how to get music album art cover programmatically

I want to get music album covers to display them in imageview of gridview.
and this is my code
void loadAudioData() {
ContentResolver contentResolver = Objects.requireNonNull(getActivity()).getContentResolver();
final Uri uri = MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI;
final String albumId = MediaStore.Audio.Albums._ID;
final String albumName = MediaStore.Audio.Albums.ALBUM;
final String artist = MediaStore.Audio.Albums.ARTIST;
final String albumArt = MediaStore.Audio.AlbumColumns.ALBUM_ART;
final String album_id = MediaStore.Audio.AlbumColumns.ALBUM_ID;
final Uri sArtworkUri = Uri.parse("content://media/external/audio/albumart");
String[] projection = {albumId, albumName, artist, albumArt, album_id};
Cursor cursor = contentResolver.query(uri, projection, null, null, null);
Bitmap bitmap = null;
if (cursor != null && cursor.moveToFirst())
while (cursor.moveToNext()) {
long album_idx = cursor.getLong(cursor.getColumnIndexOrThrow(album_id));
Uri albumArtUri = ContentUris.withAppendedId(sArtworkUri, album_idx);
try {
bitmap = MediaStore.Images.Media.getBitmap(getContext().getContentResolver(), albumArtUri);
} catch (IOException e) {
Log.e("bitmap = null", "bitmap = null");
}
if (bitmap == null)
songsList.add(new Songs(R.drawable.album_cover, cursor.getString(cursor.getColumnIndex(albumName)),
cursor.getString(cursor.getColumnIndex(artist))));
else
songsList.add(new Songs(bitmap, cursor.getString(cursor.getColumnIndex(albumName)),
cursor.getString(cursor.getColumnIndex(artist))));
}
cursor.close();
}
the problem is that bitmap is always null and else statement always executes although there is cover images for albums and they are shown in other installed apps.
i tried too many solutions but non of them helped to the end

Try getting Bitmap using FileDescriptor. See the updated code:
while (cursor.moveToNext()) {
long album_idx = cursor.getLong(cursor.getColumnIndexOrThrow(album_id));
Uri albumArtUri = ContentUris.withAppendedId(sArtworkUri, album_idx);
try {
ParcelFileDescriptor pfd = getContext().getContentResolver().openFileDescriptor(uri, "r");
if (pfd != null) {
FileDescriptor fd = pfd.fileDescriptor;
bitmap = BitmapFactory.decodeFileDescriptor(fd, null,options);
pfd.close();
fd = null;
}
}catch (IOException e) {
Log.e("bitmap = null", "bitmap = null");
}
if (bitmap == null)
songsList.add(new Songs(R.drawable.album_cover, cursor.getString(cursor.getColumnIndex(albumName)),
cursor.getString(cursor.getColumnIndex(artist))));
else
songsList.add(new Songs(bitmap, cursor.getString(cursor.getColumnIndex(albumName)),
cursor.getString(cursor.getColumnIndex(artist))));
}

how to get photo_uri from photo_id

I go through the addressbook and try to get all contacts' photos which are not null.
I'm using android API8, so i cannot query for image_uri.
given photo_id (API 5), how can i get the photo bitmap?
here is my query:
public final static String[] PROJECTION2 = new String[] {
ContactsContract.CommonDataKinds.Phone.RAW_CONTACT_ID,
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.PHOTO_ID
};
public static void fillAddressBookData() {
String sHash = null;
String where = ContactsContract.Contacts.IN_VISIBLE_GROUP + "= ? ";
String[] selectionArgs = new String[] {"1"};
Cursor cursor =
AppService
.getAppContext()
.getContentResolver()
.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, PROJECTION2, where,
selectionArgs, null);
...

