Google Analytics (V4) OnCreate Cannot cast from Application - analytics

Question

I have followed a better tutorial than the google one to start to get analytics in my app.
The problem is that
package com.sgdva.ishikawa;
import com.google.android.gms.analytics.Tracker;
import com.google.android.gms.analytics.GoogleAnalytics;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import java.util.HashMap;
public class Ishikawa extends Activity {
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.sources, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.action_settings:
startActivity(new Intent(Ishikawa.this, Sources.class));
return true;
default:
return super.onOptionsItemSelected(item);
}
}
// The following line should be changed to include the correct property id.
private static final String PROPERTY_ID = "UA-50596309-1";
// Logging TAG
private static final String TAG = "Ishikawa";
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 Ishikawa() {
super();
}
synchronized Tracker getTracker(TrackerName trackerId) {
if (!mTrackers.containsKey(trackerId)) {
GoogleAnalytics analytics = GoogleAnalytics.getInstance(this);
Tracker t = (trackerId == TrackerName.APP_TRACKER) ? analytics
.newTracker(R.xml.app_tracker)
: (trackerId == TrackerName.GLOBAL_TRACKER) ? analytics
.newTracker(PROPERTY_ID) : analytics
.newTracker(R.xml.ecommerce_tracker);
mTrackers.put(trackerId, t);
}
return mTrackers.get(trackerId);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get a Tracker (should auto-report)
((Ishikawa) getApplication())
.getTracker(Ishikawa.TrackerName.APP_TRACKER);
setContentView(R.layout.activity_ishikawa);
In this line
((Ishikawa) getApplication()).getTracker(Ishikawa.TrackerName.APP_TRACKER);
It says:Cannot cast from Application to Ishikawa
I have read that this is because my android name is not delcared in my manifest.xml but it is
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.sgdva.ishikawa"
android:versionCode="2"
android:versionName="1.1" >

android:targetSdkVersion="18" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.INTERNET"/>
<application
android:allowBackup="true"
android:name="com.sgdva.ishikawa.Ishikawa"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme"
>
<!-- Google Analytics Version v4 needs this value for easy tracking -->
<meta-data android:name="com.google.android.gms.analytics.globalConfigResource"
android:resource="#xml/global_tracker" />
<activity
android:name="com.sgdva.ishikawa.Ishikawa"
android:label="#string/app_name"
android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />

</activity>
<activity

</activity>
<activity android:name="com.google.android.gms.ads.AdActivity" android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|s mallestScreenSize"/>
<meta-data android:name="com.google.android.gms.version"

<activity
android:name="com.sgdva.ishikawa.MainActivity"
android:label="#string/title_activity_main"
android:screenOrientation="portrait">
</activity>
</application>
</manifest>
Why would this happen?

Answer 1

It was my bad, I was calling my "activity" as an "application"
((Ishikawa) getApplication()).getTracker(Ishikawa.TrackerName.APP_TRACKER);
I made another .class called "Tracker.java" get the code for analytics there and referenced it instead:
((Tracker) getApplication()).getTracker(Tracker.TrackerName.APP_TRACKER);
