title: Many image files in res/drawable, How to access in Android?
body: <p>I have to make a dedicated image viewer app for Android 2.x.</p>
  
  <p>There are too many jpeg image files: about 2000~ jpegs, over 100MB.</p>
  
  <p>I want access the image files with their file names,
  but I couldn't find such an example.</p>
  
  <p>By the way, is it okay to put many image files in /res/drawable folder?</p>
  
  <p>I heard that the android application cannot be installed on sdcard and</p>
  
  <p>the program repository is very small so 100MB app cannot be installed generally.</p>
  
  <p>I found some examples which download the large data files on sdcard online,</p>
  
  <p>but I cannot run a web server to host the data files,</p>
  
  <p>and I must upload the fully packaged program on Android Market. (Should I build one apk file?)</p>
  
  <p><strong>What are the best practices for managing too many resource images (or something) in Android?</strong></p>
