Can't implement firebase dependencies on my android app

i'm developing an Android Studio App and trying to create a user register activity. I already added firebase into the project but when i try to add the firebase database dependencies, the app crashes instantly and not a single error is reported. However, when i remove the 3 implements from the build gradle, it runs correctly. Here i leave both build gradle codes. Thanks.
Build gradle project:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.6.4'
classpath 'com.google.gms:google-services:4.3.8'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
Build gradle app (this works properly):
apply plugin: 'com.android.application'

SOLVED
The problem just was that i was running an old Android Studio version. I updated Android Studio and checked the gradle versions and now it's all working properly, thanks.

When you use firebase-bom dependency, you no need to mention version for firebase-database and other firebase library.
firebase-bom will choose right version for you or if you want particular version of firebase remove firebase-bom.so add dependency like below
// Import the BoM for the Firebase platform
implementation platform('com.google.firebase:firebase-bom:28.0.1')
// When using the BoM, you don't specify versions in Firebase library dependencies
implementation 'com.google.firebase:firebase-auth'
implementation 'com.google.firebase:firebase-core'
implementation 'com.google.firebase:firebase-database'

Ksoap2 Library to android studio Error message, how to fix?

I an trying to import Ksoap2 library in android studio using .jar file version 3.6.4. I have successfully implemented the jar file to android studio. However, on the module app activity when I try to import e.g. import "org.ksoap2.SoapEnvelope;", it gets and error it shows following results:
Execution failed for task ':app:checkDebugAarMetadata'.
Could not resolve all files for configuration ':app:debugRuntimeClasspath'.
Could not find com.google.code.ksoap2-android:ksoap2-android:3.6.4.
Searched in the following locations:

Possible solution:
Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html
Also the imports library have error, please see the pic:
Here is the Build.gradle module code:
buildscript {

}
Please help me, I been stuck here for a long time. How to fix the error and how can I implement the Ksoap2 library properly. Thanks

There doesn't seem to be a 3.4.3 version of that library. There's a 3.4.0. And the newest is 3.6.4. You're going to need to use one of those. I'd move to 3.6.4 as 3.4.0 is over 5 years old, and likely lacks security updates.

Remove the dependencyResolutionManagement block from the setting.gradle file to have your project work the old way.
Related issue: Build was configured to prefer settings repositories over project repositories but repository 'maven' was added by build file 'build.gradle'

Cannot able to use StorageRefrence in my android app

Please tell how can i use StorageReference

Please tell what is wrong why i am not able to use StorageReference.

If you are planning on using the Storage Bucket feature from Firebase I notice you are missing some implementations in your App Gradle:
implementation 'com.google.firebase:firebase-storage:19.1.1'
implementation 'com.google.firebase:firebase-auth:19.3.1'
You might not need the second one, but i would recommend authentication anyway. Go ahead and add these into your dependencies, that should solve the issue. If it persists let me know and I'll give it a second look.
Also ensure that you have connected your app to your Firebase project...
In android studio, if you go to tools(top bar) > FireBase > Storage it will guide you through the installation, and ensure that you have all the dependencies you need.

Gradle sync failed: All firebase libraries must be either above or below 14.0.0

I've been going at this for a while now, and it's driving me insane. I've looked through a few existing Stack Overflow questions, but nothing has worked. I keep getting this error whenever I add the last line, which I need for my AdMob ad units. People seem to solve this issue by changing the version number for this line to 15.0.0, but, as you can see, I've already done this. Please help, if you can. Also, this isn't even the first time I've worked with ad units.

Update the following classpath dependency in your top-level build.gradle:
classpath 'com.google.gms:google-services:4.0.1'
Only newer versions of this plugin understand that the new Firebase dependencies no longer all have to be at the same version.
Read this for more information.

Upgrade your firebase dependencies to latest version, by changing your dependencies to this:
implementation 'com.google.firebase:firebase-database:16.0.1'
implementation 'com.google.firebase:firebase-auth:16.0.2'
implementation 'com. google.firebase:firebase-core:16.0.1'
And in your project level Gradle file, increment your Google services plugin to 4.0.0

Change this:
implementation 'com.google.firebase:firebase-database:12.0.1'
implementation 'com.google.firebase:firebase-auth:12.0.1'
compile 'com.google.firebase:firebase-core:12.0.1'
into this:
implementation 'com.google.firebase:firebase-database:16.0.1'
implementation 'com.google.firebase:firebase-auth:16.0.2'
implementation 'com.google.firebase:firebase-core:16.0.1'

Getting error "package lombok doesn't exist" with Android Studio 3 RC2

I am getting the following error when trying to compile the project:
error: package lombok does not exist
And others stating that all the annotations from it can't be found.
I don't see errors in code before compiling and I didn't have this error while I was using Android Studio 3 RC1.
Here are my gradle scripts:
Project level:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.0-rc2'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

defaultConfig {

}

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

compileOnly 'org.projectlombok:lombok:1.16.18'
annotationProcessor 'org.projectlombok:lombok:1.16.18'
compile group: 'com.github.javafaker', name: 'javafaker', version: '0.13'
}
I've got modules too, but I think it isn't important.

I hope it is because of compileOnly annotation. Here is the doc:
blog.gradle.org/introducing-compile-only-dependencies
Dependencies required at compile time but never required at runtime, such as source-only annotations or annotation processors;
Dependencies required at compile time but required at runtime only when using certain features, a.k.a. optional dependencies;
Dependencies whose API is required at compile time but whose implementation is to be provided by a consuming library, application
or runtime environment.

It might be related to jdk9. I know that the combination of IntelliJ, lombok 1.16.18 and jdk9 currently doesn't work. But that does not explain your error message. We expect that we can release 1.16.20 within a few days (maybe tonight) that addresses this problem.
Disclosure: I am a lombok developer.
