Android的工作室：应用程序安装失败 [英] Android Studio: Application Installation Failed

问题描述

我一直在努力学习如何使用Android工作室，但是当我试图运行示例程序我得到这个错误消息之一：

I've been trying to learn how to use Android Studio but when I attempted to run one of the sample programs I get this error message:

Installation failed with message null.
It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.

WARNING: Uninstalling will remove the application data!

Do you want to uninstall the existing application?

我试图做到这一点的5个样本程序和所有的人给我这个错误。有谁知道如何解决此问题？

I've tried to do this on 5 more sample programs and all of them give me this error. Does anyone know how to solve this?

从AVD卸载为我工作。重新安装后，它的工作

Uninstalling from AVD worked for me. After reinstalling it worked
