Write yourself your own Clipboard compat class, for example:

import android.annotation.SuppressLint;
import android.content.ClipData;
import android.content.Context;
import android.net.Uri;


public class ClipboardCompat {
    private android.content.ClipboardManager currentCM=null;
    private android.text.ClipboardManager legacyCM=null;

    public ClipboardCompat() {
        if(android.os.Build.VERSION.SDK_INT >= 11 && currentCM == null) {
            currentCM = (android.content.ClipboardManager)
                    [getsomecontext].getSystemService(Context.CLIPBOARD_SERVICE);
        }
        else if(legacyCM == null)
        {
            legacyCM = (android.content.ClipboardManager)
                    [getsomecontext].getSystemService(Context.CLIPBOARD_SERVICE);
        }
    }

    @SuppressLint("NewApi")
    public String getText() {
        if(currentCM!=null) {
            try{
                return currentCM.getPrimaryClip().getItemAt(0).getText().toString();
            } catch (NullPointerException e) {
                return null;
            }
        }
        else
        {
            try{
                return legacyCM.getText().toString();
            } catch (NullPointerException e) {
                return null;
            }
        }
    }

    @SuppressLint("NewApi")
    public Uri getUri() {
        if(currentCM!=null) {
            try{
                return currentCM.getPrimaryClip().getItemAt(0).getUri();
            } catch (NullPointerException e) {
                return null;
            }
        }
        else
        {
            return null;
        }
    }

    @SuppressLint("NewApi")
    public void set(String name, String s) {
        if(currentCM!=null) {
            ClipData clip = ClipData.newPlainText(name, s);
            currentCM.setPrimaryClip(clip);
        }
        else
        {
            legacyCM.setText(s);
        }
    }

    @SuppressLint("NewApi")
    public void set(String name, Uri u) {
        if(currentCM!=null) {
            ClipData clip = ClipData.newRawUri(name, u);
            currentCM.setPrimaryClip(clip);
        }
        else
        {
            legacyCM.setText(u.toString());
        }
    }
}
