我在我的Java項目中使用rxtx library來讀取來自我的gps芯片的串行數據。現在，我嘗試將其移植到我的Android設備，這是一款帶有Android 4.0.3股票ROM的根源Galaxy Nexus。Android上的RXTX串行端口庫
我已經創建了一個項目並將我的類移植到Android版本。它使用rxtx library for android這樣的：
public void init() {
try {
Enumeration portIdentifiers = CommPortIdentifier.getPortIdentifiers();
///See what ports are available. and latch on desired port
while (portIdentifiers.hasMoreElements()) {
CommPortIdentifier pid = (CommPortIdentifier) portIdentifiers.nextElement();
if (pid.getPortType() == CommPortIdentifier.PORT_SERIAL && pid.getName().equals(PORT)) {
portId = pid;
break;
}
}
serialPort = (SerialPort) portId.open("test", 5000);
in = serialPort.getInputStream();
dis = new DataInputStream(in);
serialPort.addEventListener(this);
serialPort.setSerialPortParams(BAUDRATE, SerialPort.DATABITS_8, SerialPort.STOPBITS_1,
SerialPort.PARITY_NONE);
serialPort.notifyOnDataAvailable(true);
} catch (PortInUseException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (TooManyListenersException e) {
e.printStackTrace();
} catch (UnsupportedCommOperationException e) {
e.printStackTrace();
}
}
在此之後我嘗試用serialEvent(SerialPortEvent event) - 方法來讀取輸入數據。
但是我不會讀取數據，因爲庫的本地實現存在一些問題。這是我的logcat輸出：

最後三行重複，直到我殺死我的手機上的過程。串口上沒有數據，實際上它似乎還沒有被初始化。對此有何建議？
我想在我的android項目中使用rxtx庫。你能幫我設置它嗎？ –
