android apps not getting dowloaded from playstore today i tried to download an application from play store. but instead it showed the error message not enough store space in device memory. i tried to search the solution for it on net. 
so i did few things like.
1. go to settings> all application> then Google play services clear cache ,clear data , force stop it.
2.  and then do the same thing for Google play store.

but they also didn't work. what should i do.
Maybe simply there isnt enough storage as stated in the error.

Apps are installed in data patition not your internal sd card. Dont be misleaded by that. There are /cache /data /system partitions .Preinstalled system applications are in read only /system partition. When you install app from play store it will be installed in /data partition and its limited. My 16 GB phone has only 2GB data partition

Try to clear some other applications data
