当提升到目标SdkVersion 28，没有找到类"com.google.android.gms.common.R$string"路径： DexPathList

Question

当我尝试将我的targetSdkVersion从27更新到28时，我得到错误：

这是我构建的依赖项部分。格拉德尔：

dependencies {
    def lifecycle_version = "1.1.1"
//    def multidex_version = "2.0.1"
//    implementation 'androidx.multidex:multidex:2.0.1'
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.recyclerview:recyclerview:1.0.0'
    implementation 'androidx.annotation:annotation:1.0.2'
    androidTestImplementation('androidx.test.espresso:espresso-core:3.1.0', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'com.google.android.material:material:1.0.0'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
    implementation 'androidx.vectordrawable:vectordrawable:1.0.1'
    testImplementation 'junit:junit:4.12'
    implementation('androidx.constraintlayout:constraintlayout:1.1.3')
    implementation 'androidx.recyclerview:recyclerview:1.0.0'

    implementation 'com.google.firebase:firebase-ml-vision-image-label-model:17.0.2'
    implementation 'com.google.firebase:firebase-ml-model-interpreter:16.2.4'
    implementation 'com.drewnoakes:metadata-extractor:2.11.0'
    // AWS Mobile Client
    implementation('com.amazonaws:aws-android-sdk-mobile-client:2.6.+@aar') { transitive = true }
    // AWS Core
    implementation('com.amazonaws:aws-android-sdk-core:2.3.+')
    // AWS S3
    implementation('com.amazonaws:aws-android-sdk-s3:2.3.+')
    // AWS Cognito
    implementation('com.amazonaws:aws-android-sdk-cognitoidentityprovider:2.3.+')
    implementation 'com.amazonaws:aws-android-sdk-cognitoauth:2.4.7@aar'
    //AWS Lambda
    implementation('com.amazonaws:aws-android-sdk-lambda:2.2.+')

    implementation project(':plugin')
}

我已经尝试更新Firebase依赖关系到最新版本（这需要更新minSdkVersion从15到16），这没有效果（我不确定这是否是一个可行的选择，因为我似乎记得我的同事说一些关于条形码扫描不被支持，如果我把这些版本太高）。更新所有依赖项都没有错误地导致应用程序崩溃，我还没有弄清楚哪些是罪魁祸首；我决定尽可能多地关注这个问题，而不是无缘无故地招致更多麻烦。我已经尝试了几种不同的方法来启用Multidex，正如我在某个地方看到的那样；它们似乎都没有帮助。还有一些其他的东西我也尝试过，并且丢失了页面，但是我尝试过的都没有帮助。

如果您能帮助我解决此错误，我将不胜感激，因为在升级到28之前，我无法在Play Store中更新应用程序。

Answer 1

正如在该问题下的评论中所提到的，该问题最终导致Gradle超过3.6。0，不引发targetSdkVersion。但格雷德尔有什么问题？

这个答案让我更新了我的Firebase和ObjectBox版本，我认为这是以前做过的，但显然不是。但这导致了androidx类型的问题。appcompat。资源。R$attr被多次定义，它拒绝清理、重建和使缓存无效。这一点最终被删除。gradle文件夹以及清理和重建。

但是还有一个问题：Invoke-海关只支持从android O开始。我仍然不知道那是什么意思，但是设置

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

以我的身材。正如这里所说，格雷德尔似乎已经让我克服了这一点。
