After adding library gradle haven't synced properly so it's showing the error, "Didn't find class '.MainActivity' ":
The main problem is some gradle files have same internal files like:-
implementation files('src/libs/okhttp-3.11.0.jar')
implementation files('src/libs/okio-1.14.0.jar')
or
implementation files('src/libs/commons-lang3-3.9.jar')
implementation files('src/libs/commons-lang3-3.9-sources.jar')
implementation files('src/libs/commons-lang3-3.9-tests.jar')
so it's not syncing successfully ,
Or second option is to use gradle versions like
implementation("com.squareup.okhttp3:okhttp:4.2.2")
implementation 'com.github.apache:commons-lang:LANG_3_8_1_RC1'
and put version according to your need...
The main problem is ClassNotFoundException so check on this link there have given many solution. use it and see what work with your project.

My Android Studio's app collapses when I use TabLayout, how can I fix it?

I am trying to use TabLayout in my AS project. When I run the app on the emulator the app collapse immediately. If I remove the TabLayout view the app runs appropiriately.
I am using androidx.
As in the answers to this question, I tried to add
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:your_api_version_number.0.0'
compile 'com.android.support:design:+'
to the dependencies and I also tried to add
implementation 'com.android.support:support-v4:22.2.0'
implementation 'com.android.support:design:22.2.0'
to the dependencies. Both solutions did not help me.
How can I use TabLayout appropriately?
Here's the code:
<?xml version="1.0" encoding="utf-8"?>

You're targeting android 10, hence the support library's not working. There is no version 29 of the support library since it was included in the androidX packages. you can remove the references to the support library and replace them with the following dependency in order to use the TabLayout:
remove this:
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:29.0.2'
compile 'com.android.support:design:+'
replace it with this:
implementation 'com.google.android.material:material:1.0.0'
EDIT (after logcat error): Please note that once you start using the material dependency and AndroidX, you need to be declaring your TabLayout like this: com.google.android.material.tabs.TabLayout and not like this: android.support.design.widget.TabLayout

Unable to show layout preview and InflateException after migrated to Android X

This morning I decided to migrate all app to Android X to use some new feature, but I got several problems, most of it in these three layout, (activity_main.xml, app_bar_main.xml, content_main.xml)
When I run the app I got this errors

about this error No original dex files found for dex location I tried the solution in this question1, question2 but not working

CTRL + Shift + F and found all CoordinatorLayout.
Then check if CoordinatorLayout elements has this signiture in xml files: androidx.coordinatorlayout.widget.CoordinatorLayout

Use this material design library and make sure all of your widgets are androidx
implementation 'com.google.android.material:material:1.1.0-alpha04'
The recyclerview and navigationView are not part of androidx material design it should be :- ( you are using older design version of recyclerview and NavigationView )
<androidx.recyclerview.widget.RecyclerView
.....
.....
&&
<com.google.android.material.navigation.NavigationView
.....
.....
Edit
Make sure you upgrade every widget to androidx .
The appbar widget should be
<com.google.android.material.appbar.AppBarLayout

And I think my build.gradle is needed so here is my build.gradle(Project: test):

With that error, the app crashes.
I think there could be anything wrong with the firebase SDK, but can't figure it out?
Please help me to fix this. I didn't find a way to fix it, for a long time.:(
EDIT:
After updated everything to the newest version and added:
multiDexEnabled true
...everything works fine. But now I have the Problem, why I downgraded the versions finally. Please have a look at my question: I don't get a response:
Updating code after firebase 16.0.+ update
When I could fix that everything would be fine.

I see a whole mess of problems in your build.gradle.
The first category of issues is that most of your dependencies are pretty outdated.
The Android API 27 support libraries are on 27.1.1, not 27.0.2.
firebase-firestore is on 17.1.2, not 15.0.0.
firebase-ui-firestore is on 4.2.1, not 2.1.1.
glide is on 4.8.0, not 3.7.0.
Dependency versions should be up-to-date in general, but absolutely must be up-to-date if they're from Google. Otherwise you run into exactly the type of error you have.
The second problem is that you implement firebase-firestore twice, once with implementation and again with api. Remove one or the other.
A handy tip: if a dependency is highlighted in yellow, that means it's outdated! Click the text, hit Alt+Enter and choose the option to update it to the latest version.

Error inflating class android.support.constraint.ConstraintLayout. Release only

I've been developing a project for 2 months and it works in debug mode.
Today I created a release apk and I have an error on all devices:
android.view.InflateException: Binary XML file line #0: Error inflating class android.support.constraint.ConstraintLayout
Caused by: java.lang.NoClassDefFoundError: Failed resolution of: Landroid/support/constraint/solver/widgets/ConstraintWidgetContainer;

Caused by: java.lang.NoClassDefFoundError: Class not found using the boot class loader; no stack available
Please help!
'com.android.support.constraint:constraint-layout:1.0.0'

To me it happens copying an existing class from a non androidx project into an androidx one.
I had to change:
android.support.constraint.ConstraintLayout
in the xml layout
into:
androidx.constraintlayout.widget.ConstraintLayout
and it solved the issue.

I had to add multidex support:
build.gradle:
android {
...
defaultConfig {
...
multiDexEnabled true
}
}
and:
dependencies {
...
implementation 'com.android.support:multidex:1.0.3'
...
}

Try this
select file and choose invalidate caches / restart
if not worked then update it to
compile 'com.android.support.constraint:constraint-layout:1.0.2'

setting
dexOptions {
preDexLibraries false
}
solved the problem
