Mistakes are an inevitable part if you are going through the process of app development. However, if you can acknowledge those Android mistakes before developing your Android app, you can deter yourself from those mistakes. Besides, you have to understand that mobile apps play an essential role in the competitive business. So, it would help if you take some extra care while crafting an app so that it comes out errorless. 

Hence, we are giving you a list of 10 common mistakes that you should note and avoid while going for an app development for your business.

1. No use of intents

The intent is a message object. It serves the purpose of communication between the Android components like content providers, activities, broadcast receivers, as well as services. Besides, intents also play a significant role in transferring data between the activities. So, it would be best if you always used intents while coming up with an app. It will make your app to reach the mark.

2. No use of fragments

Another common mistake that an app developer must avoid is not using any fragments. The fragment is nothing but a small part of the activity. The fundamental purpose of a fragment is to split the activities into sub-activities. While fragmenting your activities, you don’t have to take any permission inside the manifest file. 

Moreover, fragment also helps a developer to maintain a stable user interface, which they can optimize for various Android devices. Also, fragments are quite convenient as you can reuse the fragments for different activities.

3. ANR – It blocks the main thread

To keep the user interface responsive, the main thread is used. Well, a thread is nothing but a thread of execution used in a program. In that case, you can use JAVA Virtual Machine. With the help of that tool, you can come up with numerous threads of execution that will run simultaneously. 

Thus, the thread takes the interactions and actions of a user in the activity. To be precise, it will take charge when the application of the user shows ANR (Application Not Responding). So, while you are in the way of tailoring an app, discuss this issue with your Android app developer.

4. Not crafting the Gradle precisely or not using any library

If you are creating an app, it will work on networks, JSON/XML parsing, image uploading, or any social media login. Hence, there is a possibility that your app will not work properly. To ensure that your app is working efficiently, you have to incorporate libraries. Thus, there are some key points that you should note. 

1. Opt for the libraries like Picasso (image uploading/loading), Volley (Network Access), and Gson (JSON Parsing).

2. Also, utilize the Gradle building, and implement Gradle whenever they are required.

5. Avoiding the Bitmap usage or not comprehending the Bitmaps

You have to use images for your apps and for sure. So, while working with the images, you must opt for Bitmap Class. It will help you to craft Bitmap images. Besides, there are several places where you can use Bitmap images. Some of the areas where you can use Bitmap images are files, resources, as well as InputStream class.

6. Not setting, compiled version, minSdkversion, and targetSdkVersion in the build.Gradle file

It is very important to control which app is well-matched with which API. Also, you need to comprehend the required API level. And for all these things, you have to check compileSdkKversion, targeted version, and minSdkversion. Now, let us look at the different purposes of these things.

1. compileSdkKversion is used to compile the Android SDK’s version and to compile the Gradle.min

2. Sdkversion serves the purpose of an Android app’s minimum API support. 

3. Finally, the target SDK version provides you with the targeted API, which supports your app. Well, that signifies the fact that the lower versions of the target SDK version are also attuned to your apps. 

7. Poor memory management or not optimizing the usage of bandwidth

The first thing that you should know is that memory management is one of the most complex fields in the area of computer science. Also, there are a lot of techniques developed, which makes it more efficient to work. So, to help you out, we will discuss some of the most significant memory management issues. So, try to remember the points that we are about to introduce. It will allow you to avoid memory leaks and will provide you with better memory management. 

1. Make sure not to keep long-lived references in case of a context-activity.

2. Also, try to avoid the non-static inner classes if you don’t have control of the activity and its life cycle. The best option for you is to use a static inner class and also incorporate a weak reference inside the activity.

3. Instead of the context-activity, try to use context application.

4. Besides, you should know that a garbage collector is not an assurance for your memory leaks. Moreover, most of the time, memory leaks happen when there is too little memory available. It also happens when your memory is too fragmented to assign a large object.

8. Not making your app compatible with all the devices

It is one of the prevalent mistakes that most app developers make during Android app development. You must acknowledge that if you are not creating an app that is compatible with all the devices, it can never be user-friendly. Therefore, you should craft your app in such a way that it should run on the basis of user experience. 

9. Not giving importance to the user-friendliness of the app

User experience is one of the essential things when it comes to the success of an app. If the UI of your app is not up to the mark, there is a possibility that your app will witness failure. There are multiple ways by which you can make your app user-friendly. The best thing to do is to opt for material design. It will improve user efficiency, interaction, and usability. 

Besides, you must also use toolbars, RecyclerView, floating action buttons, Palette, and CardView. Well, you have used different things for different devices. Well, if people witness bugs in your app, they will stop using it.

10. Not keeping the codes simple

Whenever your developer is writing code, tell him or her to keep it simple. The main reason is that your developer has to work with a team. So, if the codes are complicated, it will be hard for your developer to explain them to his or her team.

So, these are some of the mistakes that most of the Android app development companies and developers make. Therefore, try to avoid these mistakes as much as possible and make your app appealing to your customers. We assure you that if you can avoid these mistakes, your app will work according to your expectations.
