Unfortunately, there is no simple way to make an application like you need. The source code will be huge, so I can give you a description of an algorithm and some useful links.
Video: You need to record a video using the camera 2 api and Surface. This Surface should be gotten from MediaCodec (encoder). The MediaCodec (encoder) will encode video frames from a camera and convert them into ByteBuffers.
Audio: You need to extract an audio from your raw file using MediaExtractor which will extract audio samples as ByteBuffers.
Muxing: Both, audio samples (ByteBuffers) and video frames (ByteBuffers) should be muxed using MediaMuxer.
