I'm getting a "package not valid" error when trying to install my own custom apk (from BoringName's steps)
So I just recently started to get the 'root folder' issue in my wifi sync app.
Don't quite understand as I haven't had a security update for a few weeks, but oh well. So due to another issue I've had (where wifi sync app stopped seeing 'server' on my desktop), I would have a workaround where I'd clear app data/cache, and it would start working again. Never found root cause, but workaround was fine.
This last time I did it, when I walked through initial setup (which I had to do with wiping data), it would now no longer allow me to use the folder I had been using for months. Again, no recent security update on my phone that I installed, so I have no idea what changed.
So I attempted BoringName's apk process, and am pretty certain I followed it to the letter. I've triple-checked myself, and I think I did it all correctly. But when I take the apk I outputted and send it to my phone, it says the package is not valid -- "App not installed as package appears to be invalid". This is different from the installing from unknown locations -- other apk's in this directory install fine.
Any thoughts on what's making the package invalid? I've tried SDK versions 32,33,34 to see if any would work ... none do.
