ClassNotFoundException BootstrapApplication，android？

Question

每當我試圖運行我的應用程序，我得到這個錯誤。

我甚至禁用Instatn運行在工作室

禁用Android Studio中即時運行選項。說明在Android Studio Instant Run documentation.

即時運行試圖做你的代碼的熱交換;這會導致應用程序類被移動。

要禁用即時運行轉到

File --> Settings--> Build, Execution, Deployment --> Instant Run ---> uncheck "Enable instant run"
