Android :: Thumbnail Reference To Actual Image

Jan 25, 2010

how will you know that this thumbnail points to which actual image in the SD card. I have a problem with MediaStore.Images.Thumbnails displaying blank previews. Though I followed mihai fonoage part 2 on how to load it properly by using scaling. Still, I got duplicate images. So instead of using MediaStore.Images.Thumbnails I used MediaStore.Images.Media instead but it loads the actual image but oading is too slow even if bitmap is scaled. That's why I was wondering if there's a way to know which actual image is the thumbnail pointing or is there a way to know the exact location of the thumbnail for this actual image (The other way around).

Android :: Populate Downloaded Image And Show In Thumbnail View?

Aug 20, 2010

I am developing an app in android, which basically visits a given url and downloads an image. Now i want to populate this downloaded image and show it in thumbnail view. I have tried out displaying the same from SD Card, but when i am doing the same for downloaded files, it doesn't seems to work.

public View getView(int position,View convertView,ViewGroup parent)
ImageView i = new ImageView(mContext.getApplicationContext());
if (convertView == null)
//int id = imagecursor.getInt(image_column_index);
//i.setImageURI(Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, ""+ id));
i.setLayoutParams(new GridView.LayoutParams(100, 100));
i = (ImageView) convertView;
return i;

Android :: Create Gray Box 70x70px And Put Thumbnail In It To Align Image With Box

Jan 12, 2010

I've got thumbnails which larger side is 70px (e.g 70x40 or 52x70).

I need to create a gray box 70x70px and put the thumbnail in it, so that image is aligned with the box at top vertically and center horizontally.

How to do that?

I've tried with an ImageView 70x70px, gray background, but image is not positioned as it should (it's in vertical and horizontal center, instead of vertical top and horizontal center).

I've also tried wrapping it with LinearLayout 70x70px, gray background and then positioning it, but then i get 1 or 2px line between LinearLayout and ImageView. I tried to set padding and margins to 0, but the gray line stays on...

Android :: How To Get Thumbnail Picture?

May 3, 2010

i'm trying to fetch a thumbnail with picture URI using these code below:

long id = ContentUris.parseId(selectedImageURI); String[] projection = { MediaStore.Images.Thumbnails.DATA }; Cursor c = Images.Thumbnails.queryMiniThumbnail(getContentResolver(), id, Images.Thumbnails.MINI_KIND, projection);

unfortunately, it's always return me the null cursor. finally, i found HTC hero never generate picture thumbnail under "sdcardDCIM.thumbnails", but only create a picture under this folder: "sdcardDCIM100MEDIA", which means i can only get the full size picture. What's am i supposed to do? create a thumbnail by myself?

Android :: Can't Get Video Thumbnail In 2.0+

Jul 18, 2010

I tried to create a video thumbnail as described here. I also read the reference here. In my app I first let the user choose a video with: startActivityForResult(new Intent(Intent.ACTION_GET_CONTENT).setType("video/*"), ACTIVITY_PICKVIDEO);

Then I determine the video ID with: fileID = Integer.parseInt(contentUri.getLastPathSegment());
So, the video content://media/external/video/media/5 would have the ID 5...............

Android :: Produce Thumbnail From Pdf

Oct 19, 2010

I am managing a bunch of PDF files in an android application maintaining a list of records in a SQLite database as well as storing the pdf files on the external storage. Now I would like to present a thumbnail of the first page of the pdf in my list view as part of each cell representing a pdf. I am aware of libraries like iText, fop.. on the JavaSE side that can render a PDF but I would rather not delve into embedding a large library like that. On a similar approach I would also rather not embed a native PDF viewer like droidreader, apv or vudroid.

Otherwise I could of course also get it rendered on a server via some webservice but that is a lot of headache as well. I am already using intents to get the pdf's displayed for the user so I was thinking it would be great if I could get a thumbnail via a intent call as a result somehow. However I found nothing on the web (e.g. on openintents) that indicates something like that exists. So I am a bit at a loss on what to do? What do you think is the best approach to get these thumbnails into my app? Are there any public intents available? Or did I just totally miss something and the SDK provides features for that already (it should imho but currently does not)?

