title: Where does application data file actually stored on android device?
body: <p>I have developed an Android app using Appcelerator Titanium. This app will create a file in applicationDataDirectory and install a database as well.</p>
  
  <p>If run on emulator, I can locate those files using "adb" command. But how about on Android device? Can I use the "My Files" app to view those file I created? (since I can see files created by other application there.)</p>
  
  <p>Moreover, I expect once I removed the app on device, it will automatically remove the related files and database. Is that true?</p>
  
  <p>Because I found that even I removed the app from the device, the database seems left behind. I can tell because after deleting app and re-run on device(from Titanium), it show previous data.</p>
  
  <p>I am using Ti SDK 2.0.1GA2, Android Runtime V8. And using Samsung Galaxy Tab for testing.
  Thanks in advance.</p>
