Clicking on one of the tabs is causing delay of a second or two. Can't confirm that's the calculation delay or the garbage collector delay to free up the memory for a bitmap which is on that tab.
The log is having some dalvik processing to free up memory like -
04-02 11:45:58.109: D/dalvikvm(1930): GC_CONCURRENT freed 1638K, 21% free 15516K/19591K, paused 12ms+4ms, total 222ms
Is there a way to run Progress bar during the time the VM is freeing the memory for the bitmaps ?
This way the application user doesn't have to wait on a tab click as sometimes the delay is long enough that the user may think that nothing is happening.
