重新安装，由于不同的应用程序签名失败 [英] Re-installation failed due to different application signatures

问题描述

我把我的Andr​​oid项目，以一台笔记本电脑，现在我得到这个，当我打调试。听起来这是一个错误？这不应该通过Eclipse发生，因为据我所知。

I moved my Android project to a laptop and now I get this when I hit Debug. Sounds like this is a bug? This shouldn't happen via Eclipse as far as I know.

Re-installation failed due to different application signatures.

最奇怪的是这件事发生后，我升级SDK / ADT和Eclipse支持SDK 2.2 这是工作的罚款较早，现在没有，所以它可能是一个错误。

The weirdest thing is this happened after I upgraded sdk/adt and Eclipse to support SDK 2.2 It was working fine earlier, and now it doesn't, so it might be a bug.

推荐答案

这是因为你的笔记本电脑和最初的PC密钥库是不同的。这就是所谓的debug.keystrore 而位于％USER_HOME％/。安卓/ 文件夹。更具体地它发生因为蚀试图推动的apk与重装键。所以，你有两个选择

It happens because keystores on your laptop and original pc are different. it's called debug.keystrore and located in %USER_HOME%/.android/ folder. TO be more specific it happens because eclipse tries to push apk with reinstall key. So you have two options

1. 分享各种开发PC的
之间debug.keystore
2. 手动从设备卸载APK（使用ADB）

1. Share debug.keystore between various development pc's
2. Manually uninstall your apk from device ( using adb )
