Why am i not able to get Extras from the intent this way?

Question

In the previous Activity i did this:

int entryId = 10;
intent.putExtra("entry_id", entryId);

then in the resultant Activity

First i tried this:

entry_id = this.getIntent().getExtras().getInt("entry_id");

it always gives me the default value 0

But i changed to this:

entry_id = this.getIntent().getIntExtra("entry_id", 1);

it gives the correct value (10).

why is it so?

define constants for your intent extras name. That will avoid you spelling errors like this one. — njzk2, Sep 03 '12 at 09:33

Try this entry_id = this.getIntent().getIntExtra("entry_Id", 1);

The change is use of I in id. It's capital in your get()

The reason is key is case sensitive

Chanage entry_Id to entry_id in your first case.

You should use entry_id instead of entry_Id
