Android studio won't let me use switch on a string?

Question

I'm creating a android app in android studio and trying to create a switch case on a string. As far as i know this is possible, as long as you got a JDK equals to 7 or higher. I'm using the following /Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/Home and still gets an error when trying to switch on a string.

Anyone knows why it still fails, any help is appreciated.

EDIT: I get this eroor Error:(15, 16) error: strings in switch are not supported in -source 1.6 (use -source 7 or higher to enable strings in switch) so clearly somewhere in my project it uses JDK 1.6 but i can't figure out where.

Answer 1

you will have to add this to your build.gradle ( into the android section )

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_7
    targetCompatibility JavaVersion.VERSION_1_7
}

Answer 2

Go to Project "Properties" then Java Compiler , check the "enable project specific settings"

you will get the compiler compliance settings change it to 1.7 and you will be able to use strings in switch
