How to overlay audio over video in android?

How do I merge or combine audio in an .mp4 video on Android?

• In my Android application I am recording .mp4 h264 encoded video using MediaRecorder and setting the quality of CamcorderProfile.But their is only two option CamcorderProfile.http://developer.android.com/reference/android/media/CamcorderProfile.html#QUALITY_LOW and CamcorderProfile.http://developer.android.com/reference/android/media/CamcorderProfile.html#QUALITY_HIGH is working to record low and high quality video respectively. Low quality video is very low quality pixlated with around 300 kb size and High quality video is very high quality with more than 10 mb size.Other CamcorderProfile options like http://developer.android.com/reference/android/media/CamcorderProfile.html#QUALITY_QVGA , http://developer.android.com/reference/android/media/CamcorderProfile.html#QUALITY_720P,http://developer.android.com/reference/android/media/CamcorderProfile.html#QUALITY_480P etc is not working and application crashes. How can I record medium qulality video using  CamcorderProfile and having size less than 1 mb.After recording my requirement is to remove audio from recorded video and combine/merge a audio selected from user music files.
