Running debug on older Android 4.4.2 using Android Studio - android-studio

Question

I am trying to debug on an older Android device (Samsung Tab3 4.4.2). The strange thing is I am getting an error that I do not see when running on my new devices (Android 6+).
When I hit the debug button, a Gradle build is shot off and I get the following error:
06/21 15:55:35: Launching splashActivity
The APK file C:\Users\me\Documents\src\myapp\build\outputs\apk\MyApp\debug\10-MyApp.apk does not exist on disk.
Error while Installing APK
The file is not there, but is not there when I run against the newer versions, which successfully debug. Is Android Studio doing something different due to the older version? Do I need to make some sort of Gradle adjustment?
My Gradle build appends a version to the front of the APK, could that be the problem? Here is the Gradle file (I have removed the flavors, have a ton of them):
buildscript {
ext.kotlin_version = '1.1.1'
}
android {
compileSdkVersion 26
defaultConfig {
applicationId "com.myapp.app"
minSdkVersion 15
targetSdkVersion 23
versionCode 10
versionName "1.1.10"
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_7
targetCompatibility JavaVersion.VERSION_1_7 }
}
aaptOptions {
cruncherEnabled = false
}
dexOptions {
javaMaxHeapSize "4g"
jumboMode true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
productFlavors.whenObjectAdded { flavor ->
flavor.ext.set('directoryPath', '')
flavor.ext.set('apkName', '')
}
flavorDimensions "default"
productFlavors {
MyApp {
signingConfig signingConfigs.config
directoryPath = 'myapp'
}
Flavor1 {
applicationId 'com.flavor1.flavor'
signingConfig signingConfigs.config
directoryPath = 'flavor1'
}
}
applicationVariants.all { variant ->
variant.outputs.all {
def apkName = variant.productFlavors[0].apkName
def flavor = variant.productFlavors[0].name
if (apkName != '')
flavor = apkName;
//add here your logic to customize the name of the apk
outputFileName = "${variant.versionCode}-${flavor}.apk"
}
variant.assemble.doLast { assemble ->
//copy the apk in another directory, add here your
//logic to customize the destination folder
copy {
from variant.outputs*.outputFile
into "C:/AndroidBuilds/MyApp.Build/${variant.productFlavors[0].directoryPath}"
}
//if you don't want to delete the file after copying it comment the line below
delete variant.outputs*.outputFile
}
}
}
I have removed dependencies and such to make it smaller, and changed names to protect the innocent.

Doh, it was the following line of code in Gradle, that was deleting the variant. Apparently it is needed to run on older versions of Android:
//if you don't want to delete the file after copying it comment the line below
// delete variant.outputs*.outputFile
