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 have downloaded ViroCore lib the latest version (virocore-release-v_1_7_2.aar), then I added dependencies below to my build.gradle file
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:25.0.0'
implementation 'com.google.android.exoplayer:exoplayer:r2.2.0'
androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
testImplementation 'junit:junit:4.12'

implementation 'com.amazonaws:aws-android-sdk-cognito:2.2.+'
implementation 'com.amazonaws:aws-android-sdk-cognitoidentityprovider:2.2.+'}
and then wrote to my ViroActivity code below:
private ViroView createGVRView() {
return new ViroViewGVR(this, new ViroViewGVR.StartupListener() {
#Override
public void onSuccess() {
onRendererStart();
}
#Override
public void onFailure(ViroViewGVR.StartupError error, String errorMessage) {
onRendererFailed(error.toString(), errorMessage);
}
}, new Runnable() {
#Override
public void run() {
}
});
}
But when run the app, I always see next Exception:
E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.example.virosample.gvr.ovr, PID: 17304

Anyone knows how to resolve this exception?
I solved this issue. I added to my dependency just viro library, but I must add additionally both sdk-common.aar and core.aar which you can download at the official virocore site.
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Google Play services out of date.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.

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
Where can I find the android support library with ActivityCompat.getReferrer() this function ?
I thought it would be in
my build.gradle looks like this: compile 'com.android.support:support-v4:24.0.1' but its not working.
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
//Google
compile 'com.android.support:appcompat-v7:24.2.1'
compile 'com.android.support:design:24.2.1'
compile 'com.android.support:cardview-v7:24.2.1'
compile 'com.google.android.gms:play-services-base:10.0.1'
compile 'com.google.firebase:firebase-messaging:10.0.1'
compile 'com.android.support:support-v4:24.0.1'
compile 'com.android.support:percent:24.0.0'
}
I am trying to access ActivityCompat.getReferrer() from a activity that extends AppCompatActivity in android.support.v7.app package but I can't find this method
Only compile 'com.android.support:appcompat-v7:24.2.1' is enough for that method as it is a method of ActivityCompat. Please use same versions' of libraries from support library.
Java code sanple
public class SplashActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
Uri uri = ActivityCompat.getReferrer(SplashActivity.this);
if (uri != null)
Toast.makeText(SplashActivity.this,uri.toString(),Toast.LENGTH_SHORT).show();
}
}
Background: I'm trying to make a simple with RxPermissions .. I created a new project with the bellow code/setup but when I launch the app I got a dialog with the message "unfortunately package installer has stopped"
gradle.build
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:24.1.1'
compile 'com.tbruyelle.rxpermissions:rxpermissions:0.7.0#aar'
compile 'io.reactivex:rxandroid:1.2.1'
// Because RxAndroid releases are few and far between, it is recommended you also
// explicitly depend on RxJava's latest version for bug fixes and new features.
compile 'io.reactivex:rxjava:1.1.6'
}
MainActivity.java
public class MainActivity extends Activity {
#Override protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Must be done during an initialization phase like onCreate
((Button) findViewById(R.id.button)).setOnClickListener(new View.OnClickListener() {
#Override public void onClick(View view) {
RxPermissions.getInstance(MainActivity.this)
.request(Manifest.permission.CAMERA)
.subscribe(new Action1<Boolean>() {
#Override public void call(Boolean aBoolean) {
}
});
}
});
}
}
I forgot to declare the permission Manifest.permission.CAMERA in the manifest.
