paho.mqtt.android

Paho Mqtt Android package for sdk version 31 or above.

✔️ Issue made

paho.mqtt.android package from eclipse currently has issue at sdk version upper than 31.
This is because, PendingIntent class from Android has been changed according to:
https://developer.android.com/about/versions/12/behavior-changes-12#pending-intent-mutability

✔️ Current status

The error is still opened as: eclipse#485, so if you want to retrieve any .jar from the package, refer followings.

• Reference is here: eclipse#485 (comment)
  
• I've modified more build configurations to build package rather than copying whole codes.

💛 How to build

➡️ Build from source

1. Clone following repositories at the same path

• https://github.com/doorooful/paho.mqtt.android
• https://github.com/eclipse/paho.mqtt.java

2. Move to paho.mqtt.android directory from terminal

3. Run following script from terminal:

• windows: .\gradlew.bat clean org.eclipse.paho.android.service:assemble org.eclipse.paho.android.service:publish

4. Find .jar file from build output directory:

• Location: ~/paho.mqtt.android/org.eclipse.paho.android.service/build/libs/
• File: org.eclipse.paho.android.service-1.1.1.jar (.aar outputs are under ~/paho.mqtt.android/org.eclipse.paho.android.service/build/outputs/aar)

💛 How to apply from Android Studio

1. add .jar file under the app/lib from project view

2. add implementation files dependencies:

dependencies {
    ...
    implementation files('lib/org.eclipse.paho.client.mqttv3-1.2.5.jar')
    implementation files('lib/org.eclipse.paho.android.service-1.1.1.jar')
    ...
}

3. Finally, you can change sdk version! -> 31 or above!
