The game crashes and returns to the OS launcher when attempting to switch the storage location of a world from Application to External.

To reproduce this problem:

1. Begin playing in a Survival world that is currently using the application storage
2. Pause the game, then choose Settings -> Profile
3. Switch "File Storage Location" from "Application" to "External"

At this point the "File Storage Location" list will say "External" and will remain green, indicating it is the active widget, for approximately 3 seconds. During this time the game appears to be frozen. Then the widget will return to the normal "black on gray" colors, but the game is still unresponsive. It will stay this way for approximately 1 second, then the game will exit and return to the Android launcher/home screen.

The attached screenshots are of the settings screen before selecting "File Storage Location", after switching to "External" while still green, and after switching to "External" once the widget has returned to normal.
