Frameworks for building dictionaries and language learning apps for Android
<p>I am new to Android and want one of my first apps to be</p>

<ul>
<li>a self-study guide for a certain language and/or</li>
<li>a dictionary for that language.</li>
</ul>

<p>Are there any open-source or low-cost frameworks, which I can re-use for accomplishing those tasks (creating a mobile self-study guide and a dictionary) ?</p>

<p>I assume that I'm not the first person to develop this kind of apps and I'd like to save reduce effort by re-using already existing code, if possible.</p>
