ClassNotFoundException: Ich habe die Klasse "android.support.constraint.ConstraintLayout" im Pfad

Question

nicht gefunden. Ich arbeitete mit einigen Bibliotheken, daher musste ich Gradle-Einstellungen bearbeiten. Da meine App nicht funktionierte, habe ich sie im Android-Studio mit lokalem Verlauf wiederhergestellt, funktioniert aber immer noch nicht. Fehler zurückgegeben werden hier berichtet

Answer 1

Änderungen, die Sie zuvor vorgenommen haben, sind beschädigt Ihre Gradle-Datei (die Modul-Datei). Es sollte wie folgt aussehen:

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' 
} 

In Abhängigkeit für Constraint-Layout. Siehe Code
