The app is crashing

Where I went wrong?

What I have tried:

MainActivity

   package com.example.nikhilarora.loginform;
   import android.content.Intent;
   import android.support.v7.app.AppCompatActivity;
   import android.os.Bundle;
   import android.view.View;
   import android.widget.Button;
   import android.widget.EditText;
            
   public class MainActivity extends AppCompatActivity implements View.OnClickListener {
        
      EditText editText, editText2;
      Button b;
        
      @Override
      protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
         editText = (EditText) findViewById(R.id.editText);
         editText2 = (EditText) findViewById(R.id.editText2);
         b = findViewById(R.id.button);
         b.setOnClickListener(this);
      }
        
      @Override
      public void onClick(View v) {
         if (v.getId() == R.id.button) {
            if (editText.getText().toString().equals("admin") && editText.getText().toString().equals("admin")) {
               Intent i = new Intent(this, Main2Activity.class);
               startActivity(i);

"Where I went wrong?"

By not single-stepping through the code using the debugger, and not having any error checking or try/catch blocks.

"unfortunately, the app has stopped."
It means not only the error must be in your login process code.
It can be other also - So use try catch block and check it out.
