Open Picture stored in res/drawable with buildin Android Image Viewer

is it possible to open an picture, which is stored in the res/drawable folder with the Android build in Image Viewer? I don't get it work. I tried the follwoing way

B开发者_开发百科utton ButtonPhase2 = (Button) findViewById(R.id.button1);
    ButtonPhase2.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {

            Intent myIntent = new Intent(android.content.Intent.ACTION_VIEW);
            myIntent.setData(Uri.parse("android.resource://de.test.app/" + R.drawable.testbild));
            myIntent.setType("image/png");
            startActivityForResult(myIntent, 1);

        }

    });

But I get the Error:

Unable to start Activity ComponentInfo{com.android.gallery/com.android.camera.ViewImage}: java.lang.nullPointerException

I think it is the wrong path?

ya you can do i by this way: first you need to declare your layout in xml

xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:layout_width="fill_parent"
    android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"
    android:gravity="center" android:orientation="horizontal">
    <ImageButton android:id="@+id/anim_btn_play"
        android:layout_width="155dp" android:layout_height="80dp"
        android:layout_marginLeft="260dp" android:layout_marginTop="150dp"
        >
    </ImageButton>

</LinearLayout>

Java file:

ImageButton tns_imgv_back;
@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.touch_and_show);
        {

        tns_imgv_back= (ImageButton)findViewById(R.id.anim_btn_play)
        tns_imgv_back.setImageResource(R.drawable.icon);
             anim_btn_play11.setOnClickListener(new View.OnClickListener() {
                public void onClick(View v) {


                                       // you can do any thing over here when you click it will fire

                                            }
            });

    }}
