问题
In my app, I am trying to use gcm services, but I cannot even get gradle to compile. I keep getting the message that I am missing 'firebase core' though I have no idea how to install this.
This is my top-level gradle file:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.1.2'
classpath "io.realm:realm-gradle-plugin:1.1.0"
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
classpath 'com.google.gms:google-services:3.0.0'
}
}
allprojects {
repositories {
jcenter()
maven {
url "https://jitpack.io"
}
maven {
url "https://mint.splunk.com/gradle/"
}
}
}
And here is my module-level gradle file:
apply plugin: 'com.android.application'
apply plugin: 'realm-android'
apply plugin: 'com.google.gms.google-services'
android {
compileSdkVersion 24
buildToolsVersion "24.0.0"

}

回答1:
In your module Gradle file (usually the
app/build.gradle), add the apply plugin(apply plugin: 'com.google.gms.google-services') line at the bottom of the file to enable the Gradle plugin.You should also add the dependencies for the Firebase
com.google.firebase:firebase-coreandcom.google.firebase:firebase-messagingSDK's:apply plugin: 'com.android.application' android { // ... } dependencies { // ... compile 'com.google.firebase:firebase-core:10.2.1' compile 'com.google.firebase:firebase-messaging:10.2.1' } // ADD THIS AT THE BOTTOM apply plugin: 'com.google.gms.google-services'
Make sure you have the latest version of 'Google Play services' and 'Google Repository' installed while using Firebase.
Please follow below steps to install:
- Open Android studio
- Go to the Menu bar > Tools > Android > SDK Manager
- Click on Tab > SDK Tools
- Check and install 'Google Play Services' and 'Google Repository'
- Click on Apply and wait for the download
Finally, Sync and build your project again.

You want to add push notifications in your app ?
use firebase instead of GCM. it is enhanced version of GCM.
You need following dependencies for firebase push notifications.
compile 'com.google.firebase:firebase-messaging:9.0.1'
compile 'com.google.android.gms:play-services-gcm:9.0.1'

回答3:
If you want to add the firebase core, you can add
compile 'com.google.firebase:firebase-core:9.0.0'
under dependencies tag in your module-level gradle file.
If you still can't resolve it, maybe you need to update the SDK to get the Google Play Services rev 30 and Google Repository rev 26 first. See here for the detail.

I had the same problem with com.google.firebase:firebase-core:11.8.0 and it worked after moving the google() repository above jcenter().
In between I used Build -> Clean Project.
./build.gradle
buildscript {
repositories {
google() // <- now on top!
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
classpath 'com.google.gms:google-services:3.1.1'
}
}
allprojects {
repositories {
google() // <- now on top!
jcenter()
}
}
回答5:
In your android/build.gradle in your repositories section, try moving google() ABOVE jcenter().
