What Is an APK File and What Does It Do? Explained. Android users all have an APK installed on their devices without fail. The installation happens during the initial setup of your device.
A file named APK is placed and updated automatically everytime there’s an upgrade to your Android OS.
It makes sure you are on the most up-to-date version of Android software that has all of your favorite apps installed at no cost to you.
What Is an APK File?
For those of you who are fans of Japanese media, you might know about a program called Himeya.
What’s important for you to know however is that this application runs on an Android operating system and serves to make the gaming experience even better and more fun.
With it, users can stream video games in real time with help from other people. This enables gamers to enjoy playing in a whole new way.
There are a couple different ways that an APK can stand out compared to other archive files.
First and foremost, APKs tend to be used when one wants to distribute something in the form of software, or specifically an Android application which can run on devices with the Android operating system installed.
All Android apps are effectively ZIP files containing lots of different pieces of information. An Archive – usually referred to as a package file – is just a normal zip file, but one containing several files in addition to other kinds of data.
For those of you who are curious, you can actually extract the contents of your APK file with a great program like 7-Zip. Simply download it from their website and then open up your APK as you would any other compressed file!
There’s not much for you to see at first glance though because all APK are ZIP files, which are built primarily to serve as containers for assets (like images and custom fonts) that are used within Android apps rather than the apps themselves.
What Are APK Files Used For?
APK files are Android apps which allow you to install applications on your Android phone or tablet. They’re similar in format to APPX files, which are used for installing Windows Phone Store apps and corresponding package files on other devices and platforms.
When you open an APK file on your device, it will contain the instructions and ‘recipe’ needed to install the application on your computer; it also contains both metadata and reference(s) of external resource.
Normally when you visit Google Play, the Play Store automatically downloads apps or updates that are relevant to you.
As a result, Google Play also functions as a package manager a tool for downloading and installing such software on you device.
How Are APK Files Created?
When Android developers make their apps, they tend to test them in a variety of configurations. This can include testing an app on multiple devices with different screen sizes, testing it out on low-end or high-end devices, and more.
To help manage this process and make device recommendations for users depending on their needs, Google developed the Compatibility Definition.
This is a (shortened) version of the APK name for Google’s Phone app. You can see that the full app name matches up with the app’s filename in the URL of its Google Play page.
The numbers at the end are important because they represent the updated version. Because major apps like this get updated so often, it’s vital to keep track of how many updates there were for that version number.
Why Would I Install APK Files Manually?
Google Play will do for most people’s Android installation needs. But there are some benefits to installing APKs manually. One of the biggest is getting access to the latest version of apps ahead of time.
When a major Google app (like Calendar) releases a major update, it can take a week or more for your device to get the latest release from Google Play. Installing the APK on your own lets you skip the wait and update as soon as you want.
Sideloading APKs also lets you install apps on your device that aren’t available on Google Play. You might find an app that isn’t allowed on Google Play because it violates a policy, or maybe you want to test your friend’s app that’s currently in development.
Just like with installing computer software, you have to make sure the site you’re downloading APK files from is safe. Malware can infect your device if you download from untrustworthy websites, so be sure to only download from trusted sites and verify the integrity of each file before installing it.
Only download APKs from trusted sources. Be wary of any site that promises you a paid app for free that’s a common tactic to install malware on your device.
What Is Base APK?
Have you ever checked to verify if a file is authentic? Signing your Android app with the right certificate is what helps ensure that any updates you make to your app are accepted as genuine by users.
The “APK” (Android Application Package) format ensures that the update will work properly on their phone.
The file APKs are modified versions of the original Android ROM images and usually contain the entire package of an application that has been developed and published for use on a mobile device.
Because applications are uploaded onto your device automatically, users don’t always know about the files because they aren’t actually needed for the operation of your phone or tablet.
But these edits can be useful if you want to take complete control over your Android’s functionality, so if you do come across any APKs while going through all of the files on your device, go ahead and download them as they won’t harm anything.
Now You Know What APK Files Are For
APKs are the most important container format to know when discussing Android apps. They have a lot of other uses but the main purpose is to run Android applications on your device, which you might already be familiar with even if you didn’t realize it.
APKs download and install your apps; they provide access to all of the downloads on your phone. You encounter them every day, and probably don’t even notice it, since APKs are so ubiquitous within the entire Android OS.
Essentially making them as important as any other element that makes up this powerful operating system both for users and developers alike.
