我的Android應用程序與服務器保持套接字連接，當設備連接到Wi-Fi時此連接正常工作，並且只有在設備連接到移動網絡時纔會失敗。錯誤跟蹤如下WebSocketClient在移動網絡上僅失敗

私有類，
private class PingPacket { protected byte id;
protected Timer timer;
protected PingPacket(byte id) {
this.id = id;
timer = new Timer();
}
protected void sendPing(WebSocketClient client) {
FramedataImpl1 frame = new FramedataImpl1(Opcode.PING);
frame.setFin(true);
client.sendFrame(frame);
Log.d("WebSocketService", id + " ping sent");
timer.schedule(new TimerTask() {

什麼可能會導致這？
