I recently needed to use Google GCM in my project. From its website it is said:
Firebase Cloud Messaging (FCM) is the new version of GCM. It inherits the reliable and scalable GCM infrastructure, plus new features! See the FAQ to learn more. If you are integrating messaging in a new app, start with FCM. GCM users are strongly recommended to upgrade to FCM, in order to benefit from new FCM features today and in the future.
In order to setup a new Firebase application, I've followed the instructions provided at the official website and did the following:
- Created a new Firebase app in the web console and got my json from there - after providing the correct package of my app;
- At the top level project's gradle file, I've added
classpath 'com.google.gms:google-services:3.0.0'in the dependency section; - At my module's gradle file, I've added:
compile 'com.google.firebase:firebase-core:9.0.0' compile 'com.google.firebase:firebase-messaging:9.0.0'and in the last line of it, I've added:apply plugin: 'com.google.gms.google-services';
Full Gradle files are provided below:
Top level gradle file:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.1.0'
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.7'
classpath 'com.google.gms:google-services:3.0.0'
}
}
allprojects {
repositories {
jcenter()
maven { url "https://jitpack.io" }
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
Module's gradle file:

}

When I start my app I get this stacktrace:

Any help solving this problem will be very appreciated! Regards
Well, after struggle a lot I found what was causing my problem. Basically I had two libraries modules - that happened to be of my own - each one of them importing different versions of com.android.support:appcompat-v7.* and google play services. Made all of them import the same version and problem is gone.
I met the same error, solved by upgrade firebase-core:
dependencies {
compile 'com.google.firebase:firebase-core:9.0.2'
}
Care to see that all the dependencies should have same version
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2',
{
exclude group: 'com.android.support', module: 'support-annotations'
})
implementation 'com.android.support:appcompat-v7:25.2.0'
implementation 'com.android.support:design:25.2.0'
implementation 'com.android.support:support-v4:25.2.0'
implementation 'com.google.firebase:firebase-auth:10.0.1'
implementation 'com.android.support:cardview-v7:25.2.0'
implementation 'com.google.firebase:firebase-database:10.0.1'
testCompile 'junit:junit:4.12'
}
I faced the Same Issue, but after some r & d and I came to known the problem was in Gradle i.e, compile "com.android.support:support-v4:+" then I just removed the + and replaced actual version ie, compile "com.android.support:support-v4:23.1.0" then it started working
For me a completely unrelated import caused this error compile 'com.aurelhubert:ahbottomnavigation:1.3.3' When I removed it everything was fine
In my case, the problem occurs because i had put "apply plugin: 'com.google.gms.google-services'" inside the dependencies of the modules build.grandle insteand of putting it at the end of the file.
I had the same issue, fixed by upgrading to play-services-auth:10.0.1:
dependencies {
......
//implementation 'com.google.android.gms:play-services-auth:9.0.0'
implementation 'com.google.android.gms:play-services-auth:10.0.1'
....
}
You can check the dependencies with gradle command
./gradlew app:dependencies
As Edgar said ensure that all the dependency libraries has same version. If not then you can exclude that dependency using
compile('your dependency') {
exclude group: 'lib to be removed'
}
And add that dependency yourself.
add compile 'com.google.android.gms:play-services:9.0.0' into your app level build.gradle file
Me, after struggle all night because my dependencies' version are the same. After adding Firebase Analytics, when I edited the code and run to my device my app crashed with Rejecting re-init on previously-failed class com.google.android.gms... I have to clean project and run again, then it worked fine but will be crashed again if I edit the code.
My problem was caused by "useProguard false" from following this guide https://developer.android.com/studio/build/shrink-code.html
debug {
minifyEnabled true
useProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'),
'proguard-rules.pro'
}
but I disabled Instant Run so remove "useProguard false" fixed my problem.
debug {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'),
'proguard-rules.pro'
}
More complete answer for newbies. @Edgar is correct, Thanks!
Error: "Firebase API initialization failure" can be found in logcat of Android Monitor is due to incompatible library version. And it can be any libraries that you compile your app with in Project perspective: go to: Your-app-directory/app/build.gradle
In my case I have to match these 2 module version and that solved this error message:
implementation 'com.google.firebase:firebase-core:16.0.1'
implementation 'com.google.firebase:firebase-appindexing:16.0.1'
I attached here the screen shot so you can see all of it.
In My case i forgot to add this with in App Level build
implementation 'com.google.firebase:firebase-messaging:9.6.0'
So i got the FireBase firebase-api-initialization-failure
