I am using native Android camera and save file to my application data folder (/mnt/sdcard/Android/data/com.company.app/files/Pictures/). At the same time anther copy of photo is saved to DCIM folder.
This is my code:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
String formattedImageName = getDateString() + ".jpg";
File image_file = new File(this.getExternalFilesDir(Environment.DIRECTORY_PICTURES), formattedImageName);
Uri imageUri = Uri.fromFile(image_file);
intent.putExtra(MediaStore.EXTRA_OUTPUT,imageUri);
startActivityForResult(intent, REQUEST_FROM_CAMERA);
How can I prevent saving additional copy of image to DCIM folder?
Many Thanks
You can use the following :
First we get the last saved image by checking which was the last modified image. Then check if last modified time is in the last few seconds. You may also have to check the exact location of where camera stores the image.
private boolean deleteLastFromDCIM() {
boolean success = false;
try {
File[] images = new File(Environment.getExternalStorageDirectory()
+ File.separator + "DCIM/Camera").listFiles();
File latestSavedImage = images[0];
for (int i = 1; i < images.length; ++i) {
if (images[i].lastModified() > latestSavedImage.lastModified()) {
latestSavedImage = images[i];
}
}
// OR JUST Use success = latestSavedImage.delete();
success = new File(Environment.getExternalStorageDirectory()
+ File.separator + "DCIM/Camera/"
+ latestSavedImage.getAbsoluteFile()).delete();
return success;
} catch (Exception e) {
e.printStackTrace();
return success;
}
}
Unfortunately, some smart phones save images in another folder such as DCIM/100MEDIA. So can't rely to these solution. I prefer use this way:
String[] projection = new String[] {
MediaStore.Images.ImageColumns._ID,
MediaStore.Images.ImageColumns.DATA,
MediaStore.Images.ImageColumns.BUCKET_DISPLAY_NAME,
MediaStore.Images.ImageColumns.DATE_TAKEN,
MediaStore.Images.ImageColumns.MIME_TYPE};
final Cursor cursor = managedQuery(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,projection, null, null,
MediaStore.Images.ImageColumns.DATE_TAKEN + " DESC");
if(cursor != null){
cursor.moveToFirst();
// you will find the last taken picture here and can delete that
}
I tried to find out if a second copy exists and delete the copy. I used the above code to find the last taken picture.
Notice: Don't use cursor.close(); after using managedQuery, Leave the cursor for the Android system to manage and don't call that. You can see managedQuery()
Notice2: The managedQuery method is deprecated and it should be avoided, implement CursorLoaders instead.
check this code..
private void FillPhotoList() {
// initialize the list!
GalleryList.clear();
String[] projection = { MediaStore.Images.ImageColumns.DISPLAY_NAME };
for(int i=0;i<projection.length;i++)
Log.i("InfoLog","projection "+projection[0].toString());
// intialize the Uri and the Cursor, and the current expected size.
Cursor c = null;
Uri u = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
Log.i("InfoLog","FillPhoto Uri u "+u.toString());
// Query the Uri to get the data path. Only if the Uri is valid.
if (u != null)
{
c = managedQuery(u, projection, null, null, null);
}
// If we found the cursor and found a record in it (we also have the id).
if ((c != null) && (c.moveToFirst()))
{
do
{
// Loop each and add to the list.
GalleryList.add(c.getString(0)); // adding all the images sotred in the mobile phone(Internal and SD card)
}
while (c.moveToNext());
}
Log.i(INFOLOG,"gallery size "+ GalleryList.size());
}
and this is where the method is doing all magic
/** Method will check all the photo is the gallery and delete last captured and move it to the required folder.
*/
public void movingCapturedImageFromDCIMtoMerchandising()
{
// This is ##### ridiculous. Some versions of Android save
// to the MediaStore as well. Not sure why! We don't know what
// name Android will give either, so we get to search for this
// manually and remove it.
String[] projection = { MediaStore.Images.ImageColumns.SIZE,
MediaStore.Images.ImageColumns.DISPLAY_NAME,
MediaStore.Images.ImageColumns.DATA,
BaseColumns._ID,};
// intialize the Uri and the Cursor, and the current expected size.
for(int i=0;i<projection.length;i++)
Log.i("InfoLog","on activityresult projection "+projection[i]);
//+" "+projection[1]+" "+projection[2]+" "+projection[3] this will be needed if u remove the for loop
Cursor c = null;
Uri u = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
Log.i("InfoLog","on activityresult Uri u "+u.toString());
if (CurrentFile != null)
{
// Query the Uri to get the data path. Only if the Uri is valid,
// and we had a valid size to be searching for.
if ((u != null) && (CurrentFile.length() > 0))
{
//****u is the place from data will come and projection is the specified data what we want
c = managedQuery(u, projection, null, null, null);
}
// If we found the cursor and found a record in it (we also have the size).
if ((c != null) && (c.moveToFirst()))
{
do
{
// Check each area in the gallery we built before.
boolean bFound = false;
for (String sGallery : GalleryList)
{
if (sGallery.equalsIgnoreCase(c.getString(1)))
{
bFound = true;
Log.i("InfoLog","c.getString(1) "+c.getString(1));
break;
}
}
// To here we looped the full gallery.
if (!bFound) //the file which is newly created and it has to be deleted from the gallery
{
// This is the NEW image. If the size is bigger, copy it.
// Then delete it!
File f = new File(c.getString(2));
// Ensure it's there, check size, and delete!
if ((f.exists()) && (CurrentFile.length() < c.getLong(0)) && (CurrentFile.delete()))
{
// Finally we can stop the copy.
try
{
CurrentFile.createNewFile();
FileChannel source = null;
FileChannel destination = null;
try
{
source = new FileInputStream(f).getChannel();
destination = new FileOutputStream(CurrentFile).getChannel();

