Cannot remove an image inserted with MediaStore

I'm saving an image loaded with Picasso to be shared afterwards. This is the code I'm using to save it:
String path = MediaStore.Images.Media.insertImage(
mContext.getContentResolver(), mImageBitmap, "Shared image", null);
return Uri.parse(path);
Now, when the image has been shared, I have to delete it using the URI. I've tried some answers I've seen here but none of them has worked. The image still appears in the gallery. These are the methods I have used:
// Set up the projection (we only need the ID)
String[] projection = { MediaStore.Images.Media._ID };
// Match on the file path
String selection = MediaStore.Images.Media.DATA + " = ?";
String[] selectionArgs = new String[] { new File(mImageUri.toString()).getAbsolutePath() };
// Query for the ID of the media matching the file path
Uri queryUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
ContentResolver contentResolver = getContentResolver();
Cursor c = contentResolver.query(queryUri, projection, selection, selectionArgs, null);
if (c.moveToFirst())
{
// We found the ID. Deleting the item via the content provider will also remove the file
long id = c.getLong(c.getColumnIndexOrThrow(MediaStore.Images.Media._ID));
Uri deleteUri = ContentUris.withAppendedId(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, id);
contentResolver.delete(deleteUri, null, null);
}
c.close();
File file = new File(mImageUri.toString());
// This returns false
file.delete();
context.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(new File(mImageUri.toString()))));
Any idea of what i've done wrong?
Thanks,

Try this for deletion
String[] retCol = { MediaStore.Audio.Media._ID };
Cursor cur = context.getContentResolver().query(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
retCol,
MediaStore.Images.Media.TITLE + "='"+TEMP_FILE_TITLE+"'", null, null
);
try {
if (cur.getCount() == 0) {
return;
}
cur.moveToFirst();
int id = cur.getInt(cur.getColumnIndex(MediaStore.MediaColumns._ID));
Uri uri = ContentUris.withAppendedId(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, id
);
int cnt = context.getContentResolver().delete(uri, null, null);
}finally {
cur.close();
}
In your case replace TEMP_FILE_TITLE = "Shared image"

Set custom sms ringtone for single user

I want to set custom ring while receiving sms from user like "Demo" .Is it possible to set custom ring for single user ? I am trying this but can not achieve my requirement
final Uri lookupUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, "9801205808");
final String[] projection = new String[]{
ContactsContract.Contacts._ID, ContactsContract.Contacts.LOOKUP_KEY
};
final Cursor data = getContentResolver().query(lookupUri, projection, null, null, null);
data.moveToFirst();
try {
final long contactId = data.getLong(0);
final String lookupKey = data.getString(1);
final Uri contactUri = ContactsContract.Contacts.getLookupUri(contactId, lookupKey);
if (contactUri == null) {
return;
}
final String storage = Environment.getExternalStorageDirectory().getPath();
final File file = new File(storage + "/AudioRecorder", "hello.mp4");
final String value = Uri.fromFile(file).toString();
final ContentValues values = new ContentValues(1);
values.put(ContactsContract.Contacts.CUSTOM_RINGTONE, value);
getContentResolver().update(contactUri, values, null, null);
} finally {
data.close();
}

This is what I used to set Ringtone for a contact:
Cursor c =...; // query contact cursor
int dataIndex = c.getColumnIndexOrThrow(Contacts._ID);
String contactId = c.getString(dataIndex);
Uri uri = Uri.withAppendedPath(Contacts.CONTENT_URI, contactId);
ContentValues values = new ContentValues();
values.put(Contacts.CUSTOM_RINGTONE, mRingtoneUri.toString());
getContentResolver().update(uri, values, null, null);

How can I get the song ID from MediaStore if I know the path?

Currently I am getting a song ID from MediaStore by the title of the song:
long id = 0;
ContentResolver cr = context.getContentResolver();
Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
String selection = MediaStore.Audio.Media.TITLE;
String[] selectionArgs = {songTitle};
String[] projection = {MediaStore.Audio.Media._ID};
String sortOrder = MediaStore.Audio.Media.TITLE + " ASC";
Cursor cursor = cr.query(uri, projection, selection, selectionArgs, sortOrder);
if (cursor != null) {
while (cursor.moveToNext()) {
int idIndex = cursor.getColumnIndex(MediaStore.Audio.Media._ID);
id = Long.parseLong(cursor.getString(idIndex));
}
}
return id;
This works good only if the title is not null.
Is there a direct way to get the song ID from MediaStore directly from the path of the mp3 file?

