What's the Android "Extracted Text UI"?
<p>I recently had a bug where my small EditText was ballooning up to fill whatever space wasn't consumed by the soft keyboard.   But only in Landscape mode.</p>

<p>I posted this and got a quick response from a helpful StackOverflow member that I needed to add <em>android:imeOptions="flagNoExtractUi"</em>, so I did and it worked!   </p>

<p>But I still don't understand it.   The documentation says that it's <em>"Used to specify that the IME does not need to show its extracted text UI"</em>     OK, what's that?   The "search developer docs" feature of <a href="http://developer.android.com" rel="nofollow">http://developer.android.com</a> shows the phrase "Extracted text UI" used 34 times in their documentation but I didn't notice a definition.</p>

<p>Could someone please explain what it is, and why it only affects Landscape mode?   Thanks in advance.</p>
