Ok so I've been working on this project for a few days now and most of my time has been working out how to list all the music on a device in a LIST VIEW or something else, I have searched for a few days now and this is killing me. I did get so close at one point with all the music in one folder showing, though since most people will have sub folders for things like artiest and albums I need a way to search sub folders for MP3s or music files.
Here is what I have so far for Music collection:
package com.androidhive.musicplayer;
import java.io.File;
import java.io.FilenameFilter;
import java.util.ArrayList;
import java.util.HashMap;
import android.provider.MediaStore;
public class SongsManager {
// SDCard Path
final String MEDIA_PATH = new String(MediaStore.Audio.Media.getContentUri("external").toString());
private ArrayList<HashMap<String, String>> songsList = new ArrayList<HashMap<String, String>>();
// Constructor
public SongsManager(){
}
/**
* Function to read all mp3 files from sdcard
* and store the details in ArrayList
* */
public ArrayList<HashMap<String, String>> getPlayList(){
File home = new File(MEDIA_PATH);
if (home.listFiles(new FileExtensionFilter()).length > 0) {
for (File file : home.listFiles(new FileExtensionFilter())) {
HashMap<String, String> song = new HashMap<String, String>();
song.put("songTitle", file.getName().substring(0, (file.getName().length() - 4)));
song.put("songPath", file.getPath());
// Adding each song to SongList
songsList.add(song);
}
}
// return songs list array
return songsList;
}
/**
* Class to filter files which are having .mp3 extension
* */
class FileExtensionFilter implements FilenameFilter {
public boolean accept(File dir, String name) {
return (name.endsWith(".mp3") || name.endsWith(".MP3"));
}
}
}
Thanks to anyone who can help. :)
Although, the post is old, for other people like me to get the idea of creating a list of music with their file path, I added the solution here. MediaStore.Audio.Media.DATA column actually contains media file path. You can get necessary information by using the following snippet:
ContentResolver cr = getActivity().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 cur = cr.query(uri, null, selection, null, sortOrder);
int count = 0;
if(cur != null)
{
count = cur.getCount();
if(count > 0)
{
while(cur.moveToNext())
{
String data = cur.getString(cur.getColumnIndex(MediaStore.Audio.Media.DATA));
// Add code to get more column here
// Save to your list here
}
}
cur.close();
}
You can list all the music files using this code
//Some audio may be explicitly marked as not being music
String selection = MediaStore.Audio.Media.IS_MUSIC + " != 0";
String[] projection = {
MediaStore.Audio.Media._ID,
MediaStore.Audio.Media.ARTIST,
MediaStore.Audio.Media.TITLE,
MediaStore.Audio.Media.DATA,
MediaStore.Audio.Media.DISPLAY_NAME,
MediaStore.Audio.Media.DURATION
};
cursor = this.managedQuery(
MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,
projection,
selection,
null,
null);
private List<String> songs = new ArrayList<String>();
while(cursor.moveToNext()) {
songs.add(cursor.getString(0) + "||"
+ cursor.getString(1) + "||"
+ cursor.getString(2) + "||"
+ cursor.getString(3) + "||"
+ cursor.getString(4) + "||"
+ cursor.getString(5));
}
I have not tried this code, but it seems correct. You'll be on the right track with that.
I'm working on same project right now and already solved the problem.
You will need a custom class to store your songs data:
package YOUR_PACKAGE;
public class Songs
{
private long mSongID;
private String mSongTitle;
public Songs(long id, String title){
mSongID = id;
mSongTitle = title;
}
public long getSongID(){
return mSongID;
}
public String getSongTitle(){
return mSongTitle;
}
}
Then you have to define ArrayList in activity with List View which you will populate with data:
private ArrayList<Songs> arrayList;
and in onCreate:
arrayList = new ArrayList<Songs>();
Then you have to retrieve data from your device:
public void YOUR_METHOD_NAME(){
ContentResolver contentResolver = getContentResolver();
Uri songUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
Cursor songCursor = contentResolver.query(songUri, null, null, null, null);
if(songCursor != null && songCursor.moveToFirst())
{
int songId = songCursor.getColumnIndex(MediaStore.Audio.Media._ID);
int songTitle = songCursor.getColumnIndex(MediaStore.Audio.Media.TITLE);
do {
long currentId = songCursor.getLong(songId);
String currentTitle = songCursor.getString(songTitle);
arrayList.add(new Songs(currentId, currentTitle, currentArtist));
} while(songCursor.moveToNext());
}
}
Then call this method from onCreate:
YOUR_METHOD_NAME();
And finally you have to create custom adapter class, define this adapter in onCreate (in activity with ListView) and set this adapter on your ListView object.
