Hi, In this article, we'll discuss five Android developer interview questions from our website. We go for each question into advice and how to answer them along with an answer example. Afterwards, if you found this video helpful, please like and share. Let's get started. Question number one, how would you describe Android to someone without a technical background? Interviewers will ask you this question for several reasons. The first is to begin the conversation and learn more about your background. How you describe Android will indicate your technical knowledge of this programming environment. They are also interested in your communication skills, being able to discuss a technical topic with somebody without a technical background, demonstrates your ability to collaborate across the organization. This is important to any software development role. Here's our answer example. Android is an open source operating system based on Linux and developed by Andy Rubin. It is used primarily for devices such as cell phones and tablets. The Android operating system competes directly with apple iOS. In this market space. Applications developed by Android will run on a wide variety of platforms with little to no additional format.

大家好，在本节中，我们将讨论来自网站的五个Android开发人员面试问题。我们对每个问题都提出了建议，以及如何回答这些问题，并给出了答案示例。之后，如果你觉得这个视频有帮助，请点赞并分享。我们开始吧。第一个问题，你会如何向没有技术背景的人描述Android？面试官问你这个问题有几个原因。首先是开始谈话，更多地了解你的背景。你如何描述Android将表明你对这个编程环境的技术知识。他们还对你的沟通技巧感兴趣，能够与没有技术背景的人讨论技术话题，证明你有能力在整个组织内进行协作。这对任何软件开发角色都很重要。下面是我们的答案示例。Android是基于Linux的开源操作系统，由Andy Rubin开发。它主要用于手机和平板电脑等设备。安卓操作系统直接与苹果IOS竞争。在这个市场空间里。Android开发的应用程序可以在各种平台上运行，几乎不需要额外的格式。

Question number two, what are the earliest and latest versions of Android work with? Like any other operating system? Android has evolved through many different iterations. Each version is designated by number that can contain up to three decimal places. Each version is also given a nickname, such as cupcake, donut, marshmallow, or Oreo. Interviewers will ask you about your experience, working with the different versions of android to, understand how long you've been programming in this environment, how familiar you are with each version, knowing about the pedigree and evolution of the operating system, but also increase your programming skills and make you more valuable to organization.

第二个问题，Android最早和最新的版本是什么？像其他操作系统一样？Android经历了许多不同的迭代。每个版本都由最多可包含三个小数位的数字指定。每个版本都有一个昵称，如纸杯蛋糕、甜甜圈、棉花糖或奥利奥。面试官会询问你的经验，使用不同版本的Android，了解你在这个环境中编程的时间，你对每个版本的熟悉程度，了解操作系统的诞生和演化，而且还可以提高您的编程技能，使您对组织更有价值。

I began working in the Android operating system as early as 2008 with version 1 . 0, which didn't have to name. I continue working on versions to through 11, which is the latest evolution of the Android operating system. Nick names for Android, such as gingerbread honeycomb and jelly bean, or typical for the early versions. However, the nicknames were dropped affected with Android 10 . 0 released in 2019. Each subsequent version of the Android operating system added additional features, making the operating system more effective and easier to work.

早在2008年，我就开始使用Android操作系统 1.0，当时还没命名。我继续开发到11的版本，这是Android操作系统的最新版本。关于Android的昵称，如姜饼蜂巢（Gingerbread Honeycomb）和果冻豆（Jelly Bean），或者早期版本的典型版本。然而，这些昵称受到了Android 10.0的影响，于2019年发布。Android操作系统的每个后续版本都添加了额外的功能，使操作系统更有效、更易于工作。

With question number three, what steps can you take to avoid? Application is not responding errors when working in Android, in nar or application not responding, dialogue box will appear whenever an application is not responding. There are several reasons that this may occur and has an Android developer. You should be familiar with these and how to avoid or break them a and r or an applications not responding. Dialogue indicates that there is a problem with the program. This can occur when there is no response after he designated time. If a broadcast receiver fills the function within approximately 10 seconds, we still avoid this include ensuring that application uses separate threads to perform operations, which makes you the wait time limits or using intent service to take the pressure off of user interface threads.

