"Login to LastFM" dialog crashes app when screen is rotated.

Expected behavior

When I clicked on the "Login" from the LastFM category, the "Login to LastFM" dialog comes up. I expected the app to rotate to landscape and back to portrait with the dialog, successfully without crashing.

Actual behavior

When I clicked on "Login" under LastFM which is in the Settings Activity, the "Login to LastFM" dialog comes up, when I rotate the screen to landscape it rotates successfully but on rotating it back to portrait view, the app crashes.

How to reproduce

• Download the app from play store
• Launch the app
• At the Home Activity, from the Nav drawer or from the Menu options, click on "Settings"
• In the "Settings" Activity, scroll down to LastFM category and Click on "Login"
• Dialog comes up, Rotate the screen to landscape
• Rotate it back to portrait view
• App crashes and Exit

• App Version : Version 1.6
• Device : Gionee A1 Lite
• Operating system: Android 7.0
