The APK released to the Play Store has versionCode set to 29 instead of 28,
because the update had to be resubmitted due to an erroneous rejection by
Google.
I kept the classes in the encoding package and turned them into wrappers for
Guava. I also changed the functions in the Base32 class to take and return
strings insteads if character arrays.
This patch replaces the usage of the deprecated FingerprintManager API with
BiometricPrompt. This uses the Android X library, so we get the native biometric
prompt on recent versions of Android and a Google-made one on older versions. By
not working with custom prompts for biometric authentication like we do now, we
can be sure that any issues like #70, #81, #237 are not actually our fault.
Here's what it looks like:

As a nice aside, this also adds support for the new facial recognition as an
authentication method on Pixel 4 phones.
This is still a draft, but early feedback is welcome.
This also fixes an issue with the use of the Iconics library where it was
initialized twice. I also removed the dependency to [AndroidX Preference
eXtended](https://github.com/takisoft/preferencex-android), as there don't seem
to be any issues with using the vanilla AndroidX preference library anymore.
This patch introduces the new ``UUIDMap`` type, reducing code duplication and
making UUID lookups faster. We currently already use UUIDs as the identifier for
the ``DatabaseEntry`` and ``Slot`` types, but the way lookups by UUID work are
kind of ugly, as we simply iterate over the list until we find a match. As we're
probably going to have more types like this soon (groups and icons, for
example), I figured it'd be good to abstract this away into a separate type and
make it a map instead of a list.
The only thing that has gotten slower is the ``swap`` method. The internal
``LinkedHashMap`` retains insertion order with a linked list, but does not know
about the position of the values, so we basically have to copy the entire map to
simply swap two values. I don't think it's too big of a deal, because swap
operations still take less than a millisecond even with large vaults, but
suggestions for improving this are welcome.
I had to update gradle and JUnit to be able to use the new ``assertThrows``
assertion method, so this patch includes that as well.
This patch adds a dependency to glide to handle the loading and caching of
icons. In my testing it eliminated the lag previously experienced in the main
activity when quickly scrolling through a large list of entries. It does add an
extra 1MB to the APK size, but I think that's acceptable for the amount of
complexity it handles for us.
