java - Android 模拟器没有响应程序

Question

好的，伙计们，我决定尝试这个开发人员的东西，在大约十二个教程之后，最终得到了以下 Hello World 类型的程序:

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);}
}

很简单，所以我去编译它，我得到了这个

[2011-03-14 00:11:25 - HelloAndroid] Android Launch!

[2011-03-14 00:11:25 - HelloAndroid] adb is running normally.

[2011-03-14 00:11:25 - HelloAndroid] Performing com.example.helloandroid.HelloAndroid activity launch

[2011-03-14 00:11:25 - HelloAndroid] Automatic Target Mode: launching new emulator with compatible AVD 'my_avd'

[2011-03-14 00:11:25 - HelloAndroid] Launching a new emulator with Virtual Device 'my_avd'

[2011-03-14 00:11:30 - HelloAndroid] New emulator found: emulator-5554

[2011-03-14 00:11:30 - HelloAndroid] Waiting for HOME ('android.process.acore') to be launched...

或者如果我已经启动了模拟器，我会得到这个

[2011-03-14 08:23:09 - HelloAndroid] Android Launch!

[2011-03-14 08:23:09 - HelloAndroid] adb is running normally.

[2011-03-14 08:23:09 - HelloAndroid] Performing com.example.helloandroid.HelloAndroid activity launch

[2011-03-14 08:23:09 - HelloAndroid] WARNING: Application does not specify an API level requirement!

然后模拟器每次都会出现这个空白屏幕，上面有文字“android”。它在那里坐了大约 3 分钟，直到它进入另一个空白的黑色屏幕，除了它的动画之外还有“android”。我环顾四周，似乎找不到任何有同样问题的人。就像模拟器甚至无法识别我正在做的任何事情一样。这是空白虚无的漂亮屏幕截图:

那么，你知道我哪里做错了吗？

尝试等待模拟器加载所有内容，然后再启动您的应用。
