问题
Does anyone know of an MQTT broker that runs on an Android smartphone? I tried to Google and found nothing, and on the app store there seems to be only one app with just 10 downloads, so I'm not sure how well it works.
回答1:
Add these dependencies to the gradle
dependencies{
compile 'io.moquette:moquette-netty-parser:0.8.1'
compile 'io.moquette:moquette-broker:0.8.1'
compile 'io.moquette:moquette-parser-commons:0.8.1'
}
And use
io.moquette.server.Server server = new io.moquette.server.Server();
server.startServer();
to start broker server. the default URI is tcp://localhost:1883
For me server.startServer();
gave me exception as it is unable to create a file BrokerConstants.DEFAULT_MOQUETTE_STORE_MAP_DB_FILENAME
.
So, I changed the destination of the BrokerConstants.DEFAULT_MOQUETTE_STORE_MAP_DB_FILENAME
using this code below code and it worked for me.
try {
MemoryConfig memoryConfig = new MemoryConfig(new Properties());
memoryConfig.setProperty(BrokerConstants.PERSISTENT_STORE_PROPERTY_NAME, Environment.getExternalStorageDirectory().getAbsolutePath()+ File.separator + BrokerConstants.DEFAULT_MOQUETTE_STORE_MAP_DB_FILENAME);
server.startServer(memoryConfig);
// server.startServer();//is not working due to DEFAULT_MOQUETTE_STORE_MAP_DB_FILENAME;
Log.d(TAG,"Server Started");
}
catch (IOException e) { e.printStackTrace(); }
catch (Exception e){ e.printStackTrace(); }
And Use Paho libraries for android
compile 'org.eclipse.paho:org.eclipse.paho.client.mqttv3:1.1.0'
compile 'org.eclipse.paho:org.eclipse.paho.android.service:1.1.1'
To create a client and connect to tcp://localhost:1883
and subscribe for a topic and start publishing and receiving messages.

Here is an MQTT broker library I have adapted to Android: https://github.com/interaktionsbyran/moquette You'll have to make your own Android app though, it is just a library.

Have a look at this question:
Using Android-Tablet as an MQTT-Server
TLDR;
Possible, have a look for a pure Java broker like HiveMQ.
