title: Android: Which image format shall I use and why?
body: <p>Im a beginner programmer, and my question is:
  Which image format shall i use for my android app?</p>
  
  <p>Descripton:
  I only use illustrations, so the images are mostly background images, and some buttons, and i would like to know which is the best way to do this.</p>
  
  <p>My current progress for images are the next:
  I use .png file format. I dont know what resolution should I use, now I work with 300x400 px images aproximetly.</p>
  
  <p>Here is my code for using the images:</p>
  
  <p><code>Bitmap bMap = BitmapFactory.decodeResource(getResources(), MyArray[index].getArtiD());</code></p>
  
  <p><code>MyImageView.setImageBitmap(bMap);</code></p>
  
  <p>So this is the way I use images in Android, pls guys if anyone know issues, tips or a "must know information" to tell pls do it. I dont really understand why should I use this bitmap factory or why should i use png format. I want to do it in the best way I can, and I dont see many things in android documentation.</p>
  
  <p>Thanks,
  Adam</p>
