Android铃声设置错误

Question

点击按钮运行set_ringtone。没有错误，它设置铃声。但是当我第二次点击按钮时，出现错误。

public void set_ringtone(Context context, String ringtone){ 
    File file = new File(Environment.getExternalStorageDirectory(), ringtone + ".mp3"); 
    ContentValues values = new ContentValues(); 
    values.put(MediaStore.MediaColumns.DATA, file.getAbsolutePath()); 
    values.put(MediaStore.MediaColumns.TITLE, ringtone); 
    values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3"); 
    values.put(MediaStore.Audio.AudioColumns.ARTIST, "Halil Öncen"); 
    values.put(MediaStore.Audio.AudioColumns.IS_RINGTONE, true); 
    values.put(MediaStore.Audio.AudioColumns.IS_NOTIFICATION, false); 
    values.put(MediaStore.Audio.AudioColumns.IS_ALARM, false); 
    values.put(MediaStore.Audio.AudioColumns.IS_MUSIC, false); 

    Uri uri = MediaStore.Audio.Media.getContentUriForPath(file.getAbsolutePath()); 
    Uri newUri = context.getContentResolver().insert(uri, values); 
    RingtoneManager.setActualDefaultRingtoneUri(context, RingtoneManager.TYPE_RINGTONE, newUri); 
} 

logcat中，

Answer 1

我认为这个回答可以帮助你SQLiteConstraintException: error code 19: constraint failed when set ringtones

值必须是在SQL数据库中是唯一的。答案中的重要代码类型为：

getContentResolver().delete(uri, MediaStore.MediaColumns.DATA + "=\"" + SDCardRoot + "\"", null);
