We've just posted a very rough beta which includes a prototype of this feature. This is not a promise that we'll release the feature, but we are hopeful.
We are prototyping a third-party library to render the PDF contents so you'll see a watermark on embedded PDF maps, but don't worry about that. What matters is that they're accurate and they render ok. The button to display a georeferenced PDF is the big gray blob to the right of the Plates window listing for the document. We'll improve the graphics for it if/when we release the feature, obviously.
Feedback wanted!

We require no more permissions than are absolutely necessary:

Internet
WriteExternalStorage
AccessFineLocation
AccessCoarseLocation
AccessNetworkState

To my knowledge, it is these and only these which the Play Store uses to determine whether an app is compatible with your device. I am happy to be corrected with a specific setting that I'm not aware of, but you really will need to be specific. Perhaps you could share your response from Google with us?

I already did give Google's response to Hannah, who said I needed to contact Google as it was my problem.

"According to our records, the app you're referring to is not compatible with your device because your device is missing a GPS feature and so it won't be advertised to you in Google Play.

App compatibility is determined by individual app developers, not by Google Play, so I'm afraid I can't help further - I can't change the requirements this developer has set for their app.

That being said, I'd recommend contacting the app developer directly to see if they plan to expand compatibility in the future or if they have other options for your device. "

As the Beta direct download works fine there would appear to be no reason for the "GPS feature" Google say is the issue.

Hope this helps.

If the settings can't be changed how about having a permanent download page in the Customer area of SkyDemon?
