I need to test my android program by sending strings to my PC with bluetooth communication.

I have found this app which exactly sends strings to an arduino

You can create a Java application to act as Bluetooth server and using it for testing with you Bluetooth client app.

You will need to Bluecove library for this, here is an example code snippet:

UUID serialUUID = new UUID("1101", true);
String SERVICE_URL = "btspp://localhost:" + serialUUID
        + ";name=My Bluetooth Server;authorize=false;authenticate=false";

StreamConnectionNotifier connectionNotifier = 
                          (StreamConnectionNotifier) Connector.open(SERVICE_URL);

System.out.println("Server is waiting for client ... \n URL=" + SERVICE_URL);

// Wait until client connects i.e. a blocking method
StreamConnection connection = connectionNotifier.acceptAndOpen();

RemoteDevice remoteDevice = RemoteDevice.getRemoteDevice(connection);
System.out.println("Client connected: "+remoteDevice.getBluetoothAddress());

// Communicate with the device using the below I/O streams
InputStream iStream = connection.openInputStream();
OutputStream oStream = connection.openOutputStream();
