Help me please. Can not create apk. The application works in the emulator.
Maybe you need to do something in the gradle?
Build.gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "com.example.shcherbuk96.example2firebase"
minSdkVersion 16
targetSdkVersion 25
versionCode 1
versionName "1.0"
multiDexEnabled true
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.firebaseui:firebase-ui:0.6.2'
compile 'com.firebaseui:firebase-ui-auth:0.6.2'
compile 'com.google.firebase:firebase-auth:10.2.0'
compile 'com.google.firebase:firebase-database:10.2.0'
testCompile 'junit:junit:4.12'
}
apply plugin: 'com.google.gms.google-services'
Errors:
Error:java.lang.RuntimeException: com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/google/android/gms/auth/api/signin/internal/zzf.class

It means that you are adding the same class twice (with different versions).
It happens because you are using FirebaseUI.
Each version of FirebaseUI has dependency on a fixed version of firebase libraries.
Check the table
For convenience, here are some examples:
FirebaseUI Version Firebase/Play Services Version
1.2.0 10.2.0
1.1.1 10.0.0 or 10.0.1
1.0.1 10.0.0 or 10.0.1
1.0.0 9.8.0
0.6.2 9.8.0
0.6.1 9.6.1
0.6.0 9.6.0
Then you have to change your dependencies:
compile 'com.firebaseui:firebase-ui:1.2.0'
compile 'com.firebaseui:firebase-ui-auth:1.2.0'
compile 'com.google.firebase:firebase-auth:10.2.0'
Also if you are upgrading a project to version 1.x.x you may encounter the error Failed to resolve: com.twitter.sdk.android:twitter:2.x.x when syncing your project with Gradle.
Version 1.0.0 has added a new required configuration step.
To resolve this issue you must add the Fabric repository to your repositories:
repositories {
// ...
jcenter()
maven { url 'https://maven.fabric.io/public' }
}
