Where are APK files used?
Installing apps manually using an APK file is called sideloading. There are several benefits of installing an app from an APK file. For instance, when updates are released for major Google apps, it can take a while (usually a week or so) before your device has access to it. With an APK file, you can skip the waiting period and access the update right away. APK files are also handy when you want to download an app that is not available on the Play Store. However, one must be careful while downloading APKs from unfamiliar sites. Certain sites provide free APKs for downloading paid apps. This brings us to the next section. Are APK files safe?
How safe are APK files?
Not all websites are safe. Apps that violate terms of conditions of use are not listed in Play Store. To download such apps, you have to perform side-loading. While Play Store identifies malicious apps and removes them, it is a good practice to exercise caution from your side as well. While downloading an APK from a third-party website, there is a possibility of installing malware or ransomware that is made to look like a legitimate app. Research online for trusted websites to download APKs from.
How to open an APK file
Although APK files can be opened in many OSs, they are primarily used in Android devices. In this section, we shall see how to open an APK file in various devices.
1. Open an APK file on an Android device
For applications that are downloaded from Google Play Store, APK files just have to be downloaded and opened. However, the system blocks files are downloaded from unknown sources. The user can, however, change this setting so that you can download APK files from sources other than Google Play Store. The following steps will bypass the restriction.
Depending on the version of Android you are using, follow one of the three methods listed below:
- Settings Security.
- Settings Apps and notifications.
- Settings Apps and notifications Advanced Special app access Install unknown apps.
In some devices, permitting a certain app to download APK files from all sources would suffice. Or you can just go to settings and enable the ‘Install unknown apps or unknown sources’ option. In some cases, the APK file does not open. Then, the user can use a file manager app such as Astro File Manager or ES File Explorer File Manager to browse for the APK file.
2. Open an APK file on a Windows PC
To open an APK file on a Windows device, the first step is to install an Android Emulator. Blue Stacks is a popular Android emulator used in Windows. Open the emulator My Apps Install the .apk file.
3. Can you open an APK file on an iOS device?
APK files are not compatible with iOS devices as the OS is built differently. Opening an APK file on an iPhone or an iPad is not possible. The file works differently than the way the apps on these devices function.
4. Open an APK file on a Mac
There is a Google Chrome extension called ARC Welder for testing Android apps. Although it is meant for Chrome OS, it works on a couple of other operating systems too. Therefore, if you install the app within the chrome browser, it is possible to open the APK file on your Windows system or a Mac.
5. Extraction of APK files
A file extractor tool can be used to open an APK file in any operating system. A program such as PeaZip or 7-Zip can be used to check the various components of an APK. The tool only allows you to extract the various files and folders in the APK. You will not be able to use the APK file on your system. For this, you will have to download an Android emulator.
Contents of an APK file
An APK file is usually an archive of multiple files and folders required for an Android program/app. Some of the commonly found files are listed below.
- arsc – contains all the compiled resources.
- xml – contains details such as name, version, and contents of the APK file.
- dex – contains the compiled Java classes that need to be run on the device.
- Res/ – contains resources not compiled in resources.arsc.

Why should you install an APK File?
APK files are a way to access apps that are restricted in your region. Sometimes, you can install an APK file to get access to new features and updates before their official release. Also, if you realize that you do not like an update, you can install an older version. If for some reason, you do not have access to Google Play Store, then APKs are the only way to install apps on your device. However, remain cautious as some websites have APKs for pirated apps. This is not legal, and you may get into trouble for downloading such apps. Some websites that have previous versions of an app may contain malware. So, do not blindly download APKs from any website online.
Converting an APK file
Files such as MP4s and PDFs are supported on multiple platforms. Therefore, one can easily use a file converter program to convert these files from one type to another. However, with APK files, this is not the case. APKs run only on specific devices. A simple file converter program will not do the job.
It is not possible to convert an APK file to IPS type (used in iOS) or to .exe file type (used in Windows). It can be converted to zip format. The APK file is opened in a file converter and repackaged as a zip. Renaming the .apk file to .zip will work only in case of APK files because APKS are already in zip format, they only have the .apk extension.
Most of the time, converting an APK file for an iOS device is not required as the developers release their apps on both platforms. To open an Android app on a Windows system, install a Windows an APK opener. APK files can be opened on a Blackberry device using an APK to BAR converter program. Upload the APK to Good e-Reader Online APK to BAR converter. After conversion, you may download the file in BAR format to your device.
