Android Emulator不会在Eclipse中启动

我只是安装了整个shebang,以便在Eclipse中开发Android应用程序(我运行的是64位gentoo)。一切似乎都很顺利,我创建了Dev Group的Hello World示例:

package com.nfshost.flyingmonkey.android;

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);
        setContentView(R.layout.main);
        TextView tv = new TextView(this);
        tv.setText("Hello, Android");
        setContentView(tv);
    }
}

我尝试在Eclipse中运行它,根据控制台,它似乎可以工作:

只是,仿真器不会像向导说的那样出现在我的屏幕上( http://developer.android.com/guide/tutorials/hello-world.html#run )
