Upgrade to studio 3.0 is crashing my app with dalvik.system.BaseDexClassLoader.findClass

This is just happening after a migration from studio 2.x to studio 3.0 with android 4.4. Android 6 runs fine.
I googled this issue but didn't find crisp response. Just a particular app has this behavior. I have other apps which are fine.
The update process has broken something but what? Why is it impacting android 4.x only?
I tried clean sync, rebuild,restart studio, restart tablet, ...
here is my gradle:
apply plugin: 'com.android.application'

Run the Gradle clean command then do the File -> Invalidate caches & restart. For me it solves the problem

The crash was due to this line in build.gradle:
multiDexEnabled true
Once I removed this line the crash was gone.
I don't know why 2.3 has put this line originally but what is sure is that studio 3.0 made sdk 18 and below crash.

In your case, if you don't need multidex, then disabling it is the right solution. If you need it in the future, follow the instructions linked below to use the MultiDexApplication.
For context, there are two types of multidex, legacy and native. For devices API 21 and above, the platform just reads multiple dex files directly from the APK.
For devices before API 21, there is the multidex support library that patches the classloader to add in the extra dex files as part of an Application class. Anything that can be loaded before this happens needs to be in the main dex, and you need to use MultiDexApplication (or a subclass, or call MultiDex.install(this) from your Application onAtttachBaseContext)
Android studio 3.0 switched to creating the minimal main dex for debug builds, that is, only keeping the smallest set of files in the main dex. This is for build performance and to make these crashes reproducible, rather than it being luck if a class was included in the main dex or not.
In your case, your app fit in one dex in 2.3, but in 3.0 with the new minimal main dex behavior, that class was not in the main dex. However because you are not using the MultiDexApplication, the classloader is never patched, so the classes in the secondary dex file cannot be loaded.
For more information see https://developer.android.com/studio/build/multidex.html#mdex-gradle

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'

Conflicting between Firebase messaging and Content Provider when i use them together

I have an application that share locations between users on Google maps and sorting and retrieving database using content provider and also opening chat messages using firebase messaging but when i combine Firebase messaging and Android content provider together the conflict happens and i found the error below , although when i use content provider or firebase messaging separately they work well and i have outputs from both, but once i combine both i have that message :

Try adding this in your manifest
<application

android:name=".MyApplication">
// ...
</application>
Then make a class.
public class MyApplication extends Application {
#Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
}
