I am creating an Application which will run on all Android Devices. I want to create xhdpi Graphics for My App. My App is full screen. I am confused in Creating graphics. can any one tell me the best sizes of my background image in pixels.
For Example:
Suggest me the best sizes which will appear on all devices good. Because my graphics are the core of my app.
I want that every device get the best image which it want. Android will be not involved in compressing or expanding of image.
Android Devices Matrices
ldpi mdpi hdpi xhdpi xxhdpi xxxhdpi
Launcher And Home 36*36 48*48 72*72 96*96 144*144 192*192
Toolbar And Tab 24*24 32*32 48*48 64*64 96*96 128*128
Notification 18*18 24*24 36*36 48*48 72*72 96*96
Background 240*320 320*480 480*800 768*1280 1080 *1920 1440*2560
(For good approach minus Toolbar Size From total height of Background Screen and then Design Graphics of Screens )

My understanding is that if you use a View
object (as supposed to eg. android:windowBackground
) Android will automatically scale your image to the correct size. The problem is that too much scaling can result in artifacts (both during up and down scaling) and blurring. Due to various resolutions and aspects ratios on the market, it's impossible to create "perfect" fits for every screen, but you can do your best to make sure only a little bit of scaling has to be done, and thus mitigate the unwanted side effects. So what I would do is:
getDisplayMetrics().density
returns 4 (xxxhdpi), so perhaps this info is outdated.Then look at the new phone models on the market, and find the representative ones. Assumming the new google pixel is a good representation of an android phone: It has a 1080 x 1920 resolution at 441 dpi, and a screen size of 4.4 x 2.5 inches. Then from the the android developer docs:
- ldpi (low) ~120dpi
- mdpi (medium) ~160dpi
- hdpi (high) ~240dpi
- xhdpi (extra-high) ~320dpi
- xxhdpi (extra-extra-high) ~480dpi
- xxxhdpi (extra-extra-extra-high) ~640dpi
This corresponds to an xxhdpi
screen. From here I could scale these 1080 x 1920 down by the (3:4:6:8:12) ratios above.

The following are the best dimensions for the app to run in all devices. For understanding multiple supporting screens you have to read http://developer.android.com/guide/practices/screens_support.html
xxxhdpi: 1280x1920 px
xxhdpi: 960x1600 px
xhdpi: 640x960 px
hdpi: 480x800 px
mdpi: 320x480 px
ldpi: 240x320 px
I looked around the internet for correct dimensions for these densities for square images, but couldn't find anything reliable.
If it's any consolation, referring to Veerababu Medisetti's answer I used these dimensions for SQUARES :)
xxxhdpi: 1280x1280 px
xxhdpi: 960x960 px
xhdpi: 640x640 px
hdpi: 480x480 px
mdpi: 320x320 px
ldpi: 240x240 px
GIMP tool is exactly what you need to create the images for different pixel resolution devices.
Follow these steps:
Use below pixel dimension that you need:
xxxhdpi: 1280x1920 px
xxhdpi: 960x1600 px
xhdpi: 640x960 px
hdpi: 480x800 px
mdpi: 320x480 px
ldpi: 240x320 px
Then "Export" the image from "File" menu.
