Вроде ничего криминального не делал. Создался лэйоут по умолчканию. На него положил ImageView. Создал класс TouchView.
package com.example.touchview;
import android.content.Context;
import android.view.SurfaceView;
public class TouchView extends SurfaceView{
public TouchView(Context context) {
super(context);
}
}
Добавил на лэйоут описание объекта
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/rlMain"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".BlockerActivity" >
<com.example.lookatme.TouchView
android:id="@+id/tvPaint"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignTop="@+id/ivCenter"
android:layout_marginTop="14dp" />
<ImageView
android:id="@+id/ivCenter"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:src="@drawable/ic_launcher" android:contentDescription="TODO"/>
</RelativeLayout>
так приложение рушится на момент setContentView(R.layout.activity_brocker) . В LogCat ничего вразумительного:

что за причина такого падения? что делаю не так?
Без TouchView в лэйоуте все запускается отлично.
