On one of my device, the following code can't make my video appear in Gallery:
File file = new File(path);
Uri uri = Uri.fromFile(file);
Intent scanFileIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, uri);
activity.sendBroadcast(scanFileIntent);
So I use scanFile explicitly:
android.media.MediaScannerConnection.scanFile(activity, new String[]{file.getAbsolutePath()},
new String[]{"video/" + mMimeType}, null);
When my video is xxx.mpeg4, the value of mMimeType is mp4, the result is that the video can appear in MediaStore but I can't get the duration later(the returned value is always 0). Need help on this.
public static long[] getVideoDetail(Context context, Uri uri) {
long[] result = new long[] {DEFAULT_VIDEO_FRAME_WIDTH, DEFAULT_VIDEO_FRAME_HEIGHT, -1};
if(uri == null || (!ContentResolver.SCHEME_CONTENT.equals(uri.getScheme()))) {
return result;
}
String[] projection = new String[] {MediaStore.Video.Media.RESOLUTION, MediaStore.Video.VideoColumns.DURATION};
Cursor cursor = null;
boolean success = false;
try {
cursor = context.getContentResolver().query(uri, projection, null, null, null);
if (cursor.moveToFirst()) {
String resolution = cursor.getString(0);
if(!StringUtils.isEmpty(resolution)) {
int index = resolution.indexOf('x');
result[0] = Integer.parseInt(resolution.substring(0, index));
result[1] = Integer.parseInt(resolution.substring(index + 1));
if(result[0] != 0 && result[1] != 0) {
success = true;
}
if(result[0] > result[1]) {
swap(result, 0, 1);
}
}
result[2] = cursor.getLong(1);
if(result[2] >= 0 && success) {
success = true;
} else {
success = false;
}
}
if (null != cursor) {
cursor.close();
}
}
catch (Exception e) {
// do nothing
} finally {
try {
if (null != cursor) {
cursor.close();
}
} catch (Exception e2) {
// do nothing
}
}
if (!success) {
try {
ContentResolver contentResolver = context.getContentResolver();
String selection = MediaStore.Images.Media._ID + "= ?";
String id = uri.getLastPathSegment();
String[] selectionArgs = new String[]{ id };
cursor = contentResolver.query(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, projection, selection, selectionArgs, null);
if (cursor.moveToFirst()) {
String resolution = cursor.getString(0);
if(!StringUtils.isEmpty(resolution)) {
int index = resolution.indexOf('x');
result[0] = Integer.parseInt(resolution.substring(0, index));
result[1] = Integer.parseInt(resolution.substring(index + 1));
if(result[0] > result[1]) {
swap(result, 0, 1);
}
}
result[2] = cursor.getLong(1);
}
if (null != cursor) {
cursor.close();
}
} catch (Exception e) {
// do nothing
} finally {
try {
if (cursor != null) {
cursor.close();
}
} catch (Exception e) {
// do nothing
}
}
}
if(result[0] <= 0) {
result[0] = DEFAULT_VIDEO_FRAME_WIDTH;
}
if(result[1] <= 0) {
result[1] = DEFAULT_VIDEO_FRAME_HEIGHT;
}
return result;
}
As I see in your code you are requesting duration in your projection
String[] projection = new String[] {MediaStore.Video.Media.RESOLUTION, MediaStore.Video.VideoColumns.DURATION};
now you just need to retrieve it from the cursor like shown below:
long timeInMs = cursor.getLong(cursor.getColumnIndex(MediaStore.Video.VideoColumns.DURATION));
get help from MediaPlayer :
MediaPlayer mp = new MediaPlayer();
try {
mp.setDataSource(context, Uri.parse(uri));
} catch (IOException e) {
Log.d("-MS-","Cannot parse url");
e.printStackTrace();
}
int duration= mp.getDuration();
String[] projection = new String[] {MediaStore.Video.Media.RESOLUTION,duration};
I always get Duration by MediaPlayer.

I have built a rss news app. It is working fine upto some point with some bugs.

