Hi there, 嘿，你好

Welcome to the ” Android App Development with 7 Real Android Apps and Java ” course.
欢迎来到“ 使用 7 个真正的 Android Apps 和 Java 进行 Android 应用程序开发 ”课程。
Android App Development with Android Studio & Java, boost your android development skills with 7 different Android Apps
使用 Android Studio 和 Java 进行 Android 应用程序开发，使用 7 种不同的 Android 应用程序提高您的 Android 开发技能

Due to its open-source nature, working with the Android platform necessitates constantly learning about the Android platform. My android development course on Udemy keeps you ahead of this learning curve, with hands-on lectures on Android operating systems and more.
由于其开源性质，使用 Android 平台需要不断了解 Android 平台。我在 Udemy 上的 android 开发课程让您在这个学习曲线上处于领先地位，其中包含有关 Android 操作系统等的实践讲座。
The Android platform is increasingly popular with developers and a dominant force in the global smartphone market. As more businesses develop mobile apps for customer engagement, Android development skills are likely to stay in high demand.
Android平台越来越受到开发人员的欢迎，并成为全球智能手机市场的主导力量。随着越来越多的企业开发用于客户参与的移动应用程序，Android 开发技能的需求可能会保持很高。

I really like the approach of this course. It first teaches you Java which is highly important for designing apps in Android. Next, the instructor focuses on the Android SDK to teach you how to build beautiful applications for smartphones. As the course title indicates, it is the complete guide.
我真的很喜欢这门课程的方法。它首先教你 Java，这对于在 Android 中设计应用程序非常重要。接下来，讲师将重点介绍Android SDK，教您如何为智能手机构建漂亮的应用程序。正如课程标题所示，它是完整的指南。

Android development is a software creation process that focuses on applications, better known as apps, that are compatible with devices running the Android operating system (OS). Because Android is an open-source project, developers have easy access to the Android software development kit (SDK). Many use this kit in conjunction with Kotlin, Java, and C++ programming languages to make their apps. The Android SDK tools compile your code along with any data and resource files into an APK, or Android package, which is an archive file that uses an .apk suffix. One APK file contains all Android app contents used by devices to install your app. When the app is complete and ready for release, Android developers can upload their apps to the Google Play Store for users to download.
Android 开发是一个软件创建过程，专注于与运行 Android 操作系统 （OS） 的设备兼容的应用程序（更广为人知的应用程序）。由于 Android 是一个开源项目，因此开发人员可以轻松访问 Android 软件开发工具包 （SDK）。许多人将此工具包与 Kotlin、Java 和 C++ 编程语言结合使用来制作他们的应用程序。Android SDK 工具将您的代码以及任何数据和资源文件编译到 APK 或 Android 包中，后者是使用 .apk 后缀的存档文件。一个 APK 文件包含设备用于安装应用的所有 Android 应用内容。当应用完成并准备好发布时，Android 开发者可以将其应用上传到 Google Play 商店供用户下载。

Chances are, you’ve heard of Android many times. You may even have an Android smartphone, tablet, watch, or TV. But what is Android? Android is a mobile operating system (OS) that was designed and developed by Google. The Android OS is Linux kernel-based. So, what’s “Linux kernel,” and why is that such an essential detail about Android Development?
很有可能，您已经多次听说过 Android。您甚至可能拥有 Android 智能手机、平板电脑、手表或电视。但什么是Android？Android 是由 Google 设计和开发的移动操作系统 （OS）。Android 操作系统基于 Linux 内核。那么，什么是“Linux 内核”，为什么它是 Android 开发的重要细节？

In a nutshell, Linux kernel is an OS, well, sort of — it’s partially an OS. More like a small part of an OS, but an important one. The Linux kernel is the layer responsible for interfacing with the device’s hardware and managing the device’s CPU and memory. The Android OS is Linux kernel-based because the Linux kernel allows for a more open and customizable OS, which is what Android promotes — any device manufacturer can take the Android OS and make it their own.
简而言之，Linux 内核是一个操作系统，嗯，在某种程度上——它部分是一个操作系统。更像是操作系统的一小部分，但却是一个重要的部分。Linux 内核是负责与设备硬件连接并管理设备 CPU 和内存的层。Android 操作系统是基于 Linux 内核的，因为 Linux 内核允许更开放和可定制的操作系统，这正是 Android 所提倡的——任何设备制造商都可以采用 Android 操作系统并使其成为自己的操作系统。

Imagine how bad it would be if, say, resources from application A read information from another application’s files and vice versa with no constraints — malicious, insecure interactions would take hold and bring the whole system to a halt.
想象一下，如果应用程序 A 的资源从另一个应用程序的文件中读取信息，反之亦然，而没有限制，那将是多么糟糕——恶意的、不安全的交互会占据主导地位并使整个系统停止运行。

