Dialing with Intent.ACTION_CALL stopps at # in phone number

I try to dial the phone number 03012345,1234,#31#,98765 (callthrough with a FRITZ!Box)

"03012345" is the phone number of the FRITZ!Box, "," are dial pauses, "#31#" is a prefix to show my own phone number to the callee and "98765" is the phonenumber of the开发者_运维百科 callee.

String phonenumber = "03012345,1234,#31#,98765";
startActivity(new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + phonenumber)));

On my smartphone, everything works fine, but some user reported to me, that their smartphones stopp dialing after the first #. But when they dial from contacts, it works.

Maybe, Uri.parse splits the phone number? Or is there another way to dial such a phone number?

Here is the solution:

String phonenumber = "03012345,1234,#31#,98765"; // , = pauses
encodedPhonenumber = URLEncoder.encode(phonenumber, "UTF-8");
startActivity(new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + encodedPhonenumber)));

You simply have to encode the phone number.

Really late on the answer, but another way that this can be done is with Uri.Builder. Using encodedPath() assumes that the string you're passing is already encoded, so it will be added to the Uri as is:

final String phonenumber = "03012345,1234,#31#,98765";
final Uri uri = new Uri.Builder().scheme("tel").encodedPath(phonenumber).build();
startActivity(new Intent(Intent.ACTION_CALL, uri));
