I need to get the uri/paths of all the images taken by the camera (gallery). How can I modify the code below to give me only the images from the gallery. The code below gives me images from other folders too.
public ArrayList<String> getImages()
{
ArrayList<String> paths = new ArrayList<String>();
final String[] columns = { MediaStore.Images.Media.DATA, MediaStore.Images.Media._ID };
final String orderBy = MediaStore.Images.Media.DATE_ADDED;
//Stores all the images from the gallery in Cursor
Cursor cursor = getContentResolver().query(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, columns, null,
null, orderBy);
//Total number of images
int count = cursor.getCount();
//Create an array to store path to all the images
String[] arrPath = new String[count];
for (int i = 0; i < count; i++) {
cursor.moveToPosition(i);
int dataColumnIndex = cursor.getColumnIndex(MediaStore.Images.Media.DATA);
//Store the path of the image
arrPath[i]= cursor.getString(dataColumnIndex);
paths.add(arrPath[i]);
}
return paths;
}
Just provide the selection argument in query
public ArrayList<String> getImages()
{
ArrayList<String> paths = new ArrayList<String>();
final String[] columns = { MediaStore.Images.Media.DATA, MediaStore.Images.Media._ID };
String selection = MediaStore.Images.Media.BUCKET_DISPLAY_NAME + " = ?";
String[] selectionArgs = new String[] {
"Camera"
};
final String orderBy = MediaStore.Images.Media.DATE_ADDED;
//Stores all the images from the gallery in Cursor
Cursor cursor = getContentResolver().query(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, columns, selection, selectionArgs, orderBy);
//Total number of images
int count = cursor.getCount();
//Create an array to store path to all the images
String[] arrPath = new String[count];
for (int i = 0; i < count; i++) {
cursor.moveToPosition(i);
int dataColumnIndex = cursor.getColumnIndex(MediaStore.Images.Media.DATA);
//Store the path of the image
arrPath[i]= cursor.getString(dataColumnIndex);
paths.add(arrPath[i]);
}
return paths;
}

I just want to query only images from DCIM folder. How can I setup cursor query to do it?
This query will return all images from all folder in Android
doing a query with MediaStore.Images.Media does not show all images whether it is querying internal content or external content
The results (the thumbnails and the location those thumbnails are retrieved from) are not the same across even mainstream devices. Devices with no SD card and only internal storage have different image results, Samsung devices have different kinds of results, Google devices have different kinds of results.
Specifically with this code that is used around stackoverflow as a solution,
final String[] columns = {MediaStore.Images.Thumbnails._ID};
final String orderBy = MediaStore.Images.Media._ID;
Cursor imagecursor = context.getContentResolver().query(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, columns,
null, null, orderBy);
if (imagecursor != null) {
int image_column_index = imagecursor
.getColumnIndex(MediaStore.Images.Media._ID);
int count = imagecursor.getCount();
for (int i = 0; i < count; i++) {
imagecursor.moveToPosition(i);
int id = imagecursor.getInt(image_column_index);
ImageItem imageItem = new ImageItem();
imageItem.id = id;
lastId = id;
imageItem.img = MediaStore.Images.Thumbnails.getThumbnail(
context.getApplicationContext().getContentResolver(), id,
MediaStore.Images.Thumbnails.MINI_KIND, null);
images.add(imageItem);
}
imagecursor.close();
I look at the code and it seems sound, but I need a better solution because results vary, and on some devices I have no idea where the resulting thumbnails have been pulled from
As #danny117 pointed out to me, trying to get THUMBNAILS was a flawed assumption. One cannot rely on the existence of thumbnails for every image in the android system.
So I ultimately retrieve all images based on mime type, and use the Files MediaStore
String[] projection = {
MediaStore.Files.FileColumns._ID,
MediaStore.Files.FileColumns.DATA,
MediaStore.Files.FileColumns.DATE_ADDED,
MediaStore.Files.FileColumns.MEDIA_TYPE,
MediaStore.Files.FileColumns.MIME_TYPE,
MediaStore.Files.FileColumns.TITLE
};
// Return only video and image metadata.
