Right version of the android google play services

I'm building an android app to store a text file in the google drive.According to my perspective, the code is OK. But when I put the app level dependency of the google play-services, it throws an error in the app level version dependency. Due to this reason, I cannot sync the gradle. I think the error is with the version numbers.
here is the play service dependency I put
"compile 'com.google.android.gms:play-services:8.4.0'"
And this is the dependency that shows as an error when I put the above dependency
"compile 'com.android.support:appcompat-v7:23.4.0'"
Here is my app level graddle
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "com.example.xxxxx.calllogtogoogledrive"
minSdkVersion 19
targetSdkVersion 23
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
testCompile 'junit:junit:4.12'
compile 'com.google.android.gms:play-services:8.4.0'
}
Here is the project level gradle
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.2'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

Could you try to change your build.gradle like this;
allprojects {
repositories {
maven { url "http://jcenter.bintray.com" }
}
Remove jcenter() add this.

Problems when create a project in Android Studio

I made a new project in android studio, when this finally was created in the main activity marked some errors, one of those errors is the AppCpmátActivity, i know that this is because I don't have the compile exported, but I have it exported in my Build.Gradle (Module App). but when i want to sync the gradle, this show me the next errors
this is my build.gradle (Module: App)
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
buildToolsVersion "26.0.1"
defaultConfig {
applicationId "demontechsystemsecurity.trackingtool"
minSdkVersion 15
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:26.+'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
testCompile 'junit:junit:4.12'
}
I don't know what's really the problem because I opt by downloading all the sdk tools and
this is the build.gradle (Project: Project Name)
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
if I add in the repositories google() it showme this
but is the same if I click over Upgrade plugin to version 2.3.3 and sync project this doesn't make any action

Add maven { url "https://maven.google.com" }
allprojects {
repositories {
jcenter()
maven {
url "https://maven.google.com"
}
}
}

Kotlin in android studio

I am using from kotlin but when I sync it in my project get me bellow error :
Error:Could not find org.jetbrains.kotlin:kotlin-gradle-plugin:1.1.2-3.

Here is my build.gradle(Module) :
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'

defaultConfig {

And here is my build.gradle(project) :
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
ext.kotlin_version = '1.1.2-3'

}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

ext.kotlin_version = '1.1.2-3'
'1.1.2-3' version is not available in jcenter repo neither it is available in your file system.
As I check the latest version 1.1.2-2 is available in jcenter that is last update on Apr 28, 2017 so use 1.1.2-2 version instead of 1.1.2-3.
ext.kotlin_version = '1.1.2-2'

The Kotlin Gradle plugin version which you set is not still available on repository.
Try setting to any other version like:
ext.kotlin_version = '1.1.1'
