build - 构建 AndEngine 示例的 NDK 时出错

Question

我正在尝试在我的 MacOS Android Studio 2.3.2 上构建 AndEngine 示例。
但是得到这个错误。无法弄清楚是什么问题。奇怪的是，相同的项目通常在 Windows 上构建，相同版本的 Android Studio。

> FAILURE: Build failed with an exception.
What went wrong:
Execution failed for task ':andEngine:externalNativeBuildRelease'.
> Build command failed.

          ^

我的 Application.mk 文件:

# Build both ARMv5TE and ARMv7-A and x86 machine code.
APP_ABI := armeabi armeabi-v7a x86
APP_STL := gnustl_shared

和 Android.mk:

LOCAL_PATH:= $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE             := andengine_shared
LOCAL_MODULE_FILENAME    := libandengine
LOCAL_CFLAGS             := -Werror
LOCAL_SRC_FILES          := src/GLES20Fix.c \
                             src/BufferUtils.cpp
LOCAL_LDLIBS             := -lGLESv2
LOCAL_EXPORT_C_INCLUDES  := $(LOCAL_PATH)/src

include $(BUILD_SHARED_LIBRARY)

Android NDK: android-9 is unsupported. Using minimum supported version android-14.

添加 APP_PLATFORM := android-14在 Application.mk文件

如果您没有该行，那么您的 SDK 版本将从 project.properties 文件中获取。
