Android always crash with AIR 50.2.2.3: java.lang.ClassNotFoundException: Didn't find class "com.adobe.air.AIRFileUtils"
Our app crash on Android a second after startup with the following native error:

I have the same issue. My app crashes with 50.2.2.3 SDK; works well with previous version.
Hoping a fix soon...
Hello, I've tried the 50.2.2.4 version that was released this morning. Unfortunately, the issue remains for me : the app still crashes at startup...
@Nisaba are you able to collect a logcat trace please? You can do this with ADT e.g.
adt -deviceLog -platform android > log.txt
If you start that and then open the application so that it crashes, and then type "quit" (enter) - or you can ctrl-c a couple of times - then the log.txt should contain the details. This may be something else...!
thanks

Thanks @Nisaba - that looks like it's a native extension that's failing to register properly.. so a different error at least, but one that we'll need to investigate.
That's strange as there's not a lot of difference here that should affect things. Would you be okay if we took a look at the APK, if you're able to build an apk-debug version then we can hopefully (a) reproduce it here and (b) replace the libCore with our own version with extra debugging information in it.. plus we can analyse the APK assets to check the descriptor and ANEs all seem to be in order.
The error (judging by the crash location and code beforehand) may be happening if an ANE was requested to be registered but already was registered.. There was one change we made here which is in relation to Worker objects, where these now would register the extensions too in order to get the AS3 definitions, so perhaps it's that. Thinking about it, do you use any delay-loaded extensions? Although, no the crash is happening in the main content loading step, before executing any of your code, which means it's not about Workers...
Anyway - if you're able to upload the APK below, we can investigate further. https://transfer.harman.com/requests/v7kryNBlzq9e3LOAuYETU2
thanks
Thanks -> definitely something wrong with that ANE. It's got an extension XML file with:
<platform name="Android-ARM">
<applicationDeployment/>
</platform>
No native library or initializer or anything, and there's no .jar or .so file in there. So that's why it's failing... Assuming you don't actually need/use that ANE (or it would tell you at runtime it's not supported), then we can put a patch into the runtime to stop the crash from happening... but you could just remove it for now from your app descriptor file.
thanks
OK ! I removed this ANE : com.freshplanet.AirNetworkInfo And it works now. Thanks !
Anyway, maybe it would be interesting to fix this issue on the next SDK release.

Done :-)

Starting from AIR ~51.2.2.x I can observe similar errors in LogCat on application start. But in my case it don't cause crashes.
It happens with multiple different devices, different Android versions (maybe in all cases armv7 used?) with different applications (even every simple and without native extensions).
