1. My problem

• Declare

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

• Call permission in code

// Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(thisActivity,
        Manifest.permission.READ_CONTACTS)
        != PackageManager.PERMISSION_GRANTED) {

    // Permission is not granted
    // Should we show an explanation?
    if (ActivityCompat.shouldShowRequestPermissionRationale(
      thisActivity,
      Manifest.permission.WRITE_EXTERNAL_STORAGE)
    ) {
      // Show an explanation to the user *asynchronously* -- don't block
      // this thread waiting for the user's response! After the user
      // sees the explanation, try again to request the permission.
    } else {
      // No explanation needed, we can request the permission.
      ActivityCompat.requestPermissions(
        thisActivity,
        arrayOf(Manifest.permission.WRITE_EXTERNAL_STORAGE),
        MY_PERMISSIONS_REQUEST_READ_CONTACTS
      )

      // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
      // app-defined int constant. The callback method gets the
      // result of the request.
    }
} else {
  // Permission has already been granted
}

• Everything is correct as of the documents, but nothing happens??!
