Android websocket详细使用方法

里面加入了断线重连、心跳机制、退出释放资源，废话不多直接开干
1.添加依赖

implementation "org.java-websocket:Java-WebSocket:1.5.1"

2、添加使用类

import android.util.Log;
import org.java_websocket.client.WebSocketClient;
import org.java_websocket.drafts.Draft_6455;
import org.java_websocket.handshake.ServerHandshake;
import java.net.URI;
import javax.net.ssl.SSLParameters;

public class JWebSocketClient extends WebSocketClient {
    
    
    @Override
    protected void onSetSSLParameters(SSLParameters sslParameters) {
    
    
        //super.onSetSSLParameters(sslParameters);
    }

    public JWebSocketClient(URI serverUri) {
    
    
        super(serverUri, new Draft_6455());
    }

    @Override
    public void onOpen(ServerHandshake handshakedata) {
    
    
        Log.e("JWebSocketClient", "onOpen()");
    }

    @Override
    public void onMessage(String message) {
    
    
        Log.e("JWebSocketClient", "onMessage()");
    }

    @Override
    public void onClose(int code, String reason, boolean remote) {
    
    
        Log.e("JWebSocketClient", "onClose()" + reason + "-****-" + remote);
    }

    @Override
    public void onError(Exception ex) {
    
    
        Log.e("JWebSocketClient", "onError()" + ex);
    }
}

3、在代码中的使用

public class BloodSugarActivity extends BaseActivity {
    
    
    String TAG="BloodSugarActivity";
    public JWebSocketClient client;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
    
    
        super.onCreate(savedInstanceState);
        getSupportActionBar().hide();
        setContentView(R.layout.activity_blood_sugar);
    }

    @Override
    protected void onResume() {
    
    
        super.onResume();

        mHandler.postDelayed(heartBeatRunnable, HEART_BEAT_RATE);//开启心跳检测
        if (client == null) {
    
    
            Log.e(TAG, "``````````````````````onResume");
            initWebSocket();
        } else if (!client.isOpen()) {
    
    
            reconnectWs();//进入页面发现断开开启重连
        }
    }

    @Override
    protected void onStop() {
    
    
        super.onStop();
        Log.e(TAG, "``````````````````````````````onStop");
    }

    @Override
    protected void onDestroy() {
    
    
        super.onDestroy();
        Log.e(TAG, "`````````````````````````onDestroy");
        closeConnect();
    }
    
    /**
     * 初始化websocket

    public void initWebSocket() {
    
    
        Log.e(TAG, "websocket的地址是：we://" + SpUtils.decodeString("websocketurl"));
        URI uri = URI.create("ws://" + SpUtils.decodeString("websocketurl"));
        //TODO 创建websocket
        client = new JWebSocketClient(uri) {
    
    
            @Override
            public void onMessage(String message) {
    
    
                super.onMessage(message);
                if (!message.equals("Heartbeat")){
    
    
                    LogUtils(TAG, "websocket收到消息：" + message);
                }
            }

            @Override
            public void onOpen(ServerHandshake handshakedata) {
    
    
                super.onOpen(handshakedata);
                LogUtils(TAG, "websocket连接成功");

            }

            @Override

自此就可以使用websocket了。。。