对于第三个问题，你可以采取哪些措施来避免？在Android、ANR或应用程序无响应中工作时，应用程序无响应错误，只要应用程序没有响应，就会出现对话框。有几个原因可能会发生这种情况，并有一个Android开发人员。您应该熟悉这些，以及如何避免或破坏它们 ANR或应用程序不响应。对话表示程序有问题。这可能发生在指定时间后没有响应的情况下。如果广播接收器在大约10秒内填满函数，我们仍然可以避免这种情况，包括确保应用程序使用单独的线程来执行操作，这会使您受到等待时间限制，或者使用意图服务来减轻用户界面线程的压力。

Question number four, if an application you developed and Android frequently crashes, what steps can you take to identify and fix the issue? It is exceedingly rare that application will crash once properly developed, tested, and implemented. However, certain circumstances will cause applications to crash. As an Android developer, you should be aware of these and program. You go to avoid them. If an application crashes, well in production, you should be able to provide advice to the support team or end users to ask how to fix it. The interviewer will ask you this question to ensure that you are aware of this and have a portfolio of solutions to address application issues. My applications rarely crash.

第四个问题，如果您开发的应用程序和Android经常崩溃，您可以采取哪些步骤来识别和修复该问题？一旦正确地开发、测试和实现，应用程序崩溃的情况是极其罕见的。但是，某些情况会导致应用程序崩溃。作为一名Android开发人员，您应该了解这些和程序。你去避开他们。如果应用程序在生产中崩溃，您应该能够向支持团队或最终用户提供建议，询问如何修复它。面试官会问你这个问题，以确保你意识到这一点，并有一套解决方案来解决申请问题。我的应用程序很少崩溃。

However, I take immediate steps to, resolve the issue when it does occur. First, I determine the device on which the application is running and whether it is compatible with the code that I have developed. Android applications are compatible with most devices. There are few outliers that may cause problems. Another issue is memory. If the application is competing for the systems, memory, CPU, cycles, or other shared resources, and they get hung up or crash, shutting down other applications or clearing applications, cashi memory typically resolves.

然而，当问题发生时，我会立即采取措施解决问题。首先，我要确定运行应用程序的设备，以及它是否与我开发的代码兼容。Android应用程序与大多数设备兼容。可能导致问题的离群值很少。另一个问题是内存。如果应用程序正在竞争系统、内存、CPU、周期或其他共享资源，并且它们挂起或崩溃，关闭其他应用程序或清除应用程序，则Cashi内存通常会解决问题。

Question number five, please describe some of the main features of the Android architecture being able to describe the main features of the Android architect will demonstrate your competency in this area and your knowledge of the operating system. You can anticipate many questions similar to this one, but the interviewer will use to probe your experience and knowledge, like many operating systems.

第五个问题，请描述Android架构的一些主要功能。能够描述Android架构师的主要功能将证明您在该领域的能力以及您对操作系统的了解。你可以预料到许多类似的问题，但面试官会用来探究你的经验和知识，就像许多操作系统一样。

The Android architecture is composed of various layers known as the Android stack. This consists of the operating system, nowhere and applications. The five layers include Linux, colonel, libraries of open source code, Android run time, including the dialect, virtual and Android run time. Enjoy framework, which contains the AP is in UI and the applications, which are what the users are most familiar with. Together, the stack enables applications written for the Android environment to run on a variety of different mobile platforms, including phones and tablets.

Android架构由称为Android堆栈的各种层组成。这包括操作系统，无处和应用程序。这五层包括Linux、Colonel、开源代码库、Android运行时（包括方言）、虚拟和Android运行时。Enjoy框架，它包含用户界面中的AP和应用程序，这是用户最熟悉的。总之，该堆栈使为Android环境编写的应用程序能够在各种不同的移动平台上运行，包括手机和平板电脑。
