Exporting images caused a crash.

[YYYSSSHHH]

Environment Info：
APK Version: 1.2.0 (9)
Android simulator version: 6.0.1

Repro Steps：

Revoke storage permission of app in the background.
1.Click the Navigation button in the top right-hand corner of app and then click the Export button.
2.Click any button in the box，namely PNG , GIF and Sprite Atlas.
3.Size is set at 40 × 40 .
4.Click the EXPORT button, then the app will crash.

I believe the APIs for checking(checkSelfPermission)/asking(requestPermissions) storage permission should get called.

Do you judge this as a defect?

• Well, I cant say that this is "unexpected" app behavior sinсe user knows what caused it and application will request permissions on next restart anyway
• Also it seems like this problem only affects old(<API29) versions of Android.

As a "workaround" I can save project before exporting to prevent loss of changes to the project

Ok. Maybe the Android version of my simulator is too low. In a word, thank you for your reply！
