How can I resolve App stuck on Splash Screen

Good day,
My application was working for months now, but all of a sudden it is stuck on splash screen, when using both Android Studio and the live App on Google Play. And I haven't done any change to the app of resent.
Please, anyone help?
Below is the logcat debug result. Thank you

if you didn't changed anything in your app (an we are talking even about app distributed by Google Play) then clearly there is a problem by server side
there is a chance that some network/server side response is just broken, I see you are requesting for something (RequestObject), but also see serverUrl='null', so app may not be configured properly. Also last words of this log is ConnectionBuilder: Response = and... what is the response?
there is no Exception word in block of text posted in question, so app hangs on splash because of wrong logic in code (maybe not aware of some null parameters)
there is also a chance that you are using 3rd party lib connecting to some services (I see Firebase in logs), which is currently deprecated
without line of code all this is guessing...
PS. learn how to post readable logs...

I had the same problem. This is my solution. I hope you will understand.
Situation: How to solve this problem when there is an error code '16:', stuck at the 'Sign In with Google', after we pressed our email at the messagebox not next activity appear but only appear the error.
5.2. To solve this:
5.2.1. Get SHA1 from your project (Android Studio)
5.2.2. Create the API Key and OAuth 2.0 client IDs (Android type). (https://console.cloud.google.com/apis/credentials)
5.2.3. So, the data is set at Google, so get the new Firebase Console google.json at https://console.firebase.google.com/ (at Project Settings). Download it then replace.
5.2.4. Close the Android Studio, open back, then 'Make Project'
5.2.5. Run at the phone. Success!
Refer to this link: google signIn not working in release mode apk android
Extra about google api: https://developers.google.com/maps/documentation/android-sdk/config
(adding extra things for the manifest.xml)

I was also seeing "error code 16" when integrating Google SignIn on Android with Firebase. Still not sure what I was missing but I went back to the beginning and followed this doc:
https://firebase.google.com/docs/auth/android/google-signin
This link is pretty complete. I didn't need to configure anything in Google Cloud console. I did use the info on the Integrating Google SignIn page that the above page links to and got the code and layout for the button.

After struggling for about 48 hrs to solve the firebase google sign-in error 16 credential not matching;
The only thing that solved my problem is to get your web_client_id using "Configure a Google API Console project" through this link https://developers.google.com/identity/sign-in/android/start-integrating#configure_a_project, you should provide the application id from AndroidManifest.xml and sha1 from the signingReport of android studio.
Also, I got different sha1 for each android studio project as to avoid any conflicts in firebase, this by setting debug parameters in signingConfigs {} in android {} in the app build.gradle as follow
android {
signingConfigs {
debug {
storeFile file("path_to_keystore.jks")
storePassword "keystore_password"
keyAlias "key_alias_name"
keyPassword "key_password"
}
}
}
Moreover, I recommend to try firstly google sign in without firebase to give you a positive energy, then secondly go for firebase google sign-in as needed.
Hope this helps every developer facing the same error and save their time.

Firebase Storage - issue in running the android app

I'm working on an android app that uses firebase storage. The app basically uses a few gestures out of which one is used to open the camera. The clicked photo is then saved to firebase storage. The app runs fine on my end and the clicked photo gets stored into firebase. But the issue is that one of my friends is working with me on this app and we are using the same gradle and android version and I have given her the owner rights for this project on firebase console, but despite that, the app on her device doesn't store the image on the firebase. In all, the app opens the camera on her device, the photo is clicked and then the app stops. Can anyone suggest a fix that is missing here???

Unable to write to Firebase Database from my Android application

This is the code I use to connect and write to the database (I want to create a new child node userand assign the value alex to it.
DatabaseReference mDatabase = FirebaseDatabase.getInstance().getReference();
mDatabase.child("user").setValue("alex");
Note: I have followed the correct set-up instructions and have changed the authorisation of read and write to true. The code was working for about a month but now I can't figure out why its not writing to the database.

What am I doing wrong, my firebase database still shows null. However when I add data manually and read via JS it is working correctly.

The errors tell you that you haven't linked Firebase to your project.
03-12 14:43:39.127 12158-12158/? D/FirebaseApp: com.google.firebase.auth.FirebaseAuth is not linked. Skipping initialization.

Use the Firebase Assistant to set it up:
To open the Firebase Assistant in Android Studio:
Click Tools > Firebase to open the Assistant window.
Click to expand one of the listed features (for example, Analytics), then click the provided tutorial link (for example, Log an Analytics event).
Click the Connect to Firebase button to connect to Firebase and add the necessary code to your app.

'Unfortunately, app has stopped' is shown twice on the device and 'Application terminated' in android studio with no error being shown

I am developing an app using Android Studio.
The problem is that app gets crashed twice within few minutes of running it and besides Application terminated. and normal logs no error is shown in the logcat.
Here's complete logcat:

Application terminated.
I tried integrating crashlytics but even it doesn't show any error when the app crashes in this manner.
The question is how will I be able to fix the error if I don't even know what the error is?
Please help me with this.

I think the issue is related to your ad view.
In last line it is showing that ad is not visible.
