Download Image and store it in Gallery app in android

Question

I want to save Image file in Gallery so that Image can be viewed from the Gallery application.

But what I want is to create a separate dir, as like we have for whatsapp Images etc apps in our gallery application.

So far I have written this code to download an image

public void createDir(){
  File dir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), DIR_NAME);
    Log.d(LOG_TAG, "dir pictr :" + dir.toString());
    if (!dir.exists()) {
        dir.mkdir();
        Log.d(LOG_TAG, "dir not exists and created first time");
    } else {
        Log.d(LOG_TAG, "dir exists");
    }
}

Above code created directory inside gallery dir

Uri imageLink = Uri.parse(downloadUrlOfImage);  // this is download link like www.com/abc.jpg

CreateDir();
DownloadManager.Request request = new DownloadManager.Request(imageLink);

File dir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), DIR_NAME);
String absPath = dir.getAbsoultePath();
request.setDestinationUri(Uri.parse(absPath + "image.jpg"));
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);

DownloadManager dm = (DownloadManager) getContext().getSystemService(Context.DOWNLOAD_SERVICE);
dm.enqueue(request);

But this gives me error as java.lang.IllegalArgumentException: Not a file URI: /storage/sdcard0/Pictures/FreeWee/1458148582.jpg

Basically what I want is to save Image and that image must be shown in Gallery Application under Some directory I named.

If not understood please ask, so that I can improve my question. How do I proceed further ?

Answer 1

As @RoyFalk pointed out you got 2 issues in your code.

So you can go with this code snippet

String filename = "filename.jpg";
String downloadUrlOfImage = "YOUR_LINK_THAT_POINTS_IMG_ON_WEBSITE";
    File direct =
            new File(Environment
                    .getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)
                    .getAbsolutePath() + "/" + DIR_NAME + "/");


    if (!direct.exists()) {
        direct.mkdir();
        Log.d(LOG_TAG, "dir created for first time");
    }

    DownloadManager dm = (DownloadManager) getContext().getSystemService(Context.DOWNLOAD_SERVICE);
    Uri downloadUri = Uri.parse(downloadUrlOfImage);
    DownloadManager.Request request = new DownloadManager.Request(downloadUri);
    request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE)
            .setAllowedOverRoaming(false)
            .setTitle(filename)
            .setMimeType("image/jpeg")
            .setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED)
            .setDestinationInExternalPublicDir(Environment.DIRECTORY_PICTURES,
                    File.separator + DIR_NAME + File.separator + filename);

    dm.enqueue(request);

And you will see Image inside the gallery application under your DIR_NAME. Hope this will help you.
