How to search for contacts in android with partial phone number

I am trying to do fuzzy search of contacts in my android application with partial phone number, with below code. But my search function always ends in no result.
For example,
I have contact with phone number 1234567890 with name as "example".
fuzzySearch("4567"); should have return with contact named "example".
Can some please point me where am I wrong? I have checked here. But ended in run-time sql query error.
public ArrayList<Contact> fuzzySearch(String match) {
private static final String SELECTION = Phone.NUMBER + " LIKE ? COLLATE NOCASE";
Uri uri = Uri.withAppendedPath(ContactsContract.CommonDataKinds.Phone.CONTENT_FILTER_URI, Uri.encode(match));
String[] projectionFields = new String[]{ContactsContract.Contacts._ID, Phone.NUMBER};
CursorLoader cursorLoader = null;
ArrayList<Contact> listContacts = new ArrayList<>();
if(match.trim().length() == 0){
return listContacts;
}else {
cursorLoader = new CursorLoader(context, uri, projectionFields, SELECTION, new String[]{"%"+match+"%"}, Phone.NUMBER);
}
Cursor c = cursorLoader.loadInBackground();
final Map<String, Contact> contactsMap = new HashMap<>(c.getCount());
if (c.moveToFirst()) {
int idIndex = c.getColumnIndex(ContactsContract.Contacts._ID);
int nameIndex = c.getColumnIndex(Phone.NUMBER);
do {
String contactId = c.getString(idIndex);
String contactDisplayName = c.getString(nameIndex);
Contact contact = new Contact(contactId, contactDisplayName);
contactsMap.put(contactId, contact);
listContacts.add(contact);
} while (c.moveToNext());
}
c.close();
return listContacts;
}

use PhoneLookup instead of phone.
because you already encode the search key into the URL, you don't need SELECTION, remove it.
Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(match));
Cursor cur = resolver.query(uri, new String[]{PhoneLookup.DISPLAY_NAME,PhoneLookup.NUMBER, PhoneLookup.CONTACT_ID}, null, null, null);

How to get songs and other media from an Album ID?

I want to get songs and other MEDIA details from Album Id. All I have is Album Id and I tried many solutions but none of them succeed.
My code snippet:
ContentResolver contentResolver = getContentResolver();
Uri mediaUri = ContentUris.withAppendedId(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, albumId);
Log.wtf("SKJDBKJ", mediaUri.toString());
Cursor mediaCursor = contentResolver.query(mediaUri, null, null, null, null);
// if the cursor is null.
if(mediaCursor != null && mediaCursor.moveToFirst())
{
Log.wtf("DSJK", "entered cursor");
//get Columns
int titleColumn = mediaCursor.getColumnIndex(MediaStore.Audio.Albums.ALBUM);
int idColumn = mediaCursor.getColumnIndex(MediaStore.Audio.Media._ID);
int artistColumn = mediaCursor.getColumnIndex(MediaStore.Audio.Media.ARTIST);
// Store the title, id and artist name in Song Array list.
do
{
long thisId = mediaCursor.getLong(idColumn);
String thisTitle = mediaCursor.getString(titleColumn);
String thisArtist = mediaCursor.getString(artistColumn);
Log.wtf("Title", thisTitle);
// Add the info to our array.
songArrayList.add(new Song(thisId, thisTitle, thisArtist));
}
while (mediaCursor.moveToNext());
// For best practices, close the cursor after use.
mediaCursor.close();
}
Log for mediaUri returns path to current album, e.g. : content://media/external/audio/media/41.
Someone tell me how do I do it?

I have done it by myself.You can write simple sqlite query for 'selection' string on contentResolver.query .This example can show you how to get songs by album Id. I think this is best way.
ArrayList<Song> songs = new ArrayList<>();
String selection = "is_music != 0";
if (albumId > 0) {
selection = selection + " and album_id = " + albumId;
}
String[] projection = {
MediaStore.Audio.Media.TITLE,
MediaStore.Audio.Media.ARTIST,
MediaStore.Audio.Media.DATA,
MediaStore.Audio.Media.DISPLAY_NAME,
MediaStore.Audio.Media.DURATION,
MediaStore.Audio.Media.ALBUM,
MediaStore.Audio.Media.ALBUM_ID
};
final String sortOrder = MediaStore.Audio.AudioColumns.TITLE + " COLLATE LOCALIZED ASC";
Cursor cursor = null;
try {
Uri uri = android.provider.MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
cursor = getActivity().getContentResolver().query(uri, projection, selection, null, sortOrder);
if (cursor != null) {
cursor.moveToFirst();
int position = 1;
while (!cursor.isAfterLast()) {
Song song = new Song();
song.setTitle(cursor.getString(0));
song.setDuration(cursor.getLong(4));
song.setArtist(cursor.getString(1));
song.setPath(cursor.getString(2));
song.setPosition(position);
song.setAlbumId(cursor.getLong(6));
cursor.moveToNext();
}
}
} catch (Exception e) {
Log.e("Media", e.toString());
} finally {
if (cursor != null) {
cursor.close();
}
}

