My son's got a Kurio 7 tablet. I've installed the Amazon App Store on it and noticed not all apps are compatible. Bad Piggies for example won't install. The Amazon App Store says its not compatible with his device. Why is that? Bad Piggies is supposed to support Android 2.2 and the Kurio 7 has Android 4. Other than that it doesn't say anything about the requirements. What other things can make an Android device incompatible with some apps?

There are a few different things on Android that specify whether or not an app is compatible with a device:

  1. The author can specify minimum and maximum supported versions. Meaning that even though 2.2 is supported, 4.0 may not be. (Probably not this in your case). Reference

  2. Apps may require certain features to be available, another thing that the author puts in the manifest. This specifies things like needing a camera, needing an accelerometer, needing internet access, etc. If your device doesn't have one of the features, it may show as not compatible. Reference1 Reference2

    • Here is a list of possible features that may be required by the app's developer.

As an example for #2:

When you declare "android:required="true" for a feature, you are specifying that the application cannot function, or is not designed to function, when the specified feature is not present on the device.

    So is there any way to check which requirements my tablet is lacking for particular apps? – jiggy1965 Dec 14 '13 at 15:34
  • Not that is easy, as far as I am aware. Many times you can tear apart an APK to see the manifest, but that's a bit more involved. – nerdwaller Dec 14 '13 at 15:40
