This one is not related to DoEvents.

It happens inside box2d: box2d_World_jniCreateBody.

This is the only information available.

When are you creating bodies?
I've found random crashes if I create/delete a body/joint outside the render event.

When are you creating bodies?
I've found random crashes if I create/delete a body/joint outside the render event.

in "LG_Update" and LG_Update is called in "LG_Render"

almost all bodies are created when i load the tilemap from a Code Module.
some bodies are created in game when i click on fire for example i create the swords or when the player jump on water i create the water drops or when you kill a skeleton i create the bones so all are created in LG_Render.

could it be related to OpenGL ES version 3.1??

could it be that the current LibGDX version is not supported by OpenGL v3.1?

i see that all crashes are from devices that uses OpenGL v3.1

 

[ilan]

when i look now on other apps that does not use libgdx or box2d and have the same weird crash log

they also have OpenGL ES version 3.1 and CPU make Qualcomm.

@Erel could it be that b4a doesnot support that hardware yet??

B4A doesn't do anything special with OpenGL.
The views hardware acceleration feature is handled by the OS.
