MVP框架+Dagger2实现简单注册

工程里加入config.gradle

ext {
    android = [
            compileSdkVersion: 27,
            applicationId    : "com.bwei.mvp1",
            minSdkVersion    : 15,
            targetSdkVersion : 27,
            versionCode      : 1,
            versionName      : "1.0"
    ]

    dependencies = [
            "appcompat-v7"     : "com.android.support:appcompat-v7:27.1.1",
            "constraint-layout": "com.android.support.constraint:constraint-layout:1.1.0",
            "retrofit2"        : "com.squareup.retrofit2:retrofit:2.4.0",
            "converter-gson"   : "com.squareup.retrofit2:converter-gson:2.4.0",
            "adapter-rxjava"  :  "com.squareup.retrofit2:adapter-rxjava2:2.4.0",
            "rxjava2"          : "io.reactivex.rxjava2:rxjava:2.1.13",
            "rxjava2:rxandroid": "io.reactivex.rxjava2:rxandroid:2.0.2",
            "dagger"           : "com.google.dagger:dagger:2.8",
            "dagger-compiler" : "com.google.dagger:dagger-compiler:2.7"

    ]
}

工程的build.gradle最上面加入  apply from: "config.gradle"

    app的build.gradle加入依赖,下面的从头到尾复制进去

apply plugin: 'com.android.application'