finally

A nice solution by Parth. But it's good for Samsungs that keep images in DCIM/Camera. Some phones - Sony Ericssons, HTCs keep them in folders like DCIM/100MEDIA, DCIM/100ANDRO so I have slightly modified the code:
private boolean deleteLastFromDCIM() {
boolean success = false;
try {
//Samsungs:
File folder = new File(Environment.getExternalStorageDirectory() + File.separator + "DCIM/Camera");
if(!folder.exists()){ //other phones:
File[] subfolders = new File(Environment.getExternalStorageDirectory() + File.separator + "DCIM").listFiles();
for(File subfolder : subfolders){
if(subfolder.getAbsolutePath().contains("100")){
folder = subfolder;
break;
}
}
if(!folder.exists())
return false;
}
File[] images = folder.listFiles();
File latestSavedImage = images[0];
for (int i = 1; i < images.length; ++i) {
if (images[i].lastModified() > latestSavedImage.lastModified()) {
latestSavedImage = images[i];
}
}
success = latestSavedImage.delete();
return success;
} catch (Exception e) {
e.printStackTrace();
return success;
}
}
I am encountering a similar problem with the Moto Z Force (7.1.1). I have the MediaStore.EXTRA_OUTPUT defined on the intent, but a duplicate file is still created in the camera directory.
I need to test on other devices, but here's an approach I took regarding this issue. Rather than trying to find the specific camera directory, I'm using the MediaStore.Images.ImageColumns.BUCKET_DISPLAY_NAME location.
Here's my code snippet:
private void removeCameraDuplicate() {
String[] proj = {
MediaStore.Images.ImageColumns.DATA,
MediaStore.Images.ImageColumns._ID };
String selection = MediaStore.Images.ImageColumns.BUCKET_DISPLAY_NAME + " = ? ";
String[] selectionArgs = new String[] { "Camera" };
Cursor cursor = mActivity.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, proj, selection, selectionArgs, MediaStore.Images.ImageColumns.DATE_TAKEN + " desc");
if (cursor != null) {
int idxPath = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
if (cursor.getCount() > 0 && idxPath > -1 && cursor.moveToFirst()) {
File original = new File(mMediaPath);
File cameraDupe = new File(cursor.getString(idxPath));
if (original.exists() && cameraDupe.exists()) {
LogUtils.LOGE("***> camera", "original " + original.length());
LogUtils.LOGE("***> camera", "original " + original.lastModified());
LogUtils.LOGE("***> camera", "duplicate " + cameraDupe.length());
LogUtils.LOGE("***> camera", "duplicate " + cameraDupe.lastModified());
if (original.length() == cameraDupe.length() && original.lastModified() == cameraDupe.lastModified()) {
if (cameraDupe.delete()) {
LogUtils.LOGE("***> camera", "duplicate deleted");
}
}
}
}
cursor.close();
}
}

