Android studio is using the wrong apk file path when I use my own build.gradle file

So I'm trying to use a custom build file that generates an unsigned apk, then runs a task on it, and then zipaligns. I haven't gotten this job yet. However, I have it creating and signing the apk correctly, but when I try to just hit the play button to start it while debugging on the device using my own debug setting, studio / gradle creates my apk and puts it in the directory I am but it cannot push it to device because it uses a file path that doesn't exist. I / O error: C: \ ProgramData \ Microsoft \ Windows \ Start Menu \ Programs \ Android Studio \ apk \ V2.5-10-debug-20140922-2335.apk (the system cannot find the path specified). Is this hardcoded into the studio build because I can't find a setting to change it.It really makes the whole process a real pain. Infact that path doesn't exist anywhere on my machine.

EDIT heres my build.gradle file

import java.text.SimpleDateFormat
import java.util.regex.Pattern

apply plugin: 'com.android.application'


def buildTime() {
    def df = new SimpleDateFormat("yyyyMMdd'-'HHmm")
    df.setTimeZone(TimeZone.getDefault())
    return df.format(new Date())
}

def apkName = "MyApp"
def apkLocation

task (runApkSigTool , dependsOn: android, type: JavaExec) {

    classpath files('apksigtool.jar')
    main 'com.widevine.tools.android.apksigtool.ApkSigTool'
    args[0] = apkLocation
    args[1] = 'private_key.der'
    args[2] = 'my.crt'
    System.out.println(apkLocation);
}
