Affected Device(s) [e.g. Samsung Galaxy s10 with Android 9.0] Answer︰HTC U11 with Android 9.0

Describe the Bug: Add a clear description about the problem. Answer︰ForecastsViewModel中的viewModelScope.launch()的block()不會被調用，下圖中的紅框內容不會被調用。 2020-01-17_002021

Expected Behavior: A clear description of what you expected to happen. Answer︰點擊Show Forecasts按鈕後，跳轉至ForecastsFragment。然後點擊返回鍵返回WeatherFragment後，再點擊Show Forecasts按鈕，ForecastsViewModel中的viewModelScope.launch()的block()不會被調用，目前看起來是因為觸發過ForecastsViewModel的onCleared()。

目前的解決方法，是將viewModelScope修改成GlobalScope，如下圖所示。你有什麼想法嗎？或是比較好的解決方法？謝謝。 2020-01-17_001909
