Android7.0版本升级安装

:running:BGAUpdate-Android:running: ============ ## 功能介绍 - [x] 适配 Android 8.+ 系统 - [x] 检测新版 apk 文件是否已经下载过 - [x] RxJava1.x + Retrofit2.x 下载新版 apk 文件 - [x] RxBus 监听下载进度 - [x] 安装 apk 文件 - [x] 删除之前升级时下载的老的 apk 文件 ## TODO - [x] 支持 RxJava2.x - [x] MD5 校验 ## 效果图与示例 apk  [点击下载 BGAUpdateDemo.apk](http://fir.im/BGAUpdateDemo) 或扫描下面的二维码安装  ## 使用 ### 1.添加 Gradle 依赖 [](https://bintray.com/bingoogolapple/maven/bga-update/_latestVersion) bga-update 后面的「latestVersion」指的是左边这个 Download 徽章后面的「数字」，请自行替换。 ```groovy dependencies { compile 'cn.bingoogolapple:bga-update:latestVersion@aar' // 换成己工程里依赖的 rxjava 和 retrofit 版本 compile 'io.reactivex:rxjava:1.3.2' compile 'io.reactivex:rxandroid:1.2.1' compile 'com.squareup.retrofit2:retrofit:2.3.0' compile 'com.squareup.retrofit2:converter-gson:2.3.0' compile 'com.squareup.retrofit2:adapter-rxjava:2.3.0' } ``` ### 2.在 Activity 的 onCreate 方法中监听下载进度。demo 里引用了 rxlifecycle 这个库来防止 Activity 内存泄漏 ```java BGAUpgradeUtil.getDownloadProgressEventObservable() .compose(this.<BGADownloadProgressEvent>bindToLifecycle()) .subscribe(new Action1<BGADownloadProgressEvent>() { @Override public void call(BGADownloadProgressEvent downloadProgressEvent) { if (mDownloadingDialog != null && mDownloadingDialog.isShowing() && downloadProgressEvent.isNotDownloadFinished()) { mDownloadingDialog.setProgress(downloadProgressEvent.getProgress(), downloadProgressEvent.getTotal()); } } }); ``` ### 3.下载新版 apk 文件。注意先申请 WRITE_EXTERNAL_STORAGE 权限 ```java @AfterPermissionGranted(RC_PERMISSION_DOWNLOAD) public void downloadApkFile() { String[] perms = {Manifest.permission.WRITE_EXTERNAL_STORAGE}; if (EasyPermissions.hasPermissions(this, perms)) { // 如果新版 apk 文件已经下载过了，直接 return，此时不需要开发者调用安装 apk 文件的方法，在 isApkFileDownloaded 里已经调用了安装」 if (BGAUpgradeUtil.isApkFileDownloaded(mNewVersion)) { return; } // 下载新版 apk 文件 BGAUpgradeUtil.downloadApkFile(mApkUrl, mNewVersion) .subscribe(new Subscriber<File>() { @Override public void onStart() { showDownloadingDialog(); } @Override public void onCompleted() { dismissDownloadingDialog(); } @Override public void onError(Throwable e) { dismissDownloadingDialog(); } @Override public void onNext(File apkFile) { if (apkFile != null) { BGAUpgradeUtil.installApk(apkFile); } } }); } else { EasyPermissions.requestPermissions(this, "使用 BGAUpdateDemo 需要授权读写外部存储权限!", RC_PERMISSION_DOWNLOAD, perms); } } ``` ### 4.下次进入应用时删除之前升级时下载的老的 apk 文件 ``` BGAUpgradeUtil.deleteOldApk(); ``` ## 代码是最好的老师，更多详细用法请查看 [demo](https://github.com/bingoogolapple/BGAUpdate-Android/tree/master/demo):feet: ## 贡献者 * [bingoogolapple](https://github.com/bingoogolapple) * [chenfei0928](https://github.com/chenfei0928) * [HYVincent](https://github.com/HYVincent) ## 关于我 | 新浪微博 | 个人主页 | 邮箱 | BGA系列开源库QQ群 | ------------ | ------------- | ------------ | ------------ | | <a href="http://weibo.com/bingoogol" target="_blank">bingoogolapple</a> | <a href="http://www.bingoogolapple.cn" target="_blank">bingoogolapple.cn</a> | <a href="mailto:bingoogolapple@gmail.com" target="_blank">bingoogolapple@gmail.com</a> |  | ## 打赏支持 如果您觉得 BGA 系列开源库帮你节省了大量的开发时间，请扫描下方的二维码随意打赏，要是能打赏个 10.24 :monkey_face:就太:thumbsup:了。您的支持将鼓励我继续创作:octocat: 如果您目前正打算购买通往墙外的梯子，可以使用我的邀请码「YFQ9Q3B」购买 [Lantern](https://github.com/getlantern/forum)，双方都赠送三个月的专业版使用时间:beers: <p align="center"> <img src="http://7xk9dj.com1.z0.glb.clouddn.com/bga_pay.png" width="450"> </p> ## License Copyright 2015 bingoogolapple Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.
