Android 应用程序和谷歌分析

Question

I have an android application that it worked with android webview and I thought to add google analytics to it.

I followed the official instructions from here . The application continues working properly but I don't take any response in google analytics website.

Below I show to you my code to see if I made some mistakes.

*In MainActivity you can see only the parts of code that I changes for google analytics.

Imports for Google Analytics

import com.google.android.gms.analytics.GoogleAnalytics;
import com.google.android.gms.analytics.HitBuilders;
import com.google.android.gms.analytics.Tracker;

MainActivity.java

    private WebView myWebView;
    private Tracker mTracker;
    private String name = new String("MyApp Main Screen");


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.activity_main);
        setVolumeControlStream(AudioManager.STREAM_MUSIC);
        myWebView = (WebView) this.findViewById(R.id.webView1);
        WebSettings settings = myWebView.getSettings();
        settings.setJavaScriptEnabled(true);
        myWebView.loadUrl("file:///android_asset/www/index.html");
        myWebView.setVerticalScrollBarEnabled(false);
        myWebView.setHorizontalScrollBarEnabled(false);
        settings.setDomStorageEnabled(true);
        settings.setDatabaseEnabled(true);
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
            settings.setDatabasePath("/data/data/" + myWebView.getContext().getPackageName() + "/databases/");
        }
        myWebView.addJavascriptInterface(new AudioInterface(this), "AndAud");
        myWebView.addJavascriptInterface(new InternetInteface(this), "AndInChk");
        myWebView.setWebChromeClient(new WebChromeClient() {
            @Override
            public void onExceededDatabaseQuota(String url,
                                                String databaseIdentifier,
                                                long currentQuota,
                                                long estimatedSize,
                                                long totalUsedQuota,
                                                WebStorage.QuotaUpdater quotaUpdater) {
                quotaUpdater.updateQuota(estimatedSize * 2);
            }
        });


        getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);


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


    }




    @Override
    protected void onResume() {
/* myWebView.onResume(); */
        myWebView.resumeTimers();
        super.onResume();


        mTracker.setScreenName(name);
        mTracker.send(new HitBuilders.ScreenViewBuilder().build());


    }

In previous code the parts for analytics are the following

private Tracker mTracker;
private String name = new String("MyApp Main Screen");

//in onCreate class
// Obtain the shared Tracker instance.
AnalyticsApplication application = (AnalyticsApplication) getApplication();
mTracker = application.getDefaultTracker();



//in onResume class
mTracker.setScreenName(name);
mTracker.send(new HitBuilders.ScreenViewBuilder().build());

AnalyticsApplication.java

package com.r.movie.quiz;

import android.app.Application;

import com.google.android.gms.analytics.GoogleAnalytics;
import com.google.android.gms.analytics.Tracker;


public class AnalyticsApplication extends Application {

    private Tracker mTracker;

    synchronized public Tracker getDefaultTracker() {
       if (mTracker == null) {
          GoogleAnalytics analytics = GoogleAnalytics.getInstance(this);

          mTracker = analytics.newTracker(R.xml.global_tracker);
       }
            return mTracker;
    }

}

build.gradle -> App level

apply plugin: 'com.android.application'


android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

Answer 1

Using EasyTracker is an alternative. EasyTracker is just an alternative to Tracker. If Tracker doesn't work you could try EasyTracker.

Example:

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.os.PowerManager;
import android.os.PowerManager.WakeLock;


import com.google.analytics.tracking.android.EasyTracker;
import com.google.analytics.tracking.android.MapBuilder;

public class Example extends Activity {

    @Override
    protected void onCreate(Bundle sis){
        super.onCreate(sis);

        et = EasyTracker.getInstance(Contact.this);
        et.send(MapBuilder.createEvent(TrackEventNameHandler.CLASS_CONTACT, TrackEventNameHandler.TRACK_EVENT_OK, TrackEventNameHandler.EVENT_TRACK, null).build());


    }

    EasyTracker et;
    @Override
    public void onStart(){
        super.onStart();
        EasyTracker.getInstance(this).activityStart(this);
    }
    @Override
    public void onStop() {
        super.onStop();
        EasyTracker.getInstance(this).activityStop(this);
    }

}

Answer 2

It works!

I recreate the account for application, and i use new json file with new USER-ID.

Also I delete the following lines of MainActivity code

//in onResume class
mTracker.setScreenName(name);
mTracker.send(new HitBuilders.ScreenViewBuilder().build());

and Ι create a function about that and I call it sendScreenName()

private void sendScreenName() {
    String name = "MainActivity";

    // [START screen_view_hit]
    mTracker.setScreenName(name);
    mTracker.send(new HitBuilders.ScreenViewBuilder().build());
    // [END screen_view_hit]
}

For the end, I added the following line in the end of onCreate:

 sendScreenName();

After all, when I open my application i saw the magic "1" number on analytics.google.com reports (real time)!
