Added custom class for storing variables to main java folder and android manifest - still getting class cast exception!

The question above explains it. I asked about it earlier and made a few changes but have the same exact errors as before!

Here is my current activity code:

`` package ericleeconklin.costoflivingcalculator;

import android.content.Intent; import android.support.v7.app.ActionBarActivity; import android.os.Bundle; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.widget.TextView; import java.lang.Double;

public class EnterIncome extends ActionBarActivity {

public Double myIncome;

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


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_enter_income, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

public void getIncome(View view){
    String myIncomeString;
    TextView incomeView = (TextView)findViewById(R.id.enterIncome);
    myIncomeString = incomeView.getText().toString();
    myIncome = Double.parseDouble(myIncomeString);
    ((MyVariables) this.getApplication()).setIncome(myIncome);
    Intent myIntent = new Intent(this, EnterExpenses.class);
    startActivity(myIntent);
}

} ``

Here is my android manifest:

android:name="android.app.Application"

And finally, here is the custom class, MyVariables:

`` package ericleeconklin.costoflivingcalculator;

import android.app.Application;

/**

• Created by Eric on 8/12/2015. */ public class MyVariables extends Application { private Double income;

  public Double getIncome() { return income; }

  public void setIncome(Double income) { this.income = income; }

  private Double rentMortgage;

  public Double getrentMortgage() { return rentMortgage; }

  public void setrentMortgage(Double rentMortgage) { this.rentMortgage = rentMortgage; }

  private Double insurance;

  public Double getinsurance() { return insurance; }

  public void setinsurance(Double insurance) { this.insurance = insurance; }

  private Double utilities;

  public Double getutilities() { return utilities; }

  public void setutilities(Double utilities) { this.utilities = utilities; }

  private Double phoneInternet;

  public Double getphoneInternet() { return phoneInternet; }

  public void setphoneInternet(Double phoneInternet) { this.phoneInternet = phoneInternet; }

  private Double food;

  public Double getfood() { return food; }

  public void setfood(Double food) { this.food = food; }

  private Double carPayment;

  public Double getcarPayment() { return carPayment; }

  public void setcarPayment(Double carPayment) { this.carPayment = carPayment; }

  private Double misc;

  public Double getmisc() { return misc; }

  public void setmisc(Double misc) { this.misc = misc; } } ``