I see that it was asked 3 years ago and the problem I think already solved, but maybe it will be usefull for someone. Thanks.
Here is a simple function who gives you all audio files in File Object.
public static List<File> getAllAudios(Context c) {
List<File> files = new ArrayList<>();
String[] projection = { MediaStore.Audio.AudioColumns.DATA ,MediaStore.Audio.Media.DISPLAY_NAME};
Cursor cursor = c.getContentResolver().query(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, projection, null, null, null);
try {
cursor.moveToFirst();
do{
files.add((new File(cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DATA)))));
}while(cursor.moveToNext());
cursor.close();
} catch (Exception e) {
e.printStackTrace();
}
return files;
}

I want to know how to fetch all PDF files from internal storage. Files can be in any directory, like some in DCIM folders or some in Downloads folder, and so on and so forth.
Note: I am using Android Studio (language: Java).
i have search almost all the ans but it was not working in Android 11. so i have a short solution for picking up all file for example image, video, pdf, doc, audio etc. there was a github library which was recently created
Click [here] https://github.com/HBiSoft/PickiT
and if you want to do all this without dependency
Code Below
do it in orderwise

You can use MediaStore to fetch all PDF Files ,this is an example how to get all your PDF files :
protected ArrayList<String> getPdfList() {
ArrayList<String> pdfList = new ArrayList<>();
Uri collection;
final String[] projection = new String[]{
MediaStore.Files.FileColumns.DISPLAY_NAME,
MediaStore.Files.FileColumns.DATE_ADDED,
MediaStore.Files.FileColumns.DATA,
MediaStore.Files.FileColumns.MIME_TYPE,
};
final String sortOrder = MediaStore.Files.FileColumns.DATE_ADDED + " DESC";
final String selection = MediaStore.Files.FileColumns.MIME_TYPE + " = ?";
final String mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension("pdf");
final String[] selectionArgs = new String[]{mimeType};
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
collection = MediaStore.Files.getContentUri(MediaStore.VOLUME_EXTERNAL);
}else{
collection = MediaStore.Files.getContentUri("external");
}
try (Cursor cursor = getContentResolver().query(collection, projection, selection, selectionArgs, sortOrder)) {
assert cursor != null;
if (cursor.moveToFirst()) {
int columnData = cursor.getColumnIndex(MediaStore.Files.FileColumns.DATA);
int columnName = cursor.getColumnIndex(MediaStore.Files.FileColumns.DISPLAY_NAME);
do {
pdfList.add((cursor.getString(columnData)));
Log.d(TAG, "getPdf: " + cursor.getString(columnData));
//you can get your pdf files
} while (cursor.moveToNext());
}
}
return pdfList;
}
This is improvised answer of #Shay Kin.
As we know in latest android versions we have many restrictions to access files in external storage.
MediaStore api and Storage Access Framework apis provides access to shared files. This is explained clearly in this video.
Coming to the answer, in Shay Kin's answer we can able to fetch all pdf files which are there in the shared files but ignores downloads.
Permissions required
READ_EXTERNAL_STORAGE
if api is Q plus you also need MANAGE_EXTERNAL_STORAGE
please find the below code to fetch all pdf files.
