View requires API level 14 (current min is 8)

<GridLayout

android:columnCount="4"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:id="@+id/gridContainer"

android:animateLayoutChanges="true"

/>

When I change android:columnCount="4" to android:columnCount="5" , eclipse show the error "Type View requires API level 14 (current min is 4): <GridLayout>" .

或者用

<Switch

android:id="@+id/switch1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="Switch" />

时也报类似错误，因为版本过低

Solution : just 把Manifest.xml中的<uses-sdk android:minSdkVersion="10" />改的高些试试 ，然后clean the project and rebuilt it .​
