.apk上传成功，但在ClassNotFoundException中启动意图结果com.game.demo.helloworld

我使用Cocos2dx库设置Eclipse IDE。我试图在cocos2dx库中设置并运行helloworld项目，但是在helloworld.apk成功上传到模拟器后，我在LogCat中遇到此错误。.apk上传成功，但在ClassNotFoundException中启动意图结果com.game.demo.helloworld

我在SDK 17 Eclipse构建：v22.0.1-685705

我已经通过计算器上几乎4-5类似的帖子看了，但已经尝试一切，不知道如何解决这个问题。

这里的logcat的条目：

这里是我的AndroidManifest.xml文件：

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
     package="com.game.demo" 
     android:versionCode="1" 
     android:versionName="1.0"> 

    <uses-sdk android:minSdkVersion="8"/> 
    <uses-feature android:glEsVersion="0x00020000" /> 

    <application android:label="@string/app_name" 
     android:icon="@drawable/icon"> 

     <activity android:name=".helloworld" 
        android:label="@string/app_name"

邮政helloworld.java（一个开始'package'）在helloworld.java –

第一行是第一行：包com.game.demo.helloworld;这与AndroidManifest.xml中的android：name标签值相匹配。但我认为我只是错误地引用了软件包？让我更新该项目的屏幕截图...也许这将有助于... – user2518312

我没有足够的分数来添加屏幕截图。 – user2518312

我刚做了一个类似的错误，昨天还没有与上所提供的所有答案的成功。我终于找到了：

我在代码中的任何地方都使用了“ViewPager”。

但是，在使用过的.xml文件中，我偶然输入了“viewPager” - 当然那个找不到。

另外，正如我今天发现的那样，如果有的话，请仔细检查您在.xml中使用的对象的包名。

你用apk输出了cocos2dx jar吗？如果不是这样，它会编译，但会崩溃。

您的清单包被声明为com.game.demo，但您的文件位于com.game.demo.helloworld。

尝试：

<activity android:name="com.game.demo.helloworld.helloworld"
