Android code to pure java
<p>I want to know which is the tag used in pure java instead of the following codes in android</p>

<pre><code>Looper
ViewerApp
inputMgr
getWindowToken()
InputMethodManager
</code></pre>

<p>For example in pure java we use JOptionPane instead of toast in android.
What is the use of ViewerApp in android and also looper in android.
Please help....</p>
