Try this...

    Bundle extras = intent.getExtras();
    if(extras != null)
    String data = extras.getString("messages");

Replace.. Intent intent=getIntent(); String message=intent.getStringExtra("messages"); – Sachin Soma Jul 07 '18 at 08:00

Check your manifest.XML if the activity is registered.
The context try to use mainactivity.this

Hope it helps
