I've currently got 2 PCs and a Smartphone running BOINC and belonging to BAM! Earlier this week I installed BOINC on my Android 5 tablet and added it to SETI@Home, which it is currently running. However, it continues not to show as a host in BAM. On my phone, there's a link to BOINCstats/BAM in the Projects tab. Using same Email and password on all hosts and projects. The projects tab on my tablet shows only my projects, and no BOINCstats/BAM link/menu.

However, the stats for this tablet are showing under BOINCstats and other stat sites.

Willy stated on 12/25, See https://boincstats.com/en/forum/18/10547 However, stats ARE working for my tablet under BOINCstats. The issue here is the acct. manager, BAM! How can the tablet communicate with stats but not with BAM? Thanks for followup.

Because they are two discrete functions; the stats site parses information taken from the "public" side of the projects, while the account manager handles the "private" functions of your projects, hosts, and preferences. Every single BOINC user will show up on the stats site, you have to sign up (and attach the BOINC Manager software on your hosts) in order to use the account manager.
