How to Load Class Androidcomponentsextension After Upgrading the Android Gradle Plugin 7.1

Unable to load class AndroidComponentsExtension after upgrading the Android Gradle Plugin 7.1

Updating Navigation Safe Args

These lines are the important ones to look at:

Caused by: java.lang.NoClassDefFoundError: com/android/build/api/extension/AndroidComponentsExtension
    at androidx.navigation.safeargs.gradle.SafeArgsPlugin.apply(SafeArgsPlugin.kt:73)
    at androidx.navigation.safeargs.gradle.SafeArgsPlugin.apply(SafeArgsPlugin.kt:42)

This indicates that the error is coming from the Navigation Safe Args plugin.

As per the Android Gradle Plugin 7.1.0 release notes:

AGP APIs that the Navigation Safe Args Gradle plugin depend on have been removed. AGP 7.1 does not work with Navigation Safe Args versions 2.4.0-rc1 or 2.4.0, but will work with versions 2.5.0-alpha01 and 2.4.1. In the meantime, as a workaround, you can use AGP 7.1 with a snapshot build of Navigation Safe Args, Navigation 2.5.0-SNAPSHOT. To use the snapshot build, follow the snapshot instructions with build id #8054565.

As Navigation 2.4.1 is now available, you can upgrade to that version of Navigation to gain the fix:

Backported from Navigation 2.5.0-alpha01: Safe Args now depends on Android Gradle Plugin version 7.0.4. This means that Navigation Safe Args will no longer be compatible with Android Studio versions prior to 7.0, but is now compatible with Android Gradle Plugin 7.1.0 and higher.

dependencies {
    classpath 'com.android.tools.build:gradle:7.1.0'

    // Update this line to use 2.4.1
    classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.4.1"
}

Note that you should always use the same version of the Navigation library as the Safe Args plugin (i.e., your app should also use Navigation 2.4.1): you should not try to use the Navigation 2.4.1+ Safe Args plugin with an earlier version of Navigation (such as 2.3.5).

Note on Firebase Perf Plugin

Note that you might see this same error when you are using:

classpath "com.google.firebase:perf-plugin:1.4.0"

With an idea.log of that states:

Caused by: java.lang.NoClassDefFoundError: com/android/build/api/extension/AndroidComponentsExtension
    at com.google.firebase.perf.plugin.FirebasePerfClassVisitorFactory.registerForProject(FirebasePerfClassVisitorFactory.java:54)
    at com.google.firebase.perf.plugin.FirebasePerfPlugin.perform(FirebasePerfPlugin.java:145)
    at com.google.firebase.perf.plugin.FirebasePerfPlugin.lambda$apply$0(FirebasePerfPlugin.java:107)

As per the Firebase Perf Plugin 1.4.1 Release Notes:

Migrated away from the deprecated Android Gradle plugin APIs.

So you should upgrade to 1.4.1:

classpath "com.google.firebase:perf-plugin:1.4.1"

How to add classpath in new version of Android Studio

In the latest version in February 2022 doesn't need to add buildscript anymore just add the id in build.gradle for project. It will be like this in build.gradle for project:

plugins {
    id 'com.android.application' version '7.1.2' apply false
    id 'com.android.library' version '7.1.2' apply false
    id 'org.jetbrains.kotlin.android' version '1.6.10' apply false

    id 'androidx.navigation.safeargs' version '2.4.1' apply false
    // classpath are changed, so no need to add classpath anymore just the id and the version
}

Don't forget add the id again in the build.gradle module,

plugins {
    id 'com.android.application'
    id 'org.jetbrains.kotlin.android'
    id 'androidx.navigation.safeargs'
}

New build.gradle in Android Studio Bumblebee | 2021.1.1 Beta 5 error adding dependencies

You can do this thing.

ext {
    compose_version = '1.0.5'
    kotlin_version = '1.6.10'
}
// Top-level build file where you can add configuration options common to all sub-projects/modules.
plugins {
    id 'com.android.application' version '7.1.0' apply false
    id 'com.android.library' version '7.1.0' apply false
    id 'org.jetbrains.kotlin.android' version "$kotlin_version" apply false
    id "com.google.dagger.hilt.android" version "2.41" apply false
    id 'androidx.navigation.safeargs.kotlin' version '2.5.0-alpha01' apply false // use this one
//    classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.4.0" (will not work now)

}

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

Android Gradle Plugin 7.2 ignores added proguard file in Android App build process

In Groovy the value can be set for android.defaultConfig:

// this sets one file
android.defaultConfig { config ->
    proguardFile new File("../general.pro")
}

// this adds an additional file
android.defaultConfig { config ->
    proguardFiles.add(new File("../general.pro"))
}

// proof of concept
android.buildTypes { buildType ->
    println buildType
}

This happens before :prepareKotlinBuildScriptModel, which means early on.
