drools engine and android ?

[Cyrille M.]

Hi,

I was wondering if there is a way to use drools as expert system embeded into an android app.

The best way for me would be to pre-compile a set of rule tobe triggered afterward on the app.

i've already seen the "dr-drools-android-demo" project, i've made few poc but i've been unlucky.

If you know a way to do it, that would be fantastic :)

Some people have had success, but I don’t think it works out of the box. we are working towards this for 2015:

Thank's Mark,
i don't think it meet my need :

i want to compile&serialise the rules with my local jvm (on a server)
then send the serialized rules to my android app to be deserialized and executed by the dalvik vm.

do you think that can be done ?

As I previously mentioned people have managed to get Drools runtime working on android, but not “out of the box”.

You’ll need to google, and you’ll find stuff like this:

https://github.com/kedzie/drools-android

http://stackoverflow.com/questions/8646934/integration-of-drools-expert-system-with-android-projects

"I forked Drools 6 and modified it to use Dex for class generation and it works on Android (using serialized packages compiled on desktop) I put an Android application sample on github”

The last one claims that it all works

thank's again, i've already looked to the github source but the example is not working cause it's rules less :s

and i didn't manage to build a running app on android.

on a standard jvm it works just fine. but when i'm porting my dev to android it's a bit of a mess.
i'll keep looking into it.
