}

ANDROID manifest.xml

<activity android:name=".check2" >

I am doing this but doesn't show me the message written in my other activities

@Uttam Didn't you got super not called exception?

I suppose you must call super.onCreate() in your check2.Not calling this in your check2 is causing Force Close

public class check2 extends Activity {
    public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);   //first call super.onCreate()
       Toast.makeText(
                this,
                "Welcome to second page", Toast.LENGTH_LONG).show();
        finish();  

    }

I suppose you still need to add:

@Override     
public void onPause(){
    super.onPause();
}

to both first and second activities.

Please change your first activity code as below

public class Check extends Activity implements OnClickListener {
    //private check2 check2;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button usemirror = (Button)findViewById(R.id.widget28);
        usemirror.setOnClickListener(this);

    }
    public void onClick(View view){


        Intent mi = new Intent(Check.this , check2.class);
        startActivity(mi);
}
}

& second activity code as below

public class check2 extends Activity {
    public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);   //first call super.onCreate()
       Toast.makeText(
                this,
                "Welcome to second page", Toast.LENGTH_LONG).show();
        finish();  

    }
