MainMenu.java

package com.demo;
import android.app.Activity;
import android.os.Bundle;
public class MainMenu extends Activity{

    @Override
    protected void onCreate(Bundle savedInstanceState) {        
        super.onCreate(savedInstanceState);
        this.setContentView(R.layout.main);
    }

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.splash);

        Thread splashTimer=new Thread()
        {
            public void run(){
                try{
                    //wait loop
                    long ms=0;
                    while(m_bSplashActive && ms<m_dwSplashTime){

                    startActivity(new Intent("com.google.app.splashy.CLEARSPLASH"));
                }
                catch(Exception ex){
                    Log.e("Splash",ex.getMessage());

    }

    @Override

    @Override

    }

    @Override

AndroidManifest.xml  这里面配置很重要

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.demo"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
    
<activity android:name="test" android:label="@string/app_name">
<intent-filter>
  <action android:name="android.intent.action.MAIN" /> 
  <category android:name="android.intent.category.LAUNCHER" /> 
  </intent-filter>
  </activity>

  <activity android:name=".MainMenu" android:label="@string/app_name">
 <intent-filter>
  <action android:name="com.google.app.splashy.CLEARSPLASH" /> 
  <category android:name="android.intent.category.DEFAULT" /> 
  </intent-filter>
  </activity>
  

    </application>


</manifest>
