java.lang.NoClassDefFoundError: com.google.common.base.CharMatcher

Question

我正在尝试在 Lollipop 设备上运行我的应用程序，在 Lollipop 应用程序运行正常之后，但是，在 5.0 或更低版本的 Android 中，我的应用程序崩溃并返回此错误：

Process: com.myApp.agr1010, PID: 4353 java.lang.NoClassDefFoundError: com.google.common.base.CharMatcher

但是，我的 Build.Gradle 已经包含MultiDexEnable true

这是我的 Build.gradle：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.3"
    defaultConfig {
        applicationId "com.myApp.agr1010"
        minSdkVersion 21
        targetSdkVersion 29
        multiDexEnabled true
        versionCode 3
        versionName "0.8.9-Alpha Release"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'

        }
    }
    compileOptions {
        sourceCompatibility = 1.8
        targetCompatibility = 1.8
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation('com.google.guava:guava:29.0-jre')
    implementation 'androidx.constraintlayout:constraintlayout:2.0.1'

    implementation 'com.google.android.gms:play-services-location:17.0.0'

    // and a lot of implementation...
}
apply plugin: 'com.google.gms.google-services'
apply plugin: 'com.google.firebase.firebase-perf'
apply plugin: 'com.google.firebase.crashlytics'

还有我完整的 logCat：

我已经尝试将 MultiDex 添加到 Androidx 和 android 支持，但是，同样的问题再次发生，我该如何解决？

Answer 1

从您的 gradle 文件implementation('com.google.guava:guava:29.0-jre')添加implementation 'com.google.guava:guava:30.0-android'而不是这一行

仅添加 android 依赖项似乎有效。
