Android - How to use different code lines depending of Android version

Question

I have a project which is compatible with Android versions from 10(GINGERBREAD_MR1) to 17(JELLY_BEAN_MR1).

So, I would like to use setBackgroundDrawable for versions lower to 16 and setBackground from version 16 or upper.

I've tried this:

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) {
    subMessageFromToLinearLayout.setBackgroundDrawable(null);
} else {
    subMessageFromToLinearLayout.setBackground(null);
}

But, Eclipse gives me:

A warning for subMessageFromToLinearLayout.setBackgroundDrawable(null);: "The method setBackgroundDrawable(Drawable) from the type View is deprecated"

And an error for subMessageFromToLinearLayout.setBackground(null);: "Call requires API level 16 (current min is 10): android.widget.LinearLayout#setBackground"

How can I fix this errors in order I can use both lines depending of the running Android version?

Thanks in advance.

In general the most robust way makes use of class lazy loading:

static boolean isSDK17()
{
   return android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1;
}


if (isSDK17())
    xyMode_SDK17.setXyMode(context, mode);
else
    xyMode_SDK8.setXyMode(context, mode);


@TargetApi(17)
public class xyMode_SDK17
{
  static void setXyMode(Context context, boolean mode)
  {...}
}


public class xyMode_SDK8
{
  @SuppressWarnings("deprecation")
  static void setXyMode(Context context, boolean mode)
   {...}
}
