离线打包后手写websocket

用到的jar包 android-support-v4.jar

package com.websocket;

import java.io.IOException;
import java.util.ArrayList;
import com.koushikdutta.async.callback.CompletedCallback;
import com.koushikdutta.async.http.AsyncHttpClient;

public class HWebSocket extends StandardFeature{
private static int tryTime = 1;
private static WebSocket webSocket = null;
public static void webConnect(final String url) {

if (webSocket == null) {
try {

AsyncHttpClient.getDefaultInstance().websocket(url, null, new WebSocketConnectCallback() {
@Override
public void onCompleted(Exception ex, WebSocket _webSocket) {
if(ex!=null) {

//获取webview
ArrayList<IWebview> ss = SDK.obtainAllIWebview();
for (IWebview iWebview : ss) {
iWebview.evalJS("onClosed('0')");
}
ex.printStackTrace();
}
webSocket = _webSocket;
webSocket.setStringCallback(new WebSocket.StringCallback() {
@Override
public void onStringAvailable(String s) {
Log.d("websocket",s);
//获取webview

// }
}
}
});
webSocket.setClosedCallback(new CompletedCallback() {

}catch(Exception e){
//socket关闭时候事件触发
ArrayList<IWebview> ss = SDK.obtainAllIWebview();
for (IWebview iWebview : ss) {
// if (iWebview.getOriginalUrl().equals("messageList.html")) {
iWebview.evalJS("onClosed('0')");
};
e.printStackTrace();
}
finally {

// webConnect(url);
// }

// break;
// };
}
}
}

//发送socket
public static void sendMsg(String msg) {
// show(msg);
if (webSocket != null && webSocket.isOpen()) {
Log.d("c", msg);
webSocket.send(msg);
Log.d("s",webSocket.isOpen()+"");
}
}

//关闭socket
public static void close() {
if (webSocket != null && webSocket.isOpen()) {
webSocket.close();
webSocket = null;
}
}

//检查ip是否畅通
public static String pingIpAddress(String ipAddress) {
String falg = "false";
Process process = null;
try {
process = Runtime.getRuntime().exec("ping -c 1 -i 0.5 -W 1 " + ipAddress);
int status = process.waitFor();
if (status == 0) {
falg = "true";
} else {
falg = "false";
}
} catch (IOException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
}
return JSUtil.wrapJsVar(falg);
}

}

js端代码

//socket 返回值
function wsRecive(e) {

}

// 0 错误断开 1 自然断开
function onClosed(e) {
if(e == '0') {
var ws = plus.webview.currentWebview();

if(ws.id=='entrance'){
return;
}
var ars = plus.webview.getDisplayWebview();
if(ars[ars.length-1].id==ws.id){
mui.alert("连接已断开，请重启程序");
}

}
}

//关闭socket方法
var close = function() {
var Toolkit = null;
try{
Toolkit = plus.android.importClass("com.websocket.HWebSocket");
if(Toolkit) {
Toolkit.close();
} else {
plus.nativeUI.alert("IM服务器连接失败");
}
}catch(e){
return false;
}
}
