Hello Android意外地停止了

我已经在互联网上搜索了几天，并找到了几十种解决方案，但都没有。所以我想我会发布我的情况：

我已经在我的笔记本电脑上安装了eclipse和2.3.3 android SDK，将代码放入hello world（或hello android）并点击运行。模拟器启动，但是当活动运行时，我收到消息“SORRY！应用程序Hello Android（进程com.example helloandroid）意外停止。请再试一次”

package com.example.helloandroid;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class HelloAndroid extends Activity {
   /** Called when the activity is first created. */
   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       TextView tv = new TextView(this);
       tv.setText("Hello, Android");
       setContentView(tv);
   }
}

这是log cat

答案 0 :(得分：0)

您的模拟器的设置方式似乎有问题。您是否遵循此tutorial特别是“设置AVD”部分？

我会重新开始安装模拟器。您也可以向他发送一份程序副本，如果他能在模拟器中成功运行您的项目，那么您就知道您只需要正确设置您的模拟器。
