ClassNotFoundException: n'a pas trouvé la classe "Android.support.constraint.ConstraintLayout" sur le chemin

Je travaillais avec certaines bibliothèques, j'ai donc dû modifier les paramètres Gradle. Étant donné que mon application ne fonctionnait pas, je l'ai restaurée avec l'historique local dans Android studio mais cela ne fonctionne toujours pas. Les erreurs renvoyées sont signalées ici

Stefano

Les modifications que vous avez apportées précédemment ont corrompu votre fichier Gradle (celui du module). Ça devrait ressembler à ça:

apply plugin: 'com.Android.application'

Android {

    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "***" /*Your package name*/
        minSdkVersion 15
        targetSdkVersion 25
        versionCode 5
        versionName "1.4"
        testInstrumentationRunner "Android.support.test.runner.AndroidJUnitRunner"
        vectorDrawables.useSupportLibrary = true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-Android.txt'), 'proguard-rules.pro'
        }
    }
}
repositories {
    jcenter()
    maven { url "https://jitpack.io" }
}

dependencies {
//Your Dependencies
//Don't forget to add dependency of constraint-layout
    compile 'com.Android.support.constraint:constraint-layout:1.0.2'
}

Ajoutez une dépendance pour la disposition des contraintes. Voir code

REMARQUE: la compilation est devenue obsolète et a été remplacée par le mot-clé "implémentation", alors remplacez "compiler" par "implémentation"

donc le code sera

dependencies {
//Your Dependencies
//Don't forget to add dependency of constraint-layout
    implementation 'com.Android.support.constraint:constraint-layout:1.1.0'
}

MISE À JOUR: Si vous avez mis à niveau vers AndroidX maintenant. Ensuite, vous devez utiliser androidx.constraintlayout.widget.ConstraintLayout au lieu d'Android.support.constraint.ConstraintLayout

Ishaan Kumar

Vous avez peut-être mis à jour la bibliothèque de support AndroidX et la mise en page fait référence à l'ancienne version de ConstraintLayout. Vous devez donc mettre à jour le Android.support.constraint.ConstraintLayout balises à androidx.constraintlayout.widget.ConstraintLayout dans votre mise en page XML.
