My mobile is Micromax Canvas HD Plus .It has 4 GB inbuilt memory and 16 GB external memory card.I have selected SD Card as default location to install apps but still when I try to install app from Play Store it shows above error.My SD Card is nearly empty.

I searched a lot .Uninstalling Play store updates,Clearing Cache nothing worked.
