So depending on the Android versions we want to support, there's multiple Android support libraries v4, v5 and vX. So far we have been careless with these in our fragment code. In some areas, we use v4, other areas use v7. Each version supports different Android OS versions.

public class ResultDetailActivity extends ActionBarActivity {
is v7 code, we should decide if we want to mix versions like this.
