I am trying to get PVRTrace working on my Asus Memo Pad 7 which was not rooted. I was able to build and install my apk, and copy the pvrtraceconfig.json to /sdcard folder on my device. Debugging the the app shows that System.Load(“libPVRTrace.so”), etc, succeeds, and I get the following output: … [PVRTrace] Setting EglLibraryPath default to ‘/system/lib/libEGL.so’’ [PVRTrace] Setting Es1LibraryPath default to ‘/system/lib/libGLESv1.so’’ [PVRTrace] Setting EglLibraryPath default to ‘/system/lib/libGLESv2.so’’ … [Mono] DllImport loaded library ‘./libEGL.os’ … and so on The above three lines are the only indication that PVRTrace is part of my app. There are no errors; no other PVRTrace output. It is almost as if the config json file was ignored; and tracing never started. The pvrtracconfig.json is cut-and-paste from documentation (except that I changed the path of EglLibraryPath, etc, to actual libs on the device). Has anyone tested PVRTrace with Xamarin/OpenTK? Or am I doing something wrong? ---

Could you check in /data/local/tmp that a file exists named “pvrtrace\_enable” which has the contents “1”? Otherwise, send the logcat for the application loading. ---

I did add pvrtrace\_enable to /data/local/tmp; but it made no difference. I also tried to reply to the e-mail I received, but it bounced back with error "550 … User unknown" Here is the logcat output (from Release build): [monodroid-gc] GREF GC Threshold: 46800 [AndroidInfo] Load PVRTrace libraries [PVRTrace] Setting EglLibraryPath default to ‘/system/lib/libEGL.so’.
