I don’t see anything there that would cause problems. Are you selecting “Google Play” as the store when you build?
What version of Corona are you using?
Rob
Hi Rob,
Thanks again for replying. Yes I’m selecting Google play.
Corona version: Version 2017.3135 (2017.9.7)
Anything I can try? Different version?
In the device catalog in the Google Play Console I’m seeing this message on unsupported devices:
This device model is not supported in your app’s APK manifest and hence users of this device model cannot install your app.
How can I access the manifest and ensure that devices like this ARE supported? or at least drill down further to find out what this actually means…
One of the things you can control is the screens your app can run on. See:
https://docs.coronalabs.com/guide/distribution/advancedSettings/index.html#screen-support
Also there is a uses features that can limit hardware based on things like camera availability and such:
https://docs.coronalabs.com/guide/distribution/buildSettings/index.html#androidsettings
We handle all of that behind the scenes unless you choose to override it, which you are not according to your build.settings. Also I don’t know if you have all the right app icons for Android in place or if that could limit you.
Rob
I support these icons (same as default set created when you make a project through corona simulator main screen)

I’ll add the screen support setting to the build.settings and redeploy, see if it helps.
What happens if you use the latest daily build?
Rob
No different. 
This is really bizzare. I just made a test app, and it is pretty much compatible with everything.
Google also tested it on variety of devices and I was able to install on my 2 devices.
I used your build.settings. Are you sure you don’t use any plugins?
I also successfully uploaded an APK and it’s available on over 12,000 devices.
Same here - available on over 12000 devices, including the devices i own however, in the play store it says “incompatible” with my devices. Have raised this as a ticket with Google Play also.
Equally tested in the console, screenshot attached:
For example, I have a oneplus5 - it’s “supported” in the device list - however as you can see from the first screen shot - apparently it’s not!
I remade the app to fit with 1080x1920, ensured large screens are supported as Rob suggested.
Please, see if my open beta app is available on your devices: https://play.google.com/apps/testing/com.coronalabs.vlad.Licensing2
I was able to install it to all my devices from the store.
Another question: you do not use any plugins? Your build.settings is same as you making a build, right?
By the way, that list with checkmarks means that google tested your build on that devices. I would suggest you double check you google play publishing settings. It is possible that problem is not in APK but in store page setup.
In Google Play Publishing portal, try selecting your app, then in right nav. bar select Release management -> Device catalog. Make sure you don’t have devices in “Excluded devices” list. Anyway. Describe what do you see there. I have following:
Got a message from Google saying the account I’m logged in with can’t download my app and they use that message instead of something useful like “You can’t download this app because it’s your” - which is stupid anyway because sure I want a copy of my app and don’t always have my computer around to push an install to!
Thanks for all your help and suggestions, I suspect it’s down to ownership, rather than technical issue on compatibility.
Google Play doesn’t like you doing anything with your developer account on their production Google Play environment. Makes testing IAP a challenge. You can’t buy your own app, etc.
