GoogleAnalytics android getActivity（）。getApplication（）无法转换为AnalyticsApplication

Question

这是我得到错误的代码

@Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        // Obtain the shared Tracker instance.
        AnalyticsApplication application = (AnalyticsApplication) getActivity().getApplication();
        mTracker = application.getDefaultTracker();
}

这是我的AnalyticsApplication类

    synchronized public Tracker getDefaultTracker() {
        if (mTracker == null) {
            GoogleAnalytics analytics = GoogleAnalytics.getInstance(this);
            // To enable debug logging use: adb shell setprop log.tag.GAv4 DEBUG
            mTracker = analytics.newTracker(R.xml.global_tracker);
        }
        return mTracker;
    }
}

您的AndroidManifest。xml文件不包含自定义的应用程序子类，因此Android使用默认的子类（Android.app.Application）。
