android - 编译项目时出现 undefined reference 错误(ANDROID NDK)

Question

我在使用 Android NDK 时遇到了这个问题。我收到以下错误；

22:30:09 **** Incremental Build of configuration Default for project MrBlueFramework ****
"D:\\Android_Development\\Android_NDK\\ndk-build.cmd" all 
Android NDK: WARNING: APP_PLATFORM android-19 is larger than android:minSdkVersion 8 in ./AndroidManifest.xml

make.exe: *** [obj/local/armeabi/libMrBlueFramework.so] Error 1

这是我的层次结构；

这是我的android.mk

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := MrBlueFramework
LOCAL_SRC_FILES := MrBlueFramework.cpp \
                   Framework/Application/Application.cpp\
LOCAL_C_INCLUDES        := $(LOCAL_PATH)
LOCAL_LDLIBS    := -llog -landroid -lEGL -lGLESv2
LOCAL_STATIC_LIBRARIES := android_native_app_glue

include $(BUILD_SHARED_LIBRARY)
$(call import-module,android/native_app_glue)

这里是Application.h的内容

#include <android_native_app_glue.h>

namespace Framework
{
    class Application
    {
    private:

    public:
        Application(android_app *state);
        virtual ~Application();

        bool Initialize();
        void Run();

    };
}

这是主类 (mrblueframework.cpp)

#include <jni.h>
#include <android_native_app_glue.h>
#include "Framework\Application\Application.h"

using namespace Framework;

void android_main(android_app *state)
{
    app_dummy();

    Application app(state);
}

我不明白我做错了什么，我在顶部包含了我的 Application.h 文件，但仍然找不到它。请帮我解决这个问题。

Answer 1

LOCAL_SRC_FILES := MrBlueFramework.cpp

Application.cpp 不存在。
