Get image from request thumbnails on Android

I have this code (found on this site somewhere):

    public static List<MyImages> getImages(Activity context) {
    List<MyImages> lst = new ArrayList<MyImages>();
    Cursor cursor = getCameraThumbImages(context);
    if (cursor != null) {
        int columnIndex = cursor
                .getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID);
        int columnIndexPath = cursor
                .getColumnIndexOrThrow(MediaStore.Images.Thumbnails.DATA);
        int columnIndexImagePath = cursor
                .getColumnIndexOrThrow(MediaStore.Images.Thumbnails.IMAGE_ID);
        int count = cursor.getCount();
        for (int i = 0; i < count; i++) {
            cursor.moveToPosition(i);

            int imageID = cursor.getInt(columnIndex);
            String path = cursor.getString(columnIndexPath);
            Uri imgThmbPath = Uri.withAppendedPath(
                    MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, ""
                            + imageID);
            String hope = cursor.getString(columnIndexImagePath);
            MyImages p2p = new MyImages(path, "" + imageID);
            lst.add(p2p);
        }
    }

    return lst;
}

      

This code allows me to access thumbnails of images on my phone. The problem is I can't see how to get the original image path from this.

Question: Given the thumbnail (or cursor), how do I get the original path of the image?

In the thumbnail, you have a MediaStore.Images.Thumbnails.IMAGE_ID field, you can get the image of the image associated with it. Then make a request to MediaStore.Images.Media and get the path to your photo from the MediaStore.Images.Media.DATA field.

EDIT



// First request thumbnails what you want
String[] projection = new String[] {MediaStore.Images.Thumbnails._ID, MediaStore.Images.Thumbnails.IMAGE_ID};
Cursor thumbnails = contentResolver.query(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, projection, null, null, null);

// Then walk thru result and obtain imageId from records
for (thumbnails.moveToFirst(); !thumbnails.isAfterLast(); thumbnails.moveToNext()) {
    String imageId = thumbnails.getString(thumbnails.getColumnIndex(Thumbnails.IMAGE_ID));

    // Request image related to this thumbnail 
    String[] filePathColumn = { MediaStore.Images.Media.DATA };

    Cursor images = contentResolver.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, filePathColumn, MediaStore.Images.Media._ID + "=?", new String[] {imageId}, null);

    if (cursor != null && cursor.moveToFirst()) {
        // Your file-path will be here
        String filePath = cursor.getString(cursor.getColumnIndex(filePathColumn[0]));
    }

}

//Of course you need to restrict queries using selection and selection args params and get only rows that you really need
