问题
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

// Firebase

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!

Open your android SDK manager (from C:\Users\youruseraccount\AppData\Local\Android\sdk) and update following to latest versions in,
Tools section section
Android SDK Tool
Android SDK Platform-Tools
Android SDK Build tool
Android 7.1.1 (API 25) section
- SDK Platform
Extras Section
- Android Support Repository
- Android Support Library
Then update your gradle file accordingly.

Facebook updated their SDK to use the latest support libraries. You could replace
compile 'com.facebook.android:facebook-android-sdk:[4,5)'
with
compile 'com.facebook.android:facebook-android-sdk:4.16.1'
if you do not want to update your android sdk just yet.

I had the same problem earlier today. Out of nowhere, I started having those weird error messages. Updating:
- Android SDK Tool
- Android SDK Platform-Tools
- Android SDK Build tool
- Android Support Repository
did the trick for me. Just go to Tools > Android > SDK Manager in your Android Studio then find and update them. Good luck!
回答4:
If you try to remove facebook-sdk compile from dependencies will not show that error. So i think is facebook sdk error.
I was using 'com.facebook.android:facebook-android-sdk:[4,5)' but gives error, i tried this com.facebook.android:facebook-android-sdk:4.+ but is the same. But when i remove it app build successfully. Am i the only i came in this conclude and having the same problem ?
回答5:
if you are using cardview with 25.0.0 version then i think your issue is with your target sdk version. Make it 25 and things should work otherwise downgrade your cardview and other libraries from 25.0.0 to 23.x.x
回答6:
Just updating the Android support repository version to 25 did my work. Thanks to all of you for the guidance!
回答7:
If you added the latest Facebook SDK or using + for Facebook dependency, revert to a previous version
compile 'com.facebook.android:facebook-android-sdk:4.16.1'
