cannot solve memory exception need work..
nothing fixed .. used weakReference in asyncTask so that garbage
collection is not interrupted..for efficient memory use.
Loading progress bar is displayed while loading images in playlist
thumbnail and pics..
some more changes like use of application context instead of activity
context as application context is global...
problem not solved ....
memory problem solved by using only one fragment in playlist activity..
new bug appeared.. app crashes when orientation changed.
seems memory problem is somewhat solved.