On Android 11, when trying to remove multiple tracks from a Playlist, all the tracks are removed instead of just the selected ones. This used to work fine till Android 10.
However, if only 1 track is removed, no other tracks are removed. Is this a bug or an expected behavior going forward from Android 11? Is this a side-effect of scoped storage?
Tested on : Pixel 3, Android 11 Official release build
public void removeTracksFromPlaylist(long playlistId, String[] ids) {
Log.d(TAG, "removeTracksFromPlaylist() called with: playlistId = [" + playlistId + "], ids = [" + Arrays.toString(ids) + "]");
Uri uri = MediaStore.Audio.Playlists.Members.getContentUri(MediaStore.VOLUME_EXTERNAL, playlistId);
StringBuilder stringBuilder = new StringBuilder();
for (int index = 0; index < ids.length; index++) {
if (index > 0) {
stringBuilder.append(",");
}
stringBuilder.append("?");
}
String selection = MediaStore.Audio.Playlists.Members._ID + " IN (" + stringBuilder.toString() + ")";
contentResolver.delete(uri, selection, ids); // Returns count of all files removed from playlist
}
Edit:
Some information from source : (https://android.googlesource.com/platform/packages/providers/MediaProvider/+blame/refs/tags/android-11.0.0_r3/src/com/android/providers/media/MediaProvider.java#5610)
From the source, I see that if the count of playlist items are more than 1, the whole playlist is cleared.
try (Cursor c = qb.query(helper,
new String[] { Playlists.Members.PLAY_ORDER }, queryArgs, null)) {
if ((c.getCount() == 1) && c.moveToFirst()) { // This condition fails if more than 1 item to delete
return c.getInt(0) - 1;
} else {
return -1;
}
}
The index is used here which clears the playlist:(https://android.googlesource.com/platform/packages/providers/MediaProvider/+blame/refs/tags/android-11.0.0_r3/src/com/android/providers/media/MediaProvider.java#5566)
private int removePlaylistMembers(#NonNull Uri playlistUri, #NonNull Bundle queryArgs)

final Playlist playlist = new Playlist();
playlist.read(playlistFile);
final int count;
if (index == -1) {
count = playlist.asList().size();
playlist.clear(); //Clears whole playlist
} else {
count = 1;
playlist.remove(index);
}
playlist.write(playlistFile);
resolvePlaylistMembers(playlistUri);
return count;

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;
}

I'm new to android development and I have my way around drawables. I am now trying to achieve access to an external folder(from SD card) and load the images into an array of int so I could use them. However, after some research around S.O I still can't find something that can help me.
Currently I am putting images(*.jpg) from my Drawable folder and I have them in an array as follows:
int[] image = { R.drawable.location, R.drawable.diversity, R.drawable.classes, R.drawable.activities, R.drawable.sports, R.drawable.friends,
R.drawable.graduate};
How can I load images from an external folder into something similar like the array above? The problem here is with the images names. How will I actually get the image names when I load them from that external folder(assuming it contains only images)?
Any help would be greatly appreciated.
Thanks.
following method will return you path of all image from your device , get these path , and use them to show image

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){

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{

}
}

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;

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);

absolutePathOfImageList.add(absolutePathOfImage);
}
}
// Log.i(TAG,"........Detected images for Grid....."

To get all the image files from the Sdcard, it may work.
