firebase createUserWithEmailAndPassword is not working in android

Question

I'm trying to use the createUserWithEmailAndPassword method to create users but not able to do so. The OnAuthenticate method is being called but user object is null and no user is being created inside firebase console. Here is my code, which is the one available online as well.

MAinActivity.java

private static FirebaseAuth mAuth;
private static FirebaseAuth.AuthStateListener mAuthListener;
private static String TAG = "RegisterDEbug";
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //setContentView(R.layout.activity_main);
    mAuth = FirebaseAuth.getInstance();
    mAuthListener = new FirebaseAuth.AuthStateListener() {
        @Override
        public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
            waitForDebugger();
            FirebaseUser user = firebaseAuth.getCurrentUser();
            if (user != null) {
                // User is signed in
                Log.d(TAG, "onAuthStateChanged:signed_in:" + user.getUid());
            } else {
                // User is signed out
                Log.d(TAG, "onAuthStateChanged:signed_out");
            }
            // ...
        }
    };
    mAuth.addAuthStateListener(mAuthListener);
    mAuth.createUserWithEmailAndPassword("[email protected]", "corrfecthorsebatterystaple")
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    waitForDebugger();
                    Log.d(TAG, "Authentication successful");
                    if (!task.isSuccessful()) {
                        //Toast.makeText(this, "Authentication failed.",  Toast.LENGTH_SHORT).show();
                    }
                }
            });
}

app.properties

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0'

        classpath 'com.google.gms:google-services:3.0.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

app.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "com.pt.reg"
        minSdkVersion 10
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            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.google.android.gms:play-services:9.0.2'
    //compile 'com.google.android.gms:play-services-auth:9.0.2'

    compile 'com.google.firebase:firebase-core:9.0.2'
    compile 'com.google.firebase:firebase-auth:9.0.2'
}

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

Note - I have tried web solution from firebase for creating a user which works fine.

Answer 1

I had this problem too. The password I was testing the app with was just too short. I extended it to a longer password and it worked. You have to meet google's password complexity standards.