I have figured it out myself after a LOT of trial and errors. I don't know if it's the best and safest way to do so, but as far as it's working I am happy.
I changed my code a bit and compared Album IDs. Here's the snippet:
ContentResolver contentResolver = getContentResolver();
Uri mediaUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
Log.wtf("SKJDBKJ", mediaUri.toString());
Cursor mediaCursor = contentResolver.query(mediaUri, null, null, null, null);
// if the cursor is null.
if(mediaCursor != null && mediaCursor.moveToFirst())
{
Log.wtf("DSJK", "entered cursor");
//get Columns
int titleColumn = mediaCursor.getColumnIndex(MediaStore.Audio.Media.TITLE);
int idColumn = mediaCursor.getColumnIndex(MediaStore.Audio.Media._ID);
int artistColumn = mediaCursor.getColumnIndex(MediaStore.Audio.Media.ARTIST);
int albumId = mediaCursor.getColumnIndex(MediaStore.Audio.Media.ALBUM_ID);
// Store the title, id and artist name in Song Array list.
do
{
long thisId = mediaCursor.getLong(idColumn);
long thisalbumId = mediaCursor.getLong(albumId);
String thisTitle = mediaCursor.getString(titleColumn);
String thisArtist = mediaCursor.getString(artistColumn);
// Add the info to our array.
if(this.albumId == thisalbumId)
{
Log.wtf("SAME2SAME", String.valueOf(thisalbumId));
Log.wtf("SAME2SAME", String.valueOf(this.albumId));
songArrayList.add(new Song(thisId, thisTitle, thisArtist));
}
}
while (mediaCursor.moveToNext());
// For best practices, close the cursor after use.
mediaCursor.close();
}
I changed:
Albums to Media in MediaStore.Audio.Audio.xxx.
Got the album Id of Media.
Compared that to album Id I receive from bundle extras.
Only add those songs in the arrayList.
I guess this'll be the way for Artists too.

when you put the cursor.movenext function in to the while loop, the first line of
MediaStore database will be passed without saving the data because the function move the cursor and then check so its better to make a value instead of putting the movenext function into the while.
try {
Projection = new String[]{
MediaStore.Audio.Media.TITLE, MediaStore.Audio.Media.ALBUM
, MediaStore.Audio.Media.ARTIST,MediaStore.Audio.Media.DATA, MediaStore.Audio.Media.SIZE};
Cursor cursor = getContentResolver().query(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, Projection, null, null, null);
cursor.moveToFirst();
for (int i = 0; i < 5; i++) {
columns[i] = cursor.getColumnIndex(Projection[i]);
}
Music tempMusic = new Music();
while (next) {
tempMusic.setName(cursor.getString(columns[0]));
tempMusic.setAlbum(cursor.getString(columns[1]));
tempMusic.setArtist(cursor.getString(columns[2]));
tempMusic.setUri(cursor.getString(columns[3]));
tempMusic.setSize(cursor.getDouble(columns[4]));
if(!cursor.moveToNext())
{
next=false;
}
musicss.add(tempMusic);
tempMusic = new Music();
}

public Bitmap getAlbumArt(Long albumId) {
Bitmap albumArt = null;
try {
final Uri AlbumArtUri = Uri.parse("content://media/external/audio/albumart");
Uri uri = ContentUris.withAppendedId(AlbumArtUri, albumId);
ParcelFileDescriptor pfd = GlobalSongList.getInstance().getContentResolver().openFileDescriptor(uri, "r");
if (pfd != null) {
FileDescriptor fd = pfd.getFileDescriptor();
albumArt = BitmapFactory.decodeFileDescriptor(fd);
}
} catch (Exception e) {
}
return albumArt;
}
ALBUM_ID is a field in the MediaStore and you can query it in the same way you query for title,artist,etc.
public Long getAlbumId(String id)
{
Cursor musicCursor;
String[] mProjection = {MediaStore.Audio.Media._ID, MediaStore.Audio.Media.ALBUM_ID};
String[] mArgs = {id};
musicCursor = musicResolver.query(musicUri, mProjection, MediaStore.Audio.Media._ID + " = ?", mArgs, null);
musicCursor.moveToFirst();
Long albumId=musicCursor.getLong(musicCursor.getColumnIndex(MediaStore.Audio.Media.ALBUM_ID));
return albumId;
}