I will answer my own question since I found the solution.
The solution was to replace TITLE with DATA since DATA represents the path of the media file in MediaStore.
public static long getSongIdFromMediaStore(String songPath, Context context) {
long id = 0;
ContentResolver cr = context.getContentResolver();
Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
String selection = MediaStore.Audio.Media.DATA;
String[] selectionArgs = {songPath};
String[] projection = {MediaStore.Audio.Media._ID};
String sortOrder = MediaStore.Audio.Media.TITLE + " ASC";
Cursor cursor = cr.query(uri, projection, selection + "=?", selectionArgs, sortOrder);
Log.d(Constants.LOG_TAG, songPath);
if (cursor != null) {
while (cursor.moveToNext()) {
int idIndex = cursor.getColumnIndex(MediaStore.Audio.Media._ID);
id = Long.parseLong(cursor.getString(idIndex));
}
}
return id;
}

Android: How to get contact DisplayName by contact _ID?

folks!
Look I broke my mind with problem -
how get display_name from ContactContract via _ID I got earlier???
Here is the code:
public static long getId(Context context, String number) {
long id = 0;
String displayName;
// define the columns I want the query to return
final String[] projection = new String[] {
ContactsContract.PhoneLookup.DISPLAY_NAME,
ContactsContract.PhoneLookup._ID};
// encode the phone number and build the filter URI
final Uri contactUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
// query time
final Cursor cursor = context.getContentResolver().query(contactUri, projection, null, null, null);
if(cursor != null) {
if (cursor.moveToFirst()) {
displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));
// HERE IS GOOD _ID!
id = cursor.getLong(cursor.getColumnIndex(ContactsContract.PhoneLookup._ID));
Log.d("_TAG_", displayName);
{
//
// v. N-1
//
Cursor cursor2 = context.getContentResolver().query(
contactUri,
projection,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
new String[]{String.valueOf(id)}, null);
if(cursor2 != null) {
// Cursor valid but string below got error "android.database.CursorIndexOutOfBoundsException: Index -1 requested, with a size of 1 : )"
displayName = cursor2.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));
Log.d("_TAG_", displayName);
}
}
{
//
// v. N
//
Uri myPhoneUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI,
Uri.encode(String.valueOf(id)));
Cursor phoneCursor = context.getContentResolver().query(
myPhoneUri, null, null, null, null);
for (phoneCursor.moveToFirst(); !phoneCursor.isAfterLast(); phoneCursor.moveToNext()) {
// No steps inside!
String str = phoneCursor.getString(phoneCursor
.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Nickname.NAME));
Log.d(App.LOG_TAG, "ContactUtils.getId: " + str);
}
if(phoneCursor != null) {
phoneCursor.close();
}
}
} else {
Log.d("_TAG_", "Contact Not Found # " + number);
}
cursor.close();
}
return id;
}
"v.N-1" and "v.N" are just 2 ones from a million attempts before.
See - I got _ID, so why it doesn't work back as valid query???

Here is decision i found.
public static String getDisplayName(Context context, long id) {
String displayName = null;
// define the columns I want the query to return
final String[] projection = new String[] {
ContactsContract.Contacts.DISPLAY_NAME,
};
final Cursor cursor = context.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, projection,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[] { id + "" }, null);
if(cursor != null) {
if (cursor.moveToFirst()) {
displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
}
cursor.close();
}
return displayName;
}
It works...

Given an Android music playlist name, how can one find the songs in the playlist?

The playlist names can be found by a query on MediaStore.Audio.Playlists.EXTERNAL_CONTENT_URI
and then look at the MediaStore.Audio.PlaylistsColumns.NAME column.
There is a data column too, MediaStore.Audio.PlaylistsColumns._DATA, but it is returning null.
The list of songs (MediaStore.Audio.Media.EXTERNAL_CONTENT_URI/id) do not seem to show any playlist affiliation.

