title: Validating and reading a Word file in Android
body: <p>I want to be able to access a word file in the sdcard of the user's phone, and the file will be chosen by the user. I want to be able to process the file, i.e. read its contents and modify it as the user wishes, and save it when the user clicks “save.”</p>
  
  <p>Is it possible in Android? How can I make the program understand that the file is a Word file?</p>
  
  <p>Note that I don't want to view the Word file. The user will select the Word file and my app should be able to make some changes to it and save it.</p>
