Collect screen size and density

[yanokwa]

When making design decisions, it would be good to know the most popular screen sizes and densities. For example, we know people use phones, but are they small phones or big phones? How much stuff can we really stuff on the screen? What are reasonable font sizes to default to.

Google has the screen size data for the entire Play Store at https://developer.android.com/about/dashboards/index.html#Screens, but I doubt it is representative of our user base.

I have looked through the Google Analytics, Play Store, and Firebase and I can't find this data. The best we can do currently is know the mobile vs tablet ratio. We also know device model through Google Analytics, but it's a long tail and 14% of those devices don't have a model set :(.

I propose we capture the screen size (small, normal, large, xlarge) and the density (ldpi, mdpi, tvdpi, hdpi, xhdpi, and xxhddi) on app load.

I think this information is useful, it's not, please push back. I'm also aiming for collecting the most narrow data we think is useful. I'm very open to finding some way to more rigorously get the device model so we can maybe recommend popular devices, know how much RAM devices have, etc.
