Your Android device can run Java games and apps, but it isn’t designed to do so, and hence you don’t find any Java emulators on the Play Store to run jar files on Android devices.

However, if you must open a jar file on your Android device, there are a few third-party apps you can install to your Android device to run java apps & games. But know that you need root access on your Android device to run Java.

In our tests, we found the JBED app to be the best of the lot to open jar files on Android devices. It’s basically a JAVA emulator which you can use to install JAR/JAD/JAVA/J2ME/MIDP apps & games on your Android device.
