unfortunately,project has stopped in android studio

Question

The code is all about taking the zodiac sign as the input in the 1st activity and when clicked OK navigates to the next activity where it displays the details as the web view of that particular zodiac sign. When ever I try to run the code in the emulator or in my mobile I get a warning project is continuously stopping and the application closes.

MainActivity.java

  package com.example.project;

  import android.content.Intent;
  import android.os.Bundle;
  import android.text.Editable;
  import android.view.View;
  import android.webkit.WebView;
  import android.widget.EditText;

public class MainActivity extends AppCompatActivity {

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

}
public void send(View v){
    Intent goToSecond = new Intent();
    goToSecond.setClass(this, SecondActivity.class);
    startActivity(goToSecond);
    String sign = ((EditText)(findViewById(R.id.editText_sign))).getText().toString();
    goToSecond.putExtra("sign", sign);
    startActivity(goToSecond);
}
}

Did you follow the detailed instructions in the error log? – chrylis -cautiouslyoptimistic- Apr 22 '20 at 10:37 — chrylis -cautiouslyoptimistic-, Apr 22 '20 at 10:37
yes, I did but facing the same problem at second activity. – Pradyumna Shashank Apr 23 '20 at 08:01 — Pradyumna Shashank, Apr 23 '20 at 08:01

You are calling startActivity twice, also .setClass is not needed:

   public void send(View v){
     String sign = ((EditText)(findViewById(R.id.editText_sign))).getText().toString();
        Intent goToSecond = new Intent(this, SecondActivity.class);
        //startActivity(goToSecond);//Comment this line
        goToSecond.putExtra("sign", sign);
       startActivity(goToSecond);
}

In secondactivity you are doing findViewById before setContentView add the below line after setContentView in SecondActivity

webView = findViewById(R.id.webview);

Your Exception says there is a nullpointer exception so add a null check to your code:

String sign = "";
if (getIntent != null){
Intent caller = getIntent();
String sign = caller.getStringExtra("sign");
}

Hope this helps

@PradyumnaShashank are you seeing same error log? Can you update the error log? – keshav kowshik Apr 23 '20 at 07:15
@PradyumnaShashank your log in question details about ads but in your code you have not used add any where have you added that in gradle? – keshav kowshik Apr 23 '20 at 07:19

this is the log which is being seen after making the update you have mentioned. @Keshav1234 – Pradyumna Shashank Apr 23 '20 at 12:43
@PradyumnaShashank this does not specify anything, once the installation is finished you can see an error in logcat, you can filter the logcat to show only the exeception. If you add that log I can tell what might be the issue. – keshav kowshik Apr 23 '20 at 17:14
