I'm using the following dependencies:

compile 'com.android.support:appcompat-v7:25.3.0'
compile 'com.android.support:support-v4:25.3.0'
compile 'com.android.support:recyclerview-v7:25.3.0'
compile 'com.android.support:design:25.3.0'
compile 'com.google.firebase:firebase-core:10.0.1'
compile 'com.google.firebase:firebase-database:10.0.1'
compile 'com.google.firebase:firebase-auth:10.0.1'
compile 'com.google.firebase:firebase-crash:10.0.1'
compile 'com.firebaseui:firebase-ui-database:1.1.1'
compile 'com.firebaseui:firebase-ui-auth:1.1.1'
compile 'com.google.android.gms:play-services:10.0.1'

In the Gradle file an error is shown:

All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 25.3.0, 25.1.0, 24.0.0......

I can't update

com.google.android.gms:play-services:10.0.1

because i get the following error:

Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 10.0.1.

When i remove the Firebase dependencies the error is gone. What causes this error and how can i get rid of it?

The com.firebaseui:firebase-ui-auth:10.0.1 library has transitive dependencies on:

com.android.support:cardview-v7:25.1.0
com.android.support:customtabs:25.1.0

You can force use of a newer version by explicitly including it in your dependencies:

compile "com.android.support:cardview-v7:25.3.0"
compile "com.android.support:customtabs:25.3.0"

The other version listed in the warning message, 24.0.0, must be from the Play Services library. In Android Studio, you can open the Gradle window and double-click on :app > Tasks > android > androidDependencies to get a dependency report to find the conflicting libraries.

I would also strongly recommend replacing:

compile 'com.google.android.gms:play-services:10.0.1'

with the specific APIs you need. They are listed here in Table 1. Including the single play-services library pulls in ALL the APIs, needlessly increasing the size of your APK and frequently requiring Multidex.

See this related question for further discussion of this issue.

did you add the classpath 'com.google.gms:google-services:version· to the dependencies and the apply plugin: 'com.google.gms.google-services' to the build.gradle ? and change the compile 'com.android.support:support-v4:25.3.0' by com.android.support:support-v7:25.3.0'
