Check box

I have a strange stack trace from my application on the Android market. I have a view switch that contains two views, one of which contains a checkbox.

I get this AdDetailView stack trace without a special view.

  android.view.InflateException: Binary XML file line #29: Error inflating class android.widget.CheckBox
  at android.view.LayoutInflater.createView(LayoutInflater.java:513)
  at com.android.internal.policy.impl.PhoneLayoutInflater.onCreateView(PhoneLayoutInflater.java:56)
  at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:563)

  at com.yakaz.view.AdDetailView.init(AdDetailView.java:67)
  at com.yakaz.view.AdDetailView.<init>(AdDetailView.java:78)

This happens in the following constructor of the form:

private void init(Context context) {
    LayoutInflater li = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    li.inflate(R.layout.ad_detail_view, this);
    setOrientation(LinearLayout.VERTICAL);
}

public AdDetailView(Context context, AttributeSet attrs) {
    super(context, attrs);
    init(context);
}

Line 67 is the inflation line.

The problem is that I cannot reproduce the problem on an emulator or device. Any pointers?

Here is the ad_detail_view.xml ad

style.xml:

here is another layout that is like the same exception raised on some device:

<?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:gravity="left|center_vertical" style="@style/TopBar"
        android:id="@+id/titlebar">
        <ImageView android:src="@drawable/logo" android:layout_width="wrap_content"
        android:layout_height="wrap_content" android:background="@null"
        android:layout_alignParentLeft="true" />

        <FrameLayout android:layout_width="wrap_content"
        android:layout_height="wrap_content" android:layout_centerVertical="true"
        android:paddingLeft="8dp" android:id="@+id/search_progressbar"
        android:visibility="gone">
            <ProgressBar android:layout_width="wrap_content"
            android:layout_height="wrap_content" 
            style="@style/ProgressBarMedium" />
        </FrameLayout>

    <LinearLayout android:id="@+id/buttons_container"
    android:gravity="right|center_vertical" android:layout_width="fill_parent"
    android:layout_height="fill_parent" />
</LinearLayout>
    ....
</LinearLayout>
</LinearLayout>

code that throws an exception:

public static CompoundButton addTitleBarCompoundButton(Context context,
        View titleBar, CharSequence label, boolean isChecked) {
    if (!(titleBar instanceof ViewGroup))
        return null;

    ViewGroup group = (ViewGroup) titleBar
            .findViewById(R.id.buttons_container);

    // We attach to root during the inflating process othersize layout_
    // parameters in the style are ignored
    LayoutInflater.from(context).inflate(R.layout.topbar_toggle_button,
            group, true);

    // Get the result, which is the last child of the group
    CompoundButton result = (CompoundButton) group.getChildAt(group
            .getChildCount() - 1);
    result.setChecked(isChecked);

    // Set the text
    result.setText(label);
    return result;
}

topbar_toggle_button.xml:

<?xml version="1.0" encoding="utf-8"?>
<CheckBox xmlns:android="http://schemas.android.com/apk/res/android" style="@style/BarButton.Toggle"/>
