For latest version (3.4 or higher) of Android Studio
Instead of
import android.support.v7.app.AppcompatActivity
Use this
import androidx.appcompat.app.AppcompatActivity
In MainActivity.java or in main java file

I think you should Migrate to AndroidX if you want to use 'com.google.android.gms:play-services-auth:17.0.0' (17.0.0 version) or if you don't want to migrate androdiX use version 16.0.0 implementation 'com.google.android.gms:play-services-auth:16.0.0'

The c in AppcompatActivity must be in uppercase:
import androidx.appcompat.app.AppCompatActivity

The error doesn't happen with firebase crashlytics dependency version 17.1.1 and below.
I have already tried:
Rebuilding Project
Cleaning Project
Invalidating Cache and Restarting
The solution to this problem was that FirebaseInstanceId was depreciated. This means that it was removed from the library.
You can find more information about it here: https://firebase.google.com/docs/reference/android/com/google/firebase/iid/FirebaseInstanceId

I know this is the old question, but I saw such a problem after removing jcenter() from repositories in gradle file:
repositories {
google()
jcenter()
}
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
this worked for me ,i had to add jitpack.io
Try this
compile 'com.amitshekhar.android:android-networking:1.0.2'
When using it with Jackson Parser
implementation 'com.amitshekhar.android:jackson-android-networking:1.0.2'
When using it with RxJava
implementation 'com.amitshekhar.android:rx-android-networking:1.0.2'
When using it with RxJava2
compile 'com.amitshekhar.android:rx2-android-networking:1.0.2'
add this line in gradle.properties:
# Automatically convert third-party libraries to use AndroidX
android.enableJetifier=true

Realm annotation processor error not picking up

I have been getting the error about the annotation processor for the Realm library fails to load, am I missing something? Where do I add it in or what should I do?
This is the error I get:

Please assist!
Follow the instructions as mentioned in realm docs
Step 1: Add the class path dependency to the project level build.gradle file. (Which you refer to as Project gradle in question)
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath "io.realm:realm-gradle-plugin:5.4.1"
}
}
...
Step 2: Apply the realm-android plugin to the top of the application level build.gradle file. (Which you refer to as App gradle in question)
apply plugin: 'realm-android'
apply plugin: 'com.android.application'
android {
compileSdkVersion 27
defaultConfig {
applicationId "com.version.crt.myapplication"
minSdkVersion 22
targetSdkVersion 27
versionCode 1
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'])
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation 'com.android.support:design:27.1.1'
implementation 'com.android.support:recyclerview-v7:27.1.1'
implementation 'com.android.support:design:27.1.1'
implementation 'com.android.support:cardview-v7:27.1.1'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}
Add below two line
implementation 'io.realm:realm-android:0.82.1'
annotationProcessor 'io.realm:realm-android:0.82.1'
instead of just one line
implementation 'io.realm:realm-android:0.82.1'
should resolved the problem.

Data Binding andGoogle Services plugin not work together

I use firebase on my project. So at the bottom of my app/build.gradle file is
apply plugin: 'com.google.gms.google-services'.
When I want to activate Databinding with
dataBinding {enabled true}
I'm getting the error;
"Gradle sync failed: Can not change dependencies of configuration ': app: api' after it has been included in dependency resolution."
As a result, when multiple plugins are added, DataBinding gives an error. I still can not find a solution.
How to use data binding in a project using Google Services?
Android Studio 3.1.2

The problem is in the gms version. The problem has been resolved with version 4.0.1
// classpath 'com.google.gms:google-services:3.3.1'

}
}
dataBinding {
enabled = true
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
//noinspection GradleCompatible
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
// add firbase
implementation 'com.google.firebase:firebase-messaging:15.0.2'
}
2. Project level gradel file.
buildscript {
repositories {

}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.2'
classpath 'com.google.gms:google-services:3.2.0'
