i'm java developer but new to android , i want to build an application which do the following :
1. select a start and end date , select start and end time , then select a sound file to be played when the start date and time come.
2. can copy what i did in the previous step to another date.
3. this application must be running in the background with an icon in the notification bar.
4. this application will be in the start up applications as soon as the device turned on it will run automatically
i'm little confused from where to start, any recommendations ?
