Question

最近，我将Android项目从targetSdkVersion 26更改为28。我从Google Play收到了崩溃报告，出现“ java.lang.ClassNotFoundException ”错误

     java.lang.NoClassDefFoundError:

我不知道发生了什么。任何帮助将不胜感激

在gradle.build中，添加了multiDexEnabled

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    buildToolsVersion "28.0.0"   
    useLibrary 'org.apache.http.legacy'

    defaultConfig {
        applicationId "com.myapptool"

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
        }
    buildTypes {
        release {
            minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:28.0.0'
    compile 'com.android.support:recyclerview-v7:28.0.0'     
    compile 'com.android.support:design:28.0.0'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
    compile files('libs/achartengine-1.2.0.jar')
    compile project(':filemanager')
    compile project(':moreapp')
    compile files('libs/log4j-1.2.15.jar')
    compile 'de.hdodenhof:circleimageview:2.1.0'

    compile 'com.android.support:multidex:1.0.1'

}

这似乎是与multidex相关的问题。请在gradle.build

中启用multidex

 defaultConfig {
 // Enabling multidex support.
 multiDexEnabled true
}

dependencies {
implementation 'com.android.support:multidex:1.0.0'
}

将targetSdkVersion更改为28后获得java.lang.ClassNotFoundException错误
