how to ViewFlipper addView or removeView after autoStart set to true - viewflipper

Question

For my app, I have lots of images(from url not from phone memory) required to be shown as slideshow. I am using ViewFlipper for this. I am getting this images from url and adding them in viewFlipper. Problem is when i add 5-6 images it works fine but for more than 5-6 it goes into OutOfMemory error.
I think, this can be done if we can somehow do something like this..
1. add some set of images to ViewFlipper
2. startFlipping, remove view after showing that image/view,
3. add more images.
Not sure if it can be done using viewFlipper or are there any other way ?
Sample Code of my AutoSlideShow:
import java.io.IOException;
import java.io.InputStream;
import java.net.MalformedURLException;
import java.net.URL;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.WindowManager;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.ViewFlipper;
public class AutoSlideShow extends Activity {
ViewFlipper viewFlipper = null;
Button pauseButton;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_auto_slide_show);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
Intent intent = getIntent();
String[] allUrls = intent.getExtras().getStringArray("allImageUrls");
viewFlipper = (ViewFlipper) findViewById(R.id.viewFlipper);
viewFlipper.setFlipInterval(2000);
viewFlipper.setAutoStart(true);
for (int i = 0; i < allUrls.length; i++) {
setFlipperImage(allUrls[i]);
}
pauseButton = (Button) findViewById(R.id.pauseButton);
pauseButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (pauseButton.getText().equals("Resume")) {
viewFlipper.startFlipping();
pauseButton.setText("Pause");
} else {
viewFlipper.stopFlipping();
pauseButton.setText("Resume");
}
}
});
}
private void setFlipperImage(String url) {
ImageView image = new ImageView(getApplicationContext());
Bitmap bitmap = null;
try {
InputStream content = (InputStream) new URL(url).getContent();
bitmap = BitmapFactory.decodeStream(content);
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
image.setImageBitmap(bitmap);
viewFlipper.addView(image);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.auto_slide_show, menu);
return true;
}
}
