What Android version to target?
<p>I'm about to write my first Android app. It's a fairly basic app that doesn't use any special features beyond being able to schedule notifications and read/write image files to the device's local storage. Reaching the broadest audience is my top priority. If I target Android 1.5, is the app guaranteed to run fine all the way up to ICS? Should I target Android 2.1, which seems to be the new baseline for common phones in use?</p>

<p>Since the app is fairly basic, if I target ICS, would it run on versions going all the way back to 2.1? Maybe this is a stupid question.</p>
