java.lang.RuntimeException:无法实例化活动ComponentInfo {}:java.lang.ClassNotFoundException

Question

我正在尝试使用cordova构建一个HelloWorld android应用程序.我正在关注以下网页上提到的脚步 http://javaonlineguide.net/2015/06/apache-cordova-hello-world-program-for-android-platform-in-eclipse-example.html

我一直在浏览这个问题,我很确定我没有提到的问题.我的两个活动都在AndroidManifest中声明,而intent过滤器就在那里.我尝试用.MainActivity替换我的Manifest com.example.main.MainActivity,但仍然没有运气.我正在使用Eclipse IDE在Java构建路径中 - > Order and Export Android Private Libraries已经过检查

我一次又一次地尝试建造和清洁项目.我甚至尝试重启Eclipse.

这是Logcat:

这是AndroidManifest.xml:

<?xml version='1.0' encoding='utf-8'?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.main"
android:hardwareAccelerated="true"
android:versionCode="1"
android:versionName="0.0.1" >

<supports-screens
    android:anyDensity="true"
    android:largeScreens="true"
    android:normalScreens="true"
    android:resizeable="true"
    android:smallScreens="true"
    android:xlargeScreens="true" />

<uses-permission android:name="android.permission.INTERNET" />

<application
    android:hardwareAccelerated="true"
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    android:supportsRtl="true" >
    <activity
        android:name="MainActivity"
           android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale"
        android:label="@string/activity_name"
        android:launchMode="singleTop"
        android:theme="@android:style/Theme.DeviceDefault.NoActionBar"
        android:windowSoftInputMode="adjustResize" >
        <intent-filter android:label="@string/launcher_name" >
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

<uses-sdk
    android:minSdkVersion="14"
    android:targetSdkVersion="23" />

</manifest>

这是MainActivity.java

package com.example.main;

import android.os.Bundle;
import org.apache.cordova.*;

public class MainActivity extends CordovaActivity
{
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        // Set by <content src="index.html" /> in config.xml
        loadUrl(launchUrl);
    }
}
