Resolved Mobile App crashes on startup in Android Studio 3.6.1

I am trying to publish my PB Mobile App on Android for the first time.

The package has been created and opened in Android Studio (Ver. 3.6.1).

I have made the changes to the SDK settings as per the instruction in PB Powerserver Help files.

The APK has been created and posted to Google Play but still awaiting approval (CoronaV is delaying things).

When I try to run the Build from Android Studio on any device (so far tested Pixel 2 API R & Nexus 5X API) the application starts to launch but all I see is a big large white window with the Appeon logo on the top left.

Then it shuts down immediately before anything else.

Here is the error log:

2020-03-20 08:07:44.071 11477-11477/com.dct.microstaffer E/AndroidRuntime: FATAL EXCEPTION: main

NOTE: I already published this app on IOS in Apple Store/Test Flight and it works perfectly 100% on all IOS so far.

I tried to Google libEonAmp.so but found nothing.

Below is the brief image of the app in the simulator just before it crashes.

Again, all works in IOS just not in Android.

Any help is appreciated.

Hi Richard;

You seem to be very current, so this problem seems strange. I would suggest creating a Support Ticket for this problem.

Hi Richard;

   Are you using an Android "simulator" or real device(s)?

Hi, I just the new update on my note 30 ultra, and now the app won't load. It starts up but then immediately crashes. Any ideas?

Hi Richard;

Thanks for the feedback. Yes, I have seen other developers with the same situation. The simulator does not work with your PS Mobile App but, it does on actual devices. However, it not untypical that "simple" Apps do work on the simulators.

Hi Richard,

Did you package a 64-bit APK and then run it on 64-bit Android OS? Please check if the file libEonAmp.so exists in paths below:
%package%\libs\arm64-v8a
%package%\libs\x86_64

The application might not work well on Simulator which generally is an x86 architecture. So we recomand you to test it on a real Android device which generally is an ARM architecture.

It seems you had reported same issue on ticket #4291, please refer to it for details.

Regards,
ZhaoKai
