Passing custom object between activities

I'm following this tutorial on how to use MQTT with Android Studio. In it, they created an MQTTClient class that uses the MQTTAndroidClient library. I want to pass the MQTTClient class from one activity to another. Any suggestions how I might do this? I'm new to Android dev and I'm trying to negotiate serializable/parcelable tools without much know-how. Thanks!

P.S. I'm developing in Kotlin

Solution

  • Passing complex classes between activities is generally a bad idea. For that kind of usage you should use a Singleton and store it in your Application class or something like this.
