The Challenges of Android App Development

While developing an app there are a lots of challenges that a developer face. A difference is experienced by the user in performance, compatibility and UI but it don't create an error in the app.  

Following are some of the challenges that occur while developing an App:-

1. Building for a multi-screen world

2. Getting performance right

3. Keeping our code and our user secure

4. Remaining compatible with older platform versions 

1. Building for a multi-screen world :-  The devices that support android operating system comes in different sizes and shapes even some of that devices has there own UI. For instance, each manufacturer (oppo, Redmi etc.) offers different features with respect to keyboard forms, screen size, or camera buttons. Which creates a big challenge to a developer because an app running on one device may look a bit different on another device. So, it is responsibility of the developer to maintain uniformity by designing such UI elements that can work uniformly on all devices .

2. Getting performance right :- An app performance can be judge by the following points :

                                               1. How fast that app runs ?

                                               2. How easily that app connects to the network ?

                                               3. How well that app manages battery and memory usage ?

To get maximum app performance a developer should take care of the above points while writing code. Also, coding should be done in such a manner that resource utilization is balanced and distributed optimally. For example, you will have to balance the background services by enabling them only when necessary; this will save battery life of the user’s device.

3. Keeping our code and our user secure:- If you are making any kind of application the first thing that you should kept in mind is the encryption. Android Studio provide ProGuard tool, which detects and removes unused classes, fields, methods ,attributes , and encrypt all of your app's code and resources while packaging the app.

To protect your user's critical information such as logins and passwords, you must secure the communication channel to protect data in transit (across the Internet) as well as data at rest (on the device). Developer should use all possible precautions to secure users data and code. A good example of it is, What's App that provide end to end encryption. 

4. Remaining compatible with older platform versions:- To remain compatible with older platform versions means that the developer should ensure that the app can still run on devices with older platform versions. For example , suppose a developer is developing an app which run on the recent android version (let it be android Oreo). Now, in this case developer should also take care that his/her app should also support previous android versions ( like kitkat,etc.). Moreover,  it is impractical to focus only on the most recent Android version, as not all users may have upgraded devices.
