I'm trying to implement a dashbord in android studio from this tutorial https://www.youtube.com/watch?v=d6CfaWW7G5Q&feature=youtu.be I did exactely the same things just replaced the home activity by main activity but When I run the app, it's successfully installed but it doesn't start and I get this as Error:
Gradle build finished in 10 s 569 ms
Install successfully finished in 41 s 368 ms.
Emulator: emulator: INFO: QtLogger.cpp:68: Critical: Uncaught TypeError: Cannot read property 'update' of undefined (qrc:/html/js/location-mock-web-channel.js:130, (null))
Emulator: Process finished with exit code 0
