java - google analytics v4 on android crashing -

i trying track app statistics using google analytics. trying follow tutorial @ http://java.dzone.com/articles/working-google-analytics-api several people have posted , said works them. here code :

my app_tracker.xml file below

<?xml version="1.0" encoding="utf-8"?> <resources xmlns:tools="http://schemas.android.com/tools" tools:ignore="typographydashes"> <span style="line-height: 1.5; font-style: inherit; font-weight: inherit;"> </span> <string name="ga_trackingid">ua-xxxxxxx-1</string> <string name="ga_samplefrequency">100.0</string> <bool name="ga_autoactivitytracking">true</bool> <bool name="ga_reportuncaughtexceptions">true</bool> <integer name="ga_sessiontimeout">-1</integer> <screenname name="game">game</screenname> <screenname name="settings">settings</screenname> </resources>

my global_tracker xml file below:

<?xml version="1.0" encoding="utf-8"?> <resources xmlns:tools="http://schemas.android.com/tools" tools:ignore="typographydashes"> <span style="line-height: 1.5; font-style: inherit; font-weight: inherit;"> </span> <string name="ga_loglevel">verbose</string> <integer name="ga_dispatchperiod">30</integer> <bool name="ga_dryrun">false</bool> <string name="games">games</string> <string name="settings">settings</string> </resources>

in manifest file have entered next code block:

<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

my main activity looks :

import com.google.android.gms.analytics.googleanalytics; import com.google.android.gms.analytics.tracker; public class mainactivity extends activity implements view.onclicklistener { @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); ((myapplication)getapplication()).gettracker(myapplication.trackername.app_tracker); }

the myapplication class app should have follows

public class myapplication extends application { private static final string property_id = "ua-xxxxxxxx-1"; private static final string tag = "myapp"; public static int general_tracker = 0; public enum trackername { app_tracker, // tracker used in app. global_tracker, // tracker used apps company. eg: roll-up tracking. ecommerce_tracker, // tracker used ecommerce transactions company. } hashmap<trackername, tracker> mtrackers = new hashmap<trackername, tracker>(); public myapplication() { 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(property_id) : analytics.newtracker(r.xml.ecommerce_tracker); mtrackers.put(trackerid, t); } homecoming mtrackers.get(trackerid); } }

when programme running, crashes when reaches line

((myapplication)getapplication()).gettracker(myapplication.trackername.app_tracker);

in main activity. have spent weeks trying find way around no success. can please help me configure google analytics v4 in android project?

you need add together application name in manifest file.

<application android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:name=".mainapplication" > </application>
