Android :: Size Of Background Images To Support All Android Screens
Jun 25, 2010
I'm writing an application and I want one of my activities to have a background. I've read the android docs about supporting multiple resolutions etc. but my designer is asking me what size the wallpapers should be and I do not want a lot of images for low, normal, high dpi in all the screen sizes.
What would be the most space efficient way to get a nice screen filling graphic background on all those screens? Android is great and all, but I do not want to end up with a huge application since I need all sizes of images for everything.

I want to develop application that should support all version (latest and old) and it should adjust screen resolution (large,medium). I read document. There I found legacy application if I develop application in 1.6 there I am giving:
<uses-sdk android:minSdkVersion="3" android:targetSdkVersion="4"/>
Is it good way to develop application and is it support 1.5 and 1.5+. Users able to find my application there market.

So I Customized my Droid Eris with all my Widgets and such and made it my own. I turned it off, and turned it back on and EVERYTHING (including the default widgets and such) were all gone. The screen was completely empty with just my wallpaper in the background. All 7 of the screens are completely blank. I'm going to redo everything but if I such off my phone will this happen again? Can someone please tell me what went wrong? Thanks!

I have been developing on a ADP2 (Google Ion) with a "standard" screen size (with a resolution of 320x480)... Our designer made some pretty neat Images with which to create the GUI, and when placing everything within the layout XML files it looks pretty good... That is, on the Eclipse renderer, the one who shows you how it will look like on the device... Thus not the emulator itself... Unfortunately when run on the real device the supercrisp and beatifull images become blurry and unsharp... I actually do'nt see why this should happen ? Everything has been designed whilst keeping the target devices resolution into account... Is this because most probably the dpi of the screen on which the Images were (big 24 inch screen) is different that the devices? And if so how can this be corrected (maybe within the designers application as well, I think he uses Photoshop).

I have an array of all the URIs of the images which I am showing in a List. Now I want to run a thread in background which gets this images from web and store them on the SD card. So when I click a particular element in the list instead of fetching from web it should fetch from the SD card in the new activity.

I have an image that I want to place on the background on my activity. For the G1 I would use a background of 320x480 but with the nexus 1 the resolution is almost double that. Should I just place the large image and make the smaller phones size down? I am trying to keep the size of my package down as much as possible.

I guess this question has been asked before, but I can't seem to find a proper answer/solution. Have a note-taking app, which allows to take pictures. For that I start an intent, that starts up the built-in camera-app. So far so good. But when I show that image in my app, it's in a much smaller format The funny/weird thing is, that the camera-app did take a full-resolution picture! But for some reason I can't get the full version to show in my app? So, when I use the standard Android Gallery app, and go to that picture, it is very obvious that it's full size (I can zoom in and see details I really can't see when I zoom in, in my own app). Also, the dimensions are really those of the original picture, taken with the 5MP camera. In my app, they are very small. My phone has Android 2.2, but the same happens on my emulator (Android 2.1). How should I retrieve the pictures in my app? Tried a couple of ways, but none works :( Don't need a complete example (allthough that's very welcome), just a few clues are enough to search for myself.

I am trying to develop an app for which I want multiple screen support. I have read the Android article on Best practices for Multiple Screen Support. As per the article we have to follow 3 important things:
1. Mention support for different screen sizes (large, medium and small) and any density in AndroidManifest.xml.
2. Place images of 3 dpi's (120, 160, 240) in 3 folders res/ldpi, res/ mdpi and res/hdpi.
3. In layout's the dimension should be mentioned in "dip" units. Then Android will take care of the scaling on its own.
I have implemented all these points in my project. The images are picked up correctly from the appropriate folders. But the arrangements of the controls in not same. e.g. I ran the app on three emulators 1. Resolution 240*320 dpi 120. 2. Resolution 240*320 dpi 160. 3. Resolution 240*320 dpi 240. (All the emulator have same resolution but different density). The problem is the position of the controls is not same on all the three emulator. As per my understanding if the android:layout_marginLeft and android:layout_marginTop are mentioned in "dip" then this problem should not occur. As the density of the emulator increases the controls get placed more towards the right. Is it necessary that I provide layouts for all combinations of dimensions and density i.e. in layout-small, layout-large, layout- medium, layout-long,layout-notlong?

I am a bit confused on creating an image which will be acting as a background for my activities. So, in short, my aim is that my application should be able to fit the different screen sizes. Therefore, what size in pixel should my three images be to be able to fill the screen of the device in ldpi, mdpi and hdpi?

