For detail, please refer to Android Developer Guide.
To summarize, you must declare each supporting screen sizes in your AndroidManifest.xml
. For example, you have to include the following:
<supports-screens android:resizeable=["true"| "false"]
android:smallScreens=["true" | "false"]
android:normalScreens=["true" | "false"]
android:largeScreens=["true" | "false"]
android:xlargeScreens=["true" | "false"]
android:anyDensity=["true" | "false"]
android:requiresSmallestWidthDp="integer"
android:compatibleWidthLimitDp="integer"
android:largestWidthLimitDp="integer"/>
To support 240*320, you must do the following:
1: In AndroidManifest.xml
, include
<supports-screens android:smallScreens="true" />
2: Create different layout-small
folder:
res/layout/layout-small/
3: Create drawable-ldpi
folder (you already did):
res/drawable-ldpi/
Try following scenario of layout. I found at http://jamil.fluidsoul.net/2011/03/06/creating-android-applications-for-multiple-screen-sizes.
Low density Small screens QVGA 240x320 (120dpi):
layout-small-ldpi (240x320)
layout-small-land-ldpi (320x240)
Low density Normal screens WVGA400 240x400 (x432) (120dpi):
layout-ldpi (240 x 400 )
layout-land-ldpi (400 x 240 )
Medium density Normal screens HVGA 320x480 (160dpi):
layout-mdpi (320 x 480 )
layout-land-mdpi (480 x 320 )
Medium density Large screens HVGA 320x480 (160dpi):
layout-large-mdpi (320 x 480 )
layout-large-land-mdpi (480 x 320)
Galaxy Tab ( 240 dpi ):
layout-large (600 x 1024)
layout-large-land (1024 x 600)
High density Normal screens WVGA800 480x800 (x854) (240 dpi):
layout-hdpi (480 x 800)
layout-land-hdpi (800 x 480)
Xoom (medium density large but 1280x800 res) (160 dpi):
layout-xlarge (800 x 1280)
layout-xlarge-land (1280 x 800)
If outcome display in Graphical layout best matches with all other, you will get same output in original device also.
You have to read below document first:- http://developer.android.com/guide/practices/screens_support.html
or
Is there a list of screen resolutions for all Android based phones and tablets?
above also hope use full to you.