Here is a bit from my program:
The gist is that you need the id for the playlist to grab the songs.
Basically you can take my code and change the where statement to .NAME +" = '"+name+"'",
private Cursor getPlaylists(String playlistId){
Cursor cursor = null;
String[] projection1 = {
MediaStore.Audio.Playlists._ID,
MediaStore.Audio.Playlists.NAME
};
cursor = this.managedQuery(
MediaStore.Audio.Playlists.EXTERNAL_CONTENT_URI,
projection1,
MediaStore.Audio.Playlists._ID+ " = "+playlistId+"",
null,
null);
startManagingCursor(cursor);
cursor.moveToFirst();
playlist_id = cursor.getString(0);
playlist_id2 = cursor.getLong(0);
if(playlist_id2 > 0){
String[] projection = {
MediaStore.Audio.Playlists.Members.AUDIO_ID,
MediaStore.Audio.Playlists.Members.ARTIST,
MediaStore.Audio.Playlists.Members.TITLE,
MediaStore.Audio.Playlists.Members._ID
};
cursor = null;
cursor = this.managedQuery(
MediaStore.Audio.Playlists.Members.getContentUri("external",playlist_id2 ),
projection,
MediaStore.Audio.Media.IS_MUSIC +" != 0 ",
null,
null);
}
cManager(cursor,2,1);
return cursor;
}

Here is a working way to get tracks from a play list. Basically it loops the cursor through all the of the playlist query, and each time it gets the id of a member (track) and using that id of the track we can get other data such as path, artist, duration, album etc.
ContentResolver contentResolver = getContentResolver();
Uri playListUri = MediaStore.Audio.Playlists.Members.getContentUri("external", playlistID); //playlistID is the _ID of the given playlist
MediaMetadataRetriever mr = new MediaMetadataRetriever();
Cursor cursor = contentResolver.query(playListUri, null, null, null, null);
if(cursor != null)
{
if(cursor.moveToNext()) {
do {
String track_id = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Playlists.Members.AUDIO_ID));
Uri mediaContentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
String[] trackProjection = new String[]{MediaStore.Audio.Media.TITLE, MediaStore.Audio.Media.ARTIST, MediaStore.Audio.Media.ALBUM, MediaStore.Audio.Media.DATA};
String selection = MediaStore.Audio.Media._ID + "=?";
String[] selectionArgs = new String[]{"" + track_id};
Cursor mediaCursor = contentResolver.query(mediaContentUri, trackProjection, selection, selectionArgs, null);
if (mediaCursor != null) {
if (mediaCursor.getCount() >= 0) {
mediaCursor.moveToPosition(0);
String song_title = mediaCursor.getString(mediaCursor.getColumnIndex(MediaStore.Audio.Media.TITLE));
String song_artist = mediaCursor.getString(mediaCursor.getColumnIndex(MediaStore.Audio.Media.ALBUM));
String song_album = mediaCursor.getString(mediaCursor.getColumnIndex(MediaStore.Audio.Media.ARTIST));
String song_path = mediaCursor.getString(mediaCursor.getColumnIndex(MediaStore.Audio.Media.DATA));
}
}
} while (cursor.moveToNext());
}
}

this is the way to get all playlist from the device
public ArrayList<String> getPlayList() {
ArrayList<String> arrayList=new ArrayList<String>();
String[] proj = {"*"};
Uri tempPlaylistURI = MediaStore.Audio.Playlists.EXTERNAL_CONTENT_URI;
// In the next line 'this' points to current Activity.
// If you want to use the same code in other java file then activity,
// then use an instance of any activity in place of 'this'.
Cursor playListCursor= activity.managedQuery(tempPlaylistURI, proj, null,null,null);
if(playListCursor == null){
System.out.println("Not having any Playlist on phone --------------");
return arrayList;//don't have list on phone
}
System.gc();
String playListName = null;
System.out.println(">>>>>>> CREATING AND DISPLAYING LIST OF ALL CREATED PLAYLIST <<<<<<");
for(int i = 0; i <playListCursor.getCount() ; i++)
{
playListCursor.moveToPosition(i);
playListName = playListCursor.getString(playListCursor.getColumnIndex("name"));
System.out.println("> " + i + " : " + playListName );
arrayList.add(playListName);
}
if(playListCursor != null)
playListCursor.close();
return arrayList;
}