Android : Draw Over Thumbnail In Bottom Right Corner?

Sep 3, 2010

I have a video thumbnail and when you click on it, the video starts playing in the YouTube player. This works great, but It's not so clear that you have to click on the thumbnail to play, so I have a play button image that I want to draw over the thumbnail in the bottom right corner. How would I go about this? I currently have the thumbnail in a Drawable object and the play button in my drawable resource directory. I tried stuff with bitmaps and canvas but it's quite hard and I don't know if this is the way to go.

HTC Desire :: Merged Pictures In Thumbnail Gallery

Oct 30, 2010

For a while now the thumbnail gallery has sometimes merged pictures - so on the thumbnail it's actually a combination of more than 1 picture. This hasn't really bothered me until recently because the more pictures I take the worse it's getting, so much so that I can't always tell which picture I'm going to be looking at until I actually select it. In every case the picture views correctly on the screen when I view them one at a time, it's just a problem with the thumbnails. I've attempted to clear the gallery cache which made it appear slightly better but not by much. I've checked the DCIM / .thumbnails folder but there's just loads of files in there saying file and RAW file and to be honest I don't know what it's all about. I've trawled the net and checked the forums but cannot seem to see a solution - does anyone know what I can do in order to solve this?

General :: Memory Card Keeps Filling Up Because Of Thumbnail

Jul 27, 2013

I have an HTC one s, had it for a few months and just today it started to eat up all the memory on the "external card".
It is located in DCIM .thumbnails.

I know there is a fix of changing the folder to read only and sorts.(changing the file to read only works for a few moments then a new file generates with a new number.

But I do not just want to do a fix, I would like to know how I can trace what is causing it and fix it. The thumbnail file keeps increasing in size when I erase more files, right now it is at 1.2gb.

So my question, What is causing the thumbnail to be getting to 1.2gb, a larger size then my photos stored.

Sprint HTC Hero :: Picture Message With No Thumbnail And Options

Nov 19, 2009

So today I got a message from a friend and in the message log it just tells me who it's from, the file size and when it expires. I have an option to download it but it fails every time. I doesn't give me any details that I know of it just says it was unsuccessful. The weird thing is that yesterday I got a pic from the same person and it worked fine, thumbnail and everything. What can I do to get this picture? Or make it work correctly in the future? They say they sent it the same way as the day before.

HTC Desire :: Phone Created A Thumbnail Of Video In Photo Album

When in photo albums, instead of a thumbnail of the video in question, the phone created a thumbnail of a video I have recorded previously and then deleted. Does anyone know how to make the phone recreate all thumbnails for the media files? I am leaning towards deleting all the files in /sdcard/DCIM/.thumbnails/ but not sure this is the way to do it?

General :: AT&T Galaxy SII Skyrocket - Thumbnail Images Not Showing In Gallery

Aug 28, 2012

I'm an iPhone user. Upgraded from a AT&T Samsung Fascinate to a AT&T Galaxy SII Skyrocket.

When we put her SD card from the Fasc into the Sky, all her pictures didn't transfer over, I guess only the main "Camera" album. I used the Astro app and see that the additional images that aren't showing up must be in a subfolder called ".thumbnails", since it's full of image files.

I downloaded Rescan Media and ran that but it didn't work.

Android :: App To Determine Actual Phone Specs?

Dec 9, 2009

I tried out this app: Fpt System Manager v1.1 Application for Android | Tools

And in the RAM area it currently shows me as having 83MB of RAM available out of 192.5MB of RAM. Obviously because of running apps.

What I'd like to know is how much _total_ RAM is _actually_ in my phone. The model I have is supposed to have 288MB of RAM (Rogers HTC Magic).

Is there an app, or is there some other way, to determine the actual specs of your phone, ie. actual total RAM installed?
