Memory resident android Application
<p>I'm writing an English to Persian dictionary for Android. It works fine as a standalone application, but I need it be resident in memory and  user be able to call ( run ) it on other applications.
For example, user is reading an English text from a web page and needs a word to be translated. He highlights the word, and dictionary application automatically shows the translation.</p>
