1. What are the earliest and latest versions of Android you have worked with?
How to Answer
Like any other operating system, Android has evolved through many different iterations. Each version is designated by a number that can contain up to three decimal places. Each version is also given a nickname such as Cupcake, Donut, Marshmallow, or Oreo. Interviewers at Doordash will ask you about your experience working with the different versions of Android to understand how long you have been programming in this environment and how familiar you are with each version. Knowing about the pedigree and evolution of the operating system will also increase your programming skills and make you more valuable to Doordash.
Written by William Swansen on November 13th, 2021
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. How would you use an AndroidManifest.xml file?
How to Answer
You probably already recognize this is a technical question. This is because you are being asked about a specific technology used in this profession. Throughout the interview with Doordash, you will be asked many technical questions. Nobody can be familiar with all of the technology used in any profession. If you are asked about something you are not familiar with, state this and explain how you would locate the information to the interviewer.
Written by William Swansen on November 13th, 2021
Answer Example
"The AndroidManifest.xml file holds the application if information Android needs before the program can be executed. Every Android application must contain this file which is stored in the root directory. Some of the functions the file performs include providing the file's name, describing the application's components, including the activities and services, and defining any classes the application will use."

4. When creating an Android app, do you prefer working with Serializable or Parcelable? Why?
How to Answer
When asking this question, the Doordash interviewer assumes that you are familiar with the terms Serializable and Parcelable. If you're not and were to ask the interviewer to define the terms, you might as well terminate the interview and leave. Being able to describe terminology, processes, and procedures is critical to succeeding during an interview for an Android developer's job with Doordash. This is why it is recommended that you take some time to review all the terms you use in this profession, even if you don't deal with them regularly. If you do come across a term you are not familiar with, answer the question by describing how you would locate the information to the interviewer.
Written by William Swansen on November 13th, 2021
Answer Example
"Virtually all applications in the Android environment have to exchange data between activities. The data is added to another activity's intent object. For this to work, the object needs to be either Serializable or Parcelable. You can designate a class Serializable by implementing the interface, and Java will automatically serialize it. The downside to this approach is that it leads to the collection of garbage code and poor performance. I prefer to use Parcelable, which was developed specifically for Android. Using this approach, the serialization is implemented manually by the code, not the development platform. Also, reflection is not used during this process, and no garbage is created, so the application's performance is not impacted."

5. How is Dalvik used in Android development projects?
How to Answer
The term Dalvik is common within the Android programming environment. This was the original runtime developed for early versions of the Android OS. It has since been discontinued and replaced by the Android Runtime, or ART. Even though the Dalvik Virtual Machine and Runtime are no longer used, you still need to know about it and be able to answer questions asked by the interviewer at Doordash. You may want to use the past tense when discussing Dalvik to demonstrate that you understand it has been succeeded by ART.
Written by William Swansen on November 13th, 2021
Answer Example
"Dalvik was the original Android Virtual Machine, or AVM, and Runtime Environment for early versions of Android. It provided Android devices the ability to execute multiple instances of virtual machines. Dalvik has since been replaced by the Android Runtime and AVM. However, it is still in use by some older applications running earlier versions of the Android OS."

7. How is Android activities different from services?
How to Answer
Every profession uses common terms which have a special meaning within the work that they do. The Doordash interviewer is asking you this question to confirm that you know the differences between activities and services within the context of Android. Since this is a technical question, you should first start by defining each of the terms and then list the differences between them. As with any technical question, keep your answer brief and to the point. You should also be prepared for follow-up questions in case the interviewer needs more information or wants to explore the topic in more detail.
Written by William Swansen on November 13th, 2021
Answer Example
"Within the context of Android, a service is a component of an application which enables it to run in the background. This is common for applications that need little user interaction and run for a long time. On the other hand, an activity is a shorter operation that runs in the foreground and can be modified or terminated by the user. Activities are used by programmers when the user interaction, as required in the activity, is dependent on other activities or services. Services are preferred when the operation needs little user interaction and can function independently."

