android - 由 java.lang.NoClassDefFoundError 引起的 react native 致命异常

Question

我仅在我的新测试手机 (Android 6.0) 上遇到此致命异常。 这是错误日志:

E/AndroidRuntime: FATAL EXCEPTION: AsyncTask #2

此外，这是我的 app/build.gradle 文件:

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.1"

    defaultConfig {
        applicationId "com.***"
        minSdkVersion 16
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
        ndk {
            abiFilters "armeabi-v7a", "x86"
        }
    }

    signingConfigs {
        release {
            if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {
                storeFile file(MYAPP_RELEASE_STORE_FILE)
                storePassword MYAPP_RELEASE_STORE_PASSWORD
                keyAlias MYAPP_RELEASE_KEY_ALIAS
                keyPassword MYAPP_RELEASE_KEY_PASSWORD
            }
        }
    }

    splits {
        abi {
            reset()
            enable enableSeparateBuildPerCPUArchitecture
            universalApk false  // If true, also generate a universal APK
            include "armeabi-v7a", "x86"
        }
    }
    buildTypes {
        release {
            minifyEnabled enableProguardInReleaseBuilds
            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
            signingConfig signingConfigs.release
        }
    }
    // applicationVariants are e.g. debug, release
    applicationVariants.all { variant ->
        variant.outputs.each { output ->
            // For each separate APK per architecture, set a unique version code as described here:
            // http://tools.android.com/tech-docs/new-build-system/user-guide/apk-splits
            def versionCodes = ["armeabi-v7a":1, "x86":2]
            def abi = output.getFilter(OutputFile.ABI)
            if (abi != null) {  // null for the universal-debug, universal-release variants
                output.versionCodeOverride =
                        versionCodes.get(abi) * 1048576 + defaultConfig.versionCode
            }
        }
    }
}

dependencies {
    compile project(':react-native-fetch-blob')
    compile project(':react-native-image-picker')
    compile project(':react-native-background-upload')
    compile project(':react-native-fs')
    compile project(':react-native-video')
    compile project(':react-native-vector-icons')
    compile project(':react-native-linear-gradient')
    compile project(':react-native-camera')
    compile fileTree(dir: "libs", include: ["*.jar"])
    compile "com.android.support:appcompat-v7:24.0.1"
    compile "com.facebook.react:react-native:+"  // From node_modules
}

// Run this once to be able to run the application with BUCK
// puts all compile dependencies into folder libs for BUCK to use
task copyDownloadableDepsToLibs(type: Copy) {
    from configurations.compile
    into 'libs'
}

这是 Android 独有的问题，该应用程序在 iOS 上运行良好。此外，这似乎是一个仅限开发的问题。发布的APK没有这个问题。 有人面临或遇到过类似的问题吗？

谢谢

我得到了同样的结果，并发现这是因为我将 com.squareup.okhttp3.okhttp 解析为不是最新版本。

将其解析为 3.6.0 解决了我的问题
