当我运行'build> rebuildproject'函数时发现了一个问题，但是当我运行'build> clean project'时，该问题的通知不存在，这使我无法在模拟器上运行该应用程序并收到通知出现“编译失败完成”。 发生错误通知：
Program type already present: android.support.v4.app.INotificationSideChannel
Message {kind = ERROR, text = Program type already present: android.support.v4.app.INotificationSideChannel, sources = [Unknown source file], tool name = Optional.of (D8)}
和
: app: transformDexArchieveWithExternalLibsDexMergeForDebug
Execute transform
