Hi @xyzz,

Thank you for your bug report.
I'm working on fixing the crash reported, but it appears that your application is using OpenGL ES 1.0 commands. Unfortunately GAPID currently only supports OpenGL ES 2.0 onwards, so even with the fix, GAPID will be of limited use for this particular app.

Many thanks,
Ben

Thanks for your reply.

Do you have a suggestion for a tool that's supported and can trace opengl es 1 commands on Android?

Do you have a suggestion for a tool that's supported and can trace opengl es 1 commands on Android?

I'm afraid not. We currently do not support OpenGL ES 1.x as all Android devices have supported OpenGL ES 2.0 since Android 2.2 (released 7 years ago) and there were major API breaking changes between OpenGL ES 1.x and 2.0. Supporting OpenGL ES 1.x would require significant work and we believe the significant majority of developers will be targeting OpenGL ES 2.0 onwards or Vulkan.

Sorry for the bad news!
