Correcting the existing coding and add new options (Exclusively for DreamHawkers)

I have downloaded an android music player source code from github and asked a freelancer to add folder view of songs for the player and ability to play songs from folder view. They have implemented the folder view but when we select the songs in the folders, the song is going to media player and starts playing instead of using the music service in the app iteself. The song shall be played in the app itself instead of media player so that we can control (play, stop, forward, etc.)the song from appCan you please help me to correct it i will send you the drop box link In addition to this , each song in folder view shall have the following options in the menu similary to the songs in the song list 1. Play 2. Play Next 3. Go to Artist 4. Go to Album 5. Add to Playlist 6. Add to Queue Payment Terms shall be like this; 1. I will create first milestone (half amount)as soon as I award the project. 2. I will release the milestone as soon as I receive the completed apk 3. I will create the second and final milestone as soon as I receive the completed apk 4. I will release the second milestone after receiving the coding. 5. I will write 5 star review for you after checking the coding. Freelancers who agreed to the above payment terms only need to bid.
