android - Google Tag Manager Android - 不支持 JSONArrays

Question

我读过 this我正在使用适用于 Android v5 的 Google 跟踪代码管理器。

+--- com.google.android.gms:play-services-tagmanager:9.4.0
|    +--- com.google.android.gms:play-services-analytics-impl:9.4.0
|    |    +--- com.google.android.gms:play-services-base:9.4.0 (*)
|    |    \--- com.google.android.gms:play-services-basement:9.4.0 (*)
|    +--- com.google.android.gms:play-services-basement:9.4.0 (*)
|    \--- com.google.android.gms:play-services-tagmanager-api:9.4.0
|         +--- com.google.android.gms:play-services-basement:9.4.0 (*)
|         \--- com.google.firebase:firebase-analytics:9.4.0 (*)

容器是实时的，我下载了 JSON 文件。

我正在使用 this approach而不是将 JSON 文件放在 /assets/containers/ 中，因为我需要在运行时配置 Google Analytics 属性
(我有 2 个 GA 属性，一个生产和 1 个测试)

我的启动器 Activity :

public class SplashActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        Logger.d("onCreate");
        super.onCreate(savedInstanceState);

        initGTM();
    }
    private void initGTM() {
        TagManager tagManager = TagManager.getInstance(getApplicationContext());
        PendingResult pending = tagManager. loadContainerPreferNonDefault(
                "GTM_XXXABC",
                R.raw.gtm_xxxabc);
        ContainerHolder containerHolder = (ContainerHolder) pending.await(2, TimeUnit.SECONDS);
        String value = containerHolder.getContainer().getString("myKey");
        Logger.w("status is " + containerHolder.getStatus());

        DataLayer dataLayer = TagManager.getInstance(getApplicationContext()).getDataLayer();
        dataLayer.pushEvent("openScreen", DataLayer.mapOf("screenName", "Main Page"));
    }
}

完整的堆栈跟踪:

Google 跟踪代码管理器容器:

Answer 1

创建一个Legacy 容器解决了这个问题。我能够像这里提到的那样下载二进制文件。
