我尝试通过适用于Android的Google跟踪代码管理器设置通用分析代码。我有一个空白活动（布局中没有任何内容）如下：
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_verification);
// Start GTM code
try
{
TagManager tagManager = TagManager.getInstance(this);
tagManager.setVerboseLoggingEnabled(true);
PendingResult<ContainerHolder> pending = tagManager.loadContainerPreferNonDefault("GTM-XXXXXX", R.raw.default_gtm_container);
pending.setResultCallback(new ResultCallback<ContainerHolder>()
{
@Override
public void onResult(ContainerHolder containerHolder)
{
ContainerHolderSingleton.setContainerHolder(containerHolder);
if (!containerHolder.getStatus().isSuccess())
{
Log.e("GoogleTagManager", "failure loading container");
return;
}
ContainerHolderSingleton.setContainerHolder(containerHolder);
containerHolder.setContainerAvailableListener(new ContainerHolder.ContainerAvailableListener()
{
@Override
public void onContainerAvailable(ContainerHolder containerHolder, String containerVersion)
{
containerHolder.getContainer();
}
});
}
}, 2, TimeUnit.SECONDS);
} catch (Exception e)
{
e.printStackTrace();
}
// End GTM code
}
@Override
public void onStart()
{
super.onStart();
DataLayer dataLayer = TagManager.getInstance(this).getDataLayer();
dataLayer.pushEvent("openScreen", DataLayer.mapOf("screenName", "Verification"));
}
我尝试做的只是在此活动开始时触发Universal Analytics代码。正如您在日志输出中看到的那样：

虽然引发了NullPointerException，但实际上已发送Google Analytics点击，我看到了实时报告中的点击。 NullPointerException导致我的应用程序崩溃，即使在应用程序崩溃后也会发送Google Analytics匹配。
为什么NullPointerException被抛出？它似乎被Google跟踪管理器课程抛出，但我不知道我做错了什么。我跟着CuteAnimalV4示例项目一直到最后一个字母。
请注意，我已隐藏Google跟踪代码管理器容器ID和Google Analytics帐户ID。这些是现实生活中的有效价值。

将在下一个Google Play服务版本中修复。现在，您可以添加未捕获的异常处理程序作为解决方法。
