I know this has to be trivial but I just don't find the right resource, I guess.
So all I want to do is retrieving a thumbnail for a video. All I have is the absolute path to the file on the sdcard as a String. So please point me into the right direction.

I need to get the absolute path of the file associated with a specific android.net.Uri instance. I know how to get the URI instance based on the file instance (with Uri.fromFile(file)) and i need the inverse action.

I set the video by using the setVideoPath('/path/filename') method, but can't seem to figure out how to get the path on an existing object?

I am using ACTION_IMAGE_CAPTURE for capturing image using intent as follwo..

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...............
Hi,
Is there any api on android which generates a Thumbnail image from an inputstream which is a video file?
Thank you.
I just recorded a video clip which had a strange effect. 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?

Is there a way to read the points created when drawing a path? It seems silly to me that a path cannot be readable.Or is it just better to manually write the current finger position to an array?

I guess I need to get current time and it should have nothing to do with user handle or location actually, I'm focusing '30minutes from now' rather than current time. It also should work even in case of power off and on. Can I use alarm manager for this?
View 12 Replies View RelatedI'm trying to get the absolute screen pixel coordinates of the top left corner of a view. However, all methods I can find such as getLeft() and getRight() don't work as they all seem to be relative to the parent of the view, thus giving me 0. What is the proper way to do this?
If it helps, this is for a 'put the picture back in order' game. I want the user to be able to draw a box to select multiple pieces. My assumption is that the easiest way to do that is to getRawX() and getRawY() from the MotionEvent and then compare those values against the top left corner of the layout holding the pieces. Knowing the size of the pieces, I can then determine how many pieces have been selected. I realise I can use getX() and getY() on the MotionEvent, but as that returns a relative position that makes determining which pieces were selected more difficult. (Not impossible, I know, but it seems unnecessarily complicated).
View.getLeft() and View.getTop() give the position of the view relative to the parent.
Is there a way to get the absolute screen position of that view?
Either a way to translate those coordinates into screen coordinates to make a call to get the position in screen coordinates.
I am trying to go widget-free, using Zeam launcher instead of LauncherPro which seems to randomly have issues for me, I'm just wondering what tips you all may have for getting the best performance possible from your phone. I'm on a Captivate. I care more about in-app performance and stability over bells and whistles. What do you suggest?

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?
I have retrieved some cover art for an album (I have the id and a Bitmap) and now I want to set it into the MediaStore. I tried a bunch of stuff:

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)?

View 1 Replies View RelatedIs it possible to set the absolute position of a view in android? (I know that there is an AbsoluteLayout, but it's deprecated...)
Lets say I have a screen 240x320px, and I want to put an ImageView which is 20x20px with its center at the position (100,100).
What do I have to do?
If you use an AbsoluteLayout (I know that it is deprecated, but it was the only way to solve my problem ) you can give the childViews the tag "android:layout_x" and "android:layout_y" to set their absolute position within the AbsoluteLayout.
However I dont want to set these informationen in the xml, because I only know them at runtime. So how can I set these parameters at runtime programmatically? I dont see any method on the View like view.setLayoutX(int x) or something.
Here is my XML, which works fine, when I set the layout_x and layout_y values. code...

Can anyone tell me that why i am not getting full image on G1 mobile screen?
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).

How to obtain ID of an image by the ID of the thumbnail?
And what about going from original image to thumbnail ID? Is that possible? I saw MINI_THUMB_MAGIC but it seems there is an issue with it.
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.
View 2 Replies View RelatedI have a custom ViewGroup. The idea is to be able to place controls at absolute positions and then have the ViewGroup scale those controls based on the difference in the screen dimensions with respect to the original design dimensions. I am using the code below. In response to the 'onMeasure' message, I am storing the width and height of the view. Then on the 'onLayout' message I am computing new dimensions for the child controls and adjusting their sizes proportionally. This all works to some degree. However for certain controls (e.g. button controls), the control resizes, but the text inside does not remain centered within the control. I am thinking that there is some other call I need to make to update the child controls after I change their size.
