issue in layout related to multiple screen support

Question

am developing an application which support from 2.3.3 to 4.2. here am developing an application which can support both phone and tablet. for that i created sperate layouts and saved in different folder. i tested my application with a test device X-treme 7" Internet tablet which is android 4.0.1 version. but when i test with my tablet its not take layouts from layout-large folder. but when i test with emulator which runs android 3.0 OS it takes layouts from large folder. and my doubt is that why my application is not working properly (ie, took layout properly) ??

Answer 1

The X-treme 7" Internet tablet has a resolution of 800x480. With a 7" screen, that puts the pixels per inch somewhere around 80, which falls into very low end of the ldpi scale (which is <=120ppi. To convert a resolution of 800x480 to a density independent pixel (dp) screen size, we must multiply by ldpi's scaling of 0.75, which gives us a resolution of 600dp x 360 dp.

As per the range of screen supported guide, a large screen must be at least 640dp x 480dp, therefore your X-treme 7" Internet tablet should be classified as a normal screen device, hence why it is not picking up your layout-large layouts.

You can use any number of the many apps on Google Play to confirm your tablet's screen density and what resources it should be loading.
