I am developing a simple audio streaming android app. While playing audios from the URLs, the app also has an option to download the file. The audio files are being downloaded in Internal Storage/voices folder. How can I show all the downloaded audios of this folder in my app? I want to access all the audios in voices folder and show in my app so the users don't need to search the files manually. Please guide. Thank you!
String path = Environment.getExternalStorageDirectory().toString()+"/voices";
Log.d("Files", "Path: " + path);
File directory = new File(path);
File[] files = directory.listFiles();
Log.d("Files", "Size: "+ files.length);
for (int i = 0; i < files.length; i++)
{
Log.d("Files", "FileName:" + files[i].getName());
}
This way you will get all the files stored in voices directory into files array.
I did it using the following code:
private ListView mainListView ;
private ArrayAdapter<String> listAdapter ;
private MediaPlayer mp = new MediaPlayer();
private List<String> ListOfFiles = new ArrayList<String>();
String path = Environment.getExternalStorageDirectory().toString()+"/voices";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Find the ListView resource.
mainListView = (ListView) findViewById( R.id.mainListView );
Log.d("Files", "Path: " + path);
File directory = new File(path);
File[] files = directory.listFiles();
Log.d("Files", "Size: "+ files.length);
for (int i = 0; i < files.length; i++)
{
Log.d("Files", "FileName:" + files[i].getName());
}
for (int i = 0; i < files.length; i++) {
ListOfFiles.add(files[i].getName());
}
listAdapter = new ArrayAdapter<String>(this, R.layout.row_layout, ListOfFiles);
mainListView.setAdapter( listAdapter );
mainListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
playSong(path +"/"+ ListOfFiles.get(position));
Log.d("Path",path + ListOfFiles.get(position));
}
});
}
private void playSong(String songPath) {
try {
mp.reset();
mp.setDataSource(songPath);
mp.prepare();
mp.start();
} catch (IOException e) {
Log.v(getString(R.string.app_name), e.getMessage());
}
}