8. Can you demonstrate the syntax you use for Toast?
How to Answer
It is common that during an interview for any software development position, you will be presented cases and asked to create the code to resolve the case or solve an issue. This is especially true for Android application developers interviewing with Doordash. While you cannot be prepared to create every line of code the interviewer may ask you about, you should be able to address the more common ones. The Doordash interviewer seeks to confirm your ability to quickly develop code when presented with a common code case. If you cannot create the code they are asking you about, acknowledge this and then detail how you would do it using typical resources available to developers.
Written by William Swansen on November 13th, 2021
Answer Example
"As you may know, Toast is a dialog that is displayed in an application confirming a requested operation initiated by the user. It is typically contained in a small dialog box on top of the user's application. The syntax for toast is:
Toast.makeText(ProjectActivity.this, 'message', Toast.LENGTH_LONG).show();"

9. What are some of the different launch modes in Android?
How to Answer
Launch mode in the Android applications is what generates and activates new instances within its ask that originate in the activity. There are several different launch modes Android application developers can employ. You should be familiar with these and be able to describe them to the interviewer at Doordash. When answering this type of technical question, you may want to provide examples to illustrate your answer.
Written by William Swansen on November 13th, 2021
Answer Example
"The three main launch modes Android applications use include Standard, SingleTopic, and SingleTask. Standard will generate a new instance of an activity in the original task. This allows me to create several instances of the same activity. SingleTopic is similar to Standard except if the application recognizes the previous instance of an activity, a new instance will not be created. Instead, the intent called by the activity will be passed to the 'onNewIntent' method. The final launch mode, SingleTask, pushes a new instance to the task as the root. For example, if the current stack of activities is A then B then C then D, and activity B is relaunched, SingleTask will create a launch mode leaving A and B and eliminating C and D."

10. If an application you developed in Android for Doordash frequently crashes, what steps can you take to identify and fix the issue?
How to Answer
It is exceedingly rare that an application will crash once properly developed, tested, and implemented. However, certain circumstances will cause applications to crash. As a prospective Doordash Android developer, you should be aware of these and program your code to avoid them if an application crashes while in production, you should be able to provide advice to the Doordash support team or end users as to 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.
Written by William Swansen on November 13th, 2021
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."
Written by William Swansen on November 13th, 2021
Technical
11. What steps can you take to avoid 'application is not responding' errors when working in Android?
How to Answer
An ANR or 'application not responding' dialog box will appear whenever an application is not responding. There are several reasons that this may occur, and as an Android developer, you should be familiar with these and know how to avoid or correct them. This is an example of an operational question with which the Doordash interviewer seeks to understand how you go about doing this job. Operational, like technical questions, should be responded to directly and succinctly, with little embellishment. The interviewer will ask you a follow-up question if they need additional information.
Written by William Swansen on November 13th, 2021
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."

Technical
12. Can you explain the difference between implicit and explicit intent?
How to Answer
This question may seem similar to the one you were asked earlier in the Doordash interview. It is an example of a follow-up question that the interviewer uses to explore a topic in more detail. When interviewers ask follow-up questions, it indicates that you did not provide enough information with your initial answer, or they have a specific interest in this topic and want to delve into your expertise further. In either case, continue to keep your answers brief and to the point, and always anticipate additional follow-up questions.
Written by William Swansen on November 13th, 2021
Answer Example
"Explicit intents, much like their name, let the system know about a specific activity needed to handle the intent and define the target component. An implicit intent enables you to affirm the action you want to execute. Android will then identify the components registered to handle the action based on data contained in the intent."

13. When working in Android, what is context?
How to Answer
Context is another term that has a special meaning within Android. If you have experience in the field you already know this and can easily respond to this question. However, it is still advised that you take time to review the terminology, processes, and procedures used by an Android developer before the interview with Doordash. This will help refresh your memory and put this information in the front of your mind, ready to be retrieved during the Doordash interview.
Written by William Swansen on November 13th, 2021
Answer Example
"Context, as used within Android, is the context of the current state of the application or object. There are two types of context. The first is activity context, which is attached to the lifecycle of an activity. IT informs the program of the current state of the activity. The other type is application context, which is attached to the lifecycle of the application. This performs a similar function, but at a higher level and is not dependent on individual activities."

14. In the context of Android, what is an intent, and can you provide some of the types of intents?
How to Answer
Intent is another fundamental component of the Android OS. As an android developer, you will know this and be able to respond to this question quickly and accurately. You should use your best judgment regarding how much information to provide when answering this question. Some interviewers at Doordash may prefer a brief, high-level response, while others expect you to go into great detail. As the interview progresses, you should be able to determine the type of responses the Doordash interviewer prefers and use this to frame your answers.
Written by William Swansen on November 13th, 2021
Answer Example
"Intent is an object used to request a response or activity from other components within the Android application. Another use for intent is to initiate an activity, such as sending an SMS, displaying a map, or opening a file. If the intent is used to invoke components of the system, it is called implicit intent. Explicit intents invoke activity classes which are the compiled form of a .java file used to produce an .apk file."
