What is APK file?

File with an APK extension contains a compressed archive with an application, game or some firmware for the Android system. It cannot exceed 100MB – such restriction is being implied by the Google Play store. It is possible to add resources of an application contained within up to 2 additional files, up to 2GB each.

Structure of APK file

Structure of APK files is based on the JAR archive – they may contain some specific subfolders:

  • res - with a description of the resources in an uncompiled form,
  • lib – contains compiled sources and application libraries, divided according to different computing platforms,
  • META-INF – with files containing information about the package, for instance – the MANIFEST.MF file, or certificates,
  • assets – which contains various resources used by the app.

Android Package Kit files are used to create and distribute programs for mobile platforms operating on Android system. The content of APK files can be unpacked with most decompression programs supporting ZIP compression. Installing APK packages external to the Play Store, on a device operating on Android, is impossible by default - the security measures must be disabled within system settings.

Conversion of a APK file

When you install one of the applications from the list of programs that you found here, you should be able to open or edit the file with the APK extension without any issue. However, if you still have problems with this, you may use the option of APK file conversion to a different format.

We hope we helped you solve the problem with the APK file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.

What else may cause problems?

There can be more reasons which determine that you are not able to open the APK file (apart from the lack of the proper application installed).

First - the APK file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the APK file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the APK file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the APK file has not been completed and it cannot be opened properly).
