- TronLinkSDK-Android is a tool that helps third-party apps simplify account-level operations and provide core wallet logic for queries, transactions, signatures, etc.
- TronLinkSDK-Android will provide the corresponding aar package, you can choose the way to introduce online (...), or put the aar package we provide into the corresponding Studio - lib directory, please see us for detailed access. Official demo provided
- TronLinkSDK-Android will restore the syntax of Tron-web as much as possible. We will provide interface - ITronLinkSdk to streamline the operation and explain the fields.
