You don't have to rely solely on the Google Play Store to enjoy great apps on your smartphone! You can download an Android APK app using a specific file. Admittedly, the process is a bit more complex than clicking an “Install” button, but it lets you access unique and sometimes essential tools.
Using an Android APK lets you choose from a wide range of mobile software. You can use apps that aren't available in the app store or are still in beta. So, how do you download and install these package files? We'll explain everything!
What is an Android APK app?
APK stands for Android Package Kit. This file format is used by Android to distribute and install applications. It contains all the elements needed for an app to run properly on your phone. Just as Windows uses a .exe file to install software, the APK does the same for Android. In other words, when an Android developer finishes the creation of an Android applicationcreation of an Android app, it's the APK that will allow it to be installed on your device.
An APK is also an archive file, like ZIP and RAR files. That means it contains multiple folders as well as metadata useful to the application. APKs are in fact a variant of the JAR (Java Archive) file format, since much of Android is built with the Java language.
All APKs are ZIP files at their core, but they must include additional information to function correctly. So, all APKs are ZIPs… but not all ZIPs are APKs!
An Android APK app therefore requires installing this archive on your smartphone in order to work properly.
Why install an Android APK app?
There are several reasons you might want to download an APK app to your Android smartphone:
- Get exclusive access to a new Android version
- Install an app that isn't available in your country via the Play Store
- Download an update early
- Test an app before it's published to the store
- Reinstall an older version of an app (because the update doesn't suit you or isn't compatible with your smartphone)
- Install apps when you don't have access to the Google Play Store
How are APK files created?
When a developer creates an Android app, they typically use Android Studio. Once the app is ready, the IDE compiles it and places it into a container that is nothing more than an APK file.
APKs can have any name, but they generally keep the “.apk” file extension so operating systems know how to interpret them. When you open an APK, it contains the installation instructions and provides information to your device, allowing it to interpret the data and convert it into an app.
When you download or update an app on Google Play, it automatically installs the APK. The app store therefore acts as a package manager.
However, because Android is open by nature, Google Play is not the only way to find and install APKs. It’s easy to obtain an APK file from another platform and install it manually. We'll show you how later in this article…
How to download an Android APK app?
To download an Android APK app to your smartphone or tablet, open your web browser.
- Download the app of your choice.
- From the notification bar, tap the downloaded file and install it.
If your web browser refuses to open the file after downloading, check your file manager. Go to your device's "Downloads" folder — you should find the APK there.
To ensure it installs properly, be sure to read the requested permissions carefully and grant only those that are essential.
How to allow installation of an APK file on Android?
Because the Android APK app does not come from Google Play, the operating system or your browser may block its installation on the phone. You must first allow access to these so-called "unknown" apps.
Here's how to do it:
- Go to your device settings and tap Apps & notifications.
- Click on "Chrome" or the browser you will use to download the Android APK.
- Tap Permissions and enable the "Allowed" toggle to permit installation of apps from this source.
On some Android smartphones, you need to:
- Go to "Settings" then "Security".
- Then click "Unknown sources" to allow installation of apps not from Google Play.
You can also grant access to your app after downloading the APK from your browser. By clicking the downloaded file to install it, you will first be asked to allow installation from unknown sources.
Also consider disabling the verification features offered by Play Protect. The tool may uninstall your Android APK on the grounds that it did not come from the official app store.
Hire an Android developer to create an APK app
Want to create your own Android APK app? Our advice: hire a freelance developer who specializes in Android!
An Android developer is responsible for designing and building apps for devices running that operating system. These Android apps are generally written in Java, though the developer may choose a different programming language depending on your needs.
This coding specialist mainly handles the development process by creating the app's features. They also design the user interface with a specific flow that favors navigation and the mobile user's experience. The goal is to guide the user effectively to complete the expected actions.
The Android developer builds the app's architecture by writing clean code. Their role also includes minimizing or eliminating bugs that could come from the Android APK. By hiring this professional, you get a quality app and ensure the security of your data.
How to choose a developer for your Android APK app?
To choose the right Android developer for your APK app, here are some criteria to check:
Knowledge of programming languages
Programming languages such as C, C++, C#, Java, Kotlin or JavaScript are important for any Android developer.
- Java: it is the official language for Android development and is supported by Android Studio.
- Kotlin: it is the new official Android language. It is similar but easier to code than Java.
- C++: Android Studio supports C++ in combination with the Java NDK. It is used for game development. Some developers like to use it to build certain parts of an app.
- C#: this language is a more user-friendly alternative to C and C++. It is also easier to get started with than Java.
- JavaScript: it allows you to create apps using the same code used to build a website.
A professional developer should be proficient in at least two of these languages.
Additional software knowledge
In addition to programming languages, your Android developer should have other technical knowledge, such as:
Mastery of databases
Knowledge of databases proves important for any Android developer. They should master the most popular ones such as MySQL, PostgreSQL, Redis, MongoDB, MariaDB, and SQLite.
SQLite remains ideal for mobile applications and is useful for persistent data storage.
Knowledge of Android Studio
Android Studio is an integrated development environment (IDE) in which Android applications are developed. It provides the tools to quickly build an APK for every type of device running this operating system.
To work with Android Studio, you need to know XML for design and Java or Kotlin for writing code.
Knowledge of the Android SDK and the different Android versions
SDK stands for Software Development Kit. It is made up of Java code modules that allow developers to access smartphone functions like the camera, contacts, or GPS.
There are many versions of Android, so a freelance developer must keep up to date. This will allow them to create an application suitable for all users.
Knowledge of the various APIs
API stands for Application Programming Interface. It enables communication between different programs. For example, if you want to add weather data to your app, you must use an API.
The Android developer must also be familiar with Google's Material Design guidelines to avoid your APK being considered a threat to mobile users.
Soft skills
Beyond technical skills, the Android developer you choose should possess certain human qualities, notably:
Communication skills
Developing an application is a team effort. The developer will need to communicate regularly with you or your team. Listening skills and an ability to respond to needs remain essential in creating a high-performing Android APK.
Attention to detail
The developer will have to write hundreds of lines of code. If a character or letter is incorrect, the code will not work. Attention to detail will enable them to design a bug-free application within the allotted time.
Adaptability
The world of mobile applications is constantly evolving. New programming languages may appear, standards can change, and software evolves. An application developer must be able to adapt.
