Path to Android folder with all images

I'm trying to build a feature to load the latest saved image from the device into an app. Currently I'm using this path DCIM/Camera/ but it only stores camera taken images. Is there a folder that stores all images? (screenshots, images saved from the web or camera roll)

Instead of searching in in folders for the images, you can let the system take care of that for you.

Android indexes most media-data (images, music, etc) on it's own and offers Content Providers to query these databases.

For your purposes, you can use the MediaStore.Images.Media-provider.

public List<String> getImagePaths(Context context) {
    // The list of columns we're interested in:
    String[] columns = {MediaStore.Images.Media.DATA, MediaStore.Images.Media.DATE_ADDED};

    final Cursor cursor = context.getContentResolver().
            query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, // Specify the provider
                    columns, // The columns we're interested in
                    null, // A WHERE-filter query
                    null, // The arguments for the filter-query
                    MediaStore.Images.Media.DATE_ADDED + " DESC" // Order the results, newest first
            );

    List<String> result = new ArrayList<String>(cursor.getCount());

    if (cursor.moveToFirst()) {
        final int image_path_col = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        do {
            result.add(cursor.getString(image_path_col));
        } while (cursor.moveToNext());
    }
    cursor.close();

    return result;
}

The method will return a list of the image-paths of all images that are currently indexed by the MediaStore with the latest first. You'll need the android.permission.READ_EXTERNAL_STORAGE-permission for this to work!
