Android App 升级执行流程
1、获取本地版本号
2、请求服务器获取服务器版本号
3、本地版本和服务器版本不一致提示升级,弹窗提示用户是否更新
4、用户确定升级,调用文件传输方法下载 apk 文件
5、监听下载进度
6、下载完成打开 Apk 进行安装
注意:在 ios 中没法直接下载安装,如果版本不一致直接跳转到 Ios 应用对应的应用市场就即可。
自动升级 APP 需要的插件

App Version |
cordova-plugin-app-version |
https://ionicframework.com/docs/native/app-version/ |
File Opener |
cordova-plugin-file-opener2 |
https://ionicframework.com/docs/native/file-opener/ |
File Transfer |
cordova-plugin-file-transfer |
https://ionicframework.com/docs/native/file-transfer/ |
File |
cordova-plugin-file |
https://ionicframework.com/docs/native/file/ |
在 app.module.ts 引入注入
import { FileOpener } from '@ionic-native/file-opener/ngx'; import { FileTransfer } from '@ionic-native/file-transfer/ngx'; import { AppVersion } from '@ionic-native/app-version/ngx'; import { File } from '@ionic-native/file/ngx';
providers: [ FileOpener, FileTransfer, AppVersion, File, ... { provide: RouteReuseStrategy, useClass: IonicRouteStrategy } ]
在需要监听更新下载的页面引入、注入
import { FileOpener } from '@ionic-native/file-opener/ngx'; import { FileTransfer,FileTransferObject } from '@ionic-native/file-transfer/ngx'; import { AppVersion } from '@ionic-native/app-version/ngx'; import { File } from '@ionic-native/file/ngx'; import { AlertController } from '@ionic/angular';
constructor(private file: File,private transfer:FileTransfer,private appVersion: AppVersion,private fileOpener: FileOpener,public alertController: AlertController) { }
4、获取版本号
this.appVersion.getVersionNumber().then((value:any) => { console.log(value) }).catch(err => { console.log('getVersionNumber:' + err); });
5、获取当前的 apk 安装目录
this.file.dataDirectory
const targetUrl = 'http://127.0.0.1:8080/test.apk'; const fileTransfer: FileTransferObject = this.transfer.create(); fileTransfer.download(targetUrl, this.file.dataDirectory + 'test.apk').then((entry) => { }, (error) => { alert(JSON.stringify(error)); });
6、下载文件,监听下载进度
onst fileTransfer: FileTransferObject = this.transfer.create(); fileTransfer.download(url, this.file.dataDirectory + test.apk'). then((entry) => { alert('download complete: ' + entry.toURL()); }, (error) => { alert(JSON.stringify(error));});
进度:
var oProgressNum=document.getElementById('num'); fileTransfer.onProgress((event: ProgressEvent) => { let num =Math.ceil(event.loaded/event.total * 100); if (num === 100) { oProgressNum.innerHTML='下载完成'; } else { oProgressNum.innerHTML='下载进度:' + num + '%'; } });
7、打开安装文件
this.fileOpener.open(entry.toURL(), 'application/vnd.android.package-archive') .then(() => { console.log('File is opened') }) .catch(e => { console.log('Error openening file', e) });
demo:
import { Component } from '@angular/core'; import { FileOpener } from '@ionic-native/file-opener/ngx'; import { FileTransfer, FileTransferObject } from '@ionic-native/file-transfer/ngx'; import { AppVersion } from '@ionic-native/app-version/ngx'; import { File } from '@ionic-native/file/ngx'; import { AlertController } from '@ionic/angular'; @Component({ selector: 'app-tab1', templateUrl: 'tab1.page.html', styleUrls: ['tab1.page.scss'] }) export class Tab1Page { constructor(private file: File, private transfer: FileTransfer, private appVersion: AppVersion, private fileOpener: FileOpener, public alertController: AlertController) { } //设备加载完成再去调用硬件 ngAfterContentInit(): void { //Called after ngOnInit when the component's or directive's content has been initialized. //Add 'implements AfterContentInit' to the class. this.isUpdate(); } isUpdate() { // 1、获取当前应用的版本号 this.appVersion.getVersionNumber().then((value: any) => { console.log(value) //2、请求服务器接口获取服务器的版本号 this.showAlert(); }).catch(err => { console.log('getVersionNumber:' + err); }); } async showAlert() { //3.弹窗提示用户是否更新 const alert = await this.alertController.create({ header: '升级!', message: '发现新版本,是否立即升级?', buttons: [ { text: '取消', role: 'cancel', cssClass: 'secondary', handler: (blah) => { } }, { text: '确认', handler: () => { //4.下载apk this.downloadApp(); } } ] }); await alert.present(); } downloadApp() { //4.下载apk const targetUrl = 'http://127.0.0.1:8080/test.apk'; const fileTransfer: FileTransferObject = this.transfer.create(); console.log(this.file.dataDirectory); //获取当前应用的安装(home)目录 1、应用包名称要一致 2、升级的包的版本号要大于当前应用的版本号 3、签名要一致 4、sdk 要安装 fileTransfer.download(targetUrl, this.file.dataDirectory + 'aaa.apk').then((entry) => { //6、下载完成调用打开应用 this.fileOpener.open(entry.toURL(), 'application/vnd.android.package-archive') .then(() => { console.log('File is opened') }) .catch(e => { console.log('Error openening file', e) }); }, (error) => { alert(JSON.stringify(error)); }); //5、获取下载进度 var oProgressNum = document.getElementById('progressnum'); fileTransfer.onProgress((event) => { let num = Math.ceil(event.loaded / event.total * 100); //转化成1-100的进度 if (num === 100) { oProgressNum.innerHTML = '下载完成'; } else { oProgressNum.innerHTML = '下载进度:' + num + '%'; } }); } }
效果:
