刚在网上下载一个AndroidStudio,随便创建一个项目生成的Apk闪退;报以下错误:
java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{listview.chenmiaohui.com.mylistviewdemo/listview.chenmiaohui.com.mylistviewdemo.ListViewActivity}: java.lang.ClassNotFoundException: Didn't find class "listview.chenmiaohui.com.mylistviewdemo.ListViewActivity" on path: DexPathList[[zip file "/data/app/listview.chenmiaohui.com.mylistviewdemo-2/base.apk"],nativeLibraryDirectories=[/data/app/listview.chenmiaohui.com.mylistviewdemo-2/lib/arm64, /system/lib64, /vendor/lib64]]

大致翻译了一下，也就是运行时无法实例化。找了一大圈子都是Eclipsec处理办法，最后看了好多搜了好多试了很多种办法都无法实质性的解决问题。最后直接搜"生成apk闪退"还真找到了大神们的解决办法：
1.主要还是把Android Studio的Instant Run关闭即可！
File>settings>Build,Execution,Deployment>Instnt Run>Enable Instant Run to hot swap code点掉对勾保存