protected List<String> getPdfList() {
List<String> pdfList = new ArrayList<>();
final String[] projection = new String[]{
MediaStore.Files.FileColumns.DISPLAY_NAME,
MediaStore.Files.FileColumns.DATE_ADDED,
MediaStore.Files.FileColumns.DATA,
MediaStore.Files.FileColumns.MIME_TYPE,
};
final String sortOrder = MediaStore.Files.FileColumns.DATE_ADDED + " DESC";
final String selection = MediaStore.Files.FileColumns.MIME_TYPE + " = ?";
final String mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension("pdf");
final String[] selectionArgs = new String[]{mimeType};
Uri collection = MediaStore.Files.getContentUri("external");
pdfList.addAll(getPdfList(collection, projection, selection, selectionArgs, sortOrder));
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
collection = MediaStore.Downloads.getContentUri("external");
pdfList.addAll(getPdfList(collection,projection, selection, selectionArgs, sortOrder));
}
return pdfList;
}
private List<String> getPdfList(Uri collection, String[] projection, String selection, String[] selectionArgs, String sortOrder) {
List<String> pdfList = new ArrayList<>();
try (Cursor cursor = getContentResolver().query(collection, projection, selection, selectionArgs, sortOrder)) {
assert cursor != null;
if (cursor.moveToFirst()) {
int columnData = cursor.getColumnIndex(MediaStore.Files.FileColumns.DATA);
do {
pdfList.add((cursor.getString(columnData)));
Log.d(TAG, "getPdf: " + cursor.getString(columnData));
//you can get your pdf files
} while (cursor.moveToNext());
}
}
return pdfList;
}
Hope this works.

I want to create an android gallery app .
How to scan and get paths of folders that includes photos or videos .
I used this code and worked . but when i compare it with Quickpic Gallery in play store , i see the count of folders in my app is less than Quickpic folders
Do you see any problem in this code ?
Uri uri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
Cursor cursor = ba.context.getContentResolver().query(uri, null, null,
null, MediaStore.Images.ImageColumns.BUCKET_DISPLAY_NAME);
if (cursor != null) {
cursor.moveToFirst();
int data = cursor
.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
int displayName = cursor
.getColumnIndex(MediaStore.Images.ImageColumns.DISPLAY_NAME);
imageFolders = new HashMap<>();
do {
String imageAddress = cursor.getString(data);
String imageName = cursor.getString(displayName);
String folderAddress = imageAddress.substring(0,
imageAddress.lastIndexOf(imageName) - 1);
if (!imageFolders.containsKey(folderAddress)) {
imageFolders.put(folderAddress, imageAddress);
}
} while (cursor.moveToNext());
for (String str : imageFolders.keySet()) {

null,
null,
0,
"result",
true,
new Object[] { String.format("%s", str),

i can see you are trying to get the folder names of all folders containing video files the answer given by #prakash ubhadiya is good an works but for the problem that if the are many of such folders with same name the function will keep only one and ignore the rest, below i have modified his fuction to return not only the folder names but also the folder absolute path in case you will want to use this to get all the video files in that specific folder, i have created a class called floderFacer the holds the folder name and the folder adsolute path, done this way no folders with same names will be ignored below is the class
public class folderFacer {
private String path;
private String folderName;
public folderFacer(){
}
public folderFacer(String path, String folderName) {
this.path = path;
this.folderName = folderName;
}
public String getPath() {
return path;
}
public void setPath(String path) {
this.path = path;
}
public String getFolderName() {
return folderName;
}
public void setFolderName(String folderName) {
this.folderName = folderName;
}
}
now below is the modified fuction that will return the folder names and paths in a folderFacer object all in an ArrayList<folderFacer>
private ArrayList<folderFacer> getVideoPaths(){
ArrayList<folderFacer> videoFolders = new ArrayList<>();
ArrayList<String> videoPaths = new ArrayList<>();
Uri allVideosuri = android.provider.MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
String[] projection = { MediaStore.Video.VideoColumns.DATA ,MediaStore.Video.Media.DISPLAY_NAME,
MediaStore.Video.Media.BUCKET_DISPLAY_NAME,MediaStore.Video.Media.BUCKET_ID};
Cursor cursor = getContentResolver().query(allVideosuri, projection, null, null, null);
try {
cursor.moveToFirst();
do{
folderFacer folds = new folderFacer();
String name = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DISPLAY_NAME));
String folder = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Video.Media.BUCKET_DISPLAY_NAME));
String datapath = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DATA));
String folderpaths = datapath.replace(name,"");
if (!videoPaths.contains(folderpaths)) {
videoPaths.add(folderpaths);
folds.setPath(folderpaths);
folds.setFolderName(folder);
videoFolders.add(folds);
}
}while(cursor.moveToNext());
cursor.close();
} catch (Exception e) {
e.printStackTrace();
}
for(int i = 0;i < videoFolders.size();i++){
Log.d("video folders",videoFolders.get(i).getFolderName()+" and path = "+videoFolders.get(i).getPath());
}
return videoFolders;
}
hope this helps
I am working in Android application in which I am using ormlite. I am taking my phone book contacts and saving them in my local database, but the problem is that it is taking too much time like for almost 1500 contact it is taking almost 70 seconds.
