Only White Screen

[deshan]

Thanks for the project and nice tutorial!

When I run the project I see only a white screen. Any ideas?

Thanks

Hi deshan, can you upload the logcat? It is probably failing to create a GL window but I need to check the logs to confirm.

Thanks for the reply.

This is the log

Thanks for sending the log. This is only a portion of it and indicates that none of GLES operations are working correctly. Please upload the logs from the beginning so that we can check if a GLES instance was created correctly. Also let me know your device model.

Thanks for sending the log. This issue was because the fragment shader was missing the precision qualifier for float. I've added it and it should work now. Please let me know if you see other issues.

Great Application works fine
