I need to find out if a particular contact is a member of a given group. I
have been working with the code below and have proved that it works using a
handset running Gingerbread. However I have been trying to run it on my HTC
One S running Android version 4.0.3 and it is failing. Has the API spec
changed?
public boolean checkGroupMembership(String groupID, String contactID, Context
ctx) {
ContentResolver groupContentResolver = ctx.getContentResolver();
String select = "contact_id=" + contactID +
" AND " + GroupMembership.GROUP_ROW_ID + " = " + groupID +
" AND mimetype='vnd.android.cursor.item/group_membership'";
Cursor contactGroupCursor =
groupContentResolver.query(
Data.CONTENT_URI,
new String[] { GroupMembership.CONTACT_ID,
GroupMembership.GROUP_ROW_ID, GroupMembership.IN_VISIBLE_GROUP },
select,
null,
null);
int records = contactGroupCursor.getCount();
try {
while(contactGroupCursor.moveToNext()){
String ContactID =
contactGroupCursor.getString(contactGroupCursor.getColumnIndexOrThrow(GroupMembership.CONTACT_ID));
String groupRowId =
contactGroupCursor.getString(contactGroupCursor.getColumnIndexOrThrow(GroupMembership.GROUP_ROW_ID));
String InVisiblegroup =
contactGroupCursor.getString(contactGroupCursor.getColumnIndexOrThrow(GroupMembership.IN_VISIBLE_GROUP));
Log.d("DEBUG", "groupSourceId in checkGroupMembership: " +
groupRowId + " InVisiblegroup = " + InVisiblegroup);
Log.d("DEBUG", "ContactID in checkGroupMembership: " +
ContactID);
}
}
finally
{
contactGroupCursor.close();
}
// see if the contact is in this group
if (records > 0) {
return true;
}
else {
return false;
}
}
}
In addition changing the query to purely find out what groups the contact
is a member of:
String select = "contact_id=" + contactID;
results in the following debug output. In some cases groupRowID looks like
a group ID, in others it is the contact number or the name of the contact.
Note that I am using my home landline to call test and this is appearing.
Also - I only have 10 groups defined on the handset and an id of 11, 12 and
13 is printed in the output... It could be that I'm missing something? I
definitely know that the contact_id I'm passing in is a member of the
Coworkers group (group_ID 5 on my phone) but this is never returned in ICS.
I have independently verified the group membership for HOME using contact
manager apps on both handsets.
