title: android development open file txt and return content
body: <p>Search all over the internet and could not find a working code.
  How can i get content of a txt document and return it.</p>
  
  <p>Suppose i have a txt file in ( src/my.proovi.namespace/data.txt )
  And i created a method called refresh_all_data(); where i want the data to be collected and returned.
  In the main activity method i just need to get the content as ( String content = refresh_all_data(); ) And thats it. </p>
  
  <p>Should be easy but just cant find a working answer.
  Thank you very much.</p>