try this:
private void GetImageByPhoneNumber(String number)
{
Uri uri1 = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI,
Uri.encode(number));
Cursor test = getContentResolver().query(uri1,
new String[] { "photo_uri" }, null, null,
null);
if (test.getCount() > 0) {
test.moveToFirst();
Uri photoUri = Uri.parse(test.getString(test
.getColumnIndexOrThrow("photo_uri"))));
Bitmap image = getPhoto(context , photoUri);
}
test.close();
}
and getPhoto:
public static Bitmap getPhoto(Context context , Uri uri){
Bitmap bm = null;
try {
bm = BitmapFactory.decodeStream(context.getContentResolver()
.openInputStream(uri));
} catch (FileNotFoundException e) {
e.printStackTrace();
}
if (bm == null) {
bm = BitmapFactory.decodeResource(context.getResources(),
R.drawable.default_user_avatar);
}
return bm;
}

Try the next code snippet, it should do the trick
public Uri getPhotoUri(long contactId) {
ContentResolver contentResolver = getContentResolver();
try {
Cursor cursor = contentResolver
.query(ContactsContract.Data.CONTENT_URI,
null,
ContactsContract.Data.CONTACT_ID
+ "="
+ contactId
+ " AND "
+ ContactsContract.Data.MIMETYPE
+ "='"
+ ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE
+ "'", null, null);
if (cursor != null) {
if (!cursor.moveToFirst()) {
return null; // no photo
}
} else {
return null; // error in cursor process
}
} catch (Exception e) {
e.printStackTrace();
return null;
}
Uri person = ContentUris.withAppendedId(
ContactsContract.Contacts.CONTENT_URI, contactId);
return Uri.withAppendedPath(person,
ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);
}

Android get Media.Images Uri from ID

I am new to Android and Java and this week I've been doing a self-taught crash course. So far what I've learned has not been too complicated as I've already built a number of years of coding experience. So, background history out of the way, onto my question.
The below code is two functions I wrote to take an image ID from a database and parse the correct Uri which I can then use to upload the photo to a website. So could you kind folks look over my code and let me know if I'm doing a terrible job or if I am heading in the right direction or even if there is a better/native way to do what I need.
Also, note: the below code does work. I just don't know if it is the right way to do it.
Thanks!
// Usage Map idPath = ImageIdPathFetcher.getRealIdPathFromID(getApplicationContext(), Integer.valueOf(image_id));
public static Map getRealIdPathFromID(Context context, Integer id) {
Map<String,String> idPath = new HashMap<String, String>();
Uri external_images_uri = MediaStore.Images.Media.getContentUri("external");
Uri internal_images_uri = MediaStore.Images.Media.getContentUri("internal");
// initialize uri
Uri uri = external_images_uri;
String ext_img_uri = external_images_uri.toString()+"/"+id;
String int_img_uri = internal_images_uri.toString()+"/"+id;
if(check_uri(context, ext_img_uri))
{
uri = Uri.parse(ext_img_uri);
}else if(check_uri(context, int_img_uri))
{
uri = Uri.parse(int_img_uri);
}else {
idPath.put("id", "");
idPath.put("path", "");
return idPath;
}
String[] proj = { Media.DATA, Media._ID };
Cursor cursor = context.getContentResolver().query(uri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(Media.DATA);
cursor.moveToFirst();
String filepath = cursor.getString(column_index);
idPath.put("id", id.toString());
idPath.put("path", filepath);
return idPath;
}
public static boolean check_uri(Context context, String uri)
{
try{
ContentResolver cr = context.getContentResolver();
String[] projection = {MediaStore.MediaColumns.DATA};
Cursor cur = cr.query(Uri.parse(uri), projection, null, null, null);
if(cur != null)
{
cur.moveToFirst();
String filePath = cur.getString(0);
if(! new File(filePath).exists()){
return false;
}
} else {
return false;
}
} catch (Exception e)
{
return false;
}
return true;
}

