2018年11月12日23:38:36 后续会继续更新钱包转账，查询等功能

1.引用库

web3j:
implementation 'org.web3j:core:3.3.1-android'
bitcoinj: 
implementation 'org.bitcoinj:bitcoinj-core:0.14.7'

我的gradle文件如下：

    apply plugin: 'com.android.application'
    android {
        compileSdkVersion 27
        defaultConfig {
            applicationId "com.lv.wallet"
            minSdkVersion 19
            targetSdkVersion 27
            versionCode 1
            versionName "1.0"
            testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
            multiDexEnabled true
            vectorDrawables.useSupportLibrary = true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            buildConfigField "String", "BASE_URL", "\"http://api.openweathermap.org/data/2.5/\""
            buildConfigField "String", "API_KEY", "\"435e9075f348868c2714fe7c6895efa5\""
        }
        debug {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            buildConfigField "String", "BASE_URL", "\"http://api.openweathermap.org/data/2.5/\""
            buildConfigField "String", "API_KEY", "\"xxxx\""
        }
    }
    compileOptions {
        targetCompatibility 1.8
        sourceCompatibility 1.8
    }
}
dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    //web3j lib
    implementation 'org.web3j:core:3.3.1-android'
    implementation 'org.bitcoinj:bitcoinj-core:0.14.7'
    //用于生成助记词
    implementation 'io.github.novacrypto:BIP39:0.1.9'
    implementation 'com.google.code.gson:gson:2.8.5'
}
