Android Question

Android Studio Suddenly started to display unable to resolve com.android.support...25.0.0 error messages and all of my java files are erroneous now?



My project was working very fine, but until one day, when I uploaded my project to github. I don't know if this issue is related to that but today when I compiled my android studio project, it started showing me these 4 horrible errors. I have tried most of the google results but no help!

Error:Failed to resolve: com.android.support:cardview-v7:25.0.0
Error:Failed to resolve: com.android.support:customtabs:25.0.0
Error:Failed to resolve: com.android.support:appcompat-v7:25.0.0
Error:Failed to resolve: com.android.support:support-v4:25.0.0


This is the screenshot of android studio screen if it helps!

This is my app level build.gradle file:

apply plugin: 'com.android.application'

repositories {
mavenLocal()
mavenCentral()
flatDir {
dirs 'libs'
}
}

android {
compileSdkVersion 23
buildToolsVersion "23.0.3"
defaultConfig {
applicationId "com.google.firebase.codelab.friendlychat"
minSdkVersion 22
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'
}
}
packagingOptions {
exclude 'META-INF/LICENSE'
exclude 'META-INF/LICENSE-FIREBASE.txt'
exclude 'META-INF/NOTICE'
}
productFlavors {
}
}

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:design:23.1.1'
compile 'com.firebase:firebase-client-android:2.5.0'

compile 'com.github.bumptech.glide:glide:3.6.1'
compile 'de.hdodenhof:circleimageview:1.3.0'
compile 'com.android.support:appcompat-v7:23.1.1'
// Google
compile 'com.google.android.gms:play-services-auth:9.4.0'
// Firebase
compile 'com.google.firebase:firebase-database:9.4.0'
compile 'com.google.firebase:firebase-auth:9.4.0'
compile 'com.google.firebase:firebase-config:9.4.0'
compile 'com.google.android.gms:play-services-appinvite:9.4.0'
compile 'com.google.firebase:firebase-messaging:9.4.0'
compile 'com.google.android.gms:play-services-ads:9.4.0'
compile 'com.google.firebase:firebase-database:9.2.1'
compile 'com.google.firebase:firebase-messaging:9.2.1'
compile 'com.google.firebase:firebase-crash:9.4.0'
// Firebase UI
compile 'com.firebaseui:firebase-ui-database:0.4.0'
// Testing dependencies
androidTestCompile 'junit:junit:4.12'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1'
androidTestCompile 'com.android.support.test:runner:0.4.1'
androidTestCompile 'com.android.support:support-annotations:23.4.0'


compile 'com.facebook.android:facebook-android-sdk:[4,5)'
//facebook
}

apply plugin: 'com.google.gms.google-services'


And this is my project level build.gradle file:

buildscript {
repositories {
jcenter()
mavenLocal()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.2.2'
classpath 'com.google.gms:google-services:3.0.0'


// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}

allprojects {
repositories {
jcenter()
mavenLocal()
}
}

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


Why I am starting to get these errors suddenly.

Thanks in advance!