This is what I use
public static Uri getImageContentUri(Context context, File imageFile) {
String filePath = imageFile.getAbsolutePath();
Cursor cursor = context.getContentResolver().query(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
new String[]{MediaStore.Images.Media._ID},
MediaStore.Images.Media.DATA + "=? ",
new String[]{filePath}, null);
if (cursor != null) {
try {
if (cursor.moveToFirst()) {
int id = cursor.getInt(cursor.getColumnIndex(MediaStore.MediaColumns._ID));
return Uri.withAppendedPath(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, String.valueOf(id));
}
} finally {
cursor.close();
}
}
cursor = context.getContentResolver().query(
MediaStore.Images.Media.INTERNAL_CONTENT_URI,
new String[]{MediaStore.Images.Media._ID},
MediaStore.Images.Media.DATA + "=? ",
new String[]{filePath}, null);
if (cursor != null) {
try {
if (cursor.moveToFirst()) {
int id = cursor.getInt(cursor.getColumnIndex(MediaStore.MediaColumns._ID));
return Uri.withAppendedPath(MediaStore.Images.Media.INTERNAL_CONTENT_URI, String.valueOf(id));
}
} finally {
cursor.close();
}
}
return null;
}

It is possible to query both internal and external MediaStore database also with MergeCursor:
String myIdImgStr = "123"; // the unique ID of the image in the MediaStore
ContentResolver contentResolver = this.getContext().getContentResolver();
String [] proj = { MediaStore.Images.Media.DATA, MediaStore.Images.Media._ID };
MergeCursor cursor = new MergeCursor(new Cursor[] {
MediaStore.Images.Media.query(contentResolver,
Uri.parse(MediaStore.Images.Media.INTERNAL_CONTENT_URI + "/" + myIdImgStr),
proj),
MediaStore.Images.Media.query(contentResolver,
Uri.parse(MediaStore.Images.Media.EXTERNAL_CONTENT_URI + "/" + myIdImgStr),
proj)
});
if(cursor.getCount() == 1) {
cursor.moveToFirst();
String filepath = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
}

How to get the Path from an Uri id from a File?

I've tried to make a gallery out of the Videos created with my app.
When I click on one of the Thumbnail pictures I want to save the selected Video in my preferences.
To get the Thumbnails I wrote following code:
public void addVidsToArray()
{
String[] projection = { MediaStore.Video.Media._ID };
String selection = MEDIA_DATA + " like ? ";
String [] selectionArgs = new String[] {"%Bla%"};
int columIndex;
int id;
Cursor videoCursor = managedQuery(MediaStore.Video.Media.EXTERNAL_CONTENT_URI,
projection,
selection,
selectionArgs,
null);
videoCursor.moveToFirst();
if(videoCursor.getCount() >= 1)
{
while (videoCursor.moveToNext()) {
columIndex = videoCursor.getColumnIndexOrThrow(MediaStore.Video.Media._ID) ;
id = videoCursor.getInt(columIndex);
bitmaps.add(getThumbnail(id));
}
}
}
public Bitmap getThumbnail(int id)
{
ContentResolver crThumb = getContentResolver();
BitmapFactory.Options options=new BitmapFactory.Options();
options.inSampleSize = 1;
Bitmap curThumb = MediaStore.Video.Thumbnails.getThumbnail(crThumb, id, MediaStore.Video.Thumbnails.MICRO_KIND, options);
curThumb = Bitmap.createScaledBitmap(curThumb, 300, 300, false);
return curThumb;
}
I get the Tumbnail Pics due to the Uri id.
Now my Problem is how to bring that back to a normal path in a new File to saved it.
Following code is the the onClickListener which should save the video to the preferences.
But if I add the Uri to the new File, the file doesen't exsist.
I don't get it.
ga.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View v, int position, long id)
{
String[] projection = { MediaStore.Video.Media._ID };
String selection = MEDIA_DATA + " like ? ";
String [] selectionArgs = new String[] {"%Bla%"};
int columIndex;
int id1;
Cursor videoCursor = managedQuery(MediaStore.Video.Media.EXTERNAL_CONTENT_URI,
projection,
selection,
selectionArgs,
null);
videoCursor.moveToFirst();
if(videoCursor.getCount() >= 1)
{
while (videoCursor.moveToNext()) {
columIndex = videoCursor.getColumnIndexOrThrow(MediaStore.Video.Media._ID) ;
id1 = videoCursor.getInt(columIndex);
daten.add(id1+"");
}
}
Log.v("vid id", ""+daten.get(position));
int idData = Integer.parseInt(daten.get(position));
saveVideo(idData);
}
});
}
public void saveVideo(int idData)
{
String uriString = "content://media/external/video/media/" + idData;
Uri uri = Uri.parse(uriString);
File mVideoFile = new File(uriString);
Log.v("testpfad", ""+ mVideoFile.getAbsolutePath() + " " + mVideoFile.getParentFile().getAbsolutePath() + " " + mVideoFile.exists());
mVideoFileLen = getDurationFromURI(uri);
//setPreferences(mVideoFile.getAbsolutePath(), PICKED_VIDEO);
//setPreferences(mVideoFileLen, VIDEO_LEN);
//startActivity(new Intent(this, Finished.class));
}
In the end I need to create a File with the help of the Id from the Uri.

