I'm trying to make my first app (hello world) and run it on my phone, but when I click run, gradle returns this error(i researched here on stackoverflow and tried to turn off instant run but it doesn't seem to work in my case):

later edit: i figured it has something to do with the java version, but i don't know how to update my android studio?

later edit2: i figured it out, i had an older jdk version installed on my computer and the latest android studio, thanks for the help. I just had to install the newest jdk version(8)
