Question

I’m implementing the SherlockActionBar for an Android application, but I wanna maintain a backward compatibility with pre Honeycomb devices.

This is the sample code:

package com.sherlockbar.example;

import android.os.Bundle;
import android.support.v4.app.FragmentTransaction;
import android.widget.TextView;

import com.actionbarsherlock.app.ActionBar;
import com.actionbarsherlock.app.ActionBar.Tab;
import com.actionbarsherlock.app.SherlockActivity;

public class SherlockExampleActivity extends SherlockActivity implements ActionBar.TabListener {
    private TextView mSelected;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.tab_navigation);
        mSelected = (TextView) findViewById(R.id.text);

        getSupportActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
        for (int i = 1; i <= 3; i++) {
            ActionBar.Tab tab = getSupportActionBar().newTab();
            tab.setText("Tab " + i);
            tab.setTabListener(this);
            getSupportActionBar().addTab(tab);
        }
    }

    @Override
    public void onTabReselected(Tab tab, FragmentTransaction transaction) {
    }

    @Override
    public void onTabSelected(Tab tab, FragmentTransaction transaction) {
        mSelected.setText("Selected: " + tab.getText());
    }

    @Override
    public void onTabUnselected(Tab tab, FragmentTransaction transaction) {
    }
}

For 4.0 devices this works perfect, but for Honeycomb it doesn’t work -I get the following error:

E/AndroidRuntime(2363): Caused by: java.lang.IllegalStateException:
You must use Theme.Sherlock, Theme.Sherlock.Light,
Theme.Sherlock.Light.DarkActionBar, or a derivative.

In the manifest I tried to establish that them but it’s not in the suggested list, plus if I write it, I still get the error.

How do I set the bar up for Honeycomb devices please?

Thanks a lot in advance!

Answer 1

Are you compiling against 4.0? You need to target the Android 4.0 sdk in order for it to compile correctly (even if you’re running on < 4.0).
