How to get Uri from MediaStore via file path?

Question

In my program, I want to save the selected ringtone by its path to the file, and then set it as the current ringtone later.

I have a uri ringtone from RingtonePreference and get the path to it from the MediaStore database.

eg.

  Uri - content: // media / internal / audio / media / 29
 Path - /system/media/audio/notifications/Ascend.mp3

Now, how do I get the Uri ringtone from the file path that I saved?

Since the ringtone already exists in MediaStore, I tried the following functions, but it does not work.

  uriRingtone = MediaStore.Audio.Media.getContentUriForPath (szRingtonePath);

Uri is not the same as what I got from RingtonePreference.

  uriRingtone - content: // media / internal / audio / media

How do I request MediaStore to get the Uri I need?

ps the reason why I don’t store the Uri ringtone directly is because I found that the Uri for the same ringtone can sometimes change on some device.

How can you restore the ringtone URIs stored in RingtonePreference (as far as I know), knowing the name of the song. Then you can query it with the cursor to get the _id ringtone, and with it you can create a URI:

String ringtoneTitle = "<The desired ringtone title>"; Uri parcialUri = Uri.parse("content://media/external/audio/media"); // also can be "content://media/internal/audio/media", depends on your needs Uri finalSuccessfulUri; RingtoneManager rm = new RingtoneManager(getApplicationContext()); Cursor cursor = rm.getCursor(); cursor.moveToFirst(); while(!cursor.isAfterLast()) { if(ringtoneTitle.compareToIgnoreCase(cursor.getString(cursor.getColumnIndex(MediaStore.MediaColumns.TITLE))) == 0) { int ringtoneID = cursor.getInt(cursor.getColumnIndex(MediaStore.MediaColumns._ID)); finalSuccessfulUri = Uri.withAppendedPath(parcialUri, "" + ringtoneID ); break; } cursor.moveToNext(); } 

where finalSuccessful uri is the uri pointing to the ringtone in RingtonePreference.

You can also do this in a more universal way for any content in MediaStore. I have to get the path from the URI and get the URI from the paths. First:

 /** * Gets the corresponding path to a file from the given content:// URI * @param selectedVideoUri The content:// URI to find the file path from * @param contentResolver The content resolver to use to perform the query. * @return the file path as a string */ private String getFilePathFromContentUri(Uri selectedVideoUri, ContentResolver contentResolver) { String filePath; String[] filePathColumn = {MediaColumns.DATA}; Cursor cursor = contentResolver.query(selectedVideoUri, filePathColumn, null, null, null); cursor.moveToFirst(); int columnIndex = cursor.getColumnIndex(filePathColumn[0]); filePath = cursor.getString(columnIndex); cursor.close(); return filePath; } 

The latter (which I do for video, but can also be used for audio or files or other types of stored content, replacing MediaStore.Audio (etc.) for MediaStore.Video:

 /** * Gets the MediaStore video ID of a given file on external storage * @param filePath The path (on external storage) of the file to resolve the ID of * @param contentResolver The content resolver to use to perform the query. * @return the video ID as a long */ private long getVideoIdFromFilePath(String filePath, ContentResolver contentResolver) { long videoId; Log.d(TAG,"Loading file " + filePath); // This returns us content://media/external/videos/media (or something like that) // I pass in "external" because that the MediaStore name for the external // storage on my device (the other possibility is "internal") Uri videosUri = MediaStore.Video.Media.getContentUri("external"); Log.d(TAG,"videosUri = " + videosUri.toString()); String[] projection = {MediaStore.Video.VideoColumns._ID}; // TODO This will break if we have no matching item in the MediaStore. Cursor cursor = contentResolver.query(videosUri, projection, MediaStore.Video.VideoColumns.DATA + " LIKE ?", new String[] { filePath }, null); cursor.moveToFirst(); int columnIndex = cursor.getColumnIndex(projection[0]); videoId = cursor.getLong(columnIndex); Log.d(TAG,"Video ID is " + videoId); cursor.close(); return videoId; } 

Basically, the DATA MediaStore column (or any subsector you request) saves the file path, so you use this information to search.

The following code will return the absolute path for the Uri content of audio, video, and image.

 public static String getRealPathFromURI(Context context, Uri contentUri) { Cursor cursor = context.getContentResolver().query(contentUri, null, null, null, null); int idx; if(contentUri.getPath().startsWith("/external/image") || contentUri.getPath().startsWith("/internal/image")) { idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA); } else if(contentUri.getPath().startsWith("/external/video") || contentUri.getPath().startsWith("/internal/video")) { idx = cursor.getColumnIndex(MediaStore.Video.VideoColumns.DATA); } else if(contentUri.getPath().startsWith("/external/audio") || contentUri.getPath().startsWith("/internal/audio")) { idx = cursor.getColumnIndex(MediaStore.Audio.AudioColumns.DATA); } else{ return contentUri.getPath(); } if(cursor != null && cursor.moveToFirst()) { return cursor.getString(idx); } return null; }

@ dong221: Use internal URI as MediaStore.Audio.Media.INTERNAL_CONTENT_URI.
