How i'm finding android:debuggable flag in AndroidManifest.xml

build.gradle

boolean getDebuggable() {
    def debuggableFlag = null;
    def manifest = new XmlSlurper().parse(file("AndroidManifest.xml"))
    def groovy.util.slurpersupport.NodeChild app;
    def ns = new groovy.xml.Namespace("http://schemas.android.com/apk/res/android", "android")
    manifest.children().find { it.name() == "application" }.each {
        def groovy.util.slurpersupport.NodeChild application = it;
        def debuggable = application.attributes().get(ns.debuggable.toString())

        //println application.attributes().toMapString()

        if (debuggable == "false") {
            //return false //return not working
            debuggableFlag = false;
        }
        if (debuggable == "true") {
            //return true //return not working
            debuggableFlag = true;
        }
    }

    return debuggableFlag
}

task test1 {
    description "find debuggable flag"
    doFirst {
       println getDebuggable()
    }
}
