Top Android Interview Questions and Answers for Freshers In 2023

Desired Behavioral Traits

1) Keeping calm under pressure :

Stress tests are an important part of these interviews. Here is why:

Let us suppose you are selected for the job, and are working on an overseas Android development project.

You will have to deal with clients and co-workers you don’t personally know; they might have completely different work cultures. You would be expected to exercise a great deal of patience while dealing with them. This is why your forbearance will be tested in an interview.

The parameters you would be graded on might be:

a) Your immediate reaction to stressful situations. (Do you retain your calm or run scared?)

b) When faced with adversity, are you impulsive or thoughtful.

c) Are you intuitive and plan for such situations beforehand, or do you almost never foresee them? (For instance: if you are preparing for technical Android interview questions and stress interview beforehand, you are on the right track :)).

You might think it possible to acquire these qualities on the job. It’s true, but if the interviewer has to choose between two freshers with the same technical skills, then personality would play an important role.

2) Be confident, but don’t go overboard:

Another thing that the interviewers don’t appreciate is arrogance. Positive attitude is important, but don’t be an overconfident know-it-all. Be yourself, and don’t pretend to know things you don’t. It would hardly take a few minutes for a skilled interviewer to figure you out, so don’t bother with the exaggerations.

An Android professional who was recently a part of his organization’s interview panel for an ongoing recruitment drive, shared an incident with us:

“There was this one interviewee who had aced his aptitude test, and had fared well at the technical test too. He was so far the best of the bunch. We all had our minds almost completely made up about the guy. He had the knowledge, the skills and the attitude. But, one move on his part ruined it for him.

He was insistent on having worked on Android platform in the past. Fair enough! But, when cross-questioned he did not have enough knowledge to support his claims (which by the way, were pretty bold). It was an excusable mistake, but what turned it around completely was the way he handled the situation that followed.

His (over)confidence provoked the panel, and what was meant to be a friendly interaction turned into a fierce stress interview. He, of course could not handle it very well. The poor guy was obviously shaken up by the turn of events, so had his defenses up. However, he would have come across as arrogant in a real-world situation (handling a client).

He of course, did not get the position, even though he had the required skills.”

This is a great example of how overconfidence and improper stress handling can mess it up, even when you have the required skills.

3) Communication skills:

Knowledge of English language is of course not the foremost thing looked at, but is important nonetheless.

Now you have an idea of the kind of personality parameters you would be graded on, in addition to the most common technical Android interview questions.

Q6. How do you handle multiple resolution screens in android?

The following five properties help you to achieve multiple resolution screens in android:

• Screen size – Screen sizes are divided into four generalized sizes: small, normal, large, and extra-large.
• Screen density – Screen densities are also divided into four generalized densities: low, medium, high, and extra-high.
• Orientation – When user rotates the device the orientation of the device also gets changed.
• Resolution – The total number of physical pixels on a screen.
• Density – independent pixel (dp) – Provides you a density-independent way to define your layouts.

Q7. What is the importance of declaring permissions in android application development?

The limitation is imposed to protect critical data and code that could be misused to distort or damage the user experience. If an application needs access to a feature protected by a permission, it must declare that it requires that permission with a <uses-permission> element in the manifest. Then, when the application is installed on the device, the user determines whether or not to grant the requested permission by checking the authorities that signed the application’s certificates and, in some cases, asking the user. – reference Android Developers.

Q8. If I have all the drawable folders like xhdpi, hdpi, mdpi and ldpi and I am running my application on xhdpi devices,the images will be picked up from which folder.(I have not placed any image in xhdpi).
