Image, Saved to Sdcard, Doesn't Appear in Android's Gallery App

Image, saved to sdcard, doesn't appear in Android's Gallery app

The system scans the SD card when it is mounted to find any new image (and other) files. If you are programmatically adding a file, then you can use this class:

Android - Why my saved image is not appearing in the default gallery of my phone?

I haven't tried this, but I believe you need to run the Media Scanner to scan the internal storage directory so that the gallery can see your newly saved image. Check this post here.

images not showing in gallery app after inserting to sd card

I have also faced same problem..Have you tried this ??

File imageFile = ...
MediaScannerConnection.scanFile(this, new String[] { imageFile.getPath() }, new String[] { "image/jpeg" }, null);

Android - Saved image in external storage doesn't appear in gallery

The MediaStore does not collect info about files in app specific folders.

Hence no info from getExternalFilesdir().

Gallery apps rely on the MediaStore.

On Android below Q you can use getExternalStorageDirectory() and such.

Or Environment.getExternalPublicDirectory(Environment.DIRECTORY_PICTURES).

Picture is not showing in Gallery App in Android

The system does not scan the disk content all the time, it would kill the performances.

When you add a picture that the Gallery needs to pick-up, use

Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
intent.setData(Uri.fromFile(file));
sendBroadcast(intent);

This will allow the mediaScanner to have a look at the file immediately.

Note : if the file is incorrect for some reason, it will not have any effect.

How does appear saved SD card images in Android's Gallery?

Your problem lies here:

context.getActivity()
                .sendBroadcast(
                        new Intent(
                                Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,
                                Uri.parse("file://"
                                        + Environment
                                                .getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES))));

You are asking Android to re-index all of the files in Environment.DIRECTORY_PICTURES.

Asking to scan a whole directory tree is wasteful. In your case, it it even more wasteful, since you are not writing your file to that directory. Instead, you are writing that file to:

root = new File(Environment.getExternalStorageDirectory()
                    + File.separator + "folder_name" + File.separator);
root.mkdirs();
File sdImageMainDirectory = new File(root, "myPicName.jpg");

Hence, your scan will not pick up this file, which you are writing to some random spot on external storage.

You need to decide the proper place to store your file, then index that one file.

Stop images on sd card from showing up in gallery?

You can hide individual files from the gallery with a . prefix. For example .myimage.png

I'm not sure what version dependencies the above has and it doesn`t work with some third-party picture tools like the Gallery.

You should add a file named .nomedia into the directory where your images are. You may need to eject and re-insert the SD card before the images disappear from gallery (or otherwise trigger the media scanner) after creating this file on a phone that the Gallery has already picked up the files in the Gallery.

I think the .nomedia option is the best solution, although again, third party tools may not respect the .nomedia flag.

Download image, save to store, but image gallery cant see that image

You are saving your image to your internal app storage, you need to make it available to the gallery (external storage of your app) in order to be available outside your app.

Try this method:

private void galleryAddPic() {
    Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
    //change mCurrentPhotoPath for your imagepath
    File f = new File(mCurrentPhotoPath);
    Uri contentUri = Uri.fromFile(f);
    mediaScanIntent.setData(contentUri);
    this.sendBroadcast(mediaScanIntent);
}
