2- Hardcoding Issues - Part 1

Vale, aquí el problema principal es que el secreto está hardcodeado (en texto plano) -> vendorsecretkey

package jakhar.aseem.diva;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.Toast;

public class HardcodeActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_hardcode);
    }

    public void access(View view) {
        EditText hckey = (EditText) findViewById(R.id.hcKey);

        if (hckey.getText().toString().equals("vendorsecretkey")) {
            Toast.makeText(this, "Access granted! See you on the other side :)", Toast.LENGTH_SHORT).show();
        }
        else {
            Toast.makeText(this, "Access denied! See you in hell :D", Toast.LENGTH_SHORT).show();
        }
    }
}
