My OpenFL app crashs on android very often, the crash looks occurring randomly.

In logcat, the log is something like "09-05 23:53:52.264 F/libc ( 9556): Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1), thread 9667 (Thread-7328)" following by lot's of hex addresses, in which I cannot locate the root cause at all.

My environment:

WinXP

Haxe 3

Android NDK r8c

hxcpp: 3.0.2 haxelib version

nme: git version

openfl-native: git version

Android devices: Samsung GT-I9268 (4.1.2), Huawei C8813Q (4.1.2), MI-ONE Plus (2.3.5)

Here's a typical crash output of the debug build of my app.

Though the below crash shows it occurs during the jpg encoding, however it's not crash everytime in the very location, and crash also occurs elsewhere:

This has affected us too. It tends to happen less in release build with fewer logs... I would advise you do what we had delayed. Put up with an open source sample demonstrating the issue and publish it.

Good luck :)

Looks like a HxCPP Garbage Collector related problem. Not sure if Hugh
has fixed some of them recently or not.

Best,

By any chance you are not using HaxeObject in your project? I refer to this bug: https://haxenme.atlassian.net/browse/NME-252

Seems to me that this bug is related with the hxcpp collector being called from a different thread (e.g. Android's main UI thread)

AFAIK, hxcpp needs that all threads that may call the GC to be registered.

You can probably force a more "reliable" crash by calling cpp.vm.Gc.collect(true) inside the function that is being called through Java

Also to help debugging JNI problems try compiling using a newer target SDK, so you dont see this "Turning on JNI app bug workarounds for target SDK version 5..." in the log.

Yes I was using a worker thread to do jpeg encoding, however I don't do any explicit GC call in my code, are there any API cause implicit GC collection?
