title: Android grow heap frag case
body: <p>I'm working on an app to streaming music from internet... My app does many things and it's structured in this way: I have a tab view and every view is allocated in memory so every time I navigate through tabs I find again the previous status ( every tab can also open a webview to find information about songs, news etc in internet ).. all that grows memory occupation but makes the app very user friendly... After having paid attention to avoid memory leaks following the Android guide, I tried to look at the heap occupation and I found that my app allocates max 3.5MB of memory and the heap size allocated is 4.5 - 4.6 MB... I'm working on the emulator .. They are not so much I think, but sometimes my app is restarted founding in LogCat a strange message like</p>
  
  <pre><code>Grow heap ( frag case ) to 3.373 for 19764-byte allocation
  </code></pre>
  
  <p>What is it? an emulator issue? or something else? Am I using too much memory?</p>
  
  <p>Thank you in advance for any help :)</p>
