Migration from 1.5.x to 1.6.x

Edit on Github Send Feedback v1.9.0

PowerAuth Mobile SDK in version 1.6.0 is a maintenance release that brings multiple enhancements to both platforms:

  • Android SDK now depends on Android Jetpack libraries instead of the deprecated support library. This is most important for biometric authentication.
  • iOS SDK is no longer in conflict with 3rd party OpenSSL libraries. Our implementation still depends on OpenSSL, but the dependency is now hidden in precompiled PowerAuthCore dynamic framework.
  • iOS SDK has now unified class naming. So, no longer PA2 vs PowerAuth class prefixes.

Compatibility with PowerAuth Server

  • This release is fully compatible with PowerAuth Server version 0.24.x, 1.0.x and 1.1.x.

Android

API changes

  • PowerAuth mobile SDK now uses Jetpack libraries from androidx namespace as a replacement for old support library. If your application is still using the support library, then we highly recommend you to migrate your code to AndroidX.
  • PowerAuth mobile SDK now uses androidx.biometry for a biometric authentication, so you can upgrade this support library independently to PowerAuth mobile SDK. This is useful in case your users encounter a various device specific incompatibilities.
  • All biometry-related API calls no longer accept FragmentManager as a parameter. You can now choose between variants with Fragment or FragmentActivity at input:
    • PowerAuthSDK.commitActivation(Context, Fragment, String, String, String, ICommitActivationWithBiometryListener)
    • PowerAuthSDK.commitActivation(Context, FragmentActivity, String, String, String, ICommitActivationWithBiometryListener)
    • PowerAuthSDK.addBiometryFactor(Context, Fragment, String, String, String, IAddBiometryFactorListener)
    • PowerAuthSDK.addBiometryFactor(Context, FragmentActivity, String, String, String, IAddBiometryFactorListener)
    • PowerAuthSDK.authenticateUsingBiometry(Context, Fragment, String, String, IBiometricAuthenticationCallback)
    • PowerAuthSDK.authenticateUsingBiometry(Context, FragmentActivity, String, String, IBiometricAuthenticationCallback)
    • All above methods must be called from UI thread, otherwise IllegalStateException is thrown.
  • The BiometricDialogResources class containing resource IDs for the biometric authentication has been heavily reduced. Please review the actual usage of the resources carefuly.
    • The BiometricDialogResources.Strings section has been reduced. The old section constructor is now deprecated and you can review what strings are still in use.
    • The BiometricDialogResources.Drawables section has been reduced. The old section constructor is now deprecated and you can review what images are still in use.
    • There’s no longer BiometricDialogResources.Colors section.
    • There’s no longer BiometricDialogResources.Layout section.
  • SDK no longer provide functions to detect root on device.
  • All PowerAuthErrorCodes.PA2ErrorCode* constants are now deprecated. You can use a new constants with a standard naming for a replacement. For example PA2ErrorCodeNetworkError is now NETWORK_ERROR.
  • The following classes and interfaces are now deprecated:
    • PA2System class is now PowerAuthSystem
    • PA2Log class is now PowerAuthLog
    • PA2ClientValidationStrategy interface is now HttpClientValidationStrategy
    • PA2ClientSslNoValidationStrategy class is now HttpClientSslNoValidationStrategy
    • Otp class is now ActivationCode available in package io.getlime.security.powerauth.core
    • OtpUtil class is now ActivationCodeUtil available in package io.getlime.security.powerauth.core

Other changes

  • If your application is using an asymmetric cipher protecting the biometric key (e.g. PowerAuthKeychainConfiguration.isAuthenticateOnBiometricKeySetup is false), then the methods configuring new biometric key may take a longer time calculating the key-pair on the background thread. The PowerAuth mobile SDK doesn’t display any biometric authentication dialog in this case, so your application’s UI should display some activity indicator. The following methods are affected by this change:
    • PowerAuthSDK.commitActivation(Context, Fragment | FragmentActivity, String, String, String, ICommitActivationWithBiometryListener)
    • PowerAuthSDK.addBiometryFactor(Context, Fragment | FragmentActivity, String, String, String, IAddBiometryFactorListener)
  • PowerAuthSDK.createActivation(...) methods now reprots a slightly different error codes when invalid activation or recovery code is provided. If your application properly validate input data with using ActivationCodeUtil, then this change should not affect your code.

iOS & tvOS

The main change in this SDK version is that SDK is now composed from two dynamic frameworks:

  • PowerAuthCore - module contains low level implementation and has embedded OpenSSL.
  • PowerAuth2 - module contains all high level SDK source codes and depends on PowerAuthCore

Version 1.6.6 increased minimum required iOS & tvOS deployment target to 11.0. See Xcode14 support.

API changes

  • All public objects, protocols, enums, constants and functions now have PowerAuth prefix. All previously declared PA2* interfaces are now declared as deprecated.
    • For example, PA2ActivationStatus is now deprecated and you should use PowerAuthActivationStatus instead. The similar rename can be applied for all deprecated interfaces.
    • This change normally works well for swift enumerations, because enumeration values are mangled to a short names, like .removed. For ObjC projects, it’s recommended to use project-wide find’n’replace. For example, for PA2ActivationState_ you can replace all occurrences to PowerAuthActivationState_.
    • You may encounter a several compilation errors at the beginning. If so, then it’s recommended to fix the deprecation warnings first, because that may also solve that compilation errors.
  • ECIES routines are now provided by new PowerAuthCore module, so in case your application depends on our E2E encryption scheme, then you have add import PowerAuthCore first and then fix the deprecated warnings.
  • SDK no longer provide functions to detect jailbreak on device.
  • PowerAuthActivation object constructor now throws an error in Swift. If you don’t care about the error, then use try? statement to achieve previous constructor behavior.

Changes in 1.6.6+

Xcode14 support

Due to changes in Xcode 14, bitcode is no longer supported and we had to increase minimum supported OS to the following versions:

  • iOS 11.0
  • tvOS 11.0
  • watchOS 4.0

If you still have to compile our SDK for older operating systems, then you need to build the library manually with Xcode older than 14.0. For example:

  1. Clone repository 
    git clone --recursive https://github.com/wultra/powerauth-mobile-sdk.git
cd powerauth-mobile-sdk
git submodule update
  2. Make sure that xcodebuild is older than 14.0: 
    % xcodebuild -version
Xcode 13.2.1
Build version 13C100
  3. Build library with legacy architectures and bitcode: 
    ./scripts/ios-build-sdk.sh buildCore buildSdk --legacy-archs --use-bitcode --out-dir ./Build

    Similar command is available for app extensions and watchos:

    ./scripts/ios-build-extensions.sh extensions watchos --legacy-archs --use-bitcode --out-dir ./Build

If you use cocoapds for PowerAuth mobile SDK integration, then please let us know and we’ll prepare a special release branch for you.
