Conversion of apk files to mp4 file format

APK files are installation packages for Google Android mobile OS and it is unlikely that these can be directly converted to MP4 multimedia files with some simple converter, which means that apk to mp4 conversion is likely not possible. However, sometimes you can find odd apps that basically playback a single video and are distributed as .apk files. Such package usually contains simple player (or instructions) and the video itself.
