In my application I use a button to launch Camera application and save picture to specific folder on sdCard naming it by current date and time. When I hardcode the name for the picture, it works fine, but if I'm trying to put date in the name it doesn't work at all.

 Intent imageIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
 File imagesFolder = new File(Environment.getExternalStorageDirectory(), Constants.IMAGE_FOLDER_URI);
 Date d = new Date();
 CharSequence s  = DateFormat.format("MM-dd-yy hh:mm:ss", d.getTime());    
 File image = new File(imagesFolder, s.toString() + ".jpg"); //this line doesn't work Uri uriSavedImage = Uri.fromFile(image);
 imageIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);

If I put:

s = "some_name";

then it works, but I need current date and time in image name.

Colon : is not a valid character in a file name, that is why it is failing to create such a file.Try change your name pattern to something like this:

CharSequence s  = DateFormat.format("MM-dd-yy hh-mm-ss", d.getTime());
