I have found one android call recorder application, This application facilitates you with an option of auto upload which allows you to mechanically upload files on server, including Google drive, Dropbox, Gmail inbox, Evernote and sound loud. For this, you need to enable 3 options from the default setting menu which allows you to store files automatically. This option makes expedient for users to access files afterwards. Also, this application has the ability to record files in different formats like WAV, 3GPP, AMR, MP4 & MP3.
