Android Eclipse 无法连接到模拟器上的活动管理器 - HelloWorld 未出现

Eclipse can't connect to activity manager on emulator - HelloWorld does not appear

提问by Andy P.

This appears related to: Android application doesn't start from Eclipse

这似乎与： Android 应用程序不从 Eclipse 启动

Even with the Android 2.2 platform is this still the accepted way to operate the emulator? i.e. 1, 2, 3 start/kill processes as described in the above post? I am having a similar problem on WinXP with Eclipse w/ ADT plugin. Why would the activity not be able to start on the emulator? The computer has 756MB RAM if that could be the problem. The deployment is going along until Eclipse tries to deploy the activity. The emulator starts with the text "ANDROID_" and then eventually just displays the ANDROID logo, though appears to still be running just fine. Any ideas? Thanks. The code was copied from the HelloWorld tutorial. Here is the Eclipse console log including the error messages towards the end:

即使使用 Android 2.2 平台，这仍然是运行模拟器的公认方式吗？即 1、2、3 个启动/终止进程，如上述帖子中所述？我在带有 ADT 插件的 Eclipse 的 WinXP 上遇到了类似的问题。为什么活动无法在模拟器上启动？如果这可能是问题所在，计算机有 756MB RAM。部署会一直进行，直到 Eclipse 尝试部署活动。模拟器以文本“ANDROID_”开头，然后最终只显示 ANDROID 徽标，但似乎仍然运行良好。有任何想法吗？谢谢。该代码是从 HelloWorld 教程中复制的。这是 Eclipse 控制台日志，包括最后的错误消息：

Go to a command prompt and run these commands:

转到命令提示符并运行以下命令：

adb kill-server

Now run the emulator and then your application using:

现在运行模拟器，然后使用以下命令运行您的应用程序：

adb install -r myApp.apk

This solved my problem

这解决了我的问题

Hi Andy what are the complete specs of your computer I have experienced the same when i tried to run any code in a slow computer.

嗨，安迪，你的计算机的完整规格是什么？当我尝试在慢速计算机上运行任何代码时，我也遇到过同样的情况。

You have to wait some minutes until the emulator has loaded. Then start application again.

您必须等待几分钟，直到模拟器加载完毕。然后再次启动应用程序。
