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 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:

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 12:57:35 - HelloWorld] ------------------------------

如何解决这些问题以便我的应用程序能够启动?

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

推荐答案

尝试更改 ADB 连接超时.我认为它默认为 5000 毫秒，我将我的更改为 10000 毫秒以解决该问题.如果您在 Eclipse 中，您可以通过 Window -> Preferences 然后在 Android 下的 DDMS 中执行此操作.

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.

如此处所述:Android 错误:无法安装 *设备上的.apk *:超时
