AdroidStudioapp远程升级

手机APP开发完了，远程升级自动更新版本必不可少，不然每次更新版本就要重新安装，那就不合理了。刚开始感觉还没啥头绪，不会了

就问百度，复制粘贴修修改改就搞定了，直接上代码：

首先要在AndroidManifest添加版本号。

远程升级类

package ;

import adManager;

import astReceiver;

import t;

import ;

import Filter;

import ;

import ;

import ;

import nment;

import ;

import peMap;

import ;

import esApi;

import ovider;

import ;

import ption;

public class AppUpdataManger {

private String tag = "AppUpdataManger";

private DownloadManager downloadManager;

private Context mContext;

private long mTaskId;

private String downloadPath;

private String versionName;

public AppUpdataManger(Context context) {

xt = context;

}

//广播接收者，接收下载状态

private BroadcastReceiver receiver = new BroadcastReceiver() {

@Override

public void onReceive(Context context, Intent intent) {

checkDownloadStatus();//检查下载状态

}

};

@RequiresApi(api = N_OMB)

public void downloadAPK(String versionUrl, String versionName) {

nName = versionName;

Log.e("下载", versionUrl + versionName);

//将下载请求加入下载队列

downloadManager = (DownloadManager) temService(AD_SERVICE);

//创建下载任务

t request = new t((versionUrl));

owedOverRoaming(false);//漫游网络是否可以下载

//设置文件类型，可以在下载结束后自动打开该文件

MimeTypeMap mimeTypeMap = gleton();

String mimeString = eTypeFromExtension(eExtensionFromUrl(versionUrl));

eType(mimeString);//加入任务队列

//在通知栏显示，默认就是显示的

ificationVisibility(LITY_VISIBLE);

//设置通知栏标题

le("Download");

cription("");

owedOverRoaming(false);

ibleInDownloadsUi(true);

//设置下载的路径

File file = new File(ernalFilesDir(ORY_DOWNLOADS), versionName);

tinationUri(le(file));

downloadPath = olutePath();

//加入下载列后会给该任务返回一个long型的id,

//通过该id可以取消任务，重启任务等等 mTaskId = e(request);

//注册广播接收，监听下载状态

erReceiver(receiver, new IntentFilter(_DOWNLOAD_COMPLETE));

}

//检查下载状态

private void checkDownloadStatus() {

query = new ();

terById(mTaskId);//赛选下载任务，传入任务ID,可变参数

Cursor cursor = (query);

if (First()) {

int status = (umnIndex(_STATUS));

switch (status) {

case _PAUSED:

//下载暂停

Log.d(tag, "下载暂停");

break;

case _PENDING:

//下载延迟

Log.d(tag, "下载延迟");

break;

case _RUNNING:

//正在下载

Log.d(tag, "正在下载");

break;

case _SUCCESSFUL:

xt(mContext, "下载完成", _LONG).show();

//打开文件进行安装

installAPK();

break;

case _FAILED:

//下载失败

Log.d(tag, "下载失败");

xt(mContext, "更新失败", _LONG).show();

break;

}

}

();

}

//下载到本地后执行安装根据获得的id进行安装

protected void installAPK() {

setPermission(downloadPath);

Intent intent = new Intent(_VIEW);

// 由于没有在Activity环境下启动Activity,设置下面的标签

gs(_ACTIVITY_NEW_TASK);

//Android 7.0以上要使用FileProvider

if (_INT >= 24) {

File file = (new File(downloadPath));

//参数1 上下文, 参数2 Provider主机地址 和配置文件中保持一致 参数3 共享的文件

Uri apkUri = ForFile(mContext, "ovider", file);

//添加这一句表示对目标应用临时授权该Uri所代表的文件

gs(_GRANT_READ_URI_PERMISSION);

aAndType(apkUri, "application/e-archive");

} else {

aAndType(le(new File(ORY_DOWNLOADS, versionName)), "application/e-archive");

}

ctivity(intent);

}

//修改文件权限

private void setPermission(String absolutePath) {

String command = "chmod " + "777" + " " + absolutePath;

Runtime runtime = time();

try {

(command);

} catch (IOException e) {

tackTrace();

}

}

}

判断远程是否需要升级是根据版本号来判断的，所以你要在数据库要有一个版本列表的。每次登录都要获取数据库中最新版本和本地版本作

比较。较之低的话，启用远程升级。
