我已經搜索瞭解決方案，並且有幾個和SO類似的ClassNotFoundException線程。但我嘗試瞭解決方案，沒有任何幫助。所以在我的情況下，直接從Android Studio將應用程序部署到設備時，它運行正常，但從文件安裝時崩潰：adb install app-debug.apk。路徑中未找到.MyApp類：DexPathList。只有在直接運行debug apk的情況下

我有在項目類MyApp的。那個日誌對我來說沒有任何意義。在將Android Studio更新到2.3並更新項目中的某些依賴項後，我發現了這個問題。在它工作正常之前。
我將不勝感激任何幫助解決這個問題。
編輯： 經過一些試驗後，我發現我創建構建的方式有所不同。如果我使用Build/Build APK和adb install app-debug.apk構建我的項目，它不會拋出異常。但每次我使用運行/運行「應用程序」選項將應用程序部署到設備時，安裝apk通過終端結果以這種方式創建的方式與上述異常崩潰。它是打算行爲還是錯誤？
另外值得注意的是，Build/Clean項目修復了下一個版本的問題。
