Question

I’d like to:

1. Generate a random number (easy enough)
2. take that random number and add it to some sort of dynamic path
3. use the dynamic path in the mediaplayer creation.

E.g.

Resource folder(raw) contains
1.mp3
2.mp3
3.mp3

Random number generates a number between 0 and 4

e.g: 2

Inserts random number to path

E.g. a String?

String PATH = "R.raw." + RANDOM-NUMBER

MediaPlayer mp = MediaPlayer.create(context, PATH);

However, of course MediaPlayer uses a URI variable not a string, i did try

myUri = Uri.parse("R.raw.2"); 

but get a nullPointerException

I imagine this is very simple/straight forward to answer and my knowledge simply evades me

Thanks very much

You cant do that with resources. Here’s how I see you’d go about it.

int randomInt = generateRandomInt(), id;
switch (randomInt) {
case 1:
    id = R.raw.1;
    break;
case 2:
    id = R.raw.2;
    break;
...
}
setDataFromResource(getResources(), myMediaPlayer, id);

AFAIK, you have to use setDataFromResource to set the data for your media player from R.raw
