Titanium App low number of supported devices on Play Store

Question

I have an app published in the Play Store build with Titanium, but is showing a really low number of compatible devices and I can't figure out the reason.

The app is built for a min version of SDK 14 and I don't have any strange requirements on permissions. Here is the AndroidManifest.xml generated by Titanium:

    <?xml version="1.0" encoding="UTF-8"?>

I have tested the app in multiple devices in which Play Store says is incompatible, but if you download the app, it works with all the features.

Answer 1

In answer to my own question. Per Android's documentation on how it filters permissions: http://developer.android.com/google/play/filters.html

When you use a <uses-permission> it automatically sets the correct <uses-feature>. So you need to make the correct <uses-feature> NOT required. This solved my issue.

Answer 2

The default for <uses-permission> is to be required. So see if you can override some with required="false" that you don't absolutely need. Then in your code make sure you test for the feature using methodes like hasCompas.