String selection = MediaStore.Files.FileColumns.MEDIA_TYPE + "="
+ MediaStore.Files.FileColumns.MEDIA_TYPE_IMAGE
+ " OR "
+ MediaStore.Files.FileColumns.MEDIA_TYPE + "="
+ MediaStore.Files.FileColumns.MEDIA_TYPE_VIDEO;
Uri queryUri = MediaStore.Files.getContentUri("external");
CursorLoader cursorLoader = new CursorLoader(
getActivity(),
queryUri,
projection,
selection,
null, // Selection args (none).
MediaStore.Files.FileColumns.DATE_ADDED + " DESC" // Sort order.
);
images.clear();
/*
final String[] columns = {MediaStore.Images.ImageColumns._ID, MediaStore.Images.ImageColumns.DATE_ADDED};
final String orderBy = MediaStore.Images.Media.DATE_ADDED + " DESC";
Cursor imagecursor = getActivity().getContentResolver().query(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, columns,
null, null, orderBy);
*/
Cursor imagecursor = cursorLoader.loadInBackground();
if (imagecursor != null) {
int image_column_index = imagecursor
.getColumnIndex(MediaStore.Files.FileColumns._ID);
int type_column_index = imagecursor.getColumnIndex(MediaStore.Files.FileColumns.MIME_TYPE);
int count = imagecursor.getCount();
for (int i = 0; i < count; i++) {
imagecursor.moveToPosition(i);
int id = imagecursor.getInt(image_column_index);
String mime_type = imagecursor.getString(type_column_index);
ImageItem imageItem = new ImageItem();
imageItem.id = id;
//lastId = id;
if(!mime_type.contains("video"))
imageItem.uriString = MediaStore.Images.Media.EXTERNAL_CONTENT_URI.withAppendedPath(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, String.valueOf(id)).toString();
else
imageItem.uriString = MediaStore.Video.Media.EXTERNAL_CONTENT_URI.withAppendedPath(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, String.valueOf(id)).toString();
images.add(imageItem);
}
//add ImageItem at top of list
imagecursor.close();
}
I am trying to fetch all the photos of my android device.
I have an onCreate function:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ImageAdapter adapter= new ImageAdapter(this);
final String[] columns = { MediaStore.Images.Media.DATA, MediaStore.Images.Media._ID };
final String orderBy = MediaStore.Images.Media._ID;
Uri rr= MediaStore.Images.Media.INTERNAL_CONTENT_URI;
Cursor imagecursor = getContentResolver().query(
MediaStore.Images.Media.INTERNAL_CONTENT_URI,null, null,
null, orderBy);
int image_column_index = imagecursor.getColumnIndex(MediaStore.Images.Media._ID);
this.count = imagecursor.getCount();
this.thumbnails = new Bitmap[this.count];
for (int i = 0; i < this.count; i++) {
imagecursor.moveToPosition(i);
int id = imagecursor.getInt(image_column_index);
thumbnails[i] = MediaStore.Images.Thumbnails.getThumbnail(
getApplicationContext().getContentResolver(), id,
MediaStore.Images.Thumbnails.MICRO_KIND, null);
adapter.mThumbIds[i]= thumbnails[i];
}
}
where the count returned on imageCursor.getCount() is returning 0.
Can someone please guide me since I am not able to fetch any media using this code?
Note: I am testing on Galaxy Note-2
First do not forget to
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
This method will return list of photo in your gallery
public static ArrayList<String> getImagesPath(Activity activity) {
Uri uri;
ArrayList<String> listOfAllImages = new ArrayList<String>();
Cursor cursor;
int column_index_data, column_index_folder_name;
String PathOfImage = null;
uri = android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
String[] projection = { MediaColumns.DATA,
MediaStore.Images.Media.BUCKET_DISPLAY_NAME };
cursor = activity.getContentResolver().query(uri, projection, null,
null, null);
column_index_data = cursor.getColumnIndexOrThrow(MediaColumns.DATA);
column_index_folder_name = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.BUCKET_DISPLAY_NAME);
while (cursor.moveToNext()) {
PathOfImage = cursor.getString(column_index_data);
listOfAllImages.add(PathOfImage);
}
return listOfAllImages;
}
just give it a try even if your device has only internal storage no external storage,
try adding permissions:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
and read using
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
Anyone know how to get a listing of all images that show up in the Android Gallery?
