Application crash at runtime

Question

This will be my second question along these lines as the previous post seems to have pretty much stopped drawing attention, so sorry for the spam. Anyways, last time I posted because I was getting a runtime crash as well as various errors within my code, and someone managed to help me beyond the errors in the code. However, after fixing the code I'm still getting crashes. Included is the code I have for my project and the log cat file at the bottom.

A quick overview of what its supposed to do: I'm trying to make a few edit text fields add up into a TextView field so that users can type in numbers in the edit text columns and see the result in the textview.

package com.example.gideon.timemanagement;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.Editable;
import android.widget.EditText;
import android.text.TextWatcher;
import android.widget.TextView;



public abstract class Customize extends AppCompatActivity implements TextWatcher {


EditText a;
EditText b;
TextView ht;


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

    EditText a = (EditText) findViewById(R.id.exerciseHours);
    EditText b = (EditText) findViewById(R.id.sleepHours);
    TextView ht = (TextView) findViewById(R.id.healthTotal);
}

private TextWatcher Ht = new TextWatcher() {

    @Override
    public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

    }

    @Override
    public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {

    }

    @Override
    public void afterTextChanged(Editable editable) {


        if (!a.getText().toString().equals("") && !b.getText().toString().equals("")) {
            ht.setText(String.valueOf(Integer.valueOf(a.getText().toString()) + Integer.valueOf(b.getText().toString())));

        }
    }
};

Why is your Activity abstract class? And that logcat isn't the actual error — OneCricketeer, Feb 12 '18 at 06:02
so many reason for crash, first view declaration in both local and global are same, textwatcher method name are same. — Hemant Parmar, Feb 12 '18 at 06:04
If I don't make the class abstract it throws an error when trying to build. Error:(12, 8) error: Customize is not abstract and does not override abstract method afterTextChanged(Editable) in TextWatcher Also, how do I even get the full log cat? I have no idea. — GidKort, Feb 12 '18 at 07:03

Inside oncreate, remove EditText and Textview definitions because already you declare them as member variables in the class

add TextChangedListener on your editText

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

 a = (EditText) findViewById(R.id.exerciseHours);
 b = (EditText) findViewById(R.id.sleepHours);
 ht = (TextView) findViewById(R.id.healthTotal);
 a.addTextChangedListener(this);
 b.addTextChangedListener(this);
 }

Also remove abstract from class definition

Removing Abstract from the class causes an error. Error:(12, 8) error: Customize is not abstract and does not override abstract method afterTextChanged(Editable) in TextWatcher – GidKort Feb 12 '18 at 07:06
