1 This directory contains Android-side modules related to hardware OpenGL ES 2 emulation. The host-side modules and documentation are in 3 $ANDROID_BUILD_TOP/sdk/emulator/opengl. 4 5 Note that this directory contains encoder sources that are auto-generated 6 with the 'emugen' host tool (see sdk/emulator/opengl/host/tools/emugen). 7 8 To regenerate them, run external/qemu/distrib/update-emugl-sources.sh, 9 after building the emulator from sources, this will populate the content 10 here with the appropriate updated source files. 11 12 You should do this whenever you update one of the *.types, *.in and *.attrib 13 files located under one of: 14 15 $AOSP/sdk/emulator/opengl/libs/GLESv1_dec/ 16 $AOSP/sdk/emulator/opengl/libs/GLESv2_dec/ 17 $AOSP/sdk/emulator/opengl/libs/renderControl_dec/ 18 19 or when the 'emugen' tool itself is modified. 20
