一：問題
今天在 OPPO R15 上調(diào)試代碼鞭光，安裝后發(fā)現(xiàn)無法啟動。報錯如下

報錯的重點在 這里Caused by: java.lang.ClassNotFoundException: Didn't find class "com.banger.xiaowei.ui.BaseApplication" 就是找不到類泞遗。
二：解決問題
這是Android studio 的 instant run給我們留下的坑惰许。需要在Android studio 中設置下
-
Perferences
image - Build,Execution, Deployment
- instant run
-
Enable instant run to hot swap code/resouce changes on deploy(default enabled) ，默認這個是勾選的史辙，關閉這個功能汹买，即可正常運行調(diào)試 app 。
