前提：
android6.0以上 并且tragetVersion >22的时候需要主动去做权限管理

基于RxPermission1.0 & RxJava 1.0
RxPermission 1.0: https://github.com/tbruyelle/RxPermissions
rxjava 1.0 :https://github.com/ReactiveX/RxJava/tree/1.x
两个都必须要导入，否则找不到类。

package com.zy.demo;

import android.Manifest;
import android.app.Activity;
import android.util.Log;

import com.tbruyelle.rxpermissions.Permission;
import com.tbruyelle.rxpermissions.RxPermissions;

import rx.functions.Action1;
