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.

In your project build.gradle file, this:
classpath 'com.google.services.gms:google-services:3.0.0'
should be:
classpath 'com.google.gms:google-services:3.0.0'
To resolve the twitter error, update your project build.gradle:
allprojects {
repositories {
jcenter()
maven { url 'https://maven.fabric.io/public' } // <= ADD THIS
}
}
It's needed by Firebase Auth UI.

AndroidStudio not finding RealmRecyclerViewAdapter - android realm-plugin:2.2.2

AndroidStudio 2.2.3 is failing to resolve my RealmRecyclerViewAdapter reference. I've followed the RecyclerViewAdaper example straight from the Realm site. Could someone help me figure out why it's not finding RealmRecyclerViewAdapter?
Here are my import statements:
import io.realm.OrderedRealmCollection;
import io.realm.RealmRecyclerViewAdapter; //this fails
Here's my project-level gradle file:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.2.3'
classpath 'io.realm:realm-gradle-plugin:2.2.2'
// 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
}
Here's my application-level gradle file:
apply plugin: 'com.android.application'
apply plugin: 'realm-android'
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "com.creditcardcalcx"
minSdkVersion 23
targetSdkVersion 25
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-v7:25.1.0'
testCompile 'junit:junit:4.12'
compile 'com.android.support.constraint:constraint-layout:1.0.0-beta4'
compile 'com.android.support:recyclerview-v7:25.1.0'

Yeah, you're missing the following dependency
dependencies {
compile 'io.realm:android-adapters:1.4.0'
}

Gradle can't resolve any of my dependencies

For some reason gradle can't resolve any of my dependencies. This is an example:
Module:
apply plugin: 'com.android.application'
android {
compileSdkVersion 24
buildToolsVersion "24.0.2"
defaultConfig {
applicationId "app.simplelogin"
minSdkVersion 15
targetSdkVersion 24
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-v7:24.2.1'
compile 'com.squareup.okhttp3:okhttp:3.0.1'
testCompile 'junit:junit:4.12'
}
Project:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.2.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
mavenCentral()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
When I try to sync or build, I get the following error:
Failed to resolve: com.squareup.okhttp3:okhttp:3.0.1
I get this same error message with every dependency I try to add - anyone know why?

You probably have switched on offline mode in the Gradle tool window of Android Studio. Switch off offline mode and it should work if you have internet connection.
