Android :: Setting Wallpaper Through Code
Jun 14, 2010
I was trying to make an app which also had the facility to let user select wallpaper he would like to set. I have managed this by calling the Gallery Intent. Once the user selects a specific image, the data path of the image is returned to me which then i preview to the user by setting the image onto an imageview.
The problem crops up when the image size (and/or resolution) is greater than what android expects. This results in failure of my module.
And as if this was not enough, wen the user tries to select some other wallpaper(and in my test case the "other" wallpaper was also of size >700kb) then the app crashes with the "OutOfMemoryException"...
For Gallery Intent i use:
CODE:............
For setting the wallpaper i use:
CODE:.......
So i have 2 problems to deal with:
How to crop the image before setting it as wallpaper...Cant understand y OutOfMemoryException is thrown, coz none of my image sizes exceed even 1mb... and i guess the VM budget in case Of N1 is 24Mb if m not mistaken...

I'm setting the wallpaper using any one of the available methods:
- getApplicationContext().setWallpaper(bitmap) - WallpaperManager.getInstance(context).setBitmap(bitmap)
The image I'm using is 320 * 400, but when it gets set only the center section of the image is displayed, like the image is way too big for the screen. My screen is hi-res, and this should fit into it easily.

Is there a way to set a live wallpaper, similar to WallpaperManager.setBitmap() to set a static image?

Under gallery, I've tried setting wallpaper from images stored. I'm experiencing two problems:
1) When using the green border to select the part of the image I'd like, it never stretches to the full size of the image. It maxes out at about half the size of any image.
2) Once cropped after clicking set as wallpaper, the wallpaper shows way too zoomed in and I lose at least half the image I cropped.

I am working on an Android application that is supposed to run on Android 1.5 and later devices. I am using RawContacts.CONTENT_URI enumeration for registering a ContentObserver in my application subclass. Now, RawContacts was introduced in Eclair and running this code on Android devices having runtime less than 2.0, gives java.lang.VerifyError. For older devices, I have to use Contacts.CONTENT_URI.
So to fix this, I've put something like the following in my code:
CODE:.......
I am still getting java.lang.VerifiyErrors.
How do I setup my code for different runtimes?

I just purchased a fascinate today and it's pretty solid, however I noticed that when I try to set a custom picture for the background, it won't let me select the whole picture and it zooms in ridiculously too much. Now, I've tried almost everything, but nothing seems to work. Can anyone help me?Oh, if you have the fascinate, download handscent for messaging. I had a blackberry before the fascinate and it's similar to the crunch sms for blackberry. It's convenient because it allows you to customize the length of the vibrations and led lights, but the fascinate doesn't seem to have led light capability. It also allows you to customize the bubbles a well as the colors per contact and all that. Definitely something to look into.

Is there a way to do it? I took a picture in portrait that fits the Droid X screen size perfectly and I want to use that as my wallpaper. I have scrollable wallpaper off and don't use the landscape mode for the home screen. I have that turned off as well. So really it makes no sense and its highly annoying.
I made a video to show what I was talking about because its kind of hard to explain...or some people just don't get it. Whatever if you don't understand let me know and I'll post the link up to youtube after its done uploading.

I am able to set Home Wallpaper without the picture losing quality. However, I still can't set LockScreen Wallpaper without risking quality in the picture.
Why does this happen? Why the hell can't I enjoy the 100% good quality HD wallpapers that I download? Every time I set one it instantly loses quality.

I have read about using a 'dip' scale rather than just px, this is straightforward to implement in XML. But how do I adjust values accordingly in the java code? For example:
tv.setTextSize(20)
will result in text of size 20 px right? What's the quickest way of making this 20 dip, other than adding a resource?

Annoying that when I go to select a wallpaper, the "Pictures" option pulls up every single image on my SD card (icons for apps, CD art, etc.), when all I want it to do it pull images from my "Wallpaper" folder.
Is there any way to customize what images get pulled? Can folders (like CD art) be hidden from gallery view so that they don't show up in the "Pictures" list?

I'm doing it by going to chrome>google>images>wallpaper>save image>gallery>set as. But problem is it always seems to be low quality when I do it that way. The wallpapers aren't low quality it's 1920x1200. When I open them in images it always appears small, so I think I'm actually saving that small image.

What is the best wallpaper/brightness setting for outdoors screen visibility? This morning I was running late for my lift and I missed a call from my mate asking where I was. I got my phone out and couldn't see a thing on the screen so had no idea who was ringing me. Turns out a plain black wallpaper and lowest setting brightness does not like being outdoors.

2/ how do i set a wallpaper using adb?

I'm trying to have my home-screen application register itself as the default home-screen so the user is not prompted with the IntentResolver's list of all the available home-activities.
This is my code:
CODE:.................
I have the android.permission.SET_PREFERRED_APPLICATIONS set in the manifest. After executing the code above, the logs claim things have been added like expected (same logs as when I tick off "Make default" from IntentResolver's list). However, when I proceed by clicking home, the list still shows up and the logs say:
CODE:.....................
So it seems the resolver deletes the default entry. Am I doing something wrong, or is this a security measure? What are the ideas behind this?

I'm playing with the alternative Home app that comes with the SDK.
I can set this as default for 'Home' action.
I can unset this by -->Setting->Manage Application->My Alternative Home-> "clear defaults"
Question:
How to do this "clear defaults" by code?
I've browsed the forums but cannot find an answer.

I want to set this picture as my Wallpaper. The problem is, when I select "Set As", the picture suddenly appears with a lower quality.
Here's the picture as it is, and then after I press on "Set As".
As you can see, in the second picture, the wallpaper has a lower quality. I didn't zoom in or anything, but somehow I cannot get the best quality (shown as I see it in my gallery), as soon as I try to set it as my wallpaper, the quality lowers.
