使用gnustl_static构建。得到了：
'abs' was not declared in this scope
当尝试使用stlport构建时，我无法使用c ++ 11方法 这是我的Application.mk：
APP_ABI := armeabi-v7a
APP_STL := gnustl_static
APP_CPPFLAGS += -std=c++11 -w
APP_PLATFORM := android-19
APP_OPTIM := release
Android.mk：
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := ModuleName
LOCAL_LDLIBS := -lm -llog -landroid
LOCAL_C_INCLUDES := .......
LOCAL_SRC_FILES += .......
include $(BUILD_SHARED_LIBRARY)
