I have made a small app for Android which is responsible for scanning Wi-Fi networks, the app works well, the problem is that I don't know how to add widgets every time there is a new network. What I want is that every time there is a new Wi-Fi network, a new widget appears with the data of that Wi-Fi network, I don't know if I explain myself, in my example I put several transparent buttons on the in which the button text is a wifi network, the bad thing about this is that when there are 4 or less wifi networks the buttons are still there, I want each new wifi network to add a button with the wifi network information,I'm still learning kivy I need help thanks!
