I have a directory of .mp3 files on a web server. Also in that directory is a text file named "mp3.txt" (all lower case)
The web server URL and directory name are static. The contents of mp3.txt may change at any time.
The finished app in (distributed in .apk format) has one button "Download Promo Album" and one checkbox "Save to SD Card". When the button is pressed the app goes to the specific URL, downloads and reads the mp3.txt text file, and then downloads each individual .mp3 file listed in the text file and puts it on the Android device where any Music app the user has can find it on either the device or the SD card as selected by the user.
Example of mp3.txt:
That mp3 file exists at http://www.All-Con.net/spacecity/mp3 ... which is where those .mp3 files also reside.
So when the button is pushed, the app goes to http://www.All-Con.net/spacecity/mp3 , reads the mp3.txt file and then downloads all of the files from that same directory to the location on the Android device.
A nice little text line "Now downloading..." with the current file name would be great if you can work it in with "Done!" when it is completed. Once the app is done, it should end and not keep running in memory.
When I modify the mp3.txt file, the app will look for whatever files are listed in it at that time if the user pushes the button again. THIS APP DOES NOT AUTO-UPDATE when the mp3.txt changes.
Our logo needs to be on the app's form and can be used for the icon with the app name "Demo Album".
This should be a very EASY app for you to write. We will distribute it. No need to go through Google Play Store.