I searched for the Bulk insert in ormlite, but I can't figure it out how to implement it in my following code.
public static void loadLocalPhoneBookSample(Context ctx) {
try{
ContentResolver contentRes = ctx.getContentResolver();
Cursor cur = null;
String selection = ContactsContract.Contacts.HAS_PHONE_NUMBER;
cur = contentRes.query(ContactsContract.Contacts.CONTENT_URI, PROJECTIONS, selection, null, Phone.DISPLAY_NAME + " ASC");
context = ctx;
if (cur.getCount() > 0) {
// create DB object
MUrgencyDBHelper db = new MUrgencyDBHelper(ctx);
RuntimeExceptionDao<ContactLocal, ?> contactDAO = db.getContactLocalIntDataDao();
UpdateBuilder<ContactLocal, ?> updateDAO = contactDAO.updateBuilder();
try {
updateDAO.updateColumnValue("isUseless", true);
updateDAO.update();
} catch (SQLException e) {
e.printStackTrace();
}finally {
// db.writeUnlock();
}
while (cur.moveToNext()) {
String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
/** read names **/
String displayName = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
/** Phone Numbers **/
Cursor pCur = contentRes.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?", new String[] { id }, null);
while (pCur.moveToNext()) {
String number = pCur
.getString(pCur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
String formatedNo = number.replaceAll("\\s+", "").replace("+", "00").replace("-", "").trim();
try {
QueryBuilder<ContactLocal, ?> query = contactDAO.queryBuilder();
query.where().eq("mFormatedNumber", number);
ContactLocal contact = query.queryForFirst();
boolean addContact = false, alreadyUpdated = true;
if (contact == null) {
addContact = true;
contact = new ContactLocal();
contact.setFirstName(displayName.trim());
contact.setLastName(displayName.trim());
contact.setContactNumber(formatedNo);
}
// check if this contact was already updated before
if (contact.getContactNumber() == null || contact.getContactNumber().length() == 0) {
contact.setContFirstLastNo(number, displayName, displayName, number);
alreadyUpdated = false;
}
contact.setUseless(false);
// if not updated already, Create/Update
if (addContact) {
contactDAO.create(contact);
} else
contactDAO.update(contact);
}
}
pCur.close();
}
}
}
the problem is that it is taking too much time like for almost 1500 contact it is taking almost 70 seconds
#CarloB has the right answer in terms of doing the mass creates inside the dao. callBatchTasks(...) method. Here's the docs on that subject:
http://ormlite.com/docs/batch
To make things a bit faster, you could also go through and record all of the mFormatedNumber in another List and then query for them using an IN query. Use a raw in query to get back the mFormatedNumber that are already in the database:
results = dao.queryRaw(
"SELECT mFormatedNumber from Contact WHERE mFormatedNumber IN ?",
mFormatedNumberList);
For using raw queries with ORMLite, see:
http://ormlite.com/docs/raw-queries
So then you would make one query to see which of the contacts need to be created and then do all of the inserts from within a batch transaction.
Otherwise you are doing ~3000 synchronous database transactions and 40/sec on an Android device is unfortunately pretty typical.
Here is my revised version (might need a few syntax changes)
public static void loadLocalPhoneBookSample(Context ctx) {
try {
ContentResolver contentRes = ctx.getContentResolver();
String selection = ContactsContract.Contacts.HAS_PHONE_NUMBER;
Cursor cur = contentRes.query(ContactsContract.Contacts.CONTENT_URI, PROJECTIONS, selection, null, Phone.DISPLAY_NAME + " ASC");

UpdateBuilder<ContactLocal, ?> updateDAO = contactDAO.updateBuilder();
try {
updateDAO.updateColumnValue("isUseless", true);
updateDAO.update();
} catch (SQLException e) {
e.printStackTrace();
}finally {
// db.writeUnlock();
}
ArrayList<ContactLocal> contacts = new ArrayList<>();
while (cur.moveToNext()) {
String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));

while (pCur.moveToNext()) {
String number = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
String formatedNo = number.replaceAll("\\s+", "").replace("+", "00").replace("-", "").trim();
try {
QueryBuilder<ContactLocal, ?> query = contactDAO.queryBuilder();
query.where().eq("mFormatedNumber", number);

contact.setContactNumber(formatedNo);
}
contact.setUseless(false);
contacts.add(contact);
}
}
pCur.close();
}
contactDao.callBatchTasks(new Callable<Void>() {
public Void call() throws Exception {
for (ContactLocal contact : contacts) {
contactDAO.createOrUpdate(contact);
}
}
});
}
}
The main optimization is to use callBatchTasks. From the ormlite documentation:
Databases by default commit changes after every SQL operation. This method disables this "auto-commit" behavior so a number of changes can be made faster and then committed all at once.
