I have Android 4.1.2 on Samsung galaxy S2

I install an app and get this error:

unknown error during appliaction install -24

googling this line should clearing Google play cache might help

but it didn't work for me. Any other solution?

    Why do you need another solution? Doesn't clearing the cache solve the issue? That's the least dangerous thing to do. Of course, a factory-reset might help as well, but that's like using a sledgehammer to crack a nut.

I've just checked that again: "Error -24" in most cases is caused by a failed install/update. To solve it, uninstall the app from your device. After that, you should be able to install it again.
