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))));
}

I want to load cover audio art in android for show list of audio from device. For this purpose i used this following Link:

way3
Like following picture:
And my code for Load audio files:
private void loadAudio() {
ContentResolver contentResolver = getContentResolver();
Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
String selection = MediaStore.Audio.Media.IS_MUSIC + "!= 0";
String sortOrder = MediaStore.Audio.Media.TITLE + " ASC";
Cursor cursor = contentResolver.query(uri, null, selection, null, sortOrder);
if (cursor != null && cursor.getCount() > 0) {
audioList.clear();
while (cursor.moveToNext()) {
String data = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DATA));
String title = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.TITLE));
String album = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.ALBUM));
String artist = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.ARTIST));
int albumId = cursor.getInt(cursor.getColumnIndex(MediaStore.Audio.Media.ALBUM_ID));
Cursor cursor1 = contentResolver.query(MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI,
new String[]{MediaStore.Audio.Albums._ID, MediaStore.Audio.Albums.ALBUM_ART},
MediaStore.Audio.Albums._ID + "=" + albumId, null, null);
Bitmap bitmap = null;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.Q) {
try {
bitmap = contentResolver.loadThumbnail(MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI, new Size(30, 30), null);
} catch (IOException e) {
e.printStackTrace();
}
}
String albumArt = "";
if (cursor1 != null && cursor1.getCount() > 0)
while (cursor1.moveToNext()) {
albumArt = cursor.getString(cursor1.getColumnIndex(MediaStore.Audio.Albums.ALBUM_ART));
}
// Save to audioList
audioList.add(new Audio(data, title, album, artist, albumArt, bitmap));
}
}
cursor.close();
setAdapter();
}
And in MyAdapter about recyclerview:
#Override
public void onBindViewHolder(#NonNull MainHolder holder, int position) {
Audio audio = arrayList.get(position);
holder.txtTitle.setText("Title: " + audio.getTitle());
holder.txtAlbum.setText("Album: " + audio.getAlbum());
holder.txtArtist.setText("Artist: " + audio.getArtist());
File imgFile = new File(audio.getAlbumArt());
Picasso.get().load(imgFile.getAbsolutePath()).into(holder.img);
if (imgFile.exists()) {
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
holder.img.setImageBitmap(myBitmap);
}
}
Help me please.
Solved:
Load audio file:
private void loadAudio() {
ContentResolver contentResolver = getContentResolver();
Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
String selection = MediaStore.Audio.Media.IS_MUSIC + "!= 0";
String sortOrder = MediaStore.Audio.Media.ARTIST + " DESC";
Cursor cursor = contentResolver.query(uri, null, selection, null, sortOrder);
if (cursor != null && cursor.getCount() > 0) {
audioList.clear();
while (cursor.moveToNext()) {
Audio audio = new Audio();
String data = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DATA));
String title = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.TITLE));
String album = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.ALBUM));
String artist = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.ARTIST));
int albumId = cursor.getInt(cursor.getColumnIndex(MediaStore.Audio.Media.ALBUM_ID));
Bitmap thumbnail = null;
String albumArt = null;
Uri imageUri_t;
Cursor cursor1 = contentResolver.query(MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI,
new String[]{MediaStore.Audio.Albums._ID, MediaStore.Audio.Albums.ALBUM_ART},
MediaStore.Audio.Albums._ID + "=" + albumId, null, null);
while (cursor1.moveToNext()) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
Size thumbSize = new Size(100, 100);
try {
int thumbColumn = cursor1.getColumnIndexOrThrow(MediaStore.Audio.Albums._ID);
int _thumpId = cursor1.getInt(thumbColumn);
imageUri_t = ContentUris.withAppendedId(MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI, _thumpId);
thumbnail = getContentResolver().loadThumbnail(imageUri_t, thumbSize, null);
} catch (IOException e) {
e.printStackTrace();
}
} else {
albumArt = cursor1.getString(cursor1.getColumnIndex(MediaStore.Audio.Albums.ALBUM_ART));
}
}
audio.setData(data);
audio.setTitle(title);
audio.setAlbum(album);
audio.setArtist(artist);
audio.setAlbumId(albumId);
audio.setAlbumArt(albumArt);
audio.setThumbnail(thumbnail);
audioList.add(audio);
}
}
cursor.close();
setAdapter();
}
And a part of MyAdapter:
#Override
public void onBindViewHolder(#NonNull MainHolder holder, int position) {
Audio audio = arrayList.get(position);
holder.txtTitle.setText("Title: " + audio.getTitle());
holder.txtAlbum.setText("Album: " + audio.getAlbum());
holder.txtArtist.setText("Artist: " + audio.getArtist());
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
if (audio.getThumbnail() != null)
holder.img.setImageBitmap(audio.getThumbnail());
} else {
if (audio.getAlbumArt() != null) {
File imgFile = new File(audio.getAlbumArt());
if (imgFile.exists()) {
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
holder.img.setImageBitmap(myBitmap);
}
}
}
}
First query on MediaStore.Audio.Media.ARTIST about fetch audio info from MediaStore.
There is a difference About fetch thumbnail of Audio file in android 10 (Q) and below.
So query for lower than Android 10 is like follow:
String albumArt = cursor1.getString(cursor1.getColumnIndex(MediaStore.Audio.Albums.ALBUM_ART));
You can get album art from ALBUM_ART column in MediaStore.Audio.Albums.
Then for Android 10 like follow this:
Query on MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI where albumId equals _ID column from MediaStore.Audio.Albums.
