Android app install verification

Question

I have an app which list some campaigns(list of apps) that user can install and earn the points. Now here my main concern is security. some of the user installing the apps either from emulator or vpn or something else so that my client is not getting app installs in google play store.

i have seen some apps like cash pirate,app money etc which does not give points if campaign is installed through emulator.

how can i verify that campaign is installed through phone or emulator or vpn.

NOTE : I have already checked Build Model,manufacturer etc for emulator!!

Any advance help would be appreciated !!!

Code

public static boolean checkEmulator() {
    try {
        boolean goldfish = getSystemProperty("ro.hardware").contains("goldfish");
        boolean emu = getSystemProperty("ro.kernel.qemu").length() > 0;
        boolean sdk = getSystemProperty("ro.product.model").equals("sdk");

        if (emu || goldfish || sdk) {
            return true;
        }
    } catch (Exception e) {}

    return false;
}
