vcard4android

vcard4android is an Android library that brings together VCard and Android. It's a framework for

  • parsing and generating VCard resources (using ez-vcard) from/into data classes that are compatible with the Android Contacts Provider, and
  • accessing the Android Contacts Provider by a unified API.

It has been primarily developed for DAVx⁵ and is currently intended to be used as git submodule.

  • Support IS_READ_ONLY for Data and Group rows

    Support IS_READ_ONLY for Data and Group rows

    Currently, we have support for the RAW_CONTACT_IS_READ_ONLY flag.

    However Contacts apps can still change the data rows of read-only contacts (and quite everything is a data row, for instance the name). So for native contacts read-only support, we need

    • [x] IS_READ_ONLY support for Data rows (like we had it before the rewrite to data row builders)
    • [x] GROUP_IS_READ_ONLY support for AndroidGroup
    • [x] Tests

  • Save contact photo into assets instead of PHOTO blob

    Save contact photo into assets instead of PHOTO blob

    Raw-contact photos can be saved either

    1. by inserting the photo directly into the database (PHOTO column), or
    2. by writing into the contact photo asset. This method allows arbitrary photo sizes, processes the photo, generates a thumbnail automatically etc.

    Because of its advantages, method 2 should be used when possible. There is however a problem which has forced us to use method 1 until now:

    1. Assume we're within a sync and currently inserting a contact. All data rows except the photo have already been inserted.
    2. Insert the photo as an asset. As soon as the photo is transferred, the contact provider starts a background thread that processes the photo.
    3. Now the sync of this is complete and the dirty flag is reset.
    4. The background thread takes some time and then sets the raw contact photo. Unfortunately, it triggers DIRTY=1 again regardless of whether the asset URI was constructed with caller_is_syncadapter or not.
    5. So the contact is now dirty again and will be uploaded again etc.

    We should give another try to use method 2 if any possible. Useful information:

    • ContactsProvider2 uses a write lock when updating the photo. Maybe an update with DIRTY=0 some time after inserting the photo would block until the photo is actually inserted.
    • ContactsProvider2Test and some other projects simply wait until the photo data row is available. However then we need a timeout, and what for instance if photo insertion failed?
