Android :: Possible To Obtain ID Of An Image By Id Of Thumbnails?
Jun 25, 2010
I'm developing an image editor for android. In the main activity, I get to show all images by viewing the thumbnails to make the process faster. The problem it's that I need to process the image later and I would get the normal image ID (with the original size, which I think is in MediaStore.Images.Media). I can't get the form of the query. The code that I have is the following but I can't obtain the real image ID (in the IDImage variable) code...

I am working on a little side project (program for Android platform)and I don't exactly have a problem, but I don't really know where to start. The project I am working on has to do with getting the info and manipulating a pixel's RGB values inside an image. I know this is a very basic program (not going to disclose all the information about the project), but I am a beginning android programmer.

I created a video recording application with library dialog. The library dialog displays the list of recorded videos where each item consists of icon, video title, tags and location information the following way:
Does anyone know whether it is possible to replace icons with video thumbnails (single frame preview)?

My application loads 12 100x100 thumbnail images from the web using the code below. I then display the thumbnails in a GridView using an ImageAdapter derived from BaseAdapter.I'm running into memory issues because each of the thumbnails is held in memory as a Bitmap. This seems like a fairly straightforward application (display a gallery of thumbnails from the web), can some give me advice on how to reduce my memory needs? Maybe there's a better way to display web images in a GridView that doesn't involve downloading and storing each one as a Bitmap?

AFAIK accessing thumbnails for images via MediaStore.Images.Thumbnails would generate thumbnails at first attempt, and that's what i need to perform against specific location on sd card.
The question is how to make valid URI to content under specific folder?
All answers i can find use just MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI as uri to make managedQuery. And result of it is Cursor that points to all sdcard images, while none examples can be found on how to access only specific folder.

Is that normal that Images indexed in the MediaStore do not have thumbnails generated until the Gallery app is launched and the user actively navigates to the bucket where the image is stored ?
I think it's quite odd as I thought thulbnails generation was part of media indexing.

I am working with the sample Home application project on http://developer.android.com/resources/samples/Home/index.html
I've added another value to the THUMBS_IDS and IMAGE_IDS Integer arrays in the Wallpaper class for a total of four wallpaper options.
When I run the application with Device API version 7, Skin: HVGA, hw.lcd.density: 160, in portrait layout, the fourth wallpaper option is not shown.
I need to use the directional keys in the emulator to see the 4th wallpaper option, because the first option is centered.
I have modified only the wallpaper.xml file with a variety of android:layout_* options with no success at this point.
How do I show all four of my wallpaper options?

I have several images present in different folders in my sdcard. I would like to display a list of thumbnails. So what I have done is while rendering any row in the list I read the file in an input stream, get the byte array, decode it to obtain a bitmap and set it in an imageview.
So far so good. But when I scroll the list, the list scrolls in jerks. I believe this is because decoding a bitmap from byte array takes some time. What I would like to know is that, is there any optimization which I can do to improve the performance, or better still is there any better method to achieve what I want ?

I use http://stackoverflow.com/questions/541966/android-how-do-i-do-a-lazy-load-of-images-in-listview/3068012#3068012 to load images in a ListView and a GridView. It works but the images are loaded form bpttom to top. How to fix that?
Bonus Question: Can I use a loading animation in a image view while the real image is loaded? Right now it's just a default image.

I'm trying to figure out why some of the thumbnails of attached pictures don't automatically show up when I open the message. It seems like when I open an older message that has 5 or more pictures in it, it will not show the thumbnails, so I have to go through and click preview to see them. And then it will only keep the thumbnails visible for the first 5 that I previewed. And sometimes it won't show any of of the thumbnails when I open a message, even if its only 1 or 2 pictures.

How change Bookmarks to list view, not thumbnails?Had it done before, but, somehow, phone lost the setting. I want to see my bookmarks as a list, so that I can see more of them at a time, rather than the too big thumbnail view.

Is there ANY way to keep the bookmarks, but clear the thumbnail picture information? I've tried clearing the history in the browser, but that's not doing the trick.

I've recently had a problem where ONE of my photo albums (not all) has corrupt square preview thumbnails. They look like static images off a TV with no antenna signal, and they ONLY look this way in grid mode. If I switch to filmstrip mode, they are fine. And all of the photos themselves are all fine. It's just the previews for this one album in grid mode. I tried just clearing the photo apps' cache - but no better. how to rebuild them?

