Best Ways To Develop Android Applications

Many programmers will tell you that some of the biggest mistakes they’ve made have been through trial and error. It’s true— development is a skill that takes time and practice. As Android developers improve their skills over time, they’ll make fewer and fewer mistakes, leading to cleaner code, software that performs better, and fewer bugs. It’s all part of the learning curve.

However, even an experienced developer can benefit from reviewing some of the best practices that Google lays out for Android projects. To help you start your Android app project off on the right foot, here are a few tips and best practices to consider.

LEARN XML AND JAVA

Extensible markup language (XML) is a markup language that’s the foundation for the Android user interface (UI) and elements. Java is the back end coding language platform, and its used with binding functionality with your XML layout.
For developers used to binding elements even in web design, this should be intuitive for you. The data element is defined in java, and then object data is bound to front end layout element.
Before you get started in android development, you should be proficient in both of these technologies. understanding the fundamentals of XML format is relatively easy, but java is an object oriented language and object oriented programming will be challenging if you are not familiar with the similar concept. A newer language and framework, Kotlin has been introduced to help advanced android development. It can also used with legacy java apps as Kotlin co-operates with java code.
The best way to learn java code is to dive into someone's else code. GitHub is filled with open source projects that helps you to understand java and OOP concepts. The better your OOP skills are, the easier it will be to create a better coded, less buggy android app.

UNDERSTAND MEMORY LIMITATIONS

Mobile devices don’t have the high memory limitations that desktops have. In mobile programming, you must learn to code with smaller memory limitations in mind. If you carelessly use memory on an Android device, you run the risk of your app crashing due to “out of memory” errors.
To work around this, use services on the device sparingly and release memory resources when your app is hidden. You can release memory resources by overriding the onTrimMemory event although you should know that this isn’t a magic solution that allows you to ignore other performance optimization throughout your code.
Google also recommends that you avoid or at least reduce the use of bitmaps to lower the memory use when your app is running on the device. You can also use third-party tools such as Picasso or Fresco.

USE THE DEFAULT KEYBOARD BASED ON REQUIRED INPUT

When the user clicks an input text box in an app, the keyboard that pops up should automatically display the characters required to send the right kind of input. For example, if the user is entering a phone number, a numerical keyboard should be the default keyboard. If the app is requesting an email, a keyboard with characters, @ symbols, and a .com key should display.
The EditText box can be used for characters, numbers, or alphanumeric input. The type of input you set for your EditText drives the keyboard that displays on the device.
Notice that the last property indicates that the input should be numeric. When the user clicks this form element, a numeric keyboard displays. Using this standard makes it easier for your users to fill out forms by providing them with the type of input they should be using.

Simpler Ways To Develop Android Applications

(1) The first step is to learn Java. Trying to learn android without knowing java is like jumping to ride a Ferrari without learning to drive in the first place!
(2) Once you are acquainted with a java essential, you can get going with android development tutorials.
(3) Next you can search for good video tutorials so that you can have a visual and hand- on learning. You can do random search in google and/or YouTube
(4) Every theoretical knowledge needs practical implementation. if you are grasped what android android programming is about, then it's suggested you start building an application based on your learning. After all, practice makes you perfect.

BEST WAYS DEVELOP ANDROID APPPLICATION

1. Install java jdk software from oracle website
2. install android studio
3. Under the quick start menu, select "select a new android studio project"
4. On the "create new project" window that opens, name your project "Hello World"
5. Note where the project file is stored and change it if desired
6. Make sure on that "phone and tablet" is the only box checked
7. If you are planning to test the app on your phone, make sure the minimum SDK is below your phone's operating system level.
8. Click "Next."
9. Select "Blank Activity."
10. Click "Next."
11. Leave all of the Activity name fields as they are.
12. Click "Finish."
13. Edit the Welcome Message in the Main ActivityNavigate to the activity_main.XML tab if it is not already open.
14. Make sure that the Design tab is open on the 4.2activity_main.XML display.
15. Click and drag the "Hello, world!" from the upper left corner        of the phone display to the center of the screen.
