Not working on Android - Githubissues

prameetchakraborty commented 6 years ago

The package works perfectly on iOS. However, when I run on Android, with the exact same parameters and code, I get this (AMQJS0007E Socket error:undefined). Any solutions?

Hello,

If you try to run directly with the example code, there seems to be a mistake in it (I'm running on Android). A quick look at Paho's source code shows that a call to new Paho.MQTT.Client() has different behaviors depending on the numbers of arguments you give it.

2 arguments : first one has to be the full path, second one is client id,
3 arguments : the first one has to be the host name (ws:// is automatically appended), second is port, third is client id, but for some reason that I do not know, /mqtt gets automatically appended as a relative path.
4 arguments : first is hostname, second is port, third is path, fourth is client id.

Tl;dr: These are are valid ways to connect but @Introvertuous 's example is flawed

// the two open brokers provided by eclispe are:
//    ws://iot.eclipse.org:80/ws (non SSL)
//    ws://iot.eclipse.org:443/ws (SSL)

// this will resolve to ws://iot.eclipse.org:443/ws => ok
const client = new Paho.MQTT.Client(
  'ws://iot.eclipse.org:443/ws',
  'clientId'
);

// this will resolve to ws://iot.eclipse.org:443/mqtt => does not exist!
const client = new Paho.MQTT.Client(
  'iot.eclipse.org',
  443,
  'clientId'
);

// this will resolve to ws://iot.eclipse.org:443/ws => ok
const client = new Paho.MQTT.Client(
  'iot.eclipse.org',
  443,
  '/ws',
  'clientId'
);

That might solve your issue?

@nicolascouvrat is correct, but for some reason, the example I created did work properly (messages were received on the other end of the socket). I will fix that when I get a chance but I have a feeling this error is being caused by something else.

How to set with server ip address instead or using 'iot.eclipse.org', and '443'. Means I want to say can we use Ip address like: '192.21.23.210' and port number '1883'. If anybody know, please reply. I already try, but in android is not working!!

My app works fine in debug, but when I generate the release apk I get AMQJS0007E (same device, same network). Any ideas?

我的应用程序在调试中运行良好，但是当我生成发行版APK时，我得到了AMQJS0007E（同一设备，相同网络）。有任何想法吗？

我也遇到相同问题了，您的问题解决了吗

如何设置服务器IP地址或使用“ iot.eclipse.org”和“ 443”。就是说我想说我们可以使用Ip地址，例如：“ 192.21.23.210”和端口号“ 1883”。如果有人知道，请回复。我已经尝试过了，但是在android中不起作用！

请问您的问题解决了吗，我和您遇到了相同的问题

你好，

如果您尝试直接使用示例代码运行，则似乎有误（我在Android上运行）。快速浏览Paho的源代码可知，new Paho.MQTT.Client()根据您提供的参数数量，对的调用具有不同的行为。

2个参数：第一个必须是完整路径，第二个是客户端ID，

3个参数：第一个必须是主机名（ws://自动添加），第二个是端口，第三个是客户端ID，但是由于某种原因（我不知道），/mqtt会自动添加为相对路径。

4个参数：第一个是主机名，第二个是端口，第三个是路径，第四个是客户端ID。

Tl; dr：这些是有效的连接方式，但是@Introvertuous的示例存在缺陷
// eclispe提供的两个开放代理是：
//     ws：//iot.eclipse.org：80 / ws（非SSL）
//     ws：//iot.eclipse.org：443 / ws（SSL）

//这将解析为ws：//iot.eclipse.org：443 / ws =>好的
const  client  =  new  Paho.MQTT.Client（
   ' ws：//iot.eclipse.org：443 / ws '，
   ' clientId '
）;

//这将解析为ws：//iot.eclipse.org：443 / mqtt =>不存在！
const  client  =  new  Paho.MQTT.Client（
   ' iot.eclipse.org '，
   443，
   ' clientId '
）;

//这将解析为ws：//iot.eclipse.org：443 / ws =>好的
const  client  =  new  Paho.MQTT.Client（
   ' iot.eclipse.org '，
   443，
   ' / ws '，
   ' clientId ' 
）;
那可以解决您的问题吗？

我是用您的事例还是连接失败，请问有什么好的解决方法吗

@chentianci123 , 你好，你的问题解决了吗？我现在遇到了同样的问题，我查看资料好像是说这个插件只支持websocket，不支持TCP

Hi! I was able to get the release APK working by adding android:usesCleartextTraffic="true" to <application> on android/app/src/main/AndroidManifest.xml

  <application
    ...
    android:usesCleartextTraffic="true">
