With the rapid expansion of devices operating in Android, it is no surprise that many students strive to become Android programmers. Android programming is fun and exciting, but along with this also come complicated assignments.
Those who study programming with a focus on Android programming will agree that sometimes, you can have no clue how to deal with a particular task. And the problem is, although Android programming is viral these days, it’s still hard to find helpful tips and hints to handle homework. This article spotlights the best tips so you can complete any Android exercise. Getting familiar with ADB commands is also a part of Android programming. Do not forget to check out our huge list with explanations.
Get familiar with Java design patterns
One of the best ways to get programming homework help and invest in your future career is to learn some Java design patterns. If you are a first or second-year student, then, of course, the odds are high that you’ll employ lots of your knowledge of design patterns. Anyways, learning them will not only improve your skills. It will also make your project or whatever it is you are working on better and more professional.
Aside from that, you will also become a more valuable player when knowing Java design patterns. Even in academia, you may cooperate with other colleagues-developers, so being on the same page with them is a must. Try getting familiar with patterns like Facades, Decorator, and Factory. Even knowing this little will make your collaborative work more fruitful and productive.
Make use of libraries
Needless to say that rolling your own code is often demanding and pointless, mainly because you can use library code and get the same outcomes. In such a way, you also save yourself plenty of time you can devote to other, no less crucial matters.
Indubitably, that’s impressive if you can code a loop on a Nexus One with the JIT (just-in-time) compiler. However, it doesn’t do you any good because, well, the System.arraycopy ( ) technique is over eight times faster.
Eschew unnecessary objects
Android programming requires paying attention to multiple hiccups. And the proper distribution of memory is one of them. When creating objects, you must be fully aware of what you are creating and why. More important, you should remember that anything you create will come at the price of your battery drain. How so?
See, every object collects garbage. This garbage is usually annoying in that you have to allocate memory to process it. And this memory has its limits. You can’t let your memory be siphoned off. Otherwise, the battery will die quickly.
Undoubtedly, today’s technologies and knowledge allow programmers to create concurrent garbage collectors to minimize the battery drain. But still, it’s always better to avoid overloading the system with objects to ensure smooth, undisturbed work. Below are some examples of how to handle the issue of unnecessary and redundant objects:
- Return a substring of the original data when trying to extract strings from a specific set of input data. Students often make a common mistake attempting to create a copy of objects. Try to avoid doing that.
- Change your signature and implementation when returning a string. It will help you save memory and make the function do the append directly.
Think several steps ahead and use Frameworks and Development Tools
If your homework isn’t complicated, i.e., your teacher doesn’t require you to take complicated steps, you can skip this tip. Designing the UX and UI of the Android mobile app with design guidelines circulating the web is effortless.
However, if your job is to create, test, and improve the app and make it work, you should use frameworks and development tools.
Such tools will allow you to better functionality and add various features at any given time. The great thing about these development tools is that you don’t necessarily need to write additional code. They let you create and maintain the app.
Embrace Cloud Technologies
Studying Android programming is challenging, as it always calls for learning and implementing new methods and approaches. Specific tasks require using unique strategies to build/test/maintain an app. If some of your assignments request you to do the same, you may want to adopt cloud technologies. The latter can come in handy when dealing with system fragmentation and other potential issues while developing and testing an app. Besides, cloud-based technologies will enable you to build anything you want without using the physical infrastructure.
Speed up your Android code by omitting floating-point
Floating points are now a thing of the past. The reason people refrain from using float is that it is way too slow to execute code. Instead, they implement integers and make the code run twice faster. When space is not an issue, meaning you use desktop machines, lean toward double than float.
Strive for making the User Interface swift and responsive
With the number of Android-powered devices, creating something meaningful has become laborious. Users are picky, and it’s challenging to please them. Yet, there is one thing everyone appreciates a lot – good UI. The faster and more appealing it is, the higher the chances the user will prefer your product over others.
You don’t need top-notch hardware and solid programming skills to make the UI speedy and responsive. Start by making the layouts straightforward and the layers fast. If your program has long-running processes, aim for moving them from the main thread. We also encourage you to check the running time of every single operation. It might be time-consuming, but doing that when debugging the UI will help you evaluate your code’s merits and demerits.
Finally, using TDD may well help you deal with homework and elevate its quality significantly. TDD stands for test-driven development, a way of making sure every script fits the code and works correctly. TDD is essential in professional programming circles because it has a lasting influence. The strategy accelerates development time, improves documentation, structures the code, and many more.
Android programming is in the limelight these days, which is why the number of students interested in the branch has recently spiked. Regardless of its popularity, studying Android programming isn’t easy. Students have to deal with many programming tasks that differ in requirements, problems, and solutions throughout the academic year. Provided are a few tips to cope with Android home assignments. Hopefully, they will help you score a high and satisfactory grade.
