i'm trying create android application using xamarin , visual studio. strange error while using setsupportactionbar function.
this xml code:
<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <android.support.v7.widget.toolbar android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="wrap_content" android:minheight="?attr/actionbarsize" android:background="?attr/colorprimary" app:theme="@style/themeoverlay.appcompat.dark.actionbar" app:popuptheme="@style/themeoverlay.appcompat.dark" /> <android.support.v4.widget.drawerlayout android:id="@+id/drawer_layout" android:layout_width="match_parent" android:layout_height="match_parent"> <relativelayout android:layout_width="match_parent" android:layout_height="match_parent"> . . . </relativelayout> <listview android:id="@+id/left_drawer" android:layout_width="240dp" android:layout_height="match_parent" android:layout_gravity="start" android:choicemode="singlechoice" android:divider="#818181" android:dividerheight="1dp" android:background="#e3f2fd" /> </android.support.v4.widget.drawerlayout> </linearlayout> and c# file code:

before , don't recall changing can make crash.
can give me tip do?
thank in advance!
looks theme not correctly configured.
either use in theme (see related answer)
<item name="windowactionbar">false</item>
or derive theme without action bar (see related answer), example:
theme.appcompat.light.noactionbar
