wallet-sdk-gomobile

Wallet SDK Gomobile

This package contains the gomobile-compatible version of the SDK. It acts as a wrapper for the Go SDK.

Prerequisites

• Go 1.22 or newer
• The gomobile tools:

  go install golang.org/x/mobile/cmd/gomobile@latest
  gomobile init
  

• $GOPATH/bin added to your path

Android Bindings

• Android SDK (installable via the SDK Manager in Android Studio)
• Android NDK (installable via the SDK Manager in Android Studio)
• JDK

iOS Bindings

• A Mac
• Xcode Command Line Tools - these are included with Xcode, but can also be installed standalone with xcode-select --install
• Agreed to the Xcode licence agreement prompt via Terminal. Creating the iOS bindings will trigger the prompt if you haven't agreed to the licence yet

Generating the Bindings

To generate both the Android and iOS bindings in one command:

make generate-all-bindings

To generate only the Android bindings:

make generate-android-bindings

To generate only the iOS bindings:

make generate-ios-bindings

The generated bindings can be found in the bindings folder.

Helpful Tips

• After importing walletsdk.aar into your Android project, to use the Wallet SDK packages in a Kotlin or Java file, you import them in a roughly similar way as you would the equivalent Go package:

  // Follow the pattern below for other packages/types as well
  import dev.trustbloc.wallet.sdk.api.*;
  import dev.trustbloc.wallet.sdk.openid4ci.*;

• After importing the iOS bindings into Xcode, to use the Wallet SDK in a Swift file, add the following:

  // This imports everything
  import Walletsdk

  To use the Wallet SDK in an Objective-C file, do the following:

  #import <Walletsdk/Walletsdk.h>

  Alternatively, you can import individual files. For example:

  #import <Walletsdk/Api.objc.h>
  #import <Walletsdk/Storage.objc.h>

  Note that the various types, interfaces and methods will have the package names prefixed to them (e.g. Signer in Go becomes CredentialsignerSigner in Swift and Objective-C).
• If you've regenerated bindings on your machine, make sure you update your Android Studio or Xcode project accordingly.
