How can I make sure that newer functions (API level 12) become available for an older API (level 7)? I want to use the RadioButtons block. I am doing this in gridLayout. I use Eclipse Juno for editing, the JDK compliance level for the Java compiler is set to 1.6.
After saving the layout containing gridLayout using RadioButtons, he warned that it was not available in API 7, so he asked if I wanted to decide what I answered “yes”.
I checked that instead of using GridLayout, this type (right?) Is called android.support.v7.widget.GridLayout in the layout file. A node 'gridlayout_v7' with an empty src subdirectory was placed at the root of the bij Eclipse project.
Android v.11 support library installed.
However, when I run the program on a virtual device (Android 2.1 device), LogCat returns the following errors and warnings:

The error log does not show errors.
The console shows the following (no errors):

Clicking on RadioButton on the virtual device (after the first launch of the application for display) leads to the following LogCat errors:

After selecting a radio object, it is not possible to deselect by clicking it again or by selecting a different radio object in the same group (the same GridLayout).
What is wrong, how to solve?
