Android无法在设备上安装HelloWorld.apk（null）错误 [英] Android Failed to install HelloWorld.apk on device (null) Error

问题描述

我是Android的新手。当我在eclipse中运行我的Android应用程序时，我在控制台中收到这些消息：

  [2011-03-08 12： 57:35  -  HelloWorld] ------------------------------ 
 [2011-03-08 12:57： 35  -  HelloWorld] Android发布！

 [2011-03-08 13:02:22  -  HelloWorld]（null）
 [2011-03-08 13:02:23  -  HelloWorld]启动取消！ 
  

如何解决问题，以便我的应用程序启动？

解决方案

尝试更改ADB连接超时。我认为它默认为5000ms，我将我更改为10000ms以摆脱这个问题。如果您在Eclipse中，您可以通过Window - > Preferences进行操作，然后在Android下的DDMS中。

如下所述：Android错误：无法在设备上安装* .apk *：超时

I am new to Android. When I am running my android application in eclipse I am getting these messages in the console:

[2011-03-08 13:02:23 - HelloWorld] Launch canceled!

How do I resolve the problems so that my application will launch?

解决方案

Try changing the ADB connection timeout. I think it defaults that to 5000ms and I changed mine to 10000ms to get rid of that problem. If you are in Eclipse, you can do this by going through Window -> Preferences and then it is in DDMS under Android.
