Figured it out by adding a loop on startup that waits for media to be
mounted:
private File backgroundToJPG() {
String status = Environment.getExternalStorageState();
if (status.equals(Environment.MEDIA_MOUNTED)) {
File d = new
File(Environment.getExternalStorageDirectory());
d.mkdirs();
File f = new File(d,"/Custom.jpg");
if (!f.exists()){return null;}
return f;
} else {
//keep calling back until media is mounted!
try{
Thread.sleep(1000);
}catch(InterruptedException e){ }
File tmp = backgroundToJPG();
return null;
}
}
