Thanks! It's a good option using an emulator. If you don't mind, I would tell you my worries:
That's my point:
I'm a teacher in Brazil and I'm supposed to teach my students some projects. I was doing them; I test them with my android device (I tried to use my Iphone 7 plus, but in this specific project it was getting me a long time, so I decided to give it a try on the Samsung S6. It worked just perfectly!). And then I show to my students.
For a while, we are having online classes, so the students can use their own computer and devices to try the apps. But in the school, the computers just don't open the emulator nor conect with cellphones. I could make one single computer open the emulator and it worked fine last month when we were at school, but the students couldn't make it work in the others computers in the school.
In my personal computer (where I am now) I could always use this aproach with the emulator. So I could share my screen for the students besides openning and running it on my cellphone (so I took some photos and made some videos of it working so the students could see).
I need something that could make the emulator work properly, because if I suggest MemuPlay I don't think the school would let me download and use it. The students just would install lots of games.
If you have some suggestion, or if you could explain me this "dance":
I would give it a go.
Thank you for the help so far.
