I have a Music player project in Android Studio, and I need to get all music from the device.
But somehow this.getContentResolver().query(); is not getting any music from my device.
In the logcat there is no log, and if I debug the app before the while loop and after it(because it does not enter in the while loop) it says that the cursor does not have any row(mCount = 0)
Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
ContentResolver resolver = this.getContentResolver();
String[] projection = {
MediaStore.Audio.Media.ALBUM,
MediaStore.Audio.Media.DATA,
MediaStore.Audio.Media.TITLE,
MediaStore.Audio.Media.ARTIST
};
String where = MediaStore.Audio.Media.IS_MUSIC + " != 0";
Cursor c = resolver.query(uri, projection, where, null, null);
if (c != null) {
while (c.moveToNext()) {
String path = c.getString(0);
String name = c.getString(1);
String album = c.getString(2);
String artist = c.getString(3);
Log.e("Name :" + name, " Album :" + album);
Log.e("Path :" + path, " Artist :" + artist);
}
c.close();
}

I was trying to get buckets having audio files using MediaStore. This is working fine on Android 10 API 29 but not working previous Android versions. I've attached a screenshot of working example on Android 10 API 29.

The reason of the exception is BUCKET_DISPLAY_NAME. It is added in API 29. Before this we were using DISPLAY_NAME for API 28 & below. Please refer to the docs BUCKET_DISPLAY_NAME.
For solution you can write conditions according to current API level. And for getting folder name, you can use RELATIVE_PATH.
In API verions <= 28 BUCKET_DISPLAY_NAME only exists for images and videos, so, accesible via MediaStore.Images.ImageColumns.BUCKET_DISPLAY_NAME or MediaStore.Vidos.VideoColumns.BUCKET_DISPLAY_NAME.
That said, the solution to get the BUCKET_DISPLAY_NAME for audios in versions bellow 29, is to parse the MediaStore.Files.FileColumns.DATA. This field is deprecated in 29, but still valid in previous versions.
The field contains the actual path + filename, and since a BUCKET_DISPLAY_NAME is in reality the actual parent folder name where a file is located, what you need to do is to remove the file name, and then get the sub-string starting at the last found backward-slash from the path.
I did it my self now. First retrieved all audio files, then separated audio URIs. From audio URIs, I've got Folder Names. I'm posting my solution here so maybe someone else can get benefit from it.

I have this code that want to extract all thumbnails but the array result is empty and logically list bitmaps too.Where path is "/emulated/storage/legacy", context is the Activity and the query is with condition. Any Idea? Thanks.
public void getThubmnails() {
String[] cols = {
MediaStore.Files.FileColumns._ID,
MediaStore.Files.FileColumns.DATA,
MediaStore.Files.FileColumns.DATE_ADDED,
MediaStore.Files.FileColumns.MEDIA_TYPE,
MediaStore.Files.FileColumns.MIME_TYPE,
MediaStore.Files.FileColumns.DISPLAY_NAME
};
Uri uri = MediaStore.Files.getContentUri("external");
Cursor cursor = this.context.getContentResolver().query(
uri,
cols,
MediaStore.Files.FileColumns.DATA + "=?",
new String[] {
path,
},
null
);
cursor.moveToFirst();
int index = cursor.getColumnIndexOrThrow(MediaStore.Files.FileColumns._ID);
int name = cursor.getColumnIndexOrThrow(MediaStore.Files.FileColumns.DISPLAY_NAME);
int tipo = cursor.getColumnIndexOrThrow(MediaStore.Files.FileColumns.MIME_TYPE);
int path = cursor.getColumnIndexOrThrow(MediaStore.Files.FileColumns.DATA);
String[] result = new String[cursor.getCount()];
while(cursor.moveToNext()) {
result[cursor.getPosition()] = "ID: " + String.valueOf(cursor.getLong(index))
+ " " + "NAME: " + cursor.getString(name)