I have set up code to display all folders that are on the SD card but now I am trying to figure out how to only display folders which contain MP3 files.
How can I filter out the folders that don't contain .MP3 files? thanks.
class:
public class FragmentFolders extends ListFragment {
private File file;
private List<String> myList;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
myList = new ArrayList<String>();
String root_sd = Environment.getExternalStorageDirectory().toString();
file = new File(root_sd);
File list[] = file.listFiles();
for (int i = 0; i < list.length; i++) {
myList.add(list[i].getName());
}
setListAdapter(new ArrayAdapter<String>(getActivity(),
android.R.layout.simple_list_item_1, myList));
}
public void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
File temp_file = new File(file, myList.get(position));
if (!temp_file.isFile()) {
file = new File(file, myList.get(position));
File list[] = file.listFiles();
myList.clear();
for (int i = 0; i < list.length; i++) {
myList.add(list[i].getName());
}
Toast.makeText(getActivity(), file.toString(), Toast.LENGTH_LONG)
.show();
setListAdapter(new ArrayAdapter<String>(getActivity(),
android.R.layout.simple_list_item_1, myList));
}
return;
}
}
You can check if the files within a directory are mp3 files before adding to your list view's dataset
Modify your code as follows:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
myList = new ArrayList<String>();
String root_sd = Environment.getExternalStorageDirectory().toString();
file = new File(root_sd);
//list content of root sd
File list[] = file.listFiles();
for (int i = 0; i < list.length; i++) {
//check the contents of each folder before adding to list
File mFile = new File(file, list[i].getName());
File dirList[] = mFile.listFiles();
if(dirList == null) continue;
for (int j = 0; j < dirList.length; j++) {
if(dirList[j].getName().toLowerCase(Locale.getDefault()).endsWith(".mp3")){
myList.add(list[i].getName());
break;
}
}
}
setListAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, myList));
}
I tested this and it works. Only caveat is, it doesn't check for sub-directories.
So in:
sdcard/Music/mistletoe.mp3
sdcard/Media/Tracks/mistletoe.mp3
only the Music folder will be listed.
Also, you may want to use an asyncTask to eschew hogging the UI thread
You can user a fileNameFilter and filter out the folders/files you don't want.
File baseDirectory = new File("/mnt/sdcard/"); //Your base dir here
File[] files = baseDirectory.listFiles(new FilenameFilter() {
#Override
public boolean accept(File dir, String fileName) {
File possibleMp3Folder = new File(dir, fileName);
if (possibleMp3Folder.isDirectory()) {
File[] files1 = possibleMp3Folder.listFiles();
for (File file : files1) {
if (file.getName().toLowerCase().endsWith(".mp3")) {
return true;
}
}
}
return false;
}
});
If you are looking for all folders contains mp3 files (both on Internal storage and SD Card) and available storages contains media:
Initialize two Sets for media storage paths and mp3 folders paths:
private HashSet<String> storageSet = new HashSet<>();
private HashSet<String> folderSet = new HashSet<>();
Get both in one method (you can return value if you need only one):
private void getMediaFolders() {
ContentResolver resolver = getContentResolver();
Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
String selection = MediaStore.Audio.Media.IS_MUSIC + " != 0";
String[] projection = { MediaStore.Audio.Media.DATA };
Cursor cursor = resolver.query(uri, projection, selection, null, null);
if(cursor != null && cursor.getCount() > 0) {
int dataIndex = cursor.getColumnIndex(MediaStore.Audio.Media.DATA);
while(cursor.moveToNext()) {
String data = cursor.getString(dataIndex);
int i = 0;
for (int slashCount = 0; i < data.length(); i++) {
if (data.charAt(i) == '/' && ++slashCount == 3) {
storageSet.add(data.substring(0, i));
break;
}
}
if (data.toLowerCase().endsWith("mp3")) {
int lastSlashIndex = data.lastIndexOf('/');
while (i < lastSlashIndex) {
data = data.substring(0, lastSlashIndex);
folderSet.add(data);
lastSlashIndex = data.lastIndexOf('/');
}
}
}
}
if (cursor != null) { cursor.close(); }
}
Filter folders (with Annimonstream):
private ArrayList<File> getFilteredFolders(#NonNull String path, HashSet<String> folderSet) {
File[] filesList = new File(path).listFiles();
if (filesList == null) { return new ArrayList<>(); } // Or handle error as you wish
return Stream.of(filesList)
.filter(File::isDirectory)
.filter(f -> folderSet.contains(f.getAbsolutePath()))
.collect(Collectors.toCollection(ArrayList::new));
}
Show storages (if needed).
Uri,Projection,
MediaStore.Video.Media.DATA
+ " like " + "'%.mp4%'"
+ " AND "
+ MediaStore.Video.Media.DATA
+ " like " + "'%" + getResources().
getString(R.string.string_store_video_folder)
+"%'", null,
MediaStore.Video.Media.DATE_MODIFIED
this will give mp4 files in a specific folder
I want to list all the files on the SD card. I use a this code for it:
myList = new ArrayList();
String root_sd = Environment.getExternalStorageDirectory().toString();
file = new File( "storage/" + root_sd ) ;
Log.e(myLog, file.getName());
File list[] = file.listFiles();
for( int i=0; i< list.length; i++)
{
myList.add( list[i].getName() );
Log.e(myLog, list[i].getName() + " : " + list[i].getTotalSpace());
}
And I get a nullPointerException for it after I log the name. I tried an other file also:
file = new File( root_sd ) ;
Ended with the same result.
So, how can I list the files properly? Thx for help!
...//initing the variables
String fileName = Environment.getExternalStorageDirectory().toString();
title.setText(fileName);
ArrayList<String> FilesInFolder = GetFiles(fileName);
mList.setAdapter(new ArrayAdapter<String>(getActivity() , android.R.layout.simple_list_item_1 , FilesInFolder));
mList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
// Clicking on items
}
});
and the function
public ArrayList<String> GetFiles(String DirectoryPath) {
ArrayList<String> MyFiles = new ArrayList<String>();
File f = new File(DirectoryPath);
f.mkdirs();
File[] files = f.listFiles();
if (files.length == 0)
return null;
else {
for (int i=0; i<files.length; i++)
MyFiles.add(files[i].getName());
}
return MyFiles;
}
If you want a different layout make an own ArrayAdapter
I am using a ListView the size of each cell is very small. I thought to increase size of text so that cell size will adjust automatically. but this didnt work.
My java code is as follows:
View v= findViewById(R.id.rowtext);
myPath = (TextView)findViewById(R.id.path);
root = Environment.getExternalStorageDirectory().getPath();
getDir(root);
}
public void bt_Quit(View v)
{
finish();
}
public void back(View v)
{
getDir(pos);
}
public void home(View v)
{
getDir(root);
}
private void getDir(String dirPath)
{
myPath.setText("Location: " + dirPath);
item = new ArrayList<String>();
path = new ArrayList<String>();
File f = new File(dirPath);
File[] files = f.listFiles();
pos=f.getParent();
if(!dirPath.equals(root))
{
}
for(int i=0; i < files.length; i++)
{
File file = files[i];
if(!file.isHidden() && file.canRead()){
path.add(file.getPath());
if(file.isDirectory()){
item.add(file.getName() + "/");
}else{
item.add(file.getName());
}
}
}
ArrayAdapter<String> fileList =
new ArrayAdapter<String>(this, R.layout.row, item);
setListAdapter(fileList);
}
The cellsize of List view is too small. What i want is to know how to adjust cellsize of listView?
change in your xml of listview
android:layout_width="20dp"
android:layout_height="30dp"
Change numbers according to ur need

Implement a ListView (follow this TUTORIAL).
Then implement a listener to handle the click on the items ( listView.onItemClickListener(); )
and then use the snipper below for the installation:
Intent promptInstall = new Intent(Intent.ACTION_VIEW)
.setData(Uri.parse("file:///path/to/your.apk"))
.setType("application/vnd.android.package-archive");
startActivity(promptInstall);

Please help, how to display the specified folder's contents, when click on a button by specifying the folder's full path.I tried like below, but My application crashes.
Button buttonFom = (Button) findViewById(R.id.fom);
buttonFom.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
getDir("/mnt/sdcard/external_sd/DOC1/HW 850Xp/");
}
});
private void getDir(String dirPath) {
myPath.setText("Location: " + dirPath);
item = new ArrayList<String>();
path = new ArrayList<String>();
File f = new File(dirPath);
File[] files = f.listFiles();
if (!dirPath.equals(root)) {
item.add(root);
path.add(root);
item.add("../");
path.add(f.getParent());
}
for (int i = 0; i < files.length; i++) {
File file = files[i];
path.add(file.getPath());
if (file.isDirectory())
item.add(file.getName() + "/");
else
item.add(file.getName());
}
ArrayAdapter<String> fileList = new ArrayAdapter<String>(this,
R.layout.row, item);
setListAdapter(fileList);
}
First you need to set user-permission to write access to SD card in Android Manifest file
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Without it you can't access to SD card
Hope, it's help you.
