Install PWA doesn't work with all Android launchers

[jgaehring]

@symbioquine brought up in the monthly call that when using non-stock Android app launchers, the install process for the PWA gets broken. It might be worth exploring this in conjunction with #362.

I haven't forgotten about this, but my test device backlight has been failing so I'm waiting for a replacement before posting more info here.

@symbioquine, I plan to take a look at this at some point in the next day or so. Do you recall which app launcher(s) you were using that had trouble?

I just re-tested with the following results;

Working:

• Pixel Launcher
• Nova Launcher
• KISS Launcher
• Lawnchair Launcher
• Rootless Pixel Launcher
• Niagara Launcher

Not Working:

• Launcher<3 - https://github.com/jasonkung0211/launcher3/issues/6
• Slim Launcher - https://github.com/sduduzog/slim-launcher/issues/95

The behavior when "not working" is interesting... in Firefox Nightly anyway the menu item is just missing for "Install" A.K.A. "Add to Home Screen";

Whereas it normally looks like;

Great info, @symbioquine, thanks for following up!

From the sounds of those issues you linked, it doesn't seem like something we'll be able to fix on our end. Seems like a general limitation of those launchers. We'll just have to be aware that such limitations exist when weighing the costs/benefits of PWA's.

I'm going to close this unless any new information comes up. Thanks again for reporting!

@jgaehring The point I was trying to make during the monthly call is that some users might not be able to find how to "install" the PWA. It might be a good idea for any documentation on installing the Field Kit PWA to call out that the "Install" A.K.A. "Add to Home Screen" functionality is dependent the mobile OS/launcher supporting that feature.
