集成谷歌分析“v4"进入安卓应用 [英] Integrate Google Analytics "v4" into an Android app

问题描述

感谢您的回答，但还是不行.

Thanks for the answer, but it still does not work.

我已经创建了:

public class GAnalytics extends Application{

// The following line should be changed to include the correct property id.
private static final String PROPERTY_ID = "UA-XXXX-X";

public static int GENERAL_TRACKER = 0;

public enum TrackerName {
    APP_TRACKER, // Tracker used only in this app.
    GLOBAL_TRACKER, // Tracker used by all the apps from a company. eg: roll-up tracking.
    ECOMMERCE_TRACKER, // Tracker used by all ecommerce transactions from a company.
}

HashMap<TrackerName, Tracker> mTrackers = new HashMap<TrackerName, Tracker>();

public GAnalytics() {
    super();
}

synchronized Tracker getTracker(TrackerName trackerId) {
    if (!mTrackers.containsKey(trackerId)) {

        GoogleAnalytics analytics = GoogleAnalytics.getInstance(this);
        Tracker t = (trackerId == TrackerName.APP_TRACKER) ? analytics.newTracker(PROPERTY_ID)
                : (trackerId == TrackerName.GLOBAL_TRACKER) ? analytics.newTracker(
                        R.xml.global_tracker)
                        : analytics.newTracker(R.xml.ecommerce_tracker);
        mTrackers.put(trackerId, t);

    }
    return mTrackers.get(trackerId);
}

}

在我的 MainActivity 的 OnCreate 下:

Under OnCreate in my MainActivity:

String ACTIVITY_NAME = "MyApp";
// Get tracker.
    Tracker t = ((GAnalytics) getApplication()).getTracker(TrackerName.APP_TRACKER);

    // Set screen name.
    // Where path is a String representing the screen name.
    t.setScreenName(ACTIVITY_NAME);

    // Send a screen view.
    t.send(new HitBuilders.AppViewBuilder().build());

我在 Application (android: name...) 下添加了清单

I have added the manifest under Application (android: name...)

还有我的日志:

推荐答案

如您的链接中所述，GA 相关代码应放置在 Application 类中，而不是 Activity.

As described in your link, the GA-related code should be placed inside the Application class instead of the Activity.

像这样创建一个类扩展Application:

Create a class extends Application like this:

public class MyApplication extends Application{
    //the tracker related code should be place here (the enum, getTracker, mTrackers)
}

然后在您的 AndroidManifest.xml 中，在 application 标记下，将 android:name 替换为上面的 MyApplication类.

then in your AndroidManifest.xml, under the application tag, replace the android:name with the above MyApplication class.

tracker代码应该放在Activity.oncreate方法中比如

The tracker code should be placed in the Activity.oncreate method such as

public class MainActivity extends Activity {
.
.
.
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
// Get tracker.
    Tracker t = ((AnalyticsSampleApp) getApplication()).getTracker(
        TrackerName.APP_TRACKER);

    // Set screen name.
    // Where path is a String representing the screen name.
    t.setScreenName(path);

    // Send a screen view.
    t.send(new HitBuilders.AppViewBuilder().build());
}
.
.
.
}
