I am trying to run my first android app. I follow tutorial 'My first App' on developer.android.com.
activity_main.xml is simple:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
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=".MainActivity" >
<EditText
android:id="@+id/edit_message"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:hint="@string/edit_message" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="@string/send_button" />
</LinearLayout>
MainActivity.java is as default.
The problem is that when I run my Andoid app it does open new virtual device but with black screen and a few buttons on the right pane. So there is nothing displayed from my activity_main.xml.
In console I see such output:

What can be wrong?
Thank you!
