ImageView I can't display image

I've created very simple android application which display image. Code:

public class MainActivity extends Activity {

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

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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"
    tools:context=".MainActivity" >


    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@+id/textView1"
        android:scaleType="matrix"
        android:src="@drawable/img_big_size"
    />

</RelativeLayout>

Furthermore I have two the same pictures ,first img_big_size.jpg(size 468 KB) and second img_small_size.jpg(size 192 KB). The first image has a higher resolution so it takes more memory than second image. When I try display second image(img_small_size.jpg) application works fine and display image. But when I try display fist image(img_small_size.jpg) application don't display image only show black screen. Why my application can't display first image?? How display first image?

I want to display first image because when I zoom image first the picture is more clear than second image.

Your big image size dimen is : 1571x2166

OpenGLRenderer hardware Acceleration cannot handle bitmap larger than 2048x2048. You can try to disable hardware Acceleration by defining android:hardwareAccelerated="false" inside in AndroidManifest.xml file.

<application
    android:hardwareAccelerated="false"
    android:largeHeap="true" >

or for your best performance, you can resize your image before displaying it. reserving large heap will significantly decrease your app performance.
