我曾尝试按照许多指南创建Android Native Activity，但我无法运行我的应用程序。相反，我从LogCat中获得以下内容：

我已阅读以下问题1和2，但这些都没有对我有所帮助。我粘贴在我徒劳的努力下面，希望有人能看到我不能做的事。
的AndroidManifest.xml：
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.bigdavedev.opengl"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="10"
android:targetSdkVersion="19" />
<application
android:allowBackup="true"
android:hasCode="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >
<activity
android:name="com.bigdavedev.opengl.MainActivity"
android:label="@string/app_name"
android:screenOrientation="landscape" >
<meta-data
android:name="android.app.lib"
android:value="@string/app_name" />
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
MainAcitivy.java：
package com.bigdavedev.opengl;
import android.app.NativeActivity;
import android.os.Bundle;
public class MainActivity extends NativeActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
}
}
Android.mk：
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := bigdavedev
LOCAL_SRC_FILES := main.cpp \
dave/application/application.cpp \
dave/core/kernel.cpp \
dave/platform/android.cpp
LOCAL_LDLIBS := -llog -landroid -lEGL -lGLESv2
LOCAL_STATIC_LIBRARIES := android_native_app_glue
include $(BUILD_SHARED_LIBRARY)
$(call import-module, android/native_app_glue)
Application.mk：
APP_PLATFORM := android-10
NDK_TOOLCHAIN_VERSION := 4.8
APP_STL := gnustl_shared
APP_CPPFLAGS := -std=c++11
最后，main.cpp：
#include <android_native_app_glue.h>
#include "dave/application/application.hpp"
extern "C"
{
void android_main(struct android_app* state)
{
app_dummy();
dave::application app(state);
if (app.initialise())
{
app.run();
}
}
}
此时，我确信我在没有意识到的情况下正盯着解决方案。
答案 0 :(得分：0)
事实证明，元数据标签需要看起来像：
<meta-data
android:name="android.app.lib_name"
android:value="@string/app_name" />
现在一切正常。
