Question

我正在尝试启动我的Android应用程序。不幸的是，通过删除主要活动并弄清楚清单，我搞砸了一下。

我试图让应用程序首先启动我的菜单活动，我想我不需要主要的活动。这是清单

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

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="18" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.example.taekwondobuddy.Menu"
        android:configChanges="orientation|keyboardHidden|screenSize"
        android:label="@string/app_name"
        android:theme="@style/FullscreenTheme" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

</manifest>

这里是菜单类，即使我认为它是不必要的

       package com.example.taekwondobuddy.util;        
      import android.app.ListActivity;
     import android.content.Intent;
     import android.os.Bundle;
      import android.view.View;
    import android.widget.ArrayAdapter;
     import android.widget.ListView;

    public class Menu extends ListActivity {

String classes[] = {"Tool","Techniques","Tkd Buddy"} ;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setListAdapter(new ArrayAdapter<String>(Menu.this, android.R.layout.simple_list_item_1, classes));
}


@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    // TODO Auto-generated method stub
    super.onListItemClick(l, v, position, id);
    String cheese = classes[position];
    try{
    Class ourclass = Class.forName("com.example.taekwondobuddy" + cheese);
    Intent ourIntent = new Intent(Menu.this, ourclass);
    startActivity(ourIntent);
    } catch(ClassNotFoundException e){
        e.printStackTrace();

    }
}




  }

控制台也注意到了

并且它将运行应用程序，但告诉我应用程序已意外停止

我认为清单中的内容是，它是否正在尝试找到我删除的主要活动类，如果它是如何创建它以便此菜单类将成为我的新主要活动？

Android应用无法启动启动器
