Please help to solve.
Also i have ads in my game. so do i need to provide internet permission.?

Your application supports only Android Pie (9) and Android Q(10) only.
To support vast number of devices, please change minSdkVersion to 23 and update target version to latest available i.e. 30.
Yes, Internet permission is required to show the Ads.

i test every solution in stackoverflow and google search but anyone help me.
can anyone help to solve this error ?!?!?!?

You are using
implementation 'com.google.firebase:firebase-messaging:19.0.1'
Firebase migrated to AndroidX in the latest release.
It means that you are using both, support libraries and androidx libraries.
You can:
migrate to androidx as described below
downgrade your firebase dependencies (but it is not a real solution because you have to migrate sooner or later)
You can check the official release notes:
Warning: This release is a MAJOR version update and breaking change.
The latest update to Google Play services and Firebase includes the following changes:
Migration from Android Support Libraries to Jetpack (AndroidX) Libraries. Libraries will not work unless you make the following changes in your app:
Upgrade com.android.tools.build:gradle to v3.2.1 or later.
Upgrade compileSdkVersion to 28 or later.
Update your app to use Jetpack (AndroidX); follow the instructions in Migrating to AndroidX.

Application crashing when another activity is added

I am creating an android application that logs in the user via email authentication through firebase and on successful login the app will shift to another activity.
Now the problem is while the single activity for login is working fine but as soon as I add another activity on which it has to jump and try to run again then this error
NoClassDefFoundError: Failed resolution of:
Landroid/view/View$OnUnhandledKeyEventListener;
comes up and the application automatically closes.
I have tried many different options but none of them works. Have restarted my pc, invalidated the cache but still no luck.

The manifest file seems fine. If everything in LoginActivity, MainActivity and xml are correct I suggest you to delete the build folders - because you have already invalidate the cache.
project-folder/build
project-folder/app/build
If it still don't work I suggest you to comment everything on those classes and start uncommenting while testing.

java.lang.ClassNotFoundException: Didn't find class "com.google.android.gms.measurement.AppMeasurement" on path: DexPathList

My app was running well but it is crashing now. I started getting warnings even though I am not integrating with firebase. Now I think that I can not solve this problem. I tried every possible solution available on stackoverflow. Also, I am using viewpager in my code if that helps.

I think this issue is similar with How to enable multidexing with the new Android Multidex support library
Add implementation "com.android.support:multidex:1.0.1" in your build.gradle's dependencies ( implementation can be replaced with compile );
Add a custom application extends from Application. Add code as below:
override fun attachBaseContext(base: Context?) {
super.attachBaseContext(base)
MultiDex.install(this)
}
Add your custom application in AnroidManifest.xml as android:name=".CustomApplication"

You should use compile 'com.google.firebase:firebase-ads:11.2.0'
instead of compile 'com.google.android.gms:play-services-ads:11.2.0'

Firebase ads: java.lang.InstantiationError: com.google.android.gms.internal.zznv

Adding AdMob to my Android app drives me mad :o
Firebase is already running (auth, db, ...).
I added gradle dependency for ads too.
I followed Google instructions exactly.
I have two issues:
The AdView Container in my xml layout file cannot be rendered in the preview. It says:
The following classes could not be instantiated: com.google.android.gms.ads.AdView
Exception Details java.lang.NoClassDefFoundError: Could not initialize class com.google.android.gms.internal.zzeh   at com.google.android.gms.internal.zzez.  at com.google.android.gms.internal.zzez.  at com.google.android.gms.internal.zzez.  at com.google.android.gms.ads.BaseAdView.  at com.google.android.gms.ads.AdView.  at java.lang.reflect.Constructor.newInstance(Constructor.java:423)   at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:727)
If I try to initialize ads in my code, it crashes in this code-line:

The size and number of included libraries requires Multidex. You say you tried to enable it. Note that three steps are required, including a change to the manifest.
Also, when using version 10.0.1 of the Firebase libs, you must use version 1.0.1 of Firebase UI:
compile 'com.firebaseui:firebase-ui:1.0.1'
The Firebase UI docs contains a table of compatible versions.

<uses-permission android:name="android.permission.INTERNET"/>
put this in menifest.
