Cannot able to use StorageRefrence in my android app

I am using Firebase for uplodaing the images but whenever i am using StorageReference then it saying cannot able to resolve this symbol i have tried to add dependency of storage but it is also not adding and giving me the error.
Please tell how can i use StorageReference
my build.gradle(app):
apply plugin: 'com.android.application'

}
}
allprojects {

}
}
task clean(type: Delete) {

}
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.

How to fix gradle when this error appear?

I started a new project and put fire-base cloud:
apply plugin: 'com.android.application'
apply plugin: 'android-apt'
android {
compileSdkVersion 28
buildToolsVersion "28.0.3"
defaultConfig {
applicationId "android.example.com.squawker"
minSdkVersion 16
targetSdkVersion 28

versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
//noinspection GradleCompatible
implementation 'com.android.support:appcompat-v7:28.0.0'
testImplementation 'junit:junit:4.12'
// RecyclerView
implementation 'com.android.support:recyclerview-v7:28.0.0'
// Schematic dependencies for ContentProvider
apt 'net.simonvt.schematic:schematic-compiler:0.6.3'
implementation 'net.simonvt.schematic:schematic:0.6.3'
// Preferences Dependencies
implementation 'com.android.support:preference-v7:28.0.0'
// Firebase dependency
implementation 'com.google.firebase:firebase-messaging:17.3.4'
}
// Apply the Google Services plugin. Make sure to add the google-services.json file in the app
// folder. You download it from the Firebase console
apply plugin: 'com.google.gms.google-services'
and this error apeared:
WARNING: API 'variant.getJavaCompile()' is obsolete and has been replaced with 'variant.getJavaCompileProvider()'.
It will be removed at the end of 2019.
For more information, see https://d.android.com/r/tools/task-configuration-avoidance.
To determine what is calling variant.getJavaCompile(), use -Pandroid.debug.obsoleteApi=true on the command line to display a stack trace.
Affected Modules: app

This probably because of apt plugin which is already obsolete. So, you need to remove the following:
apply plugin: 'android-apt'
then change the following:
apt 'net.simonvt.schematic:schematic-compiler:0.6.3'
with:
annotationProcessor 'net.simonvt.schematic:schematic-compiler:0.6.3'

Similar to API 'variant.getExternalNativeBuildTasks()' is obsolete and has been replaced with 'variant.getExternalNativeBuildProviders() Happy Coding!

Android Studio Failed to resolve: com.android.support:appcompat-v7.28.0.0

I am getting this error, Failed to resolve: com.android.support:appcompat-v7.28.0.0 I have been looking on here and tried changing it to other variations of that line but so far no luck, why do I keep getting this error?

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

The issue is with the appcompat-v7 dependency that you have added to the build.gradle.
Change implementation 'com.android.support:appcompat-v7.28.0.0' to implementation 'com.android.support:appcompat-v7:28.0.0'
Notice the : between appcompat-v7 and 28.0.0 that separates the artifact name and the version.

If we don't consider the typo in :
implementation 'com.android.support:appcompat-v7.28.0.0'
Change it to:
implementation 'com.android.support:appcompat-v7:28.0.0'
Then, you probably should use the latest version for the Firebase dependencies to avoid those Please fix the version errors:
implementation 'com.google.firebase:firebase-auth:16.0.4'
implementation 'com.google.firebase:firebase-core:16.0.4'
implementation 'com.google.firebase:firebase-database:16.0.3'
Then rebuild the project. Also, remember to use latest gradle to avoid couldn't found such dependency or etc.
Inside build.gradle of the project (inside your project root directory):
dependencies {
classpath 'com.android.tools.build:gradle:3.2.0'
// replace it with the 3.2.0 version
...
classpath 'com.google.gms:google-services:4.1.0' // update this too
}

Failed to resolve: com.android.support:appcompat-v7:28.+ , Error: more than one library with package name 'android.support.graphics.drawable'

I'm new to Android Studio, I tried everything to solve this problem "Failed to resolve: com.android.support:appcompat-v7:28.+ "
I tried to clean project , invalidate cash/restart and removing .idea and still the same
I'm using android studio 2.2.1 for a learning reason , and I updated it to android studio 3 and there a multiple rendering problems so I returned back to version 2.2.1
I tried to add
maven {
url 'https://maven.google.com/'
name 'Google'
}
So,It stuck with another problem
"Error:Execution failed for task ':app:processDebugResources'.
> Error: more than one library with package name 'android.support.graphics.drawable'"
Error Photo
Finally I tried to change "appcompat-v7:28.+" to "appcompat-v7:27" and it' works but still tell me that i should use the same library to avoid mistakes
This is my Gradle code:
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
buildToolsVersion "28.0.1"
defaultConfig {
applicationId "com.example.aimlive.myapplication"
minSdkVersion 15
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:28.+'
testCompile 'junit:junit:4.12'
}

Replace 'com.android.support:appcompat-v7:28+' by 'com.android.support:appcompat-v7:28.0.0'
and add below dependencies
implementation 'com.android.support:support-v4:28.0.0'
implementation 'com.android.support:support-media-compat:28.0.0'
implementation 'com.android.support:animated-vector-drawable:28.0.0'
implementation 'com.android.support:customtabs:28.0.0'

try adding this to your code:
repositories {
jcenter()
maven { // <-- Add this
url 'https://maven.google.com/'
}
}
Update: Now you moved on to another error:
Error: more than one library with package name 'android.support.graphics.drawable ...
To fix this, you need to change compile to implementation in dependencies part.

if you are using
compileSdkVersion 28
add in your dependencies below code
implementation 'com.android.support:appcompat-v7:28.0.0-alpha'
this is the link

Try this one, hope it is working
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'com.android.support:appcompat-v7:28.0.0'

dependencies
classpath 'com.android.tools.build:gradle:3.1.4'

Try this code, hope it will be working. Thanks

I found that 'com.android.support:animated-vector-drawable' and 'com.android.support:support-vector-drawable' have a same package name in support library version 28.0.0. Normally this does not make the problem.
But if you have the following line in gradle.properties
android.uniquePackageNames = true
you will see the error
more than one library with package name 'android.support.graphics.drawable'"
If you should use the uniquePackageNames option, use androidx instead of support library 28.0.0.

In case someone like me stuck for hours and find out the you have to check the maven dependency "com.android.support:appcompat-v7:28.0.0". remove the "+" sign as gradle does not like it for unpredictable versions. so i had to check the maven repository and found that i was compiling with 29 and 29 does not exist. please check below link

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'
