React Native Android 下载 apk并安装
实现通过apk链接，下载最新apk并安装功能。
代码如下
DownloadApk

import android.app.DownloadManager;

public static String description;
DownloadManager downManager;
Activity myActivity;
final static String log = "DownloadApk";
public DownloadApk(ReactApplicationContext reactContext) {
super(reactContext);
}
@Override
public String getName() {
return "DownloadApk";
}
@ReactMethod
public void downloading(String url, String title, String description) {
DownloadApk.description = description;
myActivity = getCurrentActivity();
downManager = (DownloadManager)myActivity.getSystemService(Context.DOWNLOAD_SERVICE);
Uri uri = Uri.parse(url);
Request request = new Request(uri);
// 设置允许使用的网络类型，这里是移动网络和wifi都可以
request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_MOBILE | DownloadManager.Request.NETWORK_WIFI);
//设置通知栏标题
request.setNotificationVisibility(Request.VISIBILITY_VISIBLE);
request.setMimeType("application/vnd.android.package-archive");
if (title == null || title.trim().equals("")) {
title = "app 名字"; //这里可以改为自己app的名字
}
request.setTitle(title);
if (description == null || "".equals(description)) {
description = "目标apk正在下载";
}
request.setDescription(description);
request.setAllowedOverRoaming(false);
// 设置文件存放目录
request.setDestinationInExternalFilesDir(myActivity, Environment.DIRECTORY_DOWNLOADS, description);

}
}
