[fixed]HelloWorld_Android crashes sometimes after resuming

[stoneageartisans]

I'm testing the HelloWorld_Android example on a mobile phone running Android 5.1.

Sometimes (but not always!) after going back into the HelloWorld_Android app after the HOME key was pressed it will crash with the following error message:

Unfortunately,
HelloWorldMobile has
stopped.

If I return to the app after the BACK key was pressed, this never happens. I made a simple "hello world" Irrlicht app and it has the same behavior.

I can't really find any mention via Google of apps using NativeActivity doing this exact thing after the HOME key is pressed, but from what I did see it seems like there are some issues in android_native_app_glue.

Thanks for any input.

Hm, yeah - I can reproduce it. Moving this one to bug-reports. Can't remember having that in the past, so maybe some newer bug.

Thanks for the report.

Thanks for looking into it.

Should be fixed now in svn (r5463). Looks to me like an accidentally introduced code change (but I'll check with author).

A storm Saturday night knocked out my power, phone, and internet. The latter was finally restored today. I will update my repo, rebuild, and test. Thanks!
