The Eclipse Paho Java Client is an MQTT client library for the JVM and Android, providing both asynchronous (MqttAsyncClient) and synchronous (MqttClient) APIs for MQTT v3 and v5. It is part of the Eclipse Paho IoT project for reliable open-standard M2M messaging.

Use cases

• connect a Java application to an MQTT broker
• publish and subscribe to MQTT topics from Android
• implement IoT device messaging on the JVM
• use MQTT v5 features in Java
• build asynchronous pub/sub messaging with callbacks
• send telemetry from a Java backend to an MQTT broker

When to choose

• you need a mature, Eclipse-backed MQTT client for Java or Android
• you want both synchronous and asynchronous MQTT APIs
• you need MQTT v3 and v5 support on the JVM

When to avoid

• you need an actively developed client with frequent releases
• you are not on a JVM-compatible platform
• you need MQTT-SN or other non-TCP transports
