NoClassDefFoundError: Failed resolution of: Lcom/google/android/gms/common/internal/zzx

I am using
pub.devrel:easygoogle:0.2.5
and
com.google.firebase:firebase-core:16.0.1
I am making a simple notification app which sends notification from FCM.
I am following this but at runtime i am getting error

I have added build gradle file for more details. i extended EasyMessageService for Notifications.
if any more details is required please let me know.
How can it be resolved?
Thanks in advance.

I had also like this problem. I had an old version google and other services such as google service 1.5.0-beta2 Wanted to run on android 10 devices and gave me an error.
Didn't find class "com.google.android.gms.common.internal.zzx"
Then I updated all libraries to the latest version. Then worked.

I am trying to do some experiments with Instant Apps Documentation: Android Instant Apps
Native Android apps, without the installation. I have followed steps which are covered on official docs. I have created emulator Nexus 5X to test instant apps features.
So, I have created two features in my project, which is much similar just kinda of demo to see how instant apps works. It was working well on one feature, now after when I created one more feature, now I have two features which in turns crashing my application.

Can anyone suggest what I am doing wrong ?

It looks like the actual activity package doesn't match what you have in your manifest file of the feature that contains MainActivity. It's a common error when refactoring activities into new packages and not using relative paths for activities in the manifest. Fully qualify the path to be absolutely sure
<activity android:name="com.williams.instantappdemo.feature.MainActivity"/>
Inspect the the apk file (build/outputs/apks) using Apk Analyzer to see if it has com.williams.instantappdemo.feature.MainActivity in that exact package.
You can also use the Merged Manifest view to inspect your final manifest (app module) to verify everything is in order.
Also, add application project(":app") to the base feature module so that it uses applicationId defined in your app module to package your app/instant app
Update:
Using the techniques described above, I investigated the merged manifests and found an issue. The build plugin ignored the numbers in the module name (feature1) so both features ended up having the same name. This caused a bunch of issues including the ActivityNotFound error. Renaming the feature1 module to featureOne resolved the issue.

I was working with some libraries so I had to edit Gradle settings. Since my app wasn't working, I restored it with Local history in Android studio but It still doesn't work. Errors returned are reported here

You may have updated to AndroidX support library and the layout is referencing the old ConstraintLayout version. So you have to update the android.support.constraint.ConstraintLayout tags to androidx.constraintlayout.widget.ConstraintLayout in your layout XML.

Changes you have made earlier corrupted your Gradle File (the module one).
It should look like this:
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "***" /*Your package name*/
minSdkVersion 15
targetSdkVersion 25
versionCode 5
versionName "1.4"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
vectorDrawables.useSupportLibrary = true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
repositories {
jcenter()
maven { url "https://jitpack.io" }
}
dependencies {
//Your Dependencies
//Don't forget to add dependency of constraint-layout
compile 'com.android.support.constraint:constraint-layout:1.0.2'
}
Add dependency for constraint-layout.
See Code
NOTE : compile has become obsolete and replaced with 'implementation'
keyword so replace 'compile' with 'implementation'
so the code will be
dependencies {
//Your Dependencies
//Don't forget to add dependency of constraint-layout
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
}
UPDATE: If you have upgraded to AndroidX now. Then you need to use androidx.constraintlayout.widget.ConstraintLayout instead of android.support.constraint.ConstraintLayout

use androidx.constraintlayout.widget.ConstraintLayout replace android.support.constraint.ConstraintLayout, then it worked

If you updated your project to Androidx
Then Change this dependency.
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
to
implementation 'androidx.constraintlayout.widget.ConstraintLayout:1.0.0'
This will work.

I am using android studio 2.3 hence gradle version is gradle-3.3-all.zip

I faced the same issue today, I have currently downgraded my gradle version and the generated debug apk works just fine, Feel like it might be an issue with the gradle version, will Update on this answer if i find with the actual issue.
But currently downgrading gradle from 2.3.0 to 2.2.0 seems to fix the issue.

I had the same crash with the debug apk of one of my apps. The release version (signed with release key) worked.
My app uses multidex.
I ended up disabling Instant Run in Android Studio (File -> Settings -> Build -> Instant Run) and after a rebuild the debug apk worked as well!
Found this solution here:
