Pass Image url through intent to a new activity

I am new to android and currently facing some difficulties. I have an imageview in which I have loaded a url, I want to pass its url (image_url) via intent to the new activity when the user clicks on the image(imageview). in sending activity (//log.d shows the correct image_url)

    ImageView my_image = (ImageView) findViewById(R.id.single_image);
    my_image.setClickable(true);        
    my_image.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent i = new Intent(getApplicationContext(), SingleImage.class);
            i.putExtra("image_url", image_url);
            startActivity(i);
        }
    });

In the receiving activity:

   setContentView(R.layout.image);
    Intent i = getIntent();
    id= i.getStringExtra(image_url);

in the receiving activity I am not receiving the image url that I passed through the sending activity. I would really appreciated it if someone can help

Maybe you can try:

Intent i = getIntent();
id = i.getExtras().getString("image_url");

Passing data through intents is in the form putExtra (String name, String value) with 

public Intent putExtra (String name, String value)
Parameters
name    = The name of the extra data, with package prefix.
value   = The String data value.

When you try to get the passed data, you can use getStringExtra (String name) where

public String getStringExtra (String name)
Parameters
name    = The name of the desired item.

So when you getExtras, you have to use the String name - not a variable. (For your case: i.getStringExtra("image_url"); instead of i.getStringExtra(image_url);)

See Android documentation.
