I was doing this tutorial on Android and Firebase but for some reason when I try to register a new driver it doesn't interact with Firebase at all. Though it does show it's connected to Firebase:
I have downgraded my API to 26 because of this error:
Google Play services out of date. Requires 9256000 but found 9080470.
So I installed Genymotion to solve this issue as advised by contributors on this platform.
But it still doesn't communicate with Firebase. It returns 0 Errors and yet doesn't work.
I've installed GenyMotion but every time I try to run on it's devices it keeps crashing.
public class DriverLoginActivity extends AppCompatActivity {
private EditText mEmail, mPassword;
private Button mLogin, mRegistration;
private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener firebaseAuthListener;
private static final String TAG = "Test";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_driver_login);
mAuth = FirebaseAuth.getInstance();
firebaseAuthListener = new FirebaseAuth.AuthStateListener() {
#Override
public void onAuthStateChanged(#NonNull FirebaseAuth firebaseAuth) {
FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
if(user!=null){
Intent intent = new Intent(DriverLoginActivity.this,
MainActivity.class);
startActivity(intent);
finish();
return;
}
}
};
mEmail = findViewById(R.id.email);
mPassword = findViewById(R.id.password);
mLogin = findViewById(R.id.login);
mRegistration = findViewById(R.id.registration);
mRegistration.setOnClickListener(new View.OnClickListener() {
#Override

final String email = mEmail.getText().toString();
final String password = mPassword.getText().toString();
mAuth.createUserWithEmailAndPassword(email,

});
}
});
mLogin.setOnClickListener(new View.OnClickListener() {

ItI am a learner, any help is appreciated.
I get the same error because I was use Emulator ..
but when I try it in a real device it is working perfectly ..
Hope it works for you too..
Worked for me using these dependencies:
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
//NOT DEFAULT BELOW
compile 'com.firebase:firebase-client-android:2.3.1'
compile 'com.android.support:design:26.1.0'
compile 'com.github.rtoshiro.mflibrary:mflibrary:1.0.0'
compile 'com.google.firebase:firebase-core:11.2.0'
compile 'com.google.firebase:firebase-database:11.2.0'
compile 'com.google.firebase:firebase-auth:11.2.0'
}
Thank you for all the help.
I have the same problem when I use 'com.google.firebase:firebase-auth:11.6.0'
change to 'com.google.firebase:firebase-auth:11.2.0'
`
Try this dependencies:
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.firebase:firebase-client-android:2.3.1'
compile 'com.google.firebase:firebase-database:11.2.0'
compile 'com.google.firebase:firebase-crash:11.2.0'
compile 'com.google.firebase:firebase-auth:11.2.0'
compile 'com.google.firebase:firebase-messaging:11.2.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
had the same issue in my project while running in the emulator but I solved this by using this in Android Studio 3.0.1
app/build.gradle
compile "com.google.firebase:firebase-auth:9.0.2"
build.gradle ( root directory )
classpath 'com.google.gms:google-services:3.0.0'
there setting work for me
Looking at https://github.com/firebase/FirebaseUI-Android/issues/1104. I think this is an acknowledged issue in the SDK that would be resolved in the next 1 or 2 SDK updates. A github user called Samstern posts this -
A fix for this bug has been submitted internally, so this should be
fixed in the next 1-2 Firebase Auth SDK releases depending on the
release cycle.
I am going to close this issue here since there's nothing more
FIrebaseUI can do, thanks for everyone who reported it!
Nonetheless, try the following and see if it works. To repeat what Bob Snyder said - Delete this line from the dependencies block: implementation 'com.google.gms:google-services:3.1.0'. Upgrade your firebase to 11.8.0. So your app's build.gradle should look like something like this.
implementation 'com.google.firebase:firebase-core:11.8.0'
implementation 'com.google.firebase:firebase-auth:11.8.0'
implementation 'com.google.firebase:firebase-messaging:11.8.0'
implementation 'com.google.firebase:firebase-storage:11.8.0'
implementation 'com.google.firebase:firebase-database:11.8.0'
Let me know how that goes.
I solved this by upgrading Google Play Services in the emulator. It was not necessary to change anything in gradle.
For me works change from compile:
com.google.firebase:firebase-auth:11.8.0
to compile:
com.google.firebase:firebase-auth:11.2.0

