I was trying to build the code which uses GraphicBuffer with ndk-r9d. but It is saying GraphicBuffer is not declared in this scope. The same comments for eglCreateImageKHR and glEGLImageTargetTexture2DOES. I have added EGL/eglext.h and GLES2/gl2ext.h . I tried to include ui/GraphicBuffer.h but it is not taking it. Is there another header file to be added ? The code given below I have added to avoid use of glTexSubImage2D(

I put the asset_test.txt file in my assets directory, and I looked in the .apk to make sure it exists by renaming the .apk to .zip and opening it with 7zip. I have some more code: AAssetDir* pAssetDir = AAssetManager

I know I can configure Application.mk in the following way to compile the source code for different chip set: APP_ABI := all This will trigger Android-NDK's build script to compile the source code for all the chipsets. However, I want to dynamically tell Android.mk to look for different static library dependencies compiled with different chip set. # Get the architecture info ARCH := ???? include $(CLEAR_VARS) LOCAL

编译的时候，总是提示SkImageDecoder.h头文件出错， 就是要更新一下依赖库， 然后重新 python tools / git - sync - deps后 重新编译bin\gn.exe gen out/armv7 --args="is_debug=false ndk=\"E:/android/android-ndk-r16b\" target_cpu=\"arm\"" 然后ninja -C out\armv7即可。 文章来源: skia android编译错误解决
