Android项目架构搭建

引入依赖库

1	2	3	4	5	6
retrofit	okhttp	okio	RxJava	RxAndroid

参考文档

1. Linux命令大全
2. Android Gradle Plugin 3.0 implementation、api、compile区别
3. 给 Android 开发者的 RxJava 详解
4. RxJava + Retrofit完成网络请求

一、创建项目

1. 新建SilenceCoder项目，创建时勾选添加Kotlin支持，以便后续扩展。
2. 创建BaseFeature Library便于以后结构改造成Instant App。

二、配置权限

1. 网络权限

      <uses-permission android:name="android.permission.INTERNET"/>
   

三、 在BaseFeature中引入Retrofit 2.x 网络库

1. 添加依赖

    implementation 'com.squareup.retrofit2:retrofit:2.3.0'
   

2. Retrofit 混淆配置。
   依赖关系：Retrofit ---->okhttp---->okio。所以相应的混淆都应该添加

    # Platform calls Class.forName on types which do not exist on Android to determine platform.
    -dontnote retrofit2.Platform
    # Platform used when running on Java 8 VMs. Will not be used at runtime.
    -dontwarn retrofit2.Platform$Java8
    # Retain generic type information for use by reflection by converters and adapters.
    -keepattributes Signature
    # Retain declared checked exceptions for use by a Proxy instance.
    -keepattributes Exceptions
   

3. okhttp 混淆配置

    -dontwarn okhttp3.**
    -dontwarn okio.**
    -dontwarn javax.annotation.**
    -dontwarn org.conscrypt.**
    # A resource is loaded with a relative path so the package of this class must be preserved.
    -keepnames class okhttp3.internal.publicsuffix.PublicSuffixDatabase
   

4. Okio混淆配置

    -dontwarn okio.**
   

四、在BaseFeature中引入Retrofit Gson Converter，参考retrofit中Converters章节，支持如下Converters：

• Gson: com.squareup.retrofit2:converter-gson
• Jackson: com.squareup.retrofit2:converter-jackson
• Moshi: com.squareup.retrofit2:converter-moshi
• Protobuf: com.squareup.retrofit2:converter-protobuf
• Wire: com.squareup.retrofit2:converter-wire
• Simple XML: com.squareup.retrofit2:converter-simplexml
• Scalars (primitives, boxed, and String): com.squareup.retrofit2:converter-scalars

五、在BaseFeature中引入RxJava 2.x.y库

1. 添加依赖

   implementation "io.reactivex.rxjava2:rxjava:2.x.y"
   

六、在BaseFeature中引入RxAndroid库

1. 添加依赖

    implementation 'io.reactivex.rxjava2:rxandroid:2.0.2'