I started to encounter this error when I upgraded the version of the project to androidx. I also upgraded the firebase sdks. I started getting error "Cannot resolve symbol 'FirebaseInstanceId' " . With this method, I was taking the user's token and printing it to the database. How can I solve this problem?
Manifest :

}
private void updateToken(String refreshToken) {
FirebaseUser firebaseUser = FirebaseAuth.getInstance().getCurrentUser();
DatabaseReference reference = FirebaseDatabase.getInstance().getReference("Tokens");
Token token = new Token(refreshToken);

this.token = token;
}
public Token() {

public String getToken() {

}
public void setToken(String token) {

}
I was rewriting the token code every time the user entered the home page.
MainActiviy :
updateToken(FirebaseInstanceId.getInstance().getToken());
private void updateToken(String token){
DatabaseReference reference = FirebaseDatabase.getInstance().getReference("Tokens");
Token token1 = new Token(token);

try replace your database implementation version 17.0.0 to this version
implementation 'com.google.firebase:firebase-database:16.0.5'
and it will work
I did everything by following the instructions. But mFirebaseRemoteConfig.fetch(cacheExpiration) haven't been working.
But when I changed a version to the earlier in my app build gradle file from
implementation 'com.google.firebase:firebase-config:16.0.0'
to
implementation 'com.google.firebase:firebase-config:11.0.4'
it's become working..
Do you have any idea, what can be the reason of it?

The promlem is in emulator, I guess.. But now I can't find Google Play settings in the emulator's extanded window.. If I'm right, Is there another way to update Google Play Services on emulator?
This is my SDK Settings
with 'Show package details':
Yes, the problem is in emulator. But also I've found out that it's better to check the device for a compatible Google Play services by GoogleApiAvailability.makeGooglePlayServicesAvailable() method.
See the link.
It's my verification method, wich I call at onCreate():
private void checkGooglePlayServices() {
GoogleApiAvailability api = GoogleApiAvailability.getInstance();
int status = api.isGooglePlayServicesAvailable(this);
Log.i("TAG", "AppController checkGooglePlayServices status " + status);
if (status != ConnectionResult.SUCCESS) {
api.makeGooglePlayServicesAvailable(this);
}
}
You need to add:
implementation 'com.google.firebase:firebase-core:16.0.0'
Your app gradle file now has to explicitly list com.google.firebase:firebase-core as a dependency for Firebase services to work as expected.
more info here:
https://firebase.google.com/support/release-notes/android
Faced the same problem. I just replaced the google() by maven { url 'https://maven.google.com' }, then it started working.
Refer the quickstart app here.
I'm trying to register a user in firebase. Here is my code:
App level gradle:
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])

implementation 'com.android.support.constraint:constraint-layout:1.0.2'

androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
compile 'com.google.firebase:firebase-core:11.6.2'
compile 'com.google.firebase:firebase-auth:11.6.2'
}
Project level gradle:
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
classpath 'com.google.gms:google-services:3.1.1' // google-services plugin
My code for register user:
private void registerUser(String name,String email,String password) {
pBar.setVisibility(View.VISIBLE);
mAuth.createUserWithEmailAndPassword(email,password).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if(task.isSuccessful()){
Toast.makeText(getApplicationContext(),"User Created. Please login.",Toast.LENGTH_LONG).show();
}
else {
Toast.makeText(getApplicationContext(),task.getException().getMessage(),Toast.LENGTH_LONG).show();
}
pBar.setVisibility(View.GONE);
}
});
