2018版本更新了解一下
版本更新迫使我们技术进步，我自己写了一般可能略粗糙，先记录一下，网络框架使用的是xutils3
调用：
checkUpdateUtils.checkUpdate(LoginActivity.this,"appname");
工具类：
import android.annotation.SuppressLint;
import android.app.ProgressDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.content.Intent;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;

import android.support.v7.app.AlertDialog;

manifest中添加provider（位置在application中，与activity同等级）
在res下创建 xml文件夹创建filepaths.xml(路劲和起名和manifest中resource一致就好)
