GUESS WHAT!!!!!! Last night I was thinking why the app worked from August 2017
to May 2018 with no problems, and then in June 2018, it would stop working. So I got
the idea that maybe something changed with B4A. So I've always saved old versions
of my project, by zipping up the whole project, every time I made a major change. So I
got the idea of unzipping an old project, and rather than re building it in B4A, I would
just take the old apk file, copy it to my tablet, and reinstall it. I did this with a version
from March 31, 2018. I just flew it, and it worked flawlessly!!!!!!!!! It's a little small for my
new tablet, which is 10" vs my old 8" nvidia shield. Of course, I can't make any changes
to it, because if I recompile it, it won't work. So something changed in B4A or my installation.

Might be related to targetSdkVersion in the manifest editor. Uninstall the existing app and change it to 22.

OK I'll try that. When did 8.3 come out? It was set at 19.

 

[DonManfred]

When did 8.3 come out?

v8.30 - June 12, 2018: https://www.b4x.com/android/forum/threads/b4a-v8-30-has-been-released.94044/

 

[shb777]

I changed it to 22, but it kept crashing. So I reinstalled the old app, and went outside and flew again. Telemetry stopped coming in once, but other than that it worked ok. maybe I need to reinstall B4A.

 

[shb777]

that's about the time I started having problems.

 

[Cableguy]

Also, if I remember correctly, the DJY Lib also changed at around that time

 

[Erel]

It is most probably not related to B4A version.

 

[shb777]

I compiled it with 8.0 and it still crashed

 

[Erel]

You previously wrote that it crashed during flight. The error you posted above looks like an error that can only happen when the app starts.

Yes the crash I posted the logs for was indoors, not in flight, but the app crashed outdoors too. But I never took off because the app crashed before home was set, and I don't take off until home is set.

 

[Erel]

Please upload the project that crashes at startup.

 

[shb777]

Please upload the project that crashes at startup.

this is from my old post, #28 I took my drone out for flight testing today. The new app was constantly crashing. So I installed drone mission, and it too was constantly crashing. I had found out previously that all the apps including drone mission crash after the drone is left on a minute or so.

So even your drone mission program was crashing when compiled on my B4A installation. So I think I should send you my project from 3-31-18, you can compile it on your system, and then send me back the apk and I will see if it runs OK. Then we will know if there's something wrong with my installation.

 

[Erel]

You need to check the logs right after the app crashes.

 

[shb777]

but what was crashing was your drone mission so you already have that.

i'm installing a new 8.3 on a different computer so i'll try that when it's finished.

 

[shb777]

after installing 8.3 on a different computer, i'm getting this error when compiling my app
