Android Studio gradle apk and run out of sync - android-studio

Question

I am using Android Studio and I have the following build.gradle file.
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
dexOptions {
javaMaxHeapSize "4g"
preDexLibraries = false
}
defaultConfig {
applicationId "com.domain.myapp"
minSdkVersion 17
targetSdkVersion 25
versionName "1.0"
versionCode 2
versionNameSuffix = ".alpha1"
def date = new Date().format('yyyyMMddHHmmss')
if (versionNameSuffix.equals("")) {
setProperty("archivesBaseName", "myapp.$versionName.$versionCode")
} else {
setProperty("archivesBaseName", "myapp.$versionName.$versionCode$versionNameSuffix." + date)
}
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
buildConfigField 'boolean', 'IS_DEBUG', 'false'
buildConfigField 'String', 'BUILD_DATE', '\"' + date + '\"'
buildConfigField 'String', 'VERSION_STRING', '\"' + "$versionName.$versionCode$versionNameSuffix" + '\"'
resValue "string", "BUILD_DATE", date
resValue "string", "VERSION", "$versionName.$versionCode$versionNameSuffix"
}
buildTypes {
release {
buildConfigField 'boolean', 'IS_DEBUG', 'false'
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
applicationVariants.all { variant ->
variant.outputs.each { output ->
def newName = output.outputFile.name
newName = newName.replace("-release", "")
output.outputFile = new File(output.outputFile.parent, newName)
}
}
}
debug {
buildConfigField 'boolean', 'IS_DEBUG', 'true'
applicationVariants.all { variant ->
variant.outputs.each { output ->
def newName = output.outputFile.name
output.outputFile = new File(output.outputFile.parent, newName)
}
}
}
}
productFlavors {
}
}
Basically when I Build->Rebuild Project or Build->Build APK, I generate an apk file like myapp.1.0.2.alpha1.20170224125933.apk
The last bit on the end is a time-stamp. (20170224125933 => 2017/2/24 12:59:33)
Everything works perfectly when running manually via the apk.
The issue I am having is that when I try to Run->Run myapp through Android Studio, it seems to always look for an earilier time-stamp.
For example, let's say I Rebuild Project and get the file: myapp.1.0.2.alpha1.20170224125933.apk. I make some code changes and want to Run it through Anroid Studio. When I go to Run, it rebuilds the project again (generating myapp.1.0.2.alpha1.20170224130417.apk) and deletes the previous file (myapp.1.0.2.alpha1.20170224125933.apk) as expected, but, tries to install the previous file. I then get an "error while installing apk. File myapp.1.0.2.alpha1.20170224125933.apk not found."
The only solution I've found is to drop the seconds marker (change the Date format to 'yyyyMMddHHmm'), click Tools->Android->Sync Project with Gradle Files, then immediately hit Run. This usually works unless the clock changes minutes during the few seconds this process takes.
I'm thinking I need a Gradle->Task Activitaion or something so that when I click Run, it generates a new apk, and knows to use the recently generated one.
Any ideas?
