android.app.Application cannot be cast to com.example..AnalyticsApplication

I am new to android and in a process of adding google analytics to one of my application.
I am getting the following error when running my application.

android.app.Application cannot be cast to com.xxx.xxx.xxx.AnalyticsApplication


This is my main activity.

package com.example.dell.testanalytics;

import android.content.Intent;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;

import android.app.Application;

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


public class MainActivity extends AppCompatActivity {
private static final String TAG = "MainActivity";
private Tracker mTracker;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);


AnalyticsApplication application = (AnalyticsApplication) getApplication();
mTracker = application.getDefaultTracker();


}

@Override
public boolean onCreateOptionsMenu(Menu menu) {

getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {

// [START screen_view_hit]
String name = getString(R.string.test);
Log.i(TAG, "Setting screen name: " + name);
mTracker.setScreenName("Image~" + name);
mTracker.send(new HitBuilders.ScreenViewBuilder().build());
// [END screen_view_hit]
return false;
}


}


The error is pointing the place I call the analytics application method.

This is my manifest file

<?xml version="1.0" encoding="utf-8"?>




<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>


</application>




I cannot figure out what is wrong since i am not getting any errors or red lines in the code.

Would be great if i could get your assistance.

Answer

If you wish to replace the singleton Application instance with some subclass of Application, you need to have the android:name attribute of the <application> element of your manifest point to that subclass.
