我目前正在开展一个项目,我必须使用纯粹的原生ndk.当我尝试从Irrlicht引擎源运行helloworld示例时,它工作正常.然后我尝试在我的项目中使用它,遵循该示例的相同格式.但我得到了:

03-14 01:40:05.308: E/AndroidRuntime(799): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.irrlicht.example1/android.app.POMActivity}: java.lang.ClassNotFoundException: Didn't find class "android.app.POMActivity" on path: DexPathList[[zip file "/data/app/com.irrlicht.example1-2.apk"],nativeLibraryDirectories=[/data/app-lib/com.irrlicht.example1-2, /system/lib]]

在运行我的项目时.

这是我的main.cpp文件:

#include <android/log.h>
#include <jni.h>
#include <android_native_app_glue.h>
#include "android_tools.h"
#ifdef _IRR_ANDROID_PLATFORM_
void android_main(android_app* app)
{
__android_log_print(4 , "pom" , "nothing");
}

#万一

在Android.mk中:

LOCAL_PATH := $(call my-dir)/..
IRRLICHT_PROJECT_PATH := $(LOCAL_PATH)
include $(CLEAR_VARS)
LOCAL_MODULE := Irrlicht
LOCAL_SRC_FILES := /home/karthik/Android/Essentials/ogl-es/lib/Android/libIrrlicht.a
include $(PREBUILT_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := HelloWorldMobile1
LOCAL_CFLAGS := -D_IRR_ANDROID_PLATFORM_ -pipe -fno-exceptions -fno-rtti -fstrict-aliasing
LOCAL_C_INCLUDES := -I ../../include -I /home/karthik/Android/Essentials/ogl-es/include …

我只在棒棒糖版本上遇到这个问题.我可以在棒棒糖上面的版本上轻松运行应用程序.我在应用程序文件中运行应用程序时出现错误:
