Leshan with android

[YassineElyk]

Hello everyone,

I'm wondering if a Leshan client can be deployed on an android board? If so, what are the things I need to consider before doing this?

Thank you for your help.

I never tested it, but we based our code on californium(CoAP stack) and I know that some people use it on android.

Did you test Leshan client on android ? If yes could you quickly explain what you have done ? and which problems you face ? and we could try together to make it works.

I have successfully tested the above client previously. It looks like an Ericsson demo based on the objects created. So short answer is yes I think you can get it working but no you can't just run the Leshan client demo.

Here another example of Leshan used with Android : https://github.com/xgswust/leshan-android-demo (from #719)

In #800, I activate animal-sniffer-maven-plugin for ensure we don't use class signature which are not present in android.

This will not guarantee that all Leshan API will works correctly but at least that we don't use class which is not present in Android framework.

Animal sniffer is activated on main module (core, core-cf, server-core, server-cf, client-core, client-cf) but not for *-demo and server-redis as it seems this does really makes senses.

Currently Leshan target android-api-level-19/4.4.2 (aka KitKat) which should cover a great part of android devices.

About leshan dependencies :

• californium target android-api-level-16/4.1.2
• minimal-json : I check quickly and it sounds Ok for android-api-level-19/4.4.2
• slf4j-api : I didn't test it but I would be surprised if this was not compatible.

I updated the F.A.Q by adding a question about android.

I close this issue as there is not so much we can do now.

(Except maybe develop an android demo ? 🤔 )
