By Step Guide To Build Android Apps Using Python
Are you curious about developing android apps but Java is not your companion? Android universe is mainly build using Java, Kotlin, Flutter, and Corona using Lua Scripting Language but in recent times, Python has made its way into every domain and android is no different. In this series of articles, we will look at how to set-up the required environment, the basics of developing an android app, referencing the documentation, and how to move ahead with your projects.
How Much Does It Cost To Make An App
The cost to create a mobile app is based on multiple factors. The type of app youre building, the features youre implementing, and the development method will have the most significant impact on the price.
You can build an app for $2,000, $20,000, $200,000, or upwards of $2 million.
In most cases, using an app development platform will be cheaper than learning how to develop an app from scratch by coding. But even within each development method, the prices will fluctuate.
For example, lets say you want to build an app with low-level coding. You can hire an experienced app developer in the US that charges $150 per hour or outsource to a first-time developer overseas for $30 per hour.
If you try to cut corners and develop your own app for as cheap as possible, your final quality will suffer. It could end up costing you more money in the long run if you try to save a few dollars now.

Fix Errors If Necessary
If you edited the XML for the layout directly, you might see some errors.
The errors occur because the buttons have changed their id and now these constraints are referencing non-existent views.
If you have these errors, fix them by updating the id of the buttons in the constraints that are underlined in red.

How To Build An App Step : Modify And Adjust
Youve taken your prototype for a spin, and youve learned that there are still a few tweaks you need to make. Now that youve seen your app in its fully functioning form, you need to call the troops back and ask they to do the same.
Ask the same people who viewed your app in its development phase to examine it in its testing phase as well. Again, open yourself up to constructive criticism, and use the feedback accordingly. Lastly, ask your developer and your designer to make any changes that you feel would be valuable to your app.
Open The Layout Editor
Troubleshooting: If you don’t see the file fragment_first.xml, confirm you are running Android Studio 3.6 or later, which is required for this codelab.
The panels to the right of the Project view comprise the Layout Editor. They may be arranged differently in your version of Android Studio, but the function is the same.
On the left is a Palette of views you can add to your app.
Below that is a Component Tree showing the views currently in this file, and how they are arranged in relation to each other.
In the center is the Design editor , which shows a visual representation of what the contents of the file will look like when compiled into an Android app. You can view the visual representation, the XML code, or both.

Resilience Is The Key To Creating Apps
As you may have realized from the information in this article, creating an Android app is not easy if you dont already know how to do so.
Understanding Java will be a big help, but even then youll still have a lot to get to grips with. If you have never coded before, your journey to create an app will be even longer.
Depending on how long you can dedicate to study, you can learn the basics of Android app creation in a few weeks and create your own app within a few months.
Even if you have a full-time job or other commitments, by sticking at it you can learn all you need to know to get started with the app creation process in a relatively short period of time.
The key is that you need to keep going. Coursera estimates that you can complete its Android App Development Specialization course in around five months by putting in just four hours per week. This is a manageable amount of time for many people.
Android App Distribution Platforms To Release Your App
Play Store, Googleâs official Android app distribution platform for mobile apps running on Android OS, is usually the go-to place for Android Apps, but itâs not the only place. Hereâs the list of some of the cool alternatives to Play Store where you can release and market your android app.
Google Play Store: Google Play, formerly Android Market, comes first in the list where you can release and market your Android app. Google Play is an official Android app distribution platform hosting nearly 3 million apps under various categories. Google Play should be your first choice when it comes to testing your app idea in the market.
Amazon Appstore: It’s the second biggest Android app distribution platform after Google Play Store. This is the biggest rival to Google Play and offers free app release under various categories. Go, get your app listed on the Amazon AppStore to further boost your app downloads.
APKPure: One of the fastest-growing mobile apps distribution platforms. The APKPure platform allows you to list both Android and iOS apps. The website receives nearly 500,000 daily visitors that shows you the huge potential to grow your app audience. â

The Other Files And Folders
There are lots more files and folders here though, so what do they all do?
In truth, you dont need to know what everything here is. But some things that are useful to know about:
The Android Manifest: This is an XML file in the res folder that defines important features of your app. That includes the orientation of the app, the activities that you want to be included in it, the version, etc.
See also: Xml: everything you need to know
Drawable: This folder is found in res. This is where you will put things like images that you want to reference later.
Values: This resource folder is a useful place to store values that will be used globally across your app. For example, this can include color codes or strings . Youll define these values in individual XML files, such as colors.xml.
Gradle: Gradle is the tool that takes all your files and bundles them into a workable APK for testing. It is also useful for generating previews etc. You wont need to worry about the files in here often, but if you want to add a dependency, this is where you will do it. Dependencies are external libraries that let you access additional functionality from within your own code.
Of course, we also have a detailed introduction to Gradle for new Android developers.

Explore The Project Structure And Layout
The upper left of the Android Studio window should look similar to the following diagram:
Based on you selecting the Basic Activity template for your project, Android Studio has set up a number of files for you. You can look at the hierarchy of the files for your app in multiple ways, one is in Project view. Project view shows your files and folders structured in a way that is convenient for working with an Android project. .)
In the Project > Android view you see three or four top-level folders below your app folder: manifests, java, java and res. You may not see java right away.
This folder contains AndroidManifest.xml. This file describes all the components of your Android app and is read by the Android runtime system when your app is executed. 2. Expand the java folder. All your Java language files are organized here. The java folder contains three subfolders:
com.example.myfirstapp: This folder contains the Java source code files for your app.
com.example.myfirstapp : This folder is where you would put your instrumented tests, which are tests that run on an Android device. It starts out with a skeleton test file.
drawable: All your app’s images will be stored in this folder.
What Are Subscription In
Subscription based In-App Purchases are described as: A product that allows users to purchase dynamic content for a set period. This type of subscription renews automatically unless cancelled by the user. This means that there is a recurring charge that will allow the user to access that specific in-app section, though only while they continue to pay to keep their subscription active.

How To Make An App: A Step
Mobile app development can be segmented into three categoriespre-development, development, and post-launch.
This guide reads best from start to finish, but feel free to click around to the sections that are most relevant to your needs. Some of you might be starting from scratch, while others might be further along in the process.
Technique #: Improve An Existing App
Have you used an app and thought, It would be so much better if this could do X? If so, thats the creative spark of a really good potential app idea!
Theres always room for improvement so if you thought that an app was sorely lacking a useful feature, chances are that you werent the only one to think that.
If the original app author isnt constantly updating and improving the app, then theres an opportunity for you to create an even better app.
One way to figure out whether or not youre right about this is to check the reviews and ratings for the original app.
Are people complaining about the same thing? Are they complaining about something different? Is the app author listening to the feedback?
As youre going to see, listening to user feedback and improving your app based on that feedback is probably the singular driving force to the success of an app.
An absent app author is sentencing his or her app to a slow death of user attrition.
The next step is to validate your idea to make sure that it has a chance to thrive in the app store.
