Error Inflating Class Fragment (related to ShinobiCharts)

Question

I am getting an "Error inflating class fragment". Is it due to an error in my xml file? I have a feeling it may have something to do with the namespaces I'm using, but I'm not sure...

Here's the logcat:

And here's the XML file:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".Chartscreenactivity" >

<fragment
    class="com.shinobicontrols.charts.ChartFragment"
    android:id="@+id/chart"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

</LinearLayout>

Here's the relevant code from the activity:

ChartFragment chartFragment =
                                    (ChartFragment) getFragmentManager().findFragmentById(R.id.chart);

                            // Get the a reference to the ShinobiChart from the ChartFragment
                            ShinobiChart shinobiChart = chartFragment.getShinobiChart();

Answer 1

Although ShinobiCharts supports down to API Level 9 (Gingerbread), Fragments were only introduced in API Level 11. Therefore you need to use the support library.

From the getting started guide:

Tip: To support devices down to API 9: Android 2.3 (Gingerbread) you will need to use SupportChartFragment instead of ChartFragment (in both the XML and the Java source). Additionally, you will need to change the ShinobiQuickStartActivity to extend FragmentActivity instead of Activity and use the getSupportFragmentManager() method instead of getFragmentManager(). Your project will need to reference the Android Support Library to do this.
