Android ViroCore:java.lang.NoClassDefFoundError:解析失败：Lcom/google/vr/ndk/base/GvrLayout；

我已经下载了ViroCore lib的最新版本（ViroCore-release-v_1_7_2.aar），然后在build.gradle文件中添加了以下依赖项

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:25.0.0'
implementation 'com.google.android.exoplayer:exoplayer:r2.2.0'
androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
testImplementation 'junit:junit:4.12'
implementation (name:'virocore-release-v_1_7_2', ext: 'aar')
implementation 'com.google.protobuf.nano:protobuf-javanano:3.0.0-alpha-7'
implementation 'com.amazonaws:aws-android-sdk-core:2.2.+'
implementation 'com.amazonaws:aws-android-sdk-ddb:2.2.+'
implementation 'com.amazonaws:aws-android-sdk-ddb-mapper:2.2.+'
implementation 'com.amazonaws:aws-android-sdk-cognito:2.2.+'
implementation 'com.amazonaws:aws-android-sdk-cognitoidentityprovider:2.2.+'}

然后写下我的病毒活性代码如下：

private ViroView createGVRView() {
    return new ViroViewGVR(this, new ViroViewGVR.StartupListener() {

        @Override
        public void onSuccess() {
            onRendererStart();
        }

        @Override
        public void onFailure(ViroViewGVR.StartupError error, String errorMessage) {
            onRendererFailed(error.toString(), errorMessage);
        }
    }, new Runnable() {
        @Override
        public void run() {
        }
    });

}

但在运行应用程序时，我总是会看到下一个异常：

E/AndroidRuntime: FATAL EXCEPTION: main
              Process: com.example.virosample.gvr.ovr, PID: 17304

有人知道如何解决这个异常吗？

我解决了这个问题。我在依赖项中添加了viro库，但我必须另外添加sdk-common.aar和core.aar，您可以在官方virocore站点下载它们
