Here is an example that might help
Server.java:

package com.example.bindservice.binder;  import java.text.SimpleDateFormat; import java.util.Date;  import android.app.Service; import android.content.Intent; import android.os.Binder; import android.os.IBinder;  public class Server extends Service {      IBinder mBinder = new LocalBinder();      @Override     public IBinder onBind(Intent intent) {         return mBinder;     }      public class LocalBinder extends Binder {         public Server getServerInstance() {             return Server.this;         }     }      public String getTime() {         SimpleDateFormat mDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");         return mDateFormat.format(new Date());     } } 

Client.java

package com.example.bindservice.binder;  import android.app.Activity; import android.content.ComponentName; import android.content.Intent; import android.content.ServiceConnection; import android.os.Bundle; import android.os.IBinder; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.TextView; import android.widget.Toast;  import com.example.bindservice.binder.Server.LocalBinder;  public class Client extends Activity {      boolean mBounded;     Server mServer;     TextView text;     Button button;      @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.main);          text = (TextView)findViewById(R.id.text);         button = (Button) findViewById(R.id.button);         button.setOnClickListener(new OnClickListener() {             public void onClick(View v) {                 text.setText(mServer.getTime());             }         });     }      @Override     protected void onStart() {         super.onStart();          Intent mIntent = new Intent(this, Server.class);         bindService(mIntent, mConnection, BIND_AUTO_CREATE);     };      ServiceConnection mConnection = new ServiceConnection() {         @Override         public void onServiceDisconnected(ComponentName name) {             Toast.makeText(Client.this, "Service is disconnected", 1000).show();             mBounded = false;             mServer = null;         }          @Override         public void onServiceConnected(ComponentName name, IBinder service) {             Toast.makeText(Client.this, "Service is connected", 1000).show();             mBounded = true;             LocalBinder mLocalBinder = (LocalBinder)service;             mServer = mLocalBinder.getServerInstance();         }     };      @Override     protected void onStop() {         super.onStop();         if(mBounded) {             unbindService(mConnection);             mBounded = false;         }     }; }
