Take a look at that AOSP sources. You can see that the built in contacts app is saving the photos to the file system.
On the PhotoStore class in the contacts provider, here is the javadoc comment on the class: 1. /** 2. * Photo storage system that stores the files directly onto the hard disk 3. * in the specified directory. 4. */ https://android.googlesource.com/platform/packages/providers/ContactsProvider/+/master/src/com/android/providers/contacts/PhotoStore.java I know the subject tends to be a religious war, but I never store binary data in a database unless absolutely necessary. In this case, use the database to store an id or url of the photo, then have a specified file structure based on that id (could be one large directory with a photo named after each id). Remember, you can also use a content provider to provide access to the file system, so check that out as well.
