Thanks for the link. I'm embarrassed to ask this; but I don't know how to install it. I downloaded the apk and put it on my SD card; but when I click on it I get the message "can't open file". Any suggestions?
Oops, I'm not even sure I have a package installer. If I tap on the apk and get the message 'can't open file', does that mean I don't have a 'package installer'? If so, where do I get one?
Hi Kate, I'd rather not use the play store, unless I have no other option.
To install an APK not from Google Play first enable installing from Unknown Sources. Up until Android 7 Nougat the option to install from Unknown Sources was located in Settings - Security - Unknown Sources.
Yes, I think you're right; I did install Opera on it. So, why won't it install the pdf reader com.gsnathan.pdfviewer_28.apk?
Hi Kate, I set security unknown, but it still won't install.
P.S. This is Android 6
