Well, I’m still vetting my HTC Sensation to see if it is a worthy replacement for my BlackBerry… Still not convinced as it happens. However, I have resolved one of my problems with it…<\/p>\n
IMAP sent\/trash\/draft folders don’t work properly if you have a “typical” IMAP server with a folder prefix of “INBOX.”. The IMAP NAMESPACE RFC (RFC2342<\/a>) defines how this works and how clients should handle it. As usual, Google developers figured they knew better than or just chose to ignore the RFC! As a result, the Andoird mail application doesn’t support folder prefixes, let alone automatically working correctly based on the namespace command.<\/p>\n If you are lucky and are using a IMAP server which does not have a personal namespace (Dovecot??) you might find the mail app works OK for you.<\/p>\n You can use the Android K9 mail client. I briefly tried it and it seemed to work. However, it doesn’t seem as “integrated” as the stock client so I gave up on it. It’s not a bad app – it just didn’t grab my attention. Luckily, there is a work around which is partially documented on the Android issues page at (thanks to those who posted there as it got me working on this workaround):<\/p>\n http:\/\/code.google.com\/p\/android\/issues\/detail?id=1811<\/a> in particular comment 83<\/a> and comment 84<\/a>.<\/p>\n The work around is to reconfigure the mail application’s SQLite database to point to IMAP provided folders rather than the default folders which do not work. On the surface it is pretty easy if your phone is rooted – no idea how I’d do this if the phone was not rooted.<\/p>\n The method I used in the end, to get around the SQLite database files being in use, was to boot to clockworkmod-recovery, mount \/data, adb the necessary files to the PC, edit the datafiles using SQLite and push them back using ADB.<\/p>\n The updating of the database is the trick. First, the ID of the account to be “fixed” needs to be determined. This account ID is then used to get a list of corresponding folders’ IDs from the mailboxs [sic]. These IDs and names are then used to update the accounts table which is the “magic bit”.<\/p>\n Here is the code snippet of the steps I followed. If you have a vague idea of technical stuff in this area, you should be able to follow the steps.<\/p>\n **boot into clockworkmod recovery ** copy the data files from the phone to your PC (might not have the -shm and -wal files):<\/p>\n ** run sqlite on the data files<\/p>\n ** based on output from above, determine the _id value for the account to modify (1<\/span> is used below in example):<\/p>\n ** the above will give a list of folder IDs and corresponding names. Hopefully, the _undecodename, _decodename and _shortname fields are equal. If not, then I’m not sure which you’d use in the step below – some trial and error might be needed, but I’d start with the _decodename values.<\/p>\n ** if you have a large number of IMAP folders and a “typical” IMAP server, the following should list the three needed folders and their associated IDs:<\/p>\n ** Once you have the folders’ _id values you use them in the commands below, changing the _sentfolderid, _trashfolderid and _draftfolderid values to correspond with those shown in the above step. Note to change the where clause to reflect the correct account _id used above.<\/p>\n ** back at your DOS prompt, delete the files on your phone (maybe mv instead for backup purposes?? – your choice) and push the updated files<\/p>\n **reboot the phone and hopefully all is working with the correct folders!!<\/p>\n <\/p>\n Note: If your phone has sqlite3 installed on it and it is rooted, you may be able to issue the above sqlite commands without having to boot into recovery mode. I’m not sure how well the mail app would behave with it’s configuration changing while it is running.<\/p>\n Note2: You do this at your own risk, etc etc. It worked for me. It might work for you – or it might not.<\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" Well, I’m still vetting my HTC Sensation to see if it is a worthy replacement for my BlackBerry… Still not convinced as it happens.