Get contact name given a phone number in Android

I am trying to retrieve contact names given the contact phone number. I made a function that should work in all API versions, by I can't make it work in 1.6 and I can't see the problem, maybe someone can spot it?
Note that, I've replaced the API constants for strings so I don't have deprecated warning problems.
public String getContactName(final String phoneNumber)
{
Uri uri;
String[] projection;
if (Build.VERSION.SDK_INT >= 5)
{
uri = Uri.parse("content://com.android.contacts/phone_lookup");
projection = new String[] { "display_name" };
}
else
{
uri = Uri.parse("content://contacts/phones/filter");
projection = new String[] { "name" };
}
uri = Uri.withAppendedPath(uri, Uri.encode(phoneNumber));
Cursor cursor = this.getContentResolver().query(uri, projection, null, null, null);
String contactName = "";
if (cursor.moveToFirst())
{
contactName = cursor.getString(0);
}
cursor.close();
cursor = null;
return contactName;
}

This seems to work fine in the latest versions:
private String getContactName(Context context, String number) {
String name = null;
// define the columns I want the query to return
String[] projection = new String[] {
ContactsContract.PhoneLookup.DISPLAY_NAME,
ContactsContract.PhoneLookup._ID};
// encode the phone number and build the filter URI
Uri contactUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
// query time
Cursor cursor = context.getContentResolver().query(contactUri, projection, null, null, null);
if(cursor != null) {
if (cursor.moveToFirst()) {
name = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));
Log.v(TAG, "Started uploadcontactphoto: Contact Found # " + number);
Log.v(TAG, "Started uploadcontactphoto: Contact name = " + name);
} else {
Log.v(TAG, "Contact Not Found # " + number);
}
cursor.close();
}
return name;
}

Use reflections instead of comparing sdk version.
public String getContactName(final String phoneNumber)
{
Uri uri;
String[] projection;
mBaseUri = Contacts.Phones.CONTENT_FILTER_URL;
projection = new String[] { android.provider.Contacts.People.NAME };

mBaseUri = (Uri) c.getField("CONTENT_FILTER_URI").get(mBaseUri);
projection = new String[] { "display_name" };
}
catch (Exception e) {
}
uri = Uri.withAppendedPath(mBaseUri, Uri.encode(phoneNumber));
Cursor cursor = this.getContentResolver().query(uri, projection, null, null, null);
String contactName = "";
if (cursor.moveToFirst())
{
contactName = cursor.getString(0);
}
cursor.close();
cursor = null;
return contactName;
}

if (cursor == null)
{
return null;
}
String contactName = null;
if(cursor.moveToFirst())
{
contactName = cursor.getString(cursor.getColumnIndex(PhoneLookup.DISPLAY_NAME));
}
if(cursor != null && !cursor.isClosed()) {
cursor.close();
}
return contactName;
}

private String getContactNameFromNumber(String number) {
Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
Cursor cursor = context.getContentResolver().query(uri, new String[]{PhoneLookup.DISPLAY_NAME},null,null,null);
if (cursor.moveToFirst())
{