And load thumbnail from Content Resolver by image uri...
I hope it is useful ;)
My code is working fine on any device .. but not working on android pie
I am trying to get the real path and the file name from the onActivityResult in a Fragment
and I am using the FileNameUtils from the apachi library
and using this library
https://gist.github.com/tatocaster/32aad15f6e0c50311626
but its giving me null
and this is my code
private void pickFile() {
Intent intent = new Intent();
intent.setType("*/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select File"), PICKFILE_REQUEST_CODE);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PICKFILE_REQUEST_CODE) {
filePath = RealPathUtil.getRealPath(getContext(), data.getData());
fileName = FilenameUtils.getName(filePath);
Log.i("FileNameIs",filePath + "Hello " + fileName );
// if (fileName !=null)
// {
// mFileName
// .setText(fileName.isEmpty() ? getString(R.string.failed_please_try_again) : fileName);
//
// deleteOldPath();
//
// }
}
}
updated .. Fixed it by the next ..
first
to get the file name
i used this function
public void dumpImageMetaData(Uri uri) {
String TAG = "TagIs";
// The query, since it only applies to a single document, will only return
// one row. There's no need to filter, sort, or select fields, since we want
// all fields for one document.
Cursor cursor = getActivity().getContentResolver()
.query(uri, null, null, null, null, null);
try {
// moveToFirst() returns false if the cursor has 0 rows. Very handy for
// "if there's anything to look at, look at it" conditionals.
if (cursor != null && cursor.moveToFirst()) {
// Note it's called "Display Name". This is
// provider-specific, and might not necessarily be the file name.
String displayName = cursor.getString(
cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME));
fileName = displayName ==null ? "Failed" : displayName;
deleteOldPath();
}
} finally {
cursor.close();
}
}
then i used this methods from this post
Get Real Path For Uri Android
to get the file Path
public static String getPath(final Context context, final Uri uri) {
final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
Log.i("URI",uri+"");
String result = uri+"";
// DocumentProvider
// if (isKitKat && DocumentsContract.isDocumentUri(context, uri)) {
if (isKitKat && (result.contains("media.documents"))) {
String[] ary = result.split("/");
int length = ary.length;
String imgary = ary[length-1];
final String[] dat = imgary.split("%3A");
final String docId = dat[1];
final String type = dat[0];
Uri contentUri = null;
if ("image".equals(type)) {
contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
} else if ("video".equals(type)) {
} else if ("audio".equals(type)) {
}
final String selection = "_id=?";
final String[] selectionArgs = new String[] {
dat[1]
};
return getDataColumn(context, contentUri, selection, selectionArgs);
} else if ("content".equalsIgnoreCase(uri.getScheme())) {
return getDataColumn(context, uri, null, null);
}
// File
else if ("file".equalsIgnoreCase(uri.getScheme())) {
return uri.getPath();
}
return null;
}
public static String getDataColumn(Context context, Uri uri, String selection, String[] selectionArgs) {
Cursor cursor = null;
final String column = "_data";
final String[] projection = {
column
};
try {
cursor = context.getContentResolver().query(uri, projection, selection, selectionArgs, null);
if (cursor != null && cursor.moveToFirst()) {
final int column_index = cursor.getColumnIndexOrThrow(column);
return cursor.getString(column_index);
}
} finally {
if (cursor != null)
cursor.close();
}
return null;
}
look at this . android reference
I'm trying to get a Bitmap from a video which I get from the device's gallery or the camera, but when I call this, I'm getting a null Bitmap:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Uri uri = data.getData();
if (requestCode == REQUEST_VIDEO_CAPTURE && resultCode == RESULT_OK) {
Uri videoUri = data.getData(); // -> content://com.android.providers.media.documents/document/video%3A76
// This returns null
Bitmap thumbnailVideo = ThumbnailUtils.createVideoThumbnail(videoUri.toString(), MediaStore.Video.Thumbnails.MICRO_KIND);
media1.setImageBitmap(thumbnailVideo);
}
I also tried using this, but it stills returns a null value:
String path = uri.getPath(); // -> /document/video:76
Bitmap thumbnailVideo = ThumbnailUtils.createVideoThumbnail(path , MediaStore.Video.Thumbnails.MICRO_KIND);
And the last thing I tried is this code, but as before, it doesn't work:
String[] filePathColumn = {MediaStore.Video.Media.DATA};
Cursor cursor = this.getContentResolver().query(uri, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
Bitmap thumbnailVideo = ThumbnailUtils.createVideoThumbnail(picturePath, MediaStore.Video.Thumbnails.MICRO_KIND);
What am I doing wrong? I tried different solutions from Stackoverflow but none of them seem to work for me.
I found a way to make this work.
try {
Bitmap thumbnailVideo;
if (Build.VERSION.SDK_INT < 19) {
thumbnailVideo = ThumbnailUtils.createVideoThumbnail(getRealPathFromURIForVideoAPI18(videoUri), MediaStore.Video.Thumbnails.MICRO_KIND);
}
else {
thumbnailVideo = ThumbnailUtils.createVideoThumbnail(getRealPathFromURIForVideoAPI19(videoUri), MediaStore.Video.Thumbnails.MICRO_KIND);
}
setThumbnail(thumbnailVideo);
} catch (Exception ex) {
ex.printStackTrace();
}

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);
}
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!

It is possible to query both internal and external MediaStore database also with MergeCursor:

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));
}
