I have an honest question since I think there are plenty of knowledgable people on this forum in terms of Android. I am not, I've had my Nexus 7 for a mere 2 weeks(ish). It is my first experience ever in Android as I am previously an iOS person in the past. I have friends that keep asking me how they can tell what apps will work on the Android device they are looking to get. They are all iOS users mainly and are looking to possibly switch or get an Android device to have both worlds. They are used to going into the App Store and not worrying about this. Which I know the feeling.... I tell them I have no clue. Since I already have a Nexus 7 the Google Play store tells me if something won't work with it. I just took that leap of faith without knowing. Now I'm just downright curious. If someone doesn't own an Android device currently and are researching Android apps in the Google Play store before purchase, how do they tell if the app will work on that particular device? Any current Android user will tell you that all apps won't work on all devices.