By creating an ArrayList and keeping track of the changes, you can use callBatchTasks to create/update at the end all in one shot.
Also I noticed that alreadyUpdated was never accessed, so it's safe to remove.
Also Dao has a createOrUpdate method which is the same as the addContact if statement you had before.
I'm trying to get mp3 files from a folder path of my system to list it in my listView, but unfortunately there's always the same error. (java.lang.NullPointerException: Attempt to get length of null array)
class Mp3Filter implements FilenameFilter{
public boolean accept(File dir, String name){
return (name.endsWith(".mp3"));
}
}
private static final String SD_PATH = new String(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MUSIC).toString());
public void searchForSongs() {
ListView listView;
listView = (ListView) findViewById(R.id.listView);
File f = new File(SD_PATH);
try {
if (f.listFiles(new Mp3Filter()).length > 0){
for (File file : f.listFiles(new Mp3Filter())){
list.add(file.getName());
}
}
}
catch(Exception e) {
textView2.setText(""+e);
return;
}
final ArrayAdapter songList = new ArrayAdapter(this, android.R.layout.simple_list_item_1, list);
listView.setAdapter(songList);
}
Here is your solution use the following code to Read the MP3 file from the Specific Folder..
First of all Create 1 Model class as Given Below, to GET and SET Files in list.
AudioModel.class
public class AudioModel {
String aPath;
String aName;
String aAlbum;
String aArtist;
public String getaPath() {
return aPath;
}
public void setaPath(String aPath) {
this.aPath = aPath;
}
public String getaName() {
return aName;
}
public void setaName(String aName) {
this.aName = aName;
}
public String getaAlbum() {
return aAlbum;
}
public void setaAlbum(String aAlbum) {
this.aAlbum = aAlbum;
}
public String getaArtist() {
return aArtist;
}
public void setaArtist(String aArtist) {
this.aArtist = aArtist;
}
}
Now We have our Model Class Now use the below code to Read the all MP3 files from your Folder.
This will return list of all MP3 Files with Music NAME, PATH, ARTIST, ALBUM and if you wants more detail please refer Media.Store.Audio doc..
https://developer.android.com/reference/android/provider/MediaStore.Audio.html
public List<AudioModel> getAllAudioFromDevice(final Context context) {
final List<AudioModel> tempAudioList = new ArrayList<>();
Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
String[] projection = {MediaStore.Audio.AudioColumns.DATA, MediaStore.Audio.AudioColumns.ALBUM, MediaStore.Audio.ArtistColumns.ARTIST,};
Cursor c = context.getContentResolver().query(uri, projection, MediaStore.Audio.Media.DATA + " like ? ", new String[]{"%yourFolderName%"}, null);
if (c != null) {
while (c.moveToNext()) {
AudioModel audioModel = new AudioModel();
String path = c.getString(0);
String album = c.getString(1);
String artist = c.getString(2);
String name = path.substring(path.lastIndexOf("/") + 1);
audioModel.setaName(name);
audioModel.setaAlbum(album);
audioModel.setaArtist(artist);
audioModel.setaPath(path);
Log.e("Name :" + name, " Album :" + album);
Log.e("Path :" + path, " Artist :" + artist);
tempAudioList.add(audioModel);
}
c.close();
}
return tempAudioList;
}
To Read Files of Specific Folder, use below Query and write your folder name in Query..
Cursor c = context.getContentResolver().query(uri,
projection,
MediaStore.Audio.Media.DATA + " like ? ",
new String[]{"%yourFolderName%"}, // yourFolderName
null);
If you wants All Files of device use below Query..
Cursor c = context.getContentResolver().query(uri,
projection,
null,
null,
null);
Don't forget to add Storage Permission .. enjoy.