I am aware that media artwork is stored under albums and to get them you need to have the album id to access it. I have been able to get the images for tracks and albums using the album id.
However for artists table doesn't have the album id field. Other apps such as Play Music and Poweramp are somehow able to get the track artwork and add them to the respective artists.
How do i achieve this?
The way I do it is to get all albums for an artist and then use the rnd function to return an albumid:
String artist_id = c.getString(c.getColumnIndex(MediaStore.Audio.Artists._ID));
Cursor crs = album.getArtistsAlbumcursor(mContext, artist_id);
if(crs!=null && crs.moveToFirst()) {
Random rn = new Random();
int rnd = rn.nextInt( crs.getCount());
crs.moveToPosition(rnd);
album_id = crs.getLong(crs.getColumnIndex(MediaStore.Audio.Media.ALBUM_ID));
crs.close();
}
where getArtistsAlbumcursor is:
public Cursor getArtistsAlbumcursor(Context context, String artistId) {
ContentResolver cr = context.getContentResolver();
final String _id = MediaStore.Audio.Media._ID;
final String album_id = MediaStore.Audio.Media.ALBUM_ID;
final String artistid = MediaStore.Audio.Media.ARTIST_ID;
final String[] columns = { _id, album_id, artistid };
String where = artistid +" =?";
String[] aId = {artistId};
return cr.query(uri, columns, where, aId, null);
}
Once you have an albumid you can get your albumart using your original method.
Or
if you want to get the albumart from the mp3 track itself, you will need to implement a libary such as jaudiotagger or org.blinkenlights.jid3.v2.
Life gets a little more complicated but below how to get albumart from the mp3 tag using the JID3 library:
try {
bmp = getmp3AlbumArt(sourceFile);
} catch (Exception e) {
e.printStackTrace();
}
where getmp3Albumart is:
public Bitmap getmp3AlbumArt(File SourceFile) throws Exception {
Bitmap bmp = null;
arrayByte = null;
APICID3V2Frame frames[];
MediaFile MediaFile = new MP3File(SourceFile);
try {
Object obj = null;
obj = MediaFile.getID3V2Tag();
if (obj != null) {
tagImage = (org.blinkenlights.jid3.v2.ID3V2_3_0Tag) obj;
if ((tagImage != null) && (arrayByte == null) && (tagImage.getAPICFrames() != null) && (tagImage.getAPICFrames().length > 0)) {
frames = tagImage.getAPICFrames();
for (int i = 0; i < tagImage.getAPICFrames().length; i++) {
if (frames[i] != null) {
arrayByte = frames[i].getPictureData();
break;
}
}
}
}
} catch (ID3Exception | OutOfMemoryError e) {
e.printStackTrace();
}
if (arrayByte != null) {
try {
bmp = BitmapFactory.decodeByteArray(arrayByte, 0, arrayByte.length);
} catch (Exception|OutOfMemoryError e) {
e.printStackTrace();
}
}
return bmp;
}
Can someone help me to create a reminder for an calendar event on programmatically. It works perfectly fine on API level 22, but not on 23 (Marshmallow).

