With new Android devices launching every month, keeping your app compatible across them all can feel impossible.
Android dominates the market with over 71% share, meaning your APK must perform flawlessly across countless screen sizes, OS versions, and hardware setups.
Building and maintaining an in-house device lab is costly and time-consuming—but there’s a smarter way. You can now run and test APKs online directly in your browser, saving hours of setup while ensuring full Android coverage. This article explains how to do it.
How to Open APK Files in a Browser
Change the extension to .zip and unzip it to uncompress the file. Then you can open the file. You can also use a unzip tool to extract the files and folders compressed inside an APK file.
Once you open the APK file, you can view all its contents. All Android files have the same core structure. Here are the common files and folders in an APK file:
- AndroidManifest.xml
- META-INF/
- classes.dex
- res/
- lib/
- assets/
- resources.arsc
Apart from opening an APK file, installing an APK file is also simple depending on the Android version of your device.
To ensure smooth APK testing and compatibility, expert advice can guide you through the best tools and practices.
