AND SECOND ONE:

        public class Stat extends Activity{

            Button btstat;

            @Override
            protected void onCreate(Bundle savedInstanceState) {
                // TODO Auto-generated method stub
                super.onCreate(savedInstanceState);
                 setContentView(R.layout.rtlayout);

                 btstat = (Button) findViewById(R.id.button1);

                    btstat.setOnClickListener(new View.OnClickListener() 
                    {

                        public void onClick(View v) 
                        {
                            // TODO Auto-generated method stub

                            Intent intent = new Intent(Stat.this,Recieve.class);                    
                        startActivity(intent);
                    }
                }); 
        }   
    }

Answer 1

register your Recieve BroadcastReciver and Stat.java Activity in manifest as:

<receiver android:name=".Recieve" android:exported="true" > 
<intent-filter android:priority="999"> 
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter> 
</receiver>

<activity
    android:name=".Stat" />
 <activity
android:name=".SMSresponderActivity" />

uses-permission in your manifest file:

<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>

EDIT :finally big error is that Recieve is not an activity it's broadcast receiver or you are starting it as Activity so Change it bez when any new sms is reciver your Recieve automatic fire up

public void onClick(View v) 
                {
                  // TODO Auto-generated method stub

                  //Intent intent = new Intent(Stat.this,Recieve.class);
           Intent intent = new Intent(Stat.this,YOUR_NEXT_ACTIVITY.class); //you are passing Recieve here    
                        startActivity(intent);
                    }

Answer 2

Caused by: java.lang.ClassNotFoundException: com.project.SMSresponderActivity 

You are missing com.project.SMSresponderActivityon the manifest.

<activity
    android:name=".SMSresponderActivity"
    android:label="@string/smsResponder_name" >
</activity>

You'll need to specify all activities in your manifest, as well as receivers. I'm seeing that you don't have them either (as stated by @imran khan).
