我正在尝试在 Android 上启动一个非常简单的 jWebSocket 客户端并将其连接到我的本地服务器。我正在使用演示中的 JWC 类以及 jWebSocket 1.0 beta 8 和 Android 4.0.3,我的代码如下所示:
import org.jwebsocket.api.WebSocketClientEvent;
import org.jwebsocket.api.WebSocketClientTokenListener;
import org.jwebsocket.api.WebSocketPacket;
import org.jwebsocket.client.token.BaseTokenClient;
import org.jwebsocket.kit.WebSocketException;
import org.jwebsocket.token.Token;
import android.app.Activity;
import android.content.Context;
import android.content.IntentFilter;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.Spinner;
import cased.smids.communication.JWC;
public class TasksActivity extends Activity implements WebSocketClientTokenListener {
Spinner spinner;
Button btn_Start;
/** Called when the activity is first created. */
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
this.setContentView(R.layout.main);
JWC.init();
spinner = (Spinner)findViewById(R.id.sp_Task);
btn_Start = (Button)findViewById(R.id.btn_Start);
ArrayAdapter<CharSequence> adapter =
ArrayAdapter.createFromResource(
this,
R.array.Tasks,
android.R.layout.simple_spinner_item
);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
btn_Start.setOnClickListener(new View.OnClickListener() {
public void onClick(View src) {
switch (src.getId()) {
case R.id.btn_Start:
if (spinner.getSelectedItem().toString().equals("Connect")) {
try {
System.out.println("connecting manually...");
JWC.open();
} catch (WebSocketException e) {
e.printStackTrace();
}
}
default:
break;
}
}
});
}
@Override
protected void onResume() {
super.onResume();
System.out.println("* opening... ");
try {
JWC.addListener(this);
JWC.open();
} catch (WebSocketException ex) {
System.out.println("* exception: " + ex.getMessage());
}
}
@Override
protected void onPause() {
System.out.println("* closing... ");
try {
JWC.close();
JWC.removeListener(this);
} catch (WebSocketException ex) {
System.out.println("* exception: " + ex.getMessage());
}
super.onPause();
}
public void processClosed(WebSocketClientEvent arg0) {
System.out.println("closed");
}
public void processOpened(WebSocketClientEvent arg0) {
System.out.println("opened");
}
public void processOpening(WebSocketClientEvent arg0) {
System.out.println("opening");
}
public void processPacket(WebSocketClientEvent arg0, WebSocketPacket arg1) {
System.out.println("packet");
}
public void processReconnecting(WebSocketClientEvent arg0) {
System.out.println("reconnecting");
}
public void processToken(WebSocketClientEvent arg0, Token arg1) {
System.out.println("token");
}
}
所以基本上它只是一个微调器和一个按钮。现在,我要做的就是连接到我的本地 jWebSocketServer。演示应用程序(来自网站的 .apk 包,如果我导入代码 eclipse 告诉我在编译代码之前删除许多“@Overwrite” - 在发生相同的“错误”之后)适用于我的服务器,所以它必须成为代码。现在我得到的只是“连接......”,大约 0.1 秒后“关闭”。每次。
顺便提一句。该应用程序具有正确的 INTERNET 和 ACCESS_NETWORK_STATE 所以这应该不是问题。
我将不胜感激。
干杯