This query is only gets pictures taken locally on the phone. Does anyone know the URI where the Picasa image database is stored?? Appreciate the help.
private void getListOfAllPictures()
{
final String[] filePathColumn = { MediaStore.Images.Media._ID, MediaColumns.DATA, MediaColumns.DISPLAY_NAME, Images.Media.ORIENTATION, Images.Media.LATITUDE, Images.Media.LONGITUDE };
Cursor cursor = getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
filePathColumn, null, null, null);
Vector<ImageDescriptor> imageDescriptors = new Vector<ImageDescriptor>();
if(cursor != null)
{
cursor.moveToFirst();
int IMG_ID_INDEX = cursor.getColumnIndex(MediaStore.Images.Media._ID);
int DATA_INDEX = cursor.getColumnIndex(MediaColumns.DATA);
int LATITUDE_INDEX = cursor.getColumnIndex(Images.Media.LATITUDE);
int LONGITUDE_INDEX = cursor.getColumnIndex(Images.Media.LONGITUDE);
int ORIENTATION_INDEX = cursor.getColumnIndex(Images.Media.ORIENTATION);
while(!cursor.isAfterLast())
{
//Blah Blah
cursor.moveToNext();
}
}
cursor.close();
Log.v(TAG, "Found " + imageDescriptors.size() + " images.");
}
ok its my code and it work for me it give all images which i can see in Android Gallery
just call this function from this line
getallimages(Environment.getExternalStorageDirectory());
and my function is below
private void getallimages(File dir)
{
String[] STAR = { "*" };
final String orderBy = MediaStore.Images.Media.DEFAULT_SORT_ORDER;
Cursor imagecursor = cntx.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, STAR, null, null, orderBy);
int image_column_index = imagecursor.getColumnIndex(MediaStore.Images.Media.DATA);
int count = imagecursor.getCount();
for (int i = 0; i < count; i++) {
imagecursor.moveToPosition(i);
int id = imagecursor.getInt(image_column_index);
ImageItem imageItem = new ImageItem();
imageItem.filePath = imagecursor.getString(imagecursor.getColumnIndex(MediaStore.Images.Media.DATA));
imageItem.id = id;
imageItem.selection = false; //newly added item will be selected by default
controller.images.add(imageItem);
}
}
First, I use below ode to get all image path.
And save to string array path.
String[] projection = {MediaStore.Images.Media._ID, MediaStore.Images.Media.DATA, MediaStore.Images.ImageColumns.DATA};
Cursor cursor = managedQuery( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, projection, null, null, MediaStore.Images.Media._ID);
int count = cursor.getCount();
int image_column_index = cursor.getColumnIndex(MediaStore.Images.Media._ID);
int image_path_index = cursor.getColumnIndex(MediaStore.Images.Media.DATA);
int i;
for(i = 0; i < count; i++) {
cursor.moveToPosition(i);
int id = cursor.getInt(image_column_index);
pat[i[ = cursor.getString(image_path_index);
}
After finish, I try below code to get thumbnail.
int i;
for(i = 0; i < count; i++) {
String[] projection = {MediaStore.Images.Media._ID, MediaStore.Images.Media.DATA};
Cursor cursor = act.managedQuery( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, projection, MediaStore.Images.Media.DATA + "=?", new String[] {path[i]}, MediaStore.Images.Media._ID); }
But while the file number very large(about 1000 files), the cursor show null.
I confirm it not cause by path name.
Any other reason?
The second try add cursor.close();
As below:
int i;
for(i = 0; i < count; i++) {
String[] projection = {MediaStore.Images.Media._ID, MediaStore.Images.Media.DATA};
Cursor cursor = act.managedQuery( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, projection, MediaStore.Images.Media.DATA + "=?", new String[] {path[i]}, MediaStore.Images.Media._ID);
cursor.close();
}
