1. 添加依赖

dependencies {
//   RxPermissions 的使用方法详解
    implementation 'com.github.tbruyelle:rxpermissions:0.10.2'
    implementation 'io.reactivex.rxjava2:rxandroid:2.1.0'
    implementation 'io.reactivex.rxjava2:rxjava:2.2.4'
}

项目根目录的build.gradle下添加 maven { url 'https://jitpack.io' }

allprojects {
    repositories {
        maven { url 'https://jitpack.io' }
               maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/'}

        jcenter()
