[android-developers] app crashes after adding toolbar

[Roman Turzyny]

I have a really basic app, only one Activity with toolbar. Eveything works 
fine on my LG G2  (API  19) but when try to run it on tablet  Samsung 
GT-N5100( also API 19) the app crashes with an error message: Error 
inflating class android.support.v7.widget.Toolbar
I have tried cleaning my project, rebuilding it again but nothing helps. 
When i try to implent other widgets from the package ( AppCompatButton 
<https://developer.android.com/reference/android/support/v7/widget/AppCompatButton.html>)
 
it works.  I am starting to assume that device might be problem here. 
Anyway,here is my code: 

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android";
    android:layout_width="match_parent"
    android:layout_height="match_parent">

   <android.support.v7.widget.Toolbar
        android:id="@+id/my_toolbar"
        android:layout_width="match_parent"
        android:layout_height="58dp"
        android:background="?attr/colorPrimary"
        android:minHeight="?attr/actionBarSize"
        android:titleTextColor="#ffffff">

</LinearLayout>


MainActivity.java

package com.example.tomas.toolbar;

public class MainActivity extends AppCompatActivity{

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

    }
}

   build.gradle

apply plugin: 'com.android.application'

android {

    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.4.0'
