Is it possible or a good practice?

It depends on what are you planning to do. AndroBOINC is just a manager with which you can connect to other BOINC clients and do some basic operations. But as I can see it looks like it isn't mainained anymore.

So, it's best to just leave it alone? Thanks

If you don't need it then, yes.

Read carefully, Andrew, very carefully. Notice Kyong said androboinc is just a manager that you can use to connect to BOINC clients. Many people are not aware that there is a BOINC client as well as a BOINC manager. A BOINC manager only allows you to control BOINC client. A manager does not run project applications, that's what the client does. Therefore if you were thinking you might be able to use androboinc to run tasks on a phone/tablet/whatever then no, that won't work, stay away from it.

If, however, you want to leave BOINC client running on your computer at home while you go on a trip and you want to use your android phone/tablet/whatever to check on how that client is doing and possibly interact with it then you might try androboinc on your phone/tablet/whatever. But bear in mind neither BOINC client nor project apps would be running on the phone/tablet/whatever, only the manager (androboinc) would be running on the phone.
