Just like everyone else who stores the db file on Google Drive and it does not work anymore. Interestingly  after I moved the db file to dropbox and it works from there. I have no ideas what Google did do to this db file on Google Drive. It probably is a Google problem instead of KeePassDroid. However  only KeePassDroid can find the work around on Google Drive. I do not think Google would help here.
