I have developed a sound board application, in which I set ringtones on long press. No issues about it. The ringtone is changed. But when i go to Settings->Sound & Display->Phone Ringtone my ringtone is not listed at all. And No ringtone is selected. How do I list my ringtone there?
The list of ringtones is pulled from the system ringtones directory, as well as from the SD Card, if it contains a folder named "ringtones". So what you may try doing is to also copy the ringtone from your soundboard to the SD Card, into a folder called "ringtones" (first perform a check to see if the folder already exists) at the same time that you set the ringtone.
