[Q] Out of space...

Hi all... when i trying to install an app an error popup saying that memory out of space and told me to clean up more room for installation. i tried to download the apk from internet and use play store to install, also pop the same error....

but both of my phone and sd card memory should be sufficient for that app. the strange point is that other apps are able to be install at the meantime...

does anyone know whats wrong with it? appreciate any kind of help n advice, thanks a lot
