• The activity that you are starting is taking too long to do its onCreate part. Try to just "setContentView" in that activity and check if this delay is gone.

• Pankaj - yes, I learned that the bad UI experience was due to the "preview" window... apparently someone at Google decided that a white preview window was really awesome to use by default.

See the section "the perfect preview window" cyrilmottier.com/2013/01/23/android-app-launching-made-gorgeous
