Gradle build-info.xml not found for module app.Please make sure that you are using gradle plugin '2.0.0-alpha4' or higher.

解决方法：去掉“Enable Instant run to host swap code/resource changes on deploy(default enabled)”的勾选项



Settings→Build→Instant Run:

1：Enable Instant Run to hot swap code/resource changes on deploy (default enabled)

//启用即时运行 热交换代码/资源变化 部署(默认启用)

2：Restart activity on code changes

//当代码变动时重启

3：Show toasts in the running app when changes are applied

//当代码变动应用时弹出toast

4：show Instant Run status notifications

//在notification里显示instant Run 的状态

当再次勾选后出现了新问题
The APK file D:\Android\del\MaterialDemo\app\build\outputs\apk\app-debug.apk does not exist on disk.
Error while Installing APK

解决方案：build-->build apk
