Android licence for app
<p>Please clear up something for me. For my own interest I want to write an Android app to use on my phone, by me alone. Maybe written in Mono, or perhaps something else.</p>

<p>It has been suggested to me that I will need to pay a licence fee for this. The Android licensing documentation hasn't cleared this up in my mind.</p>

<p>Do I need to implement any form of licensing or pay any licence for this? I stress, the app will be for use by me alone (and maybe my wife), on my phone alone (or hers). It won't go near Google Play Store or anything like that.</p>
