I just downloaded esp8266 master android project from github and tried to make it work.unfortunately once I click connect button it stays in the progress bar status (pic attached) and doesnt move to the next page where we send commands for on/off. Any clue will be helpful. Iam using android 8.1. I did see in the wifi settings that the phone is connected to the esp module. So the connection did take place but somehow the app doesnt get reponse back saying that is connected. I am using Android 8.1
Below is the code from github for ur reference.
