Hello. My app working fine on Debug or Release mode but prepared/compiled EXE crash after using Internal Packager. I think I need to add some #PackagerProperty for jMQTT.
Please take a look on the log:

java.lang.IllegalArgumentException: no NetworkModule installed for scheme "tcp" of URI "tcp://myserver.com:1883"

Thanks for help in advance.

If using jMQTT v1.25 perhaps refer to https://www.b4x.com/android/forum/threads/jmqtt-official-mqtt-client.59472/ where it advises:

If building a standalone package then add this to the main module:

B4X:
#PackagerProperty: AdditionalModuleInfoString = provides org.eclipse.paho.client.mqttv3.spi.NetworkModuleFactory with org.eclipse.paho.client.mqttv3.internal.TCPNetworkModuleFactory, org.eclipse.paho.client.mqttv3.internal.SSLNetworkModuleFactory,  org.eclipse.paho.client.mqttv3.internal.websocket.WebSocketNetworkModuleFactory, org.eclipse.paho.client.mqttv3.internal.websocket.WebSocketSecureNetworkModuleFactory;
