I have made no changes to the template app generated by Android Studio.

Why doesnt the generate template app start cleanly?

I tried migrating to androidX, however the issue remains exactly the same.

Why cant Android Studio generate a "clean" template application?

My gradle files resemble this:-

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.0'


        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

====

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.manacle.secondmanacle"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.0.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.0-alpha2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.0-alpha4'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha4'
}

Add this to gradle will resolve the issue, works for me:

implementation 'androidx.appcompat:appcompat:1.3.0-alpha02'

Please note 1.2.0 even doesn't work

I solved a similar issue

Rejecting re-init on previously-failed class java.lang.Class<androidx.core.view.ViewCompat$2>: java.lang.NoClassDefFoundError: Failed resolution of: Landroid/view/View$OnUnhandledKeyEventListener;
 
Caused by: java.lang.ClassNotFoundException: Didn't find class "android.view.View$OnUnhandledKeyEventListener"

Adding dependency in build.gradle (app level)

Got similar issue with androidx dependencies as like

Rejecting re-init on previously-failed class java.lang.Class<androidx.core.view.ViewCompat$2>: java.lang.NoClassDefFoundError: Failed resolution of: Landroid/view/View$OnUnhandledKeyEventListener;

Resolved by adding configurations in Gradle files as below

configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == "androidx.appcompat") {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion "1.+"
            }
        }
    }
}

I struggled with same exception but only when testing my application on a real device (Samsung Galaxy S9). Same application was running fine on virtual devices. Since build.gradle config change did not solved, I worked around the problem by moving my main activity from AppCompatActivity to Activity. I sounds like downgrading your activity, but if you are not using advanced activity features - See this (https://developer.android.com/reference/androidx/appcompat/app/AppCompatActivity) - it's not a real problem.

//import androidx.appcompat.app.AppCompatActivity;
import android.app.Activity;

public class MainActivity /*extends AppCompatActivity*/ extends Activity

if you are using android x try this (add this code segment to app level Gradle file)

configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
    def requested = details.requested
    if (requested.group == "androidx") {
        if (!requested.name.startsWith("multidex")) {
            details.useVersion "${targetSdk}.+"
        }
    }
}}

if you are not using android x try this code segment.

configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
    def requested = details.requested
    if (requested.group == "com.android.support") {
        if (!requested.name.startsWith("multidex")) {
            details.useVersion "26.+"
        }
    }
}}

My problem was missing the androidx import in the build.gradle for one of the view elements in the layout that was being inflated. Adding implementation 'androidx.drawerlayout:drawerlayout:1.0.0 ' fixed my specific problem. I imagine there is some androidx view that is inside your Main Activity's layout that is not imported. All of the different packages and versions are at https://maven.google.com/web/index.html, simply find the item you are missing and add it to the dependencies in your module's build.gradle.

This error can be a decoy. In my case, the actual error turned out to be a Resources$NotFoundException somewhere in the stacktrace. When I replaced an <androidx.appcompat.widget.AppCompatImageView with ImageView I got a readable error which then was easy to solve.

I solved a similar issue by pasting this at the bottom of my build.gradle file

configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == "com.android.support") {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion "26.+"
            }
        }
    }
}

Sometimes after an upgrade, you need to invalidate and clear cache.

enter image description here

There are some known issues in 3.2 so also ensure you are not on Kotlin tools org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.70

as that causes freeze issues as well. If that doesn't work, remove your google plugin lines and support libraries, sync and add them again and sync. Sometimes the cache directories just get out of whack.
