Apparently there is a bit of competition going on between Google and Amazon. I uploaded my apps to both Google and Amazon. They used to upload easily from Amazon but now they only come through as Amazon Underground. I don't quite understand it but I suspect that Google is making it hard for Amazon to sell Android apps. As for as I am concerned I would let the user use the service that he already knows.
I would like to make another android app Got Ya! A mouse would be tied to a string. Movement of the mouse would take a 30 second video and gmail it to you. It would be a cheep way to temporally monitor something using your existing tablet. Maybe this will happen 2017 as I am burnt out now. https://www.amazon.com/s/ref=bl_sr_mobile-apps?_encoding=UTF8&field-brandtextbin=Znidarsic%20Science%20Books&node=2350149011 I am restoring my Radiola 3. Does anyone know where to get 2 VX-99 or 864 tubes. Any pair of tall skinny 4 pin triodes will do as I will have to make a heater power supply and tube socket anyway. Perhaps I will stick two MOSFETs under the chassis for operation and mount any old tube that will light up on the surface for show. I makes me sad to work on this thing as everyone who developed it, sold it, and used it new is either 110 years old or dead. Frank Z
