You are not using App Inventor. Ask in the community of the builder you use. I unlist this.
I know but I need help just that please
Builders are much to different. Like I said ask in the builders community or make a sample with App Inventor and post it here.
I bought this extension and I would like to know how I can take a photo, preview the image and with a button upload it to my host via ftp.
I would be very grateful if you could help me, I'm going on this for two months.
