How to set ringtone in Android from my activity?

I'm trying to find a way to set a new default ringtone by code from my Android activity.

I have already downloaded the ringtone into a bytearray.

Finally, I managed to set the default ringtone to one that i downloaded. The download code is not included below, only what was needed to set it as default ringtone.

File k = new File(path, "mysong.mp3"); // path is a file to /sdcard/media/ringtone

ContentValues values = new ContentValues();
values.put(MediaStore.MediaColumns.DATA, k.getAbsolutePath());
values.put(MediaStore.MediaColumns.TITLE, "My Song title");
values.put(MediaStore.MediaColumns.SIZE, 215454);
values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3");
values.put(MediaStore.Audio.Media.ARTIST, "Madonna");
values.put(MediaStore.Audio.Media.DURATION, 230);
values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
values.put(MediaStore.Audio.Media.IS_NOTIFICATION, false);
values.put(MediaStore.Audio.Media.IS_ALARM, false);
values.put(MediaStore.Audio.Media.IS_MUSIC, false);

//Insert it into the database
Uri uri = MediaStore.Audio.Media.getContentUriForPath(k.getAbsolutePath());
Uri newUri = this.getContentResolver().insert(uri, values);

RingtoneManager.setActualDefaultRingtoneUri(
  myActivity,
  RingtoneManager.TYPE_RINGTONE,
  newUri
);  

Anyway, I do not totally understand what this code is doing.

The Ringtone manager needs a uri to the file that is to be set as new ringtone. But this uri can not be directly to the sdcard like "/sdcard/media/ringtones/mysong.mp3". That does not work!

What you need is the external file uri of the file which could be something like "/external/audio/media/46"

The 46 is the id of the column in the MediaStore database, so thats why you need to add the sdcard file into the database first.

Anyway, how does mediastore maintain its ids? This number can get really high, as you do this operation many times.

Do i need to delete this row my self? Problem is that some times i dont even controll the deleting of the file since it can be deleted directly from the sdcard with a filebrowser.

Answer By Vidar is too long and it adds duplicate entries every time you want to set a song as ringtone . Instead you should try this

Uri newUri=Uri.parse("content://media/external/audio/media/"+ID);  
try {
      RingtoneManager.setActualDefaultRingtoneUri(context, RingtoneManager.TYPE_RINGTONE, newUri);
    }
catch (Throwable t) {


                  }

public void setRingtone() {
  String ringtoneuri = Environment.getExternalStorageDirectory().getAbsolutePath() + "/media/ringtone";
  File file1 = new File(ringtoneuri);
  file1.mkdirs();
  File newSoundFile = new File(ringtoneuri, "myringtone.mp3");


  Uri mUri = Uri.parse("android.resource://globalapps.funnyringtones/raw/sound_two.mp3");


  ContentResolver mCr = this.getContentResolver();
  AssetFileDescriptor soundFile;
  try {
   soundFile = mCr.openAssetFileDescriptor(mUri, "r");
  } catch (FileNotFoundException e) {
   soundFile = null;
  }

  try {
   byte[] readData = new byte[1024];
   FileInputStream fis = soundFile.createInputStream();
   FileOutputStream fos = new FileOutputStream(newSoundFile);
   int i = fis.read(readData);

   while (i != -1) {
    fos.write(readData, 0, i);
    i = fis.read(readData);
   }

   fos.close();
  } catch (IOException io) {
  }

  ContentValues values = new ContentValues();
  values.put(MediaStore.MediaColumns.DATA, newSoundFile.getAbsolutePath());
  values.put(MediaStore.MediaColumns.TITLE, "my ringtone");
  values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3");
  values.put(MediaStore.MediaColumns.SIZE, newSoundFile.length());
  values.put(MediaStore.Audio.Media.ARTIST, R.string.app_name);
  values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
  values.put(MediaStore.Audio.Media.IS_NOTIFICATION, true);
  values.put(MediaStore.Audio.Media.IS_ALARM, true);
  values.put(MediaStore.Audio.Media.IS_MUSIC, false);

  Uri uri = MediaStore.Audio.Media.getContentUriForPath(newSoundFile.getAbsolutePath());
  Uri newUri = mCr.insert(uri, values);
  try {
   Uri rUri = RingtoneManager.getValidRingtoneUri(this);
   if (rUri != null)
    ringtoneManager.setStopPreviousRingtone(true);
   RingtoneManager.setActualDefaultRingtoneUri(getApplicationContext(), RingtoneManager.TYPE_RINGTONE, newUri);
   Toast.makeText(this, "New Rigntone set", Toast.LENGTH_SHORT).show();
  } catch (Throwable t) {
   Log.e("sanjay in catch", "catch exception"+e.getMessage());
  }

 }

You can use the built-in RingtonePreference class. AndroidGuys has a nice tutorial on this here.
