how many apps can share with same sharedUserId ?

[Terry Kim]

Hello,

In android developer web site, there are two explanation about
sharedUserID. but I don't know which one is correct.

The first one is,

http://developer.android.com/guide/topics/security/security.html,

"Note that in order to retain security, only two applications signed
with the same signature (and requesting the same sharedUserId) will be
given the same user ID."

The second one is

http://developer.android.com/reference/android/R.attr.html#sharedUserId

" By default, each package gets its own unique user-id. By setting
this value on two or more packages, each of these packages will be
given a single shared user ID, so they can for example run in the same
process."

So my question is how many apps can share with same sharedUserId? only
two or more?

Count is not relevent.  "two applications signed with the same signature" just means to consider two applications blah blah.
