嘗試在Android Studio中運行項目時，InstantRunNotificationTask中的NullPointerException

Question

每當我運行帶有這些細節的項目時，我在Android Studio中收到錯誤：

我已經嘗試重新安裝SDK，插件並重新啟動所有內容。 不確定還有什么可能出錯。

Answer 1

• 轉到Preferences 。
• 然后在Build, Execution, Deployment部分下Build, Execution, Deployment您將擁有Instant Run部分。
• 取消選中 “ Enable Instant Run...復選框，然后再次嘗試構建項目。
