Unable to authenticate with Firebase



I am trying to sign in to Firebase on an emulator using credentials I added via the console.



Here is the code:


val auth = FirebaseAuth.getInstance()

auth.signInWithEmailAndPassword(email, password)
.addOnCompleteListener(this) task ->
if (task.isSuccessful)
// ...
else
// ...




The OnCompleteListener callback is never triggered.


OnCompleteListener



I have followed the guidelines from the Firebase documentation



Any idea what I am doing wrong?



Gradle file - project:


buildscript
ext.kotlin_version = '1.2.60'
repositories
google()
jcenter()

dependencies
classpath 'com.android.tools.build:gradle:3.1.3'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

classpath 'com.google.gms:google-services:4.0.2'



allprojects
repositories
google()
jcenter()



task clean(type: Delete)
delete rootProject.buildDir



Gradle file - app


apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android
compileSdkVersion 27
defaultConfig
applicationId "..."
minSdkVersion 23
targetSdkVersion 27
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

buildTypes
release
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

@345 Have you tried to log task.getException() in the else part of your if (task.isSuccessful) statement, to actually see what the problem is?

task.getException()


if (task.isSuccessful)

Is your email or password are valid?



You can add 'addOnFailureListener' to see what really happened.


auth.signInWithEmailAndPassword(email, password)
.addOnCompleteListener(this) task ->
if (task.isSuccessful)
// ...
else
// ...

).addOnFailureListener(new OnFailureListener()
@Override
public void onFailure(@NonNull Exception e)
Toast.makeText(context, e.getMessage(),Toast.LENGTH_SHORT).show();

);





The credentials are valid. onFailure is not firing either.

Or you have to update your firebase-auth dependencies to newer version. Now is 16.0.2

Did you have added internet permission? <uses-permission android:name="android.permission.INTERNET" />
– Lipondevf

Yeah the permission is in the manifest.

Try to add the following dependency in the build.gradle file:-


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



And I also recommend you to use the latest firebase dependencies.





I have added the core dependency and updated the others but the problem persists.

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

Dynamically update html content plain JS

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. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

How to determine optimal route across keyboard

Image
Clash Royale CLAN TAG #URR8PPP How to determine optimal route across keyboard I'm trying to automate the typing process in a video game. Players are given an on-screen QWERTY keyboard layout that they can navigate with the control stick (up, down, left, right) in order to select a letter to type. I was wondering if there was a module for Python (or some other resource I could explore) that would help my program find a path across the keyboard as it types each letter in a given message. In other words, if the first letter typed was "A" and the next letter was "B", the module would know that the program should move 1 space down on the keyboard and 4 spaces to the right. Currently, I have the program resetting to the "G" key after each letter is typed (allowing me to use fixed-directions as the program parses each character in the desired message). As you can imagine, this is quite inefficient and defeats the purpose of automating the typing in the fir
