Hello my friend, I saw you have 130$ budget but at this budget I cant do this app, if you want this app developed I can do it in 25 day and 550 USD, just consider my offer, thanks in advance
Assalam ul alakam sir hope you are fine .. I am an android developer and can made this app easily ... Basically some of its concepts are used widely in my previous app like video decoding formate extraction and other things... I will tell you the truth i am not good in design part but i will give you back end functionality very power full.. Thanks anyways have a good day ..
What I understand from the description is you need a simple app to convert phone media to mp3.
I am familiar with all UI components for the app mentioned in the link. For backend video converting we need to use android media codec (or some other library ) to extract audio data and embed meta data by user. I have some idea to proceed but things will be more clarified after we proceed.
