Question 1

How to install EOSIO Java SDK on Android?

Accepted Answer

Add the core and provider modules to your build.gradle, such as eosiojava and eosiojavasoftkeysignatureprovider. For Android, you must also set packagingOptions to exclude certain native libraries and use IntelliJ or command-line Gradle for building due to Android Studio limitations.

Question 2

EOSIO Java SDK vs JavaScript SDK for dApps?

Accepted Answer

Choose Java SDK for Android apps or Java backends where secure key storage (e.g., Android Keystore) is needed. JavaScript SDK is better for web-based dApps running in browsers, as it offers direct frontend integration without Java dependencies.

Question 3

How to sign transactions securely with EOSIO Java SDK?

Accepted Answer

Avoid the default softkey provider in production. Instead, use a secure signature provider like the Android Keystore Signature Provider, which interfaces with hardware-backed security modules to protect private keys from memory exposure.

Question 4

Does EOSIO Java SDK support smart contract testing?

Accepted Answer

The SDK focuses on transaction interaction, not contract deployment or testing. You'll need separate tools for compiling and deploying contracts, though the RPC provider can call relevant endpoints for contract actions once deployed.

Question 5

What Android versions does EOSIO Java SDK work with?

Accepted Answer

It requires Android 6.0 (Marshmallow) or higher due to Keystore security improvements. Older versions are unsupported, which may limit app distribution if targeting legacy devices.

Question 6

How to handle transaction errors in EOSIO Java SDK?

Accepted Answer

Implement error handling by catching exceptions from methods like signAndBroadcast and referring to the documented error model. Check response objects for status codes and use try-catch blocks for issues like network failures or invalid signatures.
