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？
