SIGSEGV on Android (legacy mode)

mbrezu · July 10, 2015, 5:11am

Hello,

I get a segfault in an Android application. It used to work in January. The only source code changes I’ve made are removing references to the Sound class in my custom GameActivity.java. I didn’t manage to isolate the problem.

Here’s a stacktrace that I get on an x86 emulator with -Dlegacy and -debug. Any idea what’s going on?

The fun part is that this happens right after starting the app, and it still happens if I change my Main.new to {} I found a __loadprim in Lib.hx in hxcpp, but I can’t figure out what’s going wrong (it apparently tries to throw an exception and crashes).

Thanks!

You can sometimes get more information by compiling with these flags:

<haxedef name="HXCPP_CHECK_POINTER" />
<haxedef name="HXCPP_STACK_LINE" />

singmajesty · July 10, 2015, 6:38pm

Could you try doing a clean build of a simple sample, like “DisplayingABitmap”, and see if that works for you?

singmajesty · July 10, 2015, 6:38pm

If you are not using the same Java classes, make sure it loads “lime-legacy” and not “lime”

mbrezu · July 10, 2015, 6:52pm

Hello again,

turns out it wasn’t my different Java classes, but Proguard

Let me show again a bit of the stacktrace:

W/System.err( 1904): java.lang.NoClassDefFoundError: org/haxe/extension/Extension
W/System.err( 1904): at org.haxe.lime.Lime.onResize(Native Method)

W/System.err( 1904): at java.lang.ClassLoader.loadClass(ClassLoader.java:501)
W/System.err( 1904): at java.lang.ClassLoader.loadClass(ClassLoader.java:461)

Worth checking out, right? After disabling Proguard in project.properties my app worked. After a couple rounds of Proguard whacamole I added this to my proguard config:

-keep class org.haxe.extension.Extension { *; }

Now everything works.

I guess a bit of error handling should be added when trying to get/use the Extension class. And for everybody else out there debugging a startup crash, try disabling Proguard

Thanks!

singmajesty · July 10, 2015, 6:53pm

Wow, interesting. Is there something we could to improve the default Android template to avoid this?

mbrezu · July 10, 2015, 7:07pm

Maybe the C++ code that tries to get/use Extension should do more error checking and maybe fail more gracefully? I’m just guessing here, my JNI-fu is pretty much non-existent and my knowledge of OpenFL extensions is completely non-existent, so I can’t tell how ‘graceful failure’ looks like because I don’t know the use cases.

singmajesty · July 10, 2015, 7:16pm

Are you using any extensions?

The only code I can find that references by name is from the extension project sample:

	#if (android && openfl)
	private static var ::extensionLowerCase::_sample_method_jni = JNI.createStaticMethod ("org.haxe.extension.::className::", "sampleMethod", "(I)I");
	#end

mbrezu · July 10, 2015, 7:21pm

Not intentionally

How can I tell?

I have this line in project.properties:

android.library.reference.1=deps/extension-api

But I’m not sure why (my guess is this was in the project.properties in the template when I made my copy for customization).

Thanks!

mbrezu · July 11, 2015, 5:41am

OK, so if I remove the deps/extension-api line the GameActivity.java file fails to compile (the stock parts, not my changes). So the line is not useless, even though I don’t use any extensions.
