ViroCore：java.lang.NoClassDefFoundError错误：无法解析com/google/vr/ndk/base/GvrLayout的L形式；

Question

我已经下载了ViroCore库的最新版本(virocore-release-v_1_7_2.aar)，然后我将以下依赖项添加到我的build.gradle文件中。

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.+'}

然后我在下面编写了我的ViroActivity代码：

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() {
        }
    });

但是当运行该应用时，我总是看到以下异常：

E/AndroidRuntime: FATAL EXCEPTION: main
              Process: com.example.virosample.gvr.ovr, PID: 17304
              java.lang.NoClassDefFoundError: Failed resolution of: Lcom/google/vr/ndk/base/GvrLayout;
                  at com.viro.core.ViroViewGVR.init(ViroViewGVR.java:287)
                  at com.viro.core.ViroViewGVR.<init>(ViroViewGVR.java:211)
                  at com.example.panorama.ui.view.ViroActivityVR.createGVRView(ViroActivityVR.java:104)
                  at com.example.panorama.ui.view.ViroActivityVR.onCreate(ViroActivityVR.java:90)
                  ...

有人知道如何解决这个异常吗？

我解决了这个问题。我只添加了viro库到我的依赖项中，但是我必须额外添加sdk-common.aar和core.aar，你可以在官方的virocore网站上下载这些库。
