Hi Can I add audio to Video in android(Java).
List item Both are in my SD card and merge and give into mp4 format.
Yes, you can. But it will not be so easy,
You need to learn about these api's
MediaExtractor to extract data/track from file.
MediaCodec if you want to encode/decode
MediaMuxer to mux it into mp4 file
You can use all three of them together if you need to or individually.
You can find some example code here.

I want convert video which upload from gallery or camera into GIF image with audio using FFMPEG andorid.Please give me proper solution for create gif image with sound.Please help me
Thanks in adavace
What you are trying to accomplish is impossible.
The .gif format does not support Audio. If you need audio and video in the same file, you should use a container format such as .ogg, .webm, .mkv, or .mp4.

I want to combine two audio files. (A audio file + B audio file = AB audio file)
After searching around, I think the following steps will work
Using an AudioTrack.
Decode PCM from audio files.
Combine PCM.
Are the above steps right, if not, what would be another way to achieve it?
Is there an example and Library source available to look at?
Check Audio Development for Android for information on the subject. Its going to take some research, I do not know much about Android or I would help further.
