java.lang.NoClassDefFoundError：com.amazonaws.mobileconnectors.apigateway.ApiResponse

Question

我对我的 Android 应用程序做了一些更改，现在我得到了这个。我认为这可能是由于更新我在应用程序中使用的自动生成的 ApiGateway SDK 引起的。但也许是别的什么？我什至不知道从哪里开始调试。

build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion '24.0.2'
    defaultConfig {
        applicationId "com.johndoe.supercoolsoftware"
        minSdkVersion 21
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    productFlavors {
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    //    compile fileTree(include: ['*.jar'], dir: 'app/libs')
    testCompile 'junit:junit:4.12'
    compile 'com.google.android.gms:play-services:9.2.0'
    compile 'com.google.android.gms:play-services-auth:9.2.0'
    compile 'com.facebook.android:facebook-android-sdk:4.14.1'
    compile 'com.android.support:appcompat-v7:23.0.0'
    compile 'com.android.support:design:23.0.0'
    compile 'com.amazonaws:aws-android-sdk-core:2.2.22'
    compile 'com.amazonaws:aws-android-sdk-s3:2.2.22'
    compile 'com.amazonaws:aws-android-sdk-cognitoidentityprovider:2.2.22'
    compile 'com.amazonaws:aws-android-sdk-cognito:2.2.22'
    compile 'com.amazonaws:aws-android-sdk-apigateway-core:2.2.22'
    compile 'com.google.code.gson:gson:2.2.4'
    //used for API Gateway SDK generated classes
    compile files('libs/Api-alpha-0.51.jar') #<- autogenerated SDK
}

apply plugin: 'com.google.gms.google-services'

好吧，我想通了。AWS 刚刚更新了他们的 Android 核心。所以现在当你构建它时使用的是较新的版本（现在是 v2.3.2），而旧版本是 v2.22.2。一旦我通过更改我的 Gradel 文件更新了我的 Android 应用程序以使用 v2.3.2，一切就正常了。

compile 'com.amazonaws:aws-android-sdk-core:2.3.2'
compile 'com.amazonaws:aws-android-sdk-s3:2.3.2'
compile 'com.amazonaws:aws-android-sdk-cognitoidentityprovider:2.3.2'
compile 'com.amazonaws:aws-android-sdk-cognito:2.3.2'
compile 'com.amazonaws:aws-android-sdk-apigateway-core:2.3.2'
