Android Fragment support , java.lang.NoSuchMethodException: Fragment(Context,AttributeSet)

Question

I try to use fragments with AndroidAnnotations and maven. It worked with Android 4.0+ , but then I tried to make it work with Android 2.3.3 and I had to use the support-v4 maven library:

<dependency>
    <groupId>com.google.android</groupId>
    <artifactId>support-v4</artifactId>
    <version>r7</version>
</dependency>

My fragment is defined as:

<android.support.v4.app.Fragment android:id="@+id/myFragment"
                                 android:layout_width="fill_parent"
                                 android:layout_height="wrap_content"
                                 class="com.bla.HeaderFragment_"/>

and My Activity extends FragmentActivity

I get this exception when I run the app:

.....

Any idea why?

Answer 1

Try <fragment> tag and name attribute for class name. Also, you've used class name as com.bla.HeaderFragment_ , seems like a typo.

<fragment android:id="@+id/myFragment"
          android:name="com.bla.HeaderFragment_"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
                                 />
