Error in google colab

I am trying co convert python file to apk using google colab and all the commands are fulfilled quickly except the last command. It takes a long time and the page shows page unresponsive error and then shows “save filed”. I tried more than 10 times but same issue. Is this related to internet connection or something else. Can someone suggest something on how to get around this?