The sharing of information (data) between applications is an essential part of building inter-connected applications, so the android OS requires developers to set permissions that users must grant to do certain things. For example, for an application to access the phone’s File System (internal files),the user must give access first. This means the app developer must let the user know, in advance, what the app they are installing wants to access. For example, when a user installs an android app that needs to access the photo gallery or the phone’s camera, the app will ask for permission to access the gallery or the camera. The app user has the power to either grant or deny permission. App permissions in Android ensure the user’s protection from malware and software viruses
应用程序之间的信息（数据）共享是构建互连应用程序的重要组成部分，因此 android 操作系统要求开发人员设置用户必须授予的权限才能执行某些操作。例如，要使应用程序访问电话的文件系统（内部文件），用户必须首先授予访问权限。这意味着应用开发者必须提前让用户知道他们正在安装的应用想要访问的内容。例如，当用户安装需要访问照片库或手机相机的 Android 应用时，该应用将请求访问图库或相机的权限。应用程序用户有权授予或拒绝权限。Android 中的应用权限可确保用户免受恶意软件和软件病毒的侵害

What are some of the important tools for Android Development?
Android 开发有哪些重要工具？
The tools you will use for Android development depend on how you would like to focus your career as an Android developer. If you plan on focusing on native Android app development, you should know one or more of three programming languages: Java, Kotlin, and C++. Java and Kotlin are popular with a number of organizations that build their app natively. C++ is the popular choice amongst developers who build high-performance games or plan on doing entry-level SDK work. Some employers seek out Android developers that can create multiple platforms at the same time using programming frameworks like Flutter or React Native. If you are working with Flutter, you will also need to know Dart. If you are working with React Native, you will most likely also need JavaScript programming knowledge.
您将用于 Android 开发的工具取决于您希望如何专注于您作为 Android 开发人员的职业生涯。如果您打算专注于原生 Android 应用程序开发，您应该了解三种编程语言中的一种或多种：Java、Kotlin 和 C++。Java 和 Kotlin 在许多原生构建应用程序的组织中很受欢迎。C++ 是构建高性能游戏或计划进行入门级 SDK 工作的开发人员的热门选择。一些雇主寻找可以使用 Flutter 或 React Native 等编程框架同时创建多个平台的 Android 开发人员。如果你正在使用 Flutter，你还需要了解 Dart。如果你正在使用 React Native，你很可能还需要 JavaScript 编程知识。
Is Android Development a good career?
Android 开发是个好职业吗？
With over 2.5 billion active Android users globally, Android development is a valuable skill that can help you enhance your career. Android development skills are in-demand around the world with various organizations across a broad range of industries. When these organizations build Android apps natively, the top three programming languages are typically Java, Kotlin, and C++. You can also look for a job in Android development that uses cross-platform solutions like Flutter or React Native. Whether you’re inspired to add a new language to your repertoire or prepare for an interview, you can find a ton of online resources on sites like OAK Academy to keep your Android skills well-rounded.
Android 在全球拥有超过 25 亿活跃的 Android 用户，因此 Android 开发是一项宝贵的技能，可以帮助您提升职业生涯。Android 开发技能在世界范围内受到各行各业各种组织的需求。当这些组织原生构建 Android 应用程序时，排名前三的编程语言通常是 Java、Kotlin 和 C++。您还可以在 Android 开发中寻找使用 Flutter 或 React Native 等跨平台解决方案的工作。无论你是想在曲目中加入一门新语言，还是准备面试，你都可以在OAK Academy等网站上找到大量的在线资源，让你的安卓技能得到全面提升。

Is Kotlin or Java better for Android Development?
Kotlin 还是 Java 更适合 Android 开发？
If you are building new Android apps, Kotlin is better suited because it is the recommended programming language for Android. If you are a first-time programmer, Kotlin android is also a better choice as it has safety features and concise syntax that will help you focus on learning core program fundamentals. You should note that in some cases, employers may seek out Android developers that have Java programming skills. For example, if you plan on joining an organization that already has an Android app, they may already be using Java. If they already have an app written in Java, it is unlikely they will want to redesign the app in a different language, such as android kotlin. Therefore, you should look at the job requirements to see if the job posting you are interested in lists Java as a required skill.
如果您正在构建新的 Android 应用程序，Kotlin 更适合，因为它是 Android 的推荐编程语言。如果您是初次编程，Kotlin android 也是一个更好的选择，因为它具有安全功能和简洁的语法，可以帮助您专注于学习核心程序基础知识。您应该注意，在某些情况下，雇主可能会寻找具有 Java 编程技能的 Android 开发人员。例如，如果您计划加入一个已经拥有 Android 应用的组织，则他们可能已经在使用 Java。如果他们已经有一个用 Java 编写的应用程序，他们不太可能想要用不同的语言（例如 android kotlin）重新设计应用程序。因此，您应该查看工作要求，看看您感兴趣的职位发布是否将 Java 列为必备技能。
