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 formatting." 2) What are the earliest and latest versions of Android you have worked with? Answer Example: "I began working in the Android operating systems as early as 2008 with version 1.0, which didn't have a code name. I continued working on versions 2 through 11, which is the latest evolution of the Android operating system. Nicknames for Android such as Gingerbread, Honeycomb, and Jelly Bean were typical for the early versions. However, the nicknames were dropped effective with Android 10.0 released in 2019. Each subsequent version of the Android OS added additional features making the operating system more effective and easier to work with." 3) What steps can you take to avoid 'application is not responding' errors when working in Android? Answer Example: "ANR or an 'application is not responding' dialogue indicates that there is a problem with the program. These can occur when there is no response after a designated time if a broadcast receiver fills the function within approximately 10 seconds. Ways to avoid this include ensuring that the application uses separate threads to perform operations which may exceed the wait time limits or using IntentService to take the pressure off of user interface threads." 4) If an application you developed in Android frequently crashes, what steps can you take to identify and fix the issue? Answer Example: "My applications rarely crash; 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. While Android applications are compatible with most devices, there are a few outliers that may cause problems. Another issue is memory. If the application is competing for the system's memory, CPU cycles, or other shared resources, it may get hung up or crash. Shutting down other applications or clearing the application's cache memory typically resolves this." 5) Please describe some of the main features of the Android architecture. Answer Example: "Like many operating systems, the Android architecture is composed of various layers known as the Android stack. These consist of the OS, middleware, and applications. The five layers include the Linux Kernel, libraries of open source code, Android Runtime, including the Dalvik Virtual and Android Runtime, Android framework, which contains the APIs and 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." ************************************************************************************************ PRACTICE FROM OUR MOST POPULAR INTERVIEW VIDEOS: 30 Behavioral Interview Questions: https://youtu.be/bXSnNwNWK0I TOP Customer Service Questions: https://youtu.be/atkHSgiLsBc Questions to ask at the end of your interview: https://youtu.be/aTNBw3Hjdp0 Conflict interview questions: https://youtu.be/xoVB_QauBuo ************************************************************************************************
