I have finished a tip calculator app, but when i run it the name is `MainActivity`, i don't know how to change it, i have tried editing `strings.xml` but when i run the app i get errors, i don't know what else to try, any suggestions for what i can do to change it so it appears on the emulator


on strings.xml...

name:`title_activity_main`
value:`MainActivity`

    package tip.calculator;
    
    
    import android.os.Bundle;
    import android.app.Activity;
    import android.view.View.OnClickListener;
    import android.widget.EditText;
    import android.widget.TextView;
    import android.view.View;
    import android.widget.Button;
    import java.text.DecimalFormat;
    
    public class TipCalculator extends Activity 
    {
    private EditText myEditField;
    private EditText myEditField2;
    private Button enter;
    
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    
        myEditField2 = (EditText) findViewById(R.id.billText);
        myEditField = (EditText) findViewById(R.id.percentText);
        enter = (Button)findViewById(R.id.button1);
    
        enter.setOnClickListener(new OnClickListener() {
    
            public void onClick(View v) {
                TextView textView;
    
                textView = (TextView) findViewById(R.id.textView1);
    
                final EditText myEditField = (EditText) findViewById(R.id.percentText);
                final EditText myEditField2 = (EditText) findViewById(R.id.billText);
    
                float percentage;
                float percentageInp;
                float billAmount;
                double output; 
                String output1;
    
                percentageInp = Float.parseFloat(myEditField.getText().toString());
                billAmount = Float.parseFloat(myEditField2.getText().toString());
                
                percentage = ((float)percentageInp /100);
    
                output = (double)(billAmount * percentage);
               
                double result = output * 100;
                result = Math.round(result);
                result = result / 100;
    
                output1 = Double.toString(result);
    
                textView.setText(output1);
    
            }
        });
    }
    }
