What is JAR file?
The JAR (Java Archive) file extension is associated with the Java Runtime Environment (JRE). It is a platform independent file format used to combine multiple class files and associated metadata time into one file for distribution. JAR files are not dependent on any specific hardware or operating system, and can be used in any Java environment. It works like a ZIP file, by compressing more than one files into a single unit for easier management and storage. [ ⏩ ] JAR file extension
What is APK file?
APK files are Android applications used by the Google Android operating system. They are packaged in a compressed .zip format and contain all of the necessary executable code, resources, assets and manifest files that make an Android app. Compression and Requirements The APK files are compressed using the Zip algorithm with extension .ZIP, which makes them smaller in size and optimized for distribution.

How to convert the file from JAR to APK?
To successfully convert the JAR file to APK, you should install one of the applications from the list. After installing the software, open the program and select the file you want to convert (file-name.JAR). The next step is to select the target format from the list, in this case APK (usually converters allow you to convert to several different formats, so check out their features - maybe one of the available formats will suit you more than APK).
What is a file conversion?
A data conversion is normally an automated process to some extent. The effect of the operation of one program is automatically the input product of another application. If that does not happen we need to help the process a little bit and convert the file on our own, e.g. JAR to APK. To obtain a matched structure of the data, it is necessary to use an appropriate converter.
Program for converting JAR files to APK files is a kind of a "binary code translator" compensating for the differences in the code or translating it in such a way so that another application could use it. For us, as users, the visible change will be only another file extension. (After converting the file, it will be the extension APK, while before this step we had the JAR file). For the programs, the difference is on a much higher level – either the application will be able to open a new APK file, or not.