I am new to android programming so can anyone please help me to find all .mp3 files in my android device.
You should use MediaStore. Here is an example code i'm using for something similar:
private static ArrayList<SongModel> LoadSongsFromCard() {
ArrayList<SongModel> songs = new ArrayList<SongModel>();
// Filter only mp3s, only those marked by the MediaStore to be music and longer than 1 minute
String selection = MediaStore.Audio.Media.IS_MUSIC + " != 0"
+ " AND " + MediaStore.Audio.Media.MIME_TYPE + "= 'audio/mpeg'"
+ " AND " + MediaStore.Audio.Media.DURATION + " > 60000";
final String[] projection = new String[] {
MediaStore.Audio.Media._ID, //0
MediaStore.Audio.Media.TITLE, //1
MediaStore.Audio.Media.ARTIST, //2
MediaStore.Audio.Media.DATA, //3
MediaStore.Audio.Media.DISPLAY_NAME
};
final String sortOrder = MediaStore.Audio.AudioColumns.TITLE
+ " COLLATE LOCALIZED ASC";
Cursor cursor = null;
try {
// the uri of the table that we want to query
Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI; //getContentUriForPath("");
// query the db
cursor = _context.getContentResolver().query(uri,
projection, selection, null, sortOrder);
if (cursor != null) {
cursor.moveToFirst();
while (!cursor.isAfterLast()) {
//if (cursor.getString(3).contains("AwesomePlaylists")) {
SongModel GSC = new SongModel();
GSC.ID = cursor.getLong(0);
GSC.songTitle = cursor.getString(1);
GSC.songArtist = cursor.getString(2);
GSC.path = cursor.getString(3);
// This code assumes genre is stored in the first letter of the song file name
String genreCodeString = cursor.getString(4).substring(0, 1);
if (!genreCodeString.isEmpty()) {
try {
GSC.genre = Short.parseShort(genreCodeString);
} catch (NumberFormatException ex) {
Random r = new Random();
GSC.genre = (short) r.nextInt(4);
} finally {
songs.add(GSC);
}
}
//}
cursor.moveToNext();
}
}
} catch (Exception ex) {
} finally {
if (cursor != null) {
cursor.close();
}
}
return songs;
}
Of course . you can . Code not tested.
File dir =new File(Environment.getExternalStorageDirectory());
if (dir.exists()&&dir.isDirectory()){
File[] files=dir.listFiles(new FilenameFilter(){
#Override
public boolean accept(File dir,String name){
return name.contains(".mp3");
}
});
}
You can use recursive searching. Use this function with path of directory where you wanna start search .mp3 files (for example "/mnt/sdcard").
public Vector<String> mp3Files = new Vector<String>();
private void searchInDirectory(String directory)
{
File dir = new File(directory);
if(dir.canRead() && dir.exists() && dir.isDirectory())
{
String []filesInDirectory = dir.list();
if(filesInDirectory != null)
{
for(int i=0; i<filesInDirectory.length; i++)
{
File file = new File(directory+"/"+filesInDirectory[i]);
if(file.isFile() && file.getAbsolutePath().toLowerCase(Locale.getDefault()).endsWith(".mp3"))
{
mp3Files.add(directory+"/"+filesInDirectory[i]);
}
else if(file.isDirectory() )
{
searchInDirectory(file.getAbsolutePath());
}
}
}
}
}
public ArrayList<String> searchMP3File(ArrayList<String> aListFilePath, String rootPath) {
File rootFile = new File(rootPath);
File[] aRootFileFilter = rootFile.listFiles(new FileFilter() {
#Override
public boolean accept(File pathname) {
if(pathname.getName().endsWith(".mp3"))
return true;
else
return false;
}
});
if(aRootFileFilter != null && aRootFileFilter.length > 0) {
for(int i = 0; i < aRootFileFilter.length; i++) {
aListFilePath.add(aRootFileFilter[i].getPath());
}
}
File[] aRootFile = rootFile.listFiles();
for(int i = 0; i < aRootFile.length; i++) {
if(aRootFile[i].isDirectory()) {
ArrayList<String> aListSubFile = searchMP3File(aListFilePath, aRootFile[i].getPath());
if(aListSubFile != null && aListSubFile.size() > 0)
aListFilePath = aListSubFile;
}
}
return aListFilePath;
}
private String[] videoExtensions;
videoExtensions = new String[2];

After this declaration in your onCreate() method, set below code in some method and call it. Do changes as per your need in my code.
try {

videoHashmap = new HashMap<String, String>();
for (int i = videoIndex; i < listOfFiles.length; i++) {
File files = listOfFiles[i];
rowDataVideos = new HashMap<String, String>();
for (String ext : videoExtensions) {
if (files.getName().endsWith("." + ext)) {
videoHashmap.put("Video", files.getAbsolutePath());
videoArray.add(videoHashmap);
fileSize = files.length();
fileSizeInMb += convertSize(fileSize, MB);
thumb = ThumbnailUtils.createVideoThumbnail(files.getAbsolutePath(), MediaStore.Images.Thumbnails.MINI_KIND);
if (thumb != null) {
createTempDirectory();
try {
FileOutputStream out = new FileOutputStream(audiofile);
thumb.compress(Bitmap.CompressFormat.PNG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}

