我也在使用 SGSIII mini 进行开发。以下代码对我很有效:
private class ConnectThread extends Thread {
private final BluetoothSocket mmSocket;
private final BluetoothDevice mmDevice;
public ConnectThread(BluetoothDevice device) {
mmDevice = device;
BluetoothSocket tmp = null;
// Get a BluetoothSocket for a connection with the
// given BluetoothDevice
try {
//tmp = device.createRfcommSocketToServiceRecord(MY_UUID);
tmp = device.createInsecureRfcommSocketToServiceRecord(MY_UUID);
} catch (IOException e) {
Log.e(LOG_TAG, "create() failed", e);
}
mmSocket = tmp;
Main.myBluetoothSocket = mmSocket;
Main.myBluetoothDevice = mmDevice;
}
@Override
public void run() {
Log.i(LOG_TAG, "BEGIN mConnectThread");
setName("ConnectThread");
// Always cancel discovery because it will slow down a connection
mAdapter.cancelDiscovery();
// Send a failure message back to the Activity
Message msg = mHandler.obtainMessage(MESSAGE_TOAST);
Log.e(LOG_TAG, "Attempting connection to " + mmSocket.getRemoteDevice().getName());
String ss = "Attempting connection to " + mmSocket.getRemoteDevice().getName();
Bundle bundle = new Bundle();
bundle.putString(TOAST, ss);
msg.setData(bundle);
mHandler.sendMessage(msg);
// Make a connection to the BluetoothSocket
try {
// This is a blocking call and will only return on a
// successful connection or an exception
mmSocket.connect();
} catch (IOException e) {
Log.e(LOG_TAG, "*+*+*+* Connection Failed");
connectionFailed();
// Close the socket
try {
mmSocket.close();
} catch (IOException e2) {
Log.e(LOG_TAG, "unable to close() socket during connection failure", e2);
}
// Start the service over to restart listening mode
BluetoothCommandService.this.start();
return;
}
// Reset the ConnectThread because we're done
synchronized (BluetoothCommandService.this) {
mConnectThread = null;
}
// Start the connected thread
connected(mmSocket, mmDevice);
}
public void cancel() {
try {
mmSocket.close();
} catch (IOException e) {
Log.e(LOG_TAG, "close() of connect socket failed", e);
}
}
}
