Question

I am developing an app that uses fragments with the support library. The app is working and is published, but i get this error report(Only with 3.2 OS versions):

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.naviter.seeyou/com.naviter.seeyou.MenuDisplayActivity}: android.view.InflateException: Binary XML file line #19: Error inflating class

com.naviter.seeyou.DisplayFragment.onCreateView(DisplayFragment.java:57)

The Exception is thrown at the last line in the onCreateView method:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState){
    if (container == null)
        return null;
    getActivity().setTitle(R.string.Display);
    return inflater.inflate(R.layout.settings_display, container, false); //here
}

and this is the xml file:

<ListView
    android:id="@+id/listViewDisplay"
    android:layout_width="match_parent"
    android:layout_height="0dip"
    android:layout_weight="1" >

</ListView>

<LinearLayout
    android:id="@+id/rlAsDialog"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <Button
        android:id="@+id/buttonDisplayOk"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1" 
        android:text="@string/Ok" />

    <Button
        android:id="@+id/buttonDisplayCancel"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="@string/Cancel" />

</LinearLayout>
</LinearLayout>

I repeat, that the app is runnig well, i got this exception only on few devices with Android 3.2 OS. And i’m importing fragment from:

android.support.v4.app.Fragment;

Any suggestions?

Thanks.

Answer 1

I thing i solved the issue.
I was accidentally extending the class with:

DialogFragment

instead of:

Fragment

And then using a custom layout for DialogFragment. Obviously this causes problems only on Android 3.2

I also find another problem later. In the Manifest i was using the theme Theme.DeviceDefault wich was added in android api level 14 and android 3.2 obviously can’t live with this. Then i implemented a theme selector wich chooses the theme depending on the device API level.
