联网等类会lock线程的操作必须新开线程

blackbarry jdk 明确提示,Connector.open方法会lock当前线程,这样就会导致正在运行程序像死机样,所以,必须新开进程进行这些操作,而主进程进行其它操作,如提示进度;

开线程代码

public static final String getViaHttpsConnection(String url){
String respBody = ""; // return empty string on bad things
getViaHttpsConnectionThread urlThread = new getViaHttpsConnectionThread(143, url);
urlThread.start();
respBody = urlThread.getRespBody();
return respBody;
}

//新开线程处理联网
private static class getViaHttpsConnectionThread extends Thread {
getViaHttpsConnectionThread(long minPrime, String url) {
this.minPrime = minPrime;
this.url = url;
}

public void run(){
int rc = 0;
HttpConnection c = null;

try {
System.out.println("debug>UTIL open url:" + url + ";");
String isPhone = "false";

if ( DeviceInfo.isSimulator() ) {//不是虚拟机,必须设置false
isPhone = "true";
System.out.println("tip>no in phone;");
}

String useWifi = "";

if ( WLANInfo.WLAN_STATE_CONNECTED == WLANInfo.getWLANState() ){//如果有wifi就优先使用,不存在时再让手机自动走通道
useWifi = ";interface=wifi";
System.out.println("tip>contect by wifi");
}

c= (HttpConnection) Connector.open(url + useWifi + ";deviceside=" + isPhone + ";ConnectionTimeout=30000", Connector.READ, true);
c.setRequestMethod(HttpConnection.GET);
c.setRequestProperty("User-Agent", "Profile/MIDP-2.0 Configuration/CLDC-1.0");
c.setRequestProperty("Cache-Control", "no-store");
c.setRequestProperty("Connection", "close"); // not sure this is a good idea, but HTTP/1.0 might be less error-prone, some clients have trouble with chunked responses
System.out.println("debug>UTIL -- connection open;");

// Getting the response code will open the connection,
// send the request, and read the HTTP response headers.
// The headers are stored until requested.
rc = c.getResponseCode();
System.out.println("debug>UTIL -- got response code " + rc + ";");

// Get the length and process the data
int len = c.getHeaderFieldInt("Content-Length", 0);

System.out.println("debug>content-length="+len + ";");

byte[] data = Util.readFromHTTPConnection(c);
respBody=new String(data);
System.out.println("tip>respBody:" + respBody);
} catch (Exception e) {
respBody = "";//防止上级调用出错,清空
System.out.println("tip>urlthread error:" + e);
} finally {
if (c != null){
try {
c.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

if (rc != HttpConnection.HTTP_OK) {
try {
throw new OAuthServiceProviderException("tip>HTTP STATU: " + rc, rc, respBody);
} catch (OAuthServiceProviderException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

public String getRespBody(){
return this.respBody;
}

private String url = "";
private long minPrime = 0;
private String respBody = "";
}

如果没有新开线程,这个程序就会假死,导致手机也进行不了其它操作;