I'd like to be able to use an image as my background in a relative layout, without it stretching. I don't want to just enter the images details into an XML file, as I want to use different images, with different sizes. I've tried the following, but it just stretches the images (I know the left, top, right and bottom variables have the wrong values, but I've just entered something into them, as a test to see if it makes any difference to the output, but it does not. If it did, I'd calculate the correct values programmaticly : -
RelativeLayout explosionlayout = (RelativeLayout) findViewById (R.id.explosionlayout);
imageAnim = (ImageView) findViewById(R.id.explosion);
Drawable d;
d = this.getResources().getDrawable(R.drawable.bomb);
int left = 10; int top = 10; int right = 20; int bottom = 20;
d.setBounds(left, top, right, bottom);
explosionlayout.setBackgroundDrawable(d);

IŽm working on the UI of my first app and IŽd like it to work on as many different devices as possible. IŽve read on the net about AndroidŽs rule not to resize bitmaps on views (background, buttons, etc), is it true? Does android rescale skinned views sizes the same way it resizes the default ones? Also, if not, how can I handle the more than 5 display sizes using a background image and skinned buttons and scrollers (horizontal bar)?

I have my photo settings reset to factory settings, I did this because after I transfer my images to my computer, they are only full thumbnail size. I have selected on the camera the 16M setting, so as I understand that should be pretty big right? (bare with me, I am not by any means a photog) so I am assuming some where in the camera I must have changed a setting that changes the maximum image size for transfer? I am so lost and confused, I just want nice pics of my kids.

I have a bunch of png images that I imported to my phone from my PC. I dumped them straight in my DCIM folder.
On the PC, these images have transparent backgrounds, however, when I view them using androids gallery app, the background is black. Similarly, when using these images as stickers for my text messaging app (Naver Line), the backgrounds will also show as black.odate.

I just bought Beautiful Widgets 3.0 off of App market and have been trying to add the Beautiful Home Weather widget on my home screen. However, no matter which weather skin I choose, the weather images are running off of the background on the bottom as if the background image is not long enough. I tried a few skins, but they all look the same. Is there an option I need to toggle or something?

I'm basically using the same method of loading bitmaps in OpenGL that the SpriteMethodTest example uses and have been unable to get rid of an annoying outline that appears around all of my images.
For example, If I were to load an image of a white circle on a white background, I would expect to see nothing. Instead, I would see my circle because its edge would be gray. In SpriteMethodTest, I replaced the background image with white and was able to see that the edges of the android images flying around also don't seem to be rendered correctly.
Does anyone know how to load images in OpenGL without having a thin outline appear around the images?

I had a little time with the captivate today and noticed it has 4(i think) horizontal scrolling screens for apps. What happens when you fill those? Does it automatically add another one or what?

I'm working to convert some background images to nine patch so they scale better on different phones.
The problem is that if I have the following resource structure: drawable-hdpi/background.png drawable-hdpi/button.png drawable-mdpi/background.png drawable-mdpi/button.png drawable-ldpi/background.png drawable-ldpi/button.png and then I drop a new drawable-hdpi/background.9.png file into the mix, it breaks button.png during the pre-compile. The error is "No resource found that matches the given name (at 'background' with value '@drawable/button').Simply removing that one nine patch file fixes the build. Should I be able to have some nine patch images and some normal ones, or to have nine patch only in hdpi but not mdpi or ldpi? This is Eclipse 3.5.1 with the latest ADT.

So I'm loading images from a web service, but the size of the images are sometimes smaller or bigger than other images and the visualization looks silly when I put them in a ListView in android. I'd like to fix the size of my ImageView so that it only shows a portion of the image if it's larger than a preset amount. I've tried everything I can think of setting the setMaxWidth/setMaxHeight, setting the scale type to centerCrop, using ClipableDrawable wrapping my BitmapDrawable, setting using Drawable.setBounds(). I've tried setting in the XML and programmatically, but neither worked. I'm very surprised setting max width/height didn't do anything. Below is the XML I'm using ImageView definition in my layout file

I am currently developing a dictionary application with voice database. I would like to know about the current Android limitation on the file size. I am using a self-provided sqlite database ( > 50mb ) . I tested that once the built .apk size exceeds ~30mb the app will not be installed onto the simulator (INSTALL_FAILED_ INSUFFICIENT _STORAGE). Could anyone confirm me that if up until now there is no way to embed such large size files in a single apk ( Aimed to sell at Google Market without requiring user to download datafile afterwards). Also, is there a limitation of 1,048,576 bytes for a single file in the assets folder ?

Can somebody explain to me what makes up the installed application size? I have an apk that is about 8 MB, and often when I install I get the INSUFFICIENT_STORAGE error. I have around 25-30 MB free space on the phone. I'm doing debugging so I have to upload lots of new versions. If I uninstall the previous version then I can install the new version. The application manager claims that the app is taking up 22 MB. So back to the original question, how come the app is taking up 22 MB when it really only is 8 MB?

I would like to know why the size of my shared library .so is bigger than my .apk file generated with Eclipse? Approximatly the so size is twice the apk one. What is strange is after having installed it in the device (2.1 firmware) I checked the size of the apk when I uninstalled it from the device and surprisingly the apk size indicated is bigger even than the .so one. Is there any explaination of that?
