  • Bump targetSdk to 34
• Library & App

    • Gradle to 8.10.2

v2.1.0

• library
  • breaking changes
    Fingerprinter.getFingerprintingSignalsProvider() returns a nullable type now.
    This is just a precaution measure though, and the likelihood of getting null from this method is super low. If you ever stumble upon such scenario, feel free to leave an issue.
    Also, this method has been annotated with WorkerThread annotation, which is meant be a hint to avoid using this method on the main thread as it might take enough time to skip a few frames.
  • behavioural changes
    • Previously, in case of some unexpected critical error in the library code, there was a chance that the callback passed to Fingerprinter.getFingerprint() or Fingerprinter.getDeviceId() methods would have never been fired.
      Now, this problem is resolved by returning some dummy result (currently, it's empty strings) and logging an error. As with Fingerprinter.getFingerprintingSignalsProvider(), this is more of a precaution measure, and we don't expect the library users to ever face such scenario. But if you do, feel free to leave an issue ;)
  • stability improvements
    As we were occasionally getting reports that some of the calls to the Android platforms APIs could never return on some devices, the timeout mechanism has been implemented. All the platform calls are safely wrapped now, so that none of such calls would be able to hang an entire library.
  • publishing improvement: the artifact includes the source code now
  • bumps of
    • kotlin to 1.9.10
    • compile sdk to 34
    • agp to 8.1.1
    • gradle to 8.3
• app
  • added the library version name into the nav drawer
  • added mouse drag support

v2.0.2

Changelog

Library

1. Fix for the issue #92

v2.0.1

Changelog

Library

1. Kotlin version update to 1.8.21
2. Maven publication improvement: include runtime dependencies (kotlin-stdlib and androidx.appcompat) into pom file
3. Minor bug fix: Fingerprinter.getSignalsMatching(V1, Stable/Optimal) now returns a proper list of signals that are used for fingerprintng with the same parameters. Check this PR for details.

Demo app

1. Fix: GSF ID / Android ID mixed up
2. Version bumps for dependencies

v2.0.0

The release contains new more convenient API. See the migration guide for details.

Changelog:

• Removed per-instance configuration. Use parameters for functions instead

• Add support for fully customisable fingerprint (now users can create fingerprints using only the signals they need)

• Provide a more convenient API for dealing with specific signals

• Remove the concept of signal group that introduced an extra complexity to the code without any sensible benefits
  significantly reduce the public API space. We had a lot symbols that were public by accident, polluting the namespace of our users and giving no extra value to the library.

• Document all public APIs. (Unfortunately, there is Kotlin/dokka#80 to reference overloaded methods in kdoc, so the documentation is not as nice as it could have been)

• Lazy signal evaluation. Previously, if we wanted to retrieve only one signal of the group, all signals of that group would be collected.

• Allowed reinstantiation. Previously, there was no way to retrieve the fingerprint twice using the same version. Not saying that this is essential, but probably nice to have for someone.

Everything stated as "removed" is in fact just deprecated for now, therefore "API v2" is fully backwards compatible.
