Question

I read this somewhere and I am little confused

“if your application explicitly supports those screens ( true) or
requires “compatibility mode” assistance ( false).”

it is about the supports-screens in manifest

<supports-screens
android:largeScreens="false"
android:normalScreens="true"
android:smallScreens="false"
android:anyDensity="true"
/>

I far as understood if I say I do not want to support large and small screen my application will be still available on the market for phones with large and small screen and also the app will be able to be run on such devices. Only the screen will be draw according the compatibility mode… Did I get it right ?

well I expected that if I sat I do not support small screen I do not want my app to be able to be install on device with small screen…

How can I prohibit the installation on devices with small screen ?

Answer 1

Market filters will help you to prevent Market visibility for devices with small screens. Have a look at <compatible-screens>.
