we are proud to announce the release v2.2.1 of the aepp-sdk-java . With the support of the æternity crypto foundation as well as the active support within the forum and devchat we were able to improve the SDK and enhance its functionalities to interact more securely with the æternity blockchain.
The aepp-sdk-java empowers Java , Kotlin and Scala developers to interact with the æternity blockchain.
We worked hard on improving stability , robustness and comfort of usage while keeping maintainability and flexibility.
The SDK realizes a generic approach to provide support for every kind of transaction types based on strongly typed models:
- thus a developer just need to create a model for a certain transaction type and the mapping, byte transformation and interaction is executed transparently
Features & transactions types
- Compiling of contracts
- Encoding and decoding of data and results
- Communication with the middleware to retrieve information about auctions
Although we already prepared TX types to support State Channels these can NOT be handled using the SDK.
All methods provided by the SDK can be exectued either blocking or asynchronous depending on use case and programming style. The SDK provides methods to retrieve information about current and mined transactions and blocks as well as information concerning accounts.
Furthermore the SDK provides useful utilities to cover typical use cases
- generate and restore of KeyPairs
- support creation and recovery of HD-wallets
- generate and restore of Keystores
- automatic fee calculation for all transaction types supported by the SDK
- unit conversion tool
- various util libraries to encode, decode and sign
The SDK can easily be configured to support devnet , uat or mainnet and other key parameters.
Furthermore, with the release v1.0.0 of the contraect-maven-plugin we provide a new tool similar to the web3j-codegen for Ethereum which makes it a piece of cake to deploy and interact with Sophia smart contracts on the æternity blockchain.
- READ MORE about the contraect-maven-plugin
- there are some limitations and general information you need to know when developing an android application using the SDK
- you can help us improving the current state and join the discussion here:
- we used this application to perform the first claim of an ÆNS name ever on the æternity blockchain!
