Java APK explained
Java APK is the file format used by the Android operating system and some other Android-based operating systems for distribution and installation of mobile apps, mobile games, and middleware. A file using this format can be built from source code written in either Java or Kotlin, two popular programming languages for Android development.
An APK file contains all of a program's code (such as .dex files), resources, assets, certificates, and manifest file. It is similar to other software packages such as APPX in Microsoft Windows or .app on HarmonyOS. To make an APK file, a program for Android is first compiled using a tool such as Android Studio or Visual Studio and then all of its parts are packaged into one container file.
The purpose of using an APK file is to make it easier for developers to distribute their apps to users and for users to install them on their devices. An APK file can be downloaded from various sources, such as official app stores like Google Play or Amazon Appstore, third-party websites or platforms, or directly from developers. An APK file can also be transferred from one device to another via USB cable, Bluetooth, Wi-Fi Direct, etc.
