title: Android Studio AAPT err: libpng error: Not a PNG file
body: <p>I have search all the possible available solution but still i am facing same issue with unclear error for me.</p>
  
  <p>Now the complete error is-</p>
  
  <p><strong>AAPT err(Facade for 370671127): libpng error: Not a PNG file
  Error:Execution failed for task ':app:mergeDebugResources'.</strong></p>
  
  <blockquote>
    <p>Some file crunching failed, see logs for details </p>
  </blockquote>
  
  <p>Now from this line <strong>libpng error: Not a PNG file</strong> actual i am not getting where is the problem exist either in my any image files or anything else except this.</p>
  
  <p><strong>1-</strong> Before posting this issues i have changed my all the images existing in the diff-2 folders in required <strong>PNG formates</strong> as I see as solution in other post.</p>
  
  <p><strong>Note-</strong> Its working fine on eclipse now I am importing this in Android Studio.</p>
  
  <p>Since during project build only single(above) error is shown so I guess there is not should be any other issue. I have spend more time to resolve this issues so all the suggestions are welcomes for me. </p>