This is how I did.
Works perfect.
String selection= MediaStore.Audio.Media.IS_MUSIC+"!=0";
String[] projection={
MediaStore.Audio.Media._ID,
MediaStore.Audio.Media.DATA,
MediaStore.Audio.Media.TITLE,
MediaStore.Audio.Media.ARTIST,
MediaStore.Audio.Media.ALBUM,
MediaStore.Audio.Albums.ALBUM_ID,
MediaStore.Audio.Media.DURATION
};
Cursor cursor=getActivity().managedQuery(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,projection,selection,null,"title asc");
List<String> data=new ArrayList<>();
List<String> songs=new ArrayList<>();
List<String> artists=new ArrayList<>();
List<String> albums=new ArrayList<>();
List<String> album_id=new ArrayList<>();
List<String> durations=new ArrayList<>();
cursor.moveToFirst();
while (cursor.moveToNext()){
if(cursor.getString(5).equals(mAlbumId)) {
data.add(cursor.getString(1));
songs.add(cursor.getString(2));
artists.add(cursor.getString(3));
albums.add(cursor.getString(4));
album_id.add(mAlbumId);
durations.add(cursor.getString(6));
}
}

Getting name and email from contact list is very slow

I'm implementing an AutoCompleteTextView and I need Name and E-Mail of all my contacts.
I found this snippet that I'm running asynchronously but it's very slow.
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
Cursor emailCur = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?", new String[]{id}, null);
while (emailCur.moveToNext()) {
String email = emailCur.getString(emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
autoCompleteAdapter.add(name + " - " + email);
}
emailCur.close();
}
}
}
I'm performing a sort of inner query and I think that's the problem. Is there a way to tune it and make it faster?

private static final String[] PROJECTION = new String[] {
ContactsContract.CommonDataKinds.Email.CONTACT_ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Email.DATA
};
...
ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, PROJECTION, null, null, null);
if (cursor != null) {
try {
final int contactIdIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.CONTACT_ID);
final int displayNameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
final int emailIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA);
long contactId;
String displayName, address;
while (cursor.moveToNext()) {
contactId = cursor.getLong(contactIdIndex);
displayName = cursor.getString(displayNameIndex);
address = cursor.getString(emailIndex);
...
}
} finally {
cursor.close();
}
}
few notes:
use just ContactsContract.CommonDataKinds.Email.CONTENT_URI to get information you need, see ContactsContract.CommonDataKinds.Email for information what columns you can query
use projection to get only those columns you really need, you save some memory and increase query performance
get column indexes only once, just before the while cycle

You should not query directly the ContactsContract.Contacts
Make just one query on the ContactsContract.CommonDataKinds with the email data kind.
The ContactsContract.CommonDataKinds.Email inherits a lot of other interfaces that you can use to build your projection. (see inherited constants from the documentation)
For example :
import android.provider.ContactsContract.CommonDataKinds.Email;
[...]
public static final String[] EMAILS_PROJECTION = new String[] {
Email._ID,
Email.DISPLAY_NAME_PRIMARY,
Email.ADDRESS
};
to be used with the
Email.CONTENT_URI
You can retrieve a lot of information (such as user id, user display name ...) directly from the email data kind.
EDIT:
I just realized you're trying to build an AutoCompleteTextView.
You should override the runQueryOnBackgroundThread method and the convertToString of your CursorAdapter and use the Email.CONTENT_FILTER_URI
I really strongly suggest you to take a look at the ApiDemo samples.
Especially the AutoComplete4.java sample that you can find HERE.

ContentResolver cr = mContext.getContentResolver();
Cursor cursor = mContext.getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, PROJECTION, "HAS_PHONE_NUMBER <> 0", null, null);
if (cursor!= null)
{
final int displayNameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
final int numberIndex = cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER);
final int idIndex= cursor.getColumnIndex(ContactsContract.Contacts._ID);
String displayName, number = null, idValue;
while (cursor.moveToNext())
{
displayName = cursor.getString(displayNameIndex);
idValue= cursor.getString(idIndex);
Cursor phones = mContext.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, "contact_id = '" + idValue + "'", null, null);
phones.moveToFirst();
try
{
number = phones.getString(phones.getColumnIndex("data1"));
}
catch (CursorIndexOutOfBoundsException e)
{
}
phones.close();
userList.add(new ContactModel(displayName, number, null));
}
}

How to get contact name from number using like in selection in android

Here is the code which iam using
private String getContactNameFromNumber(String number) {
// define the columns I want the query to return
String[] projection = new String[] {
Contacts.Phones.DISPLAY_NAME,
Contacts.Phones.NUMBER };
// encode the phone number and build the filter URI
Uri contactUri = Uri.withAppendedPath(Contacts.Phones.CONTENT_FILTER_URL, Uri.encode(number));
// query time
Cursor c = getContentResolver().query(contactUri, projection, null,
null, null);
// if the query returns 1 or more results
// return the first result
if (c.moveToFirst()) {
String name = c.getString(c
.getColumnIndex(Contacts.Phones.DISPLAY_NAME));
return name;
}
// return the original number if no match was found
return number;
}
but this code returns only number exactly equal to contact number.
i want to use like statement so that even last 7 numbers matches i should be able to get the name..
how to write that..?

Retrieving Name from Phones Contacts using Phone Number
private String getContactNameFromNumber(String number) {

if (cursor.moveToFirst())
{
name = cursor.getString(cursor.getColumnIndex(PhoneLookup.DISPLAY_NAME));
}
return name;
//proceed as you need
}

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;
}