My wife and I both bought new Android phones. I've set each of us up with a gmail account, and I was able to successfully import my contacts from iTunes (I had an iPod Touch). I've spent quite a bit of time in Gmail editing the contacts and adding photos, phone numbers, etc, and would like my wife to share these as well, as a starting point. So what I did was export the contacts to my desktop as a .csv file, then log into *her* account, and import the.csv file. That works great, except I don't have any of the thumbnail photos (which makes sense, 'cause there's nothing in the .csv file about photos). Is there another way to share my contacts with photos, short of going through the whole process of editing each contact from her account and adding a photo?

I really like BS Player and use it constantly on my Galaxy Tab 10.1.
I find it has a fantastic LAN streaming capability and great interface. However, it auto selects the thumbnails.
This isn't necessarily a problem for me bc I use it set to 'file list'.
However, my 5 yr old can't read yet, so I set it to Thumbnails.
Unfortunately, the auto gen thumbnail feature selects some random frame 99% of the time, and the image will have no bearing on the movie whatsoever.
Is there another video player that allows you to select your own thumbnail from a screenshot or picture file?

I noticed that I suddenly lost thumbnails of images that showed the previous day in the stock photo apps and also the Gallery app. They show up and open using Astro, but appear to no longer be seen by the indexes of photo and Gallery (but open fine using those apps via Astro). I tried B&B as well and same thing. They all must use the same index source.
I like the stock photo app the best, since it shows pics and movies for both internal and external memory. Never had this problem before. I tried SDrescan, but it just says "scanning" and even after two hours, never stops scanning. I have tried clearing cache, etc., but still they do not show, even when I created a new directory to put them in.

So I know the method of hiding a file or folder by placing a period in the beginning of the title then SETTINGS > *Uncheck* SHOW HIDDEN FILES
Okay, to make everything clear...... from the home page I go to my Apps......click FILES, then there are the following items: ALL FILES, IMAGES, VIDEOS, MUSIC, DOCUMENTS.
When I click IMAGES....I get to my CAMERA, a generic PHOTO album, and some downloads from FACEBOOK. There are also two hidden files called .THUMBNAIL and .THUMBNAILS2 (I may have named one of them I'm not sure).
What are these files for? They contain literally thousands of previous and current pictures I had stored in my phone including deleted pics. They are lower resolution than normal too. I want to delete the ".thumbnail" folders but I don't know what will happen. They're annoying me and include a lot of deleted stuff.

I would like to write an app on Android to upload my GPS location to an external website once every 5 minutes. This needs to have as minimal an impact on battery life as possible, but it also needs to work without any user interaction. (Background: I'm competing in an Ironman triathlon which will take me about 14 hours to complete, and want to broadcast my location in near-real-time but without having to worry about fiddling with my phone.) So my initial thought is to write a Service which uses LocationManager.requestLocationUpdates() with a minTime of 5 minutes, but will this actually wake the device up every 5 minutes for my service to do its job?
It sounds like I would also need to use AlarmManager.setInexactRepeating() to make sure my service is awake while it completes its task but how does that play with requestLocationUpdates()? Should I instead set minTime=0 on requestLocationUpdates() but then go back to sleep as soon as the next update is obtained? Any general guidance on how to design this. I'm a competent Java programmer & will be using Google Maps on the server to plot my location, but am pretty new to Android development so I'm basically looking for a high-level plan on how to architect the client app.

I'm trying to obtain an instance of ServiceState in my Activity. But how am i supposed to do this? There is no static method to obtain an instance or any method on any service that returns an ServiceState instance.
There is the TelephonyManager.listen() call. But i want to get the ServiceState instance when i want, not when android calls my listener because something changed.
The documentation of ServiceState can be found here: http://developer.android.com/reference/android/telephony/ServiceState.html

I'm trying to obtain the battery temperature, the battery voltage and the battery current. The return value of the code (see below) for voltage and batteryTemperature is always 0 while the others work. I would like to know if there's any other way of obtaining this information and how. Finally, I couldn't find anything in the API for accessing the battery current... Is there any method to know its value? Code...

I have different text packaged into my app for different locale. The Resource.getString(int resid) method automatically returns me the string for the CURRENT locale of the phone. Is there a way I can specifically obtain resources while passing in a locale? For example, there isn't such method as: Resource.getString(int resId, Locale myLocale);

In the licensing documentation the android developers mention an easy way to more or less securely identify an android device. They are using android.Settings.Secure.ANDROID_ID.
They say they query the system settings for this. But they don't explain this any further.
How do I obtain the android_id and do I need special permissions for doing so?
