Question

I am seeing a class not found exception for android.view.fragment although I am using the compatibility library. Compiles fine but crashes. Is there another package that I should use when pre 3.0? I already changed all fragment classes to android.support.v4.app.Frament but it still crashes because of what is in the layout. My SDK is 4.03 but device is 2.3.

Here is layout

    <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
<fragment
    android:id="@+id/frag_series"
    android:layout_width="200dip"
    android:layout_height="match_parent"
    android:layout_marginTop="?android:attr/actionBarSize"
    class="com.authorwjf.hello_fragments.ListFrag" />
<fragment
    android:id="@+id/frag_capt"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    class="com.authorwjf.hello_fragments.DetailFrag" />
</LinearLayout>

Answer 1

Do the same in your layout XML:

<android.support.v4.app.Fragment />

Also, note the capitalization.
