add to manifest:

   <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />

You may want to change in MainActivity:

    protected void onCreate(Bundle savedInstanceState) {
        ...
        CheckPermissions(new String[] { Manifest.permission.ACCESS_COARSE_LOCATION, Manifest.permission.ACCESS_BACKGROUND_LOCATION,
                Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE,
                Manifest.permission.ACCESS_FINE_LOCATION,   Manifest.permission.BLUETOOTH_ADMIN});

    }

    private void CheckPermissions(String[] aPermission)
    {
        ArrayList<String> aRequest = new ArrayList<String>();
        for (int i=0; i<aPermission.length; i++)
            if (ContextCompat.checkSelfPermission(this,aPermission[i])
                    != PackageManager.PERMISSION_GRANTED)
                aRequest.add(aPermission[i]);

        if (aRequest.size() > 0)
            ActivityCompat.requestPermissions(this, aRequest.toArray(new String[0]), 1);
    }

As i am a beginner i did not care to update 

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