问题 I recently read about that Google is using File-by-File Patching and another one algorithm BsDiff - Delta update which patches apk files and gives only update sized apk to download from Play Store. I went through below blogs and links: 1) https://android-developers.googleblog.com/2016/12/saving-data-reducing-the-size-of-app-updates-by-65-percent.html 2) https://github.com/andrewhayden/archive-patcher/blob/master/README.md for "File-by-File Patching" 3) https://android-developers.googleblog

问题 I am using libraries provided by the android sdk for apk expansion file to download the obb file, however I am not sure how to extract these files to the correct directory or if it is even possible? The .obb file downloads correctly, and I can read the entire directory, however once I try and use any of the resources inside the zipped assets folder it doesnt find it.

adb 安装与使用(一)

阅读更多关于 adb 安装与使用(一)

一、ADB简介 1. 什么是adb？　　adb（Android Debug Bridage）是Android sdk的一个工具；　　adb 是用来连接安卓手机和PC端的桥梁，要有adb作为二者之间的维系，才能让用户在电脑上对手机进行全面的操作。　　Android 的初衷是用adb这样的一个工具来协助开发人员在开发和拷贝Android 应用的过程中更好的调试apk ，因此adb具有安装和卸载apk，拷贝推送文件，查看设备硬件信息，查看应用程序占用资源，在设备执行shell命令等功能！ 2.adb的组成　　客户端client：运行在你的电脑上，你可以通过adb命令来调起一个客户端。其他的安卓工具例如：ADT插件、DDMS都可以创建出一个客户端　　服务器server：运行在你电脑上的后台，负责管理client和daemon进行通信。　　守护进程 daemon：运行在模拟器或者Android 设备的后台二、adb的安装 1.下载解压：adt-bundle-windows-x86_64-20140702（自行百度下载） 2. 配置环境变量到path 　　D:\appium\adt-bundle-windows-x86_64-20140702\sdk\platform-tools; 　　D:\appium\adt-bundle-windows-x86_64-20140702

作为一个Android开发，现在的你已经开发多少年了？你的代码质量有没有随着经验的增加而提高？没有的话就需要反思了。现在来分享一个有六年经验Android开发，都学到了什么？一，学习能力想要成长，学习能力尤为重要我们一直有句老话，学如逆水行舟，不进则退。就像我们Android进阶，需要学习的高级内容比较多 1）Java语言进阶与Android相关技术内核像泛型，多线程，反射，JVM，Java IO，注解，序列化等 2）App开发框架知识体系（app亦对象） Android 2013~2016年的技术，大家网上Copy代码习惯了对这块经常“使用”的代码熟悉而又陌生：熟悉的是几乎天天在和它们打交道，天天在复制这些代码；陌生的是虽然天天和这些代码打交道，从未深入研究过这些代码的原理，代码深处的内涵。我们需要从新的角度去分析这些知识点，深入研究他们，要学习源码，模仿源码，然后再hook源码，这样才能说自己懂这块的知识。这些都是做Android开发，做高级工程师的基础。 3）360° Android app全方位性能调优书写高性能代码，再调优 4）Android前沿技术比如热升级，热修复，App Instant，强制更新，组件化路由架构Arouter，RxJava，IOC架构方法，Hook技术等这些技术你不能只会用，你需要知道他的原理 5）NDK 模块开发 NDK

I am using macOSX, and trying to extract all the files in a APK file, I've extracted it with zip and unzip. Used dex2jar to extract classes.dex to jar file and decompiled it. Now when I am in my last step, using APKtool to decode the apk file, however, it shows "-bash: apktool: command not found " eventhough I
