title: Android - What does MEDIA ERROR UNKNOWN -1 ussually means
body: <p>I'm developing an Audio Player (using the MediaPlayer) which works fine on mdpi, hdpi, tablets, but throws a error: MEDIA ERROR UNKNOWN -1 on Samsung Galaxy mini (ldpi).</p>
  
  <p>What I noticed is that this error occurs for majority of songs, though there are 1, 2 songs that still plays on Galaxy Mini.</p>
  
  <p>Why does this error usually occurs?</p>
