In my project it failed to add “firebase” to android studio



I was adding firebase to my project as documented in the official website.



In the 4th step it says to add compile 'com.google.firebase:firebase-core:16.0.0'.


compile 'com.google.firebase:firebase-core:16.0.0'



But trying to synch gradle I would get errors:

and by trying to download them (install repository abd synch project) I would get this error:


install repository abd synch project

here is my gradle dependencies:


dependencies
implementation 'com.google.firebase:firebase-core:16.0.1'
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.google.android.gms:play-services-gcm:15.0.1'
compile 'com.google.android.gms:play-services-location:15.0.1'
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:multidex:1.0.2'
compile 'com.android.support:appcompat-v7:26.1.0'
compile 'com.google.firebase:firebase-auth:11.6.2'
compile 'com.google.android.gms:play-services-auth:15.0.1'
compile 'com.google.code.gson:gson:2.7'
compile('io.socket:socket.io-client:1.0.0')
// excluding org.json which is provided by Android
exclude group: 'org.json', module: 'json'

compile 'com.onesignal:OneSignal:3.6.5'
compile 'com.android.volley:volley:1.0.0'
testCompile 'junit:junit:4.12'



this answer did not work either:
this



update



My project-level gradle:


buildscript
repositories
jcenter()
google()

dependencies
classpath 'com.android.tools.build:gradle:3.0.1'
classpath 'com.google.gms:google-services:4.0.1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files



allprojects
repositories
jcenter()
maven url 'https://maven.google.com'
mavenCentral()
google()






again read plz firebase.google.com/docs/android/setup?authuser=0

Not an answer but use implementation instead of compile.

implementation


compile





Have you added apply plugin: 'com.google.gms.google-services' at the end of your build.gradle file? I cannot see it in your code.

Upgrade the following:


implementation 'com.google.firebase:firebase-auth:11.6.2'



into this:


implementation 'com.google.firebase:firebase-auth:16.0.2'



Add google service plugin version 4.0.1 and google() repo in top level gradle file:


4.0.1


google()


buildscript
// ...
dependencies
// ...
classpath 'com.google.gms:google-services:4.0.1' // google-services plugin



allprojects
// ...
repositories
// ...
google() // Google's Maven repository






I had them all, see my post update. I changed 11.6.2 to 16.0.2 but the same errors again.

Use same versions of firebase services to avoid conflicts.
Refer https://firebase.google.com/docs/android/setup
To solve your problem.





I use the exact codes

Before you proceed, clean and rebuild your project.



Then at app/build.gradle,



add apply plugin: 'com.google.gms.google-services'
like the code snippet down below.


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


android
// ...


dependencies
// ...


// ADD THIS AT THE BOTTOM
apply plugin: 'com.google.gms.google-services'



And make sure all the library used are as here.



Hope it helps!





I cannot clean project:Error:Could not resolve all files for configuration ':app:debugCompileClasspath'. > Could not find com.google.android.gms:play-services-measurement-base:11.6.2.

@hsbr13 skip it, and follow my code

I had your code snippet already

Aug 12 at 14:36





@hsbr13 did you apply the plugin? Can update your code at the question?
– Angus Tay
Aug 12 at 14:37





@hsbr13 see properly,at app/build.gradle, add the apply plugin to the bottom after dependencies

Add firebase-core to your dependencies block:


firebase-core


implementation 'com.google.firebase:firebase-core:16.0.1'



The Firebase SDK release notes for the June 12 release explain:



Your app gradle file now has to explicitly list
com.google.firebase:firebase-core as a dependency for Firebase
services to work as expected.



It's also safer to list google() first in repository lists:


google()


repositories
google()
jcenter()
...





same error keep happening

Did you also change firebase-auth:11.6.2 to use a new version, e.g. 16.0.2?

firebase-auth:11.6.2


16.0.2

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas...

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right.

Creating a leaderboard in HTML/JS

Image
Clash Royale CLAN TAG #URR8PPP Creating a leaderboard in HTML/JS I'm trying to create a top 10 leaderboard, for now, I've only implemented 3 players, but I'm coming across an issue. My script doesn't seem to be outputting anything on webpage. The purpose of the script is to compare 3 arrays, player1,player2,and player3 solely based off of score. Which is the 2nd index of each array. I want the script to list the players in order of highest score. This method doesn't really seem to be efficient, especially when I'll have to add 7 more players. Could someone suggest perhaps an easier approach, as well as show me why my script wont output the info. Here's the JS function leaderboard() { var player1 = name:"Thomas",date:"01/23/18",score:"201"; var player2 = name:"Michael",date:"03/24/17",score:"943"; var player3 = Name:"Lisa",date:"06/04/18",Score:"79"; if(player1[2]...
