Android Question java.lang.NoSuchFieldException:

Hi,

the sub "GPS1_GpsStatus" in the starter service produces a crash, what could be the trigger?

Never load an image file more than once. Load them when your program starts in Service_Create.

It doesn't look that your code was compiled with the latest version of B4A. Did you make an update to your app with B4A v8?

Thanks, that's a good tip.

I compiled it with version 7.81, because version 8.0 did not exist at that time.

Please try it with B4A v8.0. If it happens again then hopefully it will be easier to analyze the crash report.
