1、编写Android.mk
#x264
include $(CLEAR_VARS)
LOCAL_MODULE := x264
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/x264/include
LOCAL_SRC_FILES := libs/libx264.a
$(info $(LOCAL_SRC_FILES))
include $(PREBUILT_STATIC_LIBRARY)2、编写Application.mk
APP_ABI := armeabi
APP_PLATFORM := android-19
APP_STL := gnustl_static3、遇到的坑
1、报错
