity

            Toast.makeText(context, R.string.not_permitted, Toast.LENGTH_SHORT).show();

       requestPermission();

   } else {

       enableGPS();

   }  









public boolean checkPermission() {

        int result = ContextCompat.checkSelfPermission(this, ACCESS_FINE_LOCATION);

        return result == PackageManager.PERMISSION_GRANTED;

    }



    public void requestPermission() {

        ActivityCompat.requestPermissions(this, new String{ACCESS_FINE_LOCATION}, REQUEST_CODE_ASK_PERMISSIONS);

    }  



@Override

    public void onRequestPermissionsResult(int requestCode, String permissions, int grantResults) {

        if (requestCode == REQUEST_CODE_ASK_PERMISSIONS) {

            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                enableGPS();

            } else {

                Toast.makeText(getApplicationContext(), "Please allow access to continue!", Toast.LENGTH_SHORT).show();

            }

        }

    }
