I have added SHA key for my project in firebase console. In gradle also upgraded to latest versions.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "com.belleza.mewChat"
        minSdkVersion 16
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled true
            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-v7:23.4.0'

    compile 'com.firebaseui:firebase-ui-database:0.4.1'

    //firebase auth
    compile 'com.google.android.gms:play-services-auth:9.2.0'
    compile 'com.google.firebase:firebase-auth:9.2.0'
}
apply plugin: 'com.google.gms.google-services'

Answer 1

When I set

...
release {
    minifyEnabled true
    ...
}
...

in my build.gradle this solved my problem.

Answer 2

In my case, that error was caused by having an outdated version of Google Play services on my emulator device. The problem was solved by updating Google Play services from the Google Play Store.

Answer 3

this error may also raise if password provided is less than 6 characters