lastModDate = new Date(files.lastModified()).toString();
dateTime = (dateToMilliSeconds(lastModDate) / 1000L);
rowDataVideos.put(VIDEOPATH, files.getAbsolutePath());
rowDataVideos.put(VIDEOSTATUS, "0");
rowDataVideos.put(VIDEOSIZEINMB, String.valueOf(fileSizeInMb));
rowDataVideos.put(VIDEODATE, String.valueOf(dateTime));
if (dateTime > (RESPONSE_TIMESTAMP_VIDEO / 1000L)) {
dataProvider.InsertRow(VIDEOS, rowDataVideos);

I am trying to read all the images in the SDCARD with the Directory in which its present. e.g: if there is a file TEST.jpg in /mnt/sdcard/album1 and TEST2.jpg in /mnt/sdcard/album1/album2 i should be able to get the directory name album1 and album2.
I have written a code which does this in recursive manner, This works when the no of folders are less but when the number of directories increases the loop just come out of it.
public void getImageFoldes(String filepath){
String albumpath;
File file = new File(filepath);
File[] files = file.listFiles();
for (int fileInList = 0; fileInList < files.length; fileInList++)

File filename;
filename =files[fileInList];
if(filename.isHidden()|| filename.toString().startsWith("."))
return;
if (filename.isDirectory()){
albumpath = filename.toString();
String[] split;
String title;
split= albumpath.split("/");
title=split[split.length-1];
result = new thumbnailResults();
result.setTitle(title);
result.setPath(albumpath);
result.setIsLocal(true);
//result.setCreated("05-06-2011");
getImageFoldes(filename.toString());
}
else{
if (files.length !=0)
{
//if File is the image file then store the album name
if ((files[fileInList].toString()).contains(".png")||
(files[fileInList].toString()).contains(".jpg")||
(files[fileInList].toString()).contains(".jpeg")){
if (!results.contains(result)){
result.setUri(Uri.parse(files[fileInList].getPath()));
results.add(result);
myadapter.notifyDataSetChanged();

Use the following code.
to get the path of all images and directories from sdcard.
public static ArrayList<String> getPathOfAllImages(Activity activity) {
ArrayList<String> absolutePathOfImageList = new ArrayList<String>();
String absolutePathOfImage = null;
String nameOfFile = null;
String absolutePathOfFileWithoutFileName = null;
Uri uri;
Cursor cursor;
int column_index;
int column_displayname;
int lastIndex;
// absolutePathOfImages.clear();
uri = android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
String[] projection = { MediaColumns.DATA,
MediaColumns.DISPLAY_NAME };
cursor = activity.managedQuery(uri, projection, null, null, null);
column_index = cursor.getColumnIndexOrThrow(MediaColumns.DATA);
column_displayname = cursor
.getColumnIndexOrThrow(MediaColumns.DISPLAY_NAME);
// cursor.moveToFirst();
while (cursor.moveToNext()) {
// for(int i=0; i<cursor.getColumnCount();i++){
// Log.i(TAG,cursor.getColumnName(i)+".....Data Present ...."+cursor.getString(i));
// }
// Log.i(TAG,"=====================================");
absolutePathOfImage = cursor.getString(column_index);
nameOfFile = cursor.getString(column_displayname);
lastIndex = absolutePathOfImage.lastIndexOf(nameOfFile);
lastIndex = lastIndex >= 0 ? lastIndex
: nameOfFile.length() - 1;
absolutePathOfFileWithoutFileName = absolutePathOfImage
.substring(0, lastIndex);
if (absolutePathOfImage != null) {
absolutePathOfImageList.add(absolutePathOfImage);
}
}
// Log.i(TAG,"........Detected images for Grid....."
// + absolutePathOfImageList);
return absolutePathOfImageList;
}
To get all the image files from the Sdcard, it may work.