I am trying to retrieve contacts from my phone that has only numbers and put them into an arrayList, view them in lazy adapter and on click of name I would like show only numbers. I managed to get the list of contacts and numbers but the problem is when I have a contact with multiple numbers it just adds up into the list.
Something like for e.g
David +1 508 656 9043
David +1 403 604 7053
David +1 212 608 7053
Instead I would like to show only David in the list and when I click it should show all the three numbers.
I tried this:
void getContactNumbers()
{
ContentResolver cr = getContentResolver();
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME+ " COLLATE LOCALIZED ASC";
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, sortOrder);
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));
Log.e("contact", "...Contact Name ...." + name);
if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0)
{
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
new String[]{id}, null);
while (pCur.moveToNext())
{
String phoneNo = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
Log.e("contact", "...Contact Name ...." + name + "...contact Number..." + phoneNo);
}
pCur.close();
}
}
}
}
How to solve this part?
Thanks!
Thanks Harshid. There was selection change instead of IN_VISIBLE_GROUP + " = '1'"; -
I added HAS_PHONE_NUMBER + " = '1'";
All contacts came up.. Hope the below code helps others!!
Thanks!
final Uri uri = ContactsContract.Contacts.CONTENT_URI;
final String[] projection = new String[] {
ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts.PHOTO_ID
};
String selection = ContactsContract.Contacts.HAS_PHONE_NUMBER + " = '1'";
final String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";
Cursor cur = getContentResolver().query(uri, projection, selection, null, sortOrder);
if (cur.getCount() > 0)
{
while (cur.moveToNext())
{
String Sid = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
Log.e("contact", "...Contact Name ...." + name);
// get the phone number
Cursor pCur = getApplicationContext().getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?", new String[] { id }, null);
while (pCur.moveToNext()) {
number = pCur.getString(pCur .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
pCur.close();
}
}
cur.close();
You have to this way query and get contact with multiple number.
final Uri uri = ContactsContract.Contacts.CONTENT_URI;
final String[] projection = new String[] {
ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts.PHOTO_URI
};
String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '1'";
String[] selectionArgs = null;
final String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";
Cursor cur = getContentResolver().query(uri, projection, selection, selectionArgs, sortOrder);
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));
Log.e("contact", "...Contact Name ...." + name);
// get the phone number
Cursor pCur = getApplicationContext().getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?", new String[] { id }, null);
while (pCur.moveToNext()) {
number = pCur.getString(pCur .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
pCur.close();
}
}
cur.close();
Try this code if getting error then put comment otherwise enjoy..
i'm trying to read contacts with this code but it only gets Contacts but not contacts data.Please
tell me am i going on a wrong path or what is wrong with this.
Cursor contacts = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
while(contacts.moveToNext()) {
int contactIdColumnIndex = contacts.getColumnIndex(ContactsContract.Contacts._ID);
long contactId = contacts.getLong(contactIdColumnIndex);
System.out.println(contactId);
Cursor c = getContentResolver().query(Data.CONTENT_URI,
new String[] {Data._ID, Phone.NUMBER, Phone.TYPE},
Data.CONTACT_ID + "=?" + " AND "
+ Data.MIMETYPE + "='" + Phone.CONTENT_ITEM_TYPE + "'",
new String[] {String.valueOf(contactId)}, null);
//retrieving data
while(c.moveToNext()){
long Id=c.getLong(0);
String number=c.getString(1);
String type=c.getString(2);
String name=c.getString(3);
System.out.println(Id);
System.out.println(number);
System.out.println(type);
System.out.println(name);
}
c.close();
}
contacts.close();
This runs well when i debug this and it only print ContactIds only
1
2
3
4
but no data...(apologize for long question)
try this code
String number = "";
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));
if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER},
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
new String[]{id}, null);
while (pCur.moveToNext()) {
for(int i=0;i<pCur.getColumnCount();i++)
number = pCur.getString(i);
}
pCur.close();
pCur = null;
}
}
}
cur.close();
cur = null;
cr = null;
Hi
I have a problem in displaying the contacts image in android.
Following is the code snippet I have used,
public String getCallersInfo(ContentResolver cnt,String phoneNumber)
{
mContentResolver = cnt;
lNumber = phoneNumber;
System.out.println("Start test");
Cursor l_Cur = mContentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.NUMBER +" = ?",
new String[]{lNumber }, null);
while (l_Cur.moveToNext())
{
cid = l_Cur.getString(l_Cur.getColumnIndex(
ContactsContract.CommonDataKinds.Phone.CONTACT_ID));
}
System.out.println("The contact ID for person with phone number "+ lNumber + " is " + cid);
if(!(cid.equals("Unknown")))
{
Cursor cursor_contacts = mContentResolver.query(ContactsContract.Contacts.CONTENT_URI,
null,
ContactsContract.Contacts._ID + " = ?",
new String[]{cid },
null);
while(cursor_contacts.moveToNext())
{
displayname = cursor_contacts.getString(cursor_contacts.getColumnIndex(
ContactsContract.Contacts.DISPLAY_NAME));
photoid = cursor_contacts.getString(cursor_contacts.getColumnIndex(
ContactsContract.Contacts.PHOTO_ID));
}
System.out.println("The display name & photo id for person with phone number "
+ lNumber + " is " + displayname + " & " + photoid);
Uri contactPhotoUri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, Integer.parseInt(cid));
// Uri photoUri = Uri.withAppendedPath(contactPhotoUri, Contacts.Photo.CONTENT_DIRECTORY);
// contactPhotoUri --> content://com.android.contacts/contacts/1557
InputStream photoDataStream = Contacts.openContactPhotoInputStream(mContentResolver,contactPhotoUri); // <-- always null
if(photoDataStream == null)
{
System.out.println("No photo available ");
}
Bitmap bt = BitmapFactory.decodeStream(photoDataStream);
setmPhoto(bt);
}
return displayname;
}
Thanks in advance.
