Hi all,

I am trying to get some trace with PVRTrace in **Android 4.03** with **TI OMAP4430** platform.

By following the&nbsp;instruction&nbsp;of the PVRTrace User Manual, the application can show with these PVRTrace library.

The logcat &nbsp;shows that these SO library have been loaded, but I found a lot of error about **"eglGetProcAddress Extension Error"**.

I have tried network/offline recording but got similar error.

Anyone can give me some suggestions about this error?

Many thanks for your help.

  

Best Regards,

Richard

Hi Richard Lu,

If you are not using that extension in your application you don't have anything to worry.&nbsp;

We have change the message "error" for "warning" as in the Android Java Layer who asks for all that extension by default.

And just to let you know, next week we are going to release a new version of PVRTrace 3.0 Revision 2 with a few issues fixed.

Regards,

David
