# Welcome to EthereumJ for Android # About EthereumJ is a pure-Java implementation of the Ethereum protocol. For high-level information about Ethereum and its goals, visit [ethereum.org](https://ethereum.org). The [ethereum white paper](https://github.com/ethereum/wiki/wiki/%5BEnglish%5D-White-Paper) provides a complete conceptual overview, and the [yellow paper](http://gavwood.com/Paper.pdf) provides a formal definition of the protocol. This is an Android-optimized fork of [EthereumJ](https://github.com/ethereum/ethereumj). This repository consists of: * [ethereum-core](ethereumj-core): a android compatible library of ethereumj-core . * [app]: a simple mockup GUI for exploring Ethereum functionality and usage. # Deviations from EthereumJ ### Code: - replaced Spring Framework Dependency Injection with Dagger 2 DI; - replaced org.springframework.util.FileSystemUtils with org.apache.commons.io.FileUtils; - replaced some worldManager injections with specific item injections from worldManager which were used; - replaced org.springframework.util.StringUtils.isEmpty with String.isEmpty(); - replaced @PostConstruct annotation with explicit method invocation in contructor; - replaced java.nio.file.Files with org.apache.commons.io.FileUtils; - replaced javax.xml.bind.DatatypeConverter.hexStringToByteArray with custom implementation; - commented javax.swing references in Utils.java; ### Gradle: - changed from java build to android build; - updated netty-all from 4.0.23 to 4.0.28; - disabled org.antlr:antlr4-runtime:4.5 ( use 4.0 from com.yuvalshavit:antlr-denter:1.1 ); - replaced org.slf4j:slf4j-api:1.7.7 with org.slf4j:slf4j-android:1.7.12 - removed org.javassist:javassist:3.15.0-GA; - removed log4j:log4j:${log4jVersion}; - removed org.hibernate:hibernate-core:${hibernateVersion}; - removed org.hibernate:hibernate-entitymanager:${hibernateVersion}; - removed commons-dbcp:commons-dbcp:1.4; - removed redis.clients:jedis:2.6.0; - removed org.slf4j:slf4j-log4j12:${slf4jVersion}; - removed log4j:apache-log4j-extras:${log4jVersion}; # Todo - Android-specific BlockStore Implementation - Unit Tests This is a work in progress. # Gotchas Old devices will fail to auth in time and will be rejected by peers, please use modern devices. # Building from source - Clone this repository and run (make sure clean from previous builds) `./gradlew build` - Install onto Android Device `adb install -r app/build/outputs/apk/app-debug.apk` # License EthereumJ is released under the [MIT license](LICENSE).
