When I download NanaVNA-Webapp-nightly-e20d9ae.apk from the Github.com/cho45 on my 4 month old Amazon Fire 10. using web browser "Silk" I click on the .apk and get a popup, "Do you Want to Download" I click, "OK" it gives me another popup "Done do you want to open? I click on OPEN and I get "PARSE ERROR - There was a problem parsing the package."
I downloaded the package x2 times. I also tried AKP INSTALLER app I had downloaded and used a number of times.. Same issue. Same error.
Second ITEM.. I have performed the "GOOGLE PLAY install to my Fire" at least 2 months ago, used it a number of times. No problem.. A number of posts talk about downloading "NanoVNA" from GOOGLE PLAY and it will run on the FIRE... When I go to GOOGLE PLAY I do not find any app named "NanoVNA" but find one named BLUE VNA.. and others like Metro VNA by the same author... What is very interesting is I just logged into google play using this Windoze 7 machine and I can find NanoVNA by cho45 just fine. Apparently the issue is on the FIRE. Blue VNA is written by DAn Toma- I can search on either and get it, but NanoVNA or cho45 brings me nothing.. Finally - On my Motorola moto e* plus... NanoVNA by cho45 is 1st on the list...humm.... moto e* is android 8.0.0 the Fire is Fire OS 5.6.4.0... all I can find regarding it's OS.. it was an "on sale" and a lot faster than my 4 yo Samsung.
Merry Christmas..
Consider this post NO COMPLAINT but rather REPORT OF FINDINGS...
