Apps No resource identifier found for attribute

I am getting below error. I want to filter out game in android app store based on device resolution. I mam getting error msg in below line in AndroidManifest.xml

<supports-screens android:requiresSmallestWidthDp="480"
android:compatibleWidthLimitDp="1024" />

Error Msg:- No resource identifier found for attribute 'requiresSmallestWidthDp' in package 'android

No resource identifier found for attribute 'compatibleWidthLimitDp' in package 'android'

Can any one please suggest where am i doing mistake ?



Thread starter
I have fixed this issue. Thanks for your response. But my main problem is still same.
If i am giving below snippets then after uploading game in app store those device list should not come but still I am getting all those device list which is having 320*480 resolution.
<supports-screens android:requiresSmallestWidthDp="800" android:compatibleWidthLimitDp="1024"/> I was surprised with this output why it is happening. Is am i missing anything in manifest xml file ? Please suggest me. Because of this problem only i am not able to release game in market. Waiting from last week to resolve this issue.
