i'll expain what i mean to do. What i want is to share my phone (each file) and my computer (each file) with each other (this app would be for one owner) just like we use onedrive, we will have a system folder in our pc called my phone, which will show files of my phone when they are connected together or both are connected to a wifi. Same for the phone, ill be able to view my files online and will be able to save files offline when pc and phone are connected. Its somewhat what teamviewer does, but its for one owner so you wont have to login again and again. Now i want the file transfer to happen via ftp. So am i clear with what i want? Now my question is, what will i have to learn for this? And what technologies will be used in making of this
