App crash when screen is rotated during a Folder Compress Operation

Expected behavior

I expected the operation to continue even during external operations like a screen rotation. As one may have a need to use a different orientation while this is ongoing.

Actual behavior

The App crashes or force closes it self when a folder is being compressed and the screen is rotated.

How to reproduce

• set the device to automatic rotate screen.
• Launch amaze file manager.
• Choose a folder which has contents
• long press on the folder to select it
• click on a three vertical dots that will appear at the top right corner.
• choose compress from the menu.
• wait for the operation to start
• Then rotate your device, for the view screen to change orientation.

Testing Environment

• Browser: Chrome
• Operating system: Android Version 6.0, Marshmallow.
• App Version: v3.2.1
• Device detail: Itel P12
