SIGSEGV Error JNI exception at UnityPlayer nativeRender

esdin · July 20, 2011, 1:29pm

Currently in the process of moving one of our iOS titles over to Android, and have spent the last few hours trying to figure out a nasty startup crash.

The Unity VM start without a hitch, and the loading scene successfully loads and runs. We also seem to be getting through at least the first update, as several debug logs manage to make their way through. Earlier, I was testing with a Droid, which indicated a segmentation fault but supplied no backtrace. Thankfully, a second device was able to give me the following:

W/dalvikvm( 3123): JNI WARNING: JNI method called with exception raised

An earlier version of the application had been able to without any errors, but that build was several months ago and a large number of changes have been made. I’ll continue to explore the problem on my end, and if I find the solution will post, but if anyone has any insight into the matter help would be greatly appreciated.

Additional Details:
-The project is using prime31’s GameCenter, Social Media, Etcetera, and Native Toolkit plugins for the iOS build. In addition to the existing Application.platform checks, I have added platform specific compilation definitions to all functions

-All files are #pragma strict.

I’m curious as to whether this could be an issue with the shader I use for crossfading between our game themes:

Shader "Simple Blending" {
	Properties {
		_MainTex ("Base (RGB)", 2D) = "white" {}
		_BlendTex ("Base (RGB)", 2D) = "white" {}
		_Color ("Color", Color) = (1,1,1,1)
		_BlendColor ("BlendColor", Color) = (1,1,1,0)
	}
	 SubShader {
        Tags { "Queue" = "Transparent" }
		Pass
		{
			Blend SrcAlpha OneMinusSrcAlpha
			Color[_BlendColor]
			SetTexture[_MainTex]
			{
				constantColor[_Color]
				combine texture * constant
			}
            SetTexture [_BlendTex] 
            { 
            	combine texture lerp(primary) previous
            }
        }
    }
	FallBack "Diffuse"
}

edit: Changed it to a standard transparent and the error is still occurring.

Went through and #pragma strict’ed everything to see if that was the issue, but still receiving the fault.
Here’s some more data and the stack from adb DEBUG:

Solved!
An integer value was stored as a float in the PlayerPreferences file.
