Firebase database dependency crashes app

Question

I'm trying to write to my DB with the following "Set up Firebase Realtime Database for Android" example but the app crashes on startup.

It's seems because the dependency:

 compile 'com.google.firebase:firebase-database:9.2.1'

The crash log:

FATAL EXCEPTION: main
Process: com.example.giat.myapplication, PID: 3874

MY App build.gradle:

apply plugin: 'com.android.application'

android {
compileSdkVersion 24
buildToolsVersion "24.0.1"

defaultConfig {
    applicationId "com.example.giat.myapplication"
    minSdkVersion 15
    targetSdkVersion 24
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:24.1.1'
compile 'com.google.firebase:firebase-core:9.4.0'
compile 'com.google.firebase:firebase-database:9.2.1'

}


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

How to fix this issue ?

Answer 1

I had same issue when upgrading to Android Studio v3 and upgraded SDKs. Fix consisted in app/Build.gradle to switch to 11.4.2 version:

compile "com.google.android.gms:play-services-base:11.4.2" compile "com.google.firebase:firebase-core:11.4.2"

Into main Build.gradle Move to 3.1.1 version and add maven url

  classpath 'com.google.gms:google-services:3.1.1'
  maven {
      url 'https://maven.google.com'
  }

See https://rnfirebase.io/docs/v3.0.*/installation/android#4.-Install-modules

Answer 2

the problem is with the firebase dependencies ....

this is a version compatibility issue

dependencies {

compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha7'
compile 'com.google.firebase:firebase-database:10.0.1'
compile 'com.google.firebase:firebase-storage:10.0.1'
compile 'com.google.firebase:firebase-auth:10.0.1'
compile 'com.google.firebase:firebase-core:10.0.1'

compile 'com.firebaseui:firebase-ui-database:1.0.1'

testCompile 'junit:junit:4.12'
compile 'com.android.support:cardview-v7:25.3.1'
compile 'com.android.support:recyclerview-v7:25.3.1'

}

mine was a problem with firebase-ui version 1.2.0

then i have changed it with 1.0.1 that matches the other versions of firebase.

Answer 3

I was struggling with this too, had both the play-services and firebase on the same version 10.2.0 and still got the exceptions. It was:

compile "com.google.android.gms:play-services-gcm:10.2.0"
compile "com.google.firebase:firebase-messaging:10.2.0"

I eventually just upgraded to 10.2.1

compile "com.google.android.gms:play-services-gcm:10.2.1"
compile "com.google.firebase:firebase-messaging:10.2.1"

and the exceptions were gone!

Answer 4

If, like me, you have all your firebase things using the same ver. be sure to check all google related ones too.

For me I had:

compile 'com.google.firebase:firebase-core:10.0.1'
compile 'com.google.firebase:firebase-ads:10.0.1'
compile 'com.google.firebase:firebase-config:10.0.1'

and:

compile 'com.google.android.gms:play-services-ads:10.2.1'

The issue for me wasn't that the firebase didn't match across themselves but that they didn't match the google ver. used for ads.

Changing all my firebase ones to use 10.2.1 solved the issue for me.

So make sure all the firebase ones match the other google ones.

Answer 5

This problem is occur because dependency version mismatch means if use all the library firebase related with unique version like following way.

Wrong way :

compile 'com.google.firebase:firebase-ads:9.6.0'
compile 'com.google.firebase:firebase-database:9.4.0'
compile 'com.google.firebase:firebase-core:9.4.0'

Right way :

compile 'com.google.firebase:firebase-ads:9.6.0'
compile 'com.google.firebase:firebase-database:9.6.0'
compile 'com.google.firebase:firebase-core:9.6.0'

Answer 6

This problem is caused by use of inconsistent Firebase library versions. Update your build dependencies to consistently use version 9.4.0.

compile 'com.google.firebase:firebase-core:9.4.0'
compile 'com.google.firebase:firebase-database:9.4.0'
