I am really confused about uri and i am not getting the concept of uri at all. I researched online and i am really getting confused. I am reading the wrox android programming book and they mentioned the following code and i dont understand the role of uri.parse() method.

Java

Intent intent = new Intent();
 intent.getdata(uri.parse(editext1.gettext().toString());

//what role does the uri.parse() do in the above code?

I have also seen something like this uri.parse("http://www.google.com")....what does it mean?

I am terribly confused and can someone explain me in simple terms what is the concept of uri and what does the parse method do?

In Android that means a URI, Uniform Resource Identifier[^]. The Android API contains the definition as, Uri[^] in android.net package.

But... The one in your code doesn't look like that, Java is a case-sensitive language, so Uri is not equal to uri. They have different meanings, and since parse is a static function, your code won't compile. Please change it to

Java

// Changed 
//    1. getdata to getData
//    2. uri to Uri
//    3. gettext to getText
Intent intent = new Intent();
intent.getData(Uri.parse(editext1.getText().toString());

You must keep the names as they are, otherwise they will cause a problem in your code. I hope the code would work (if edittext1 is defined as it is written). Plus, read the resources provided to learn more about Uri or other objects. You will find a lot of more resources on official Android documentation, do visit them. :)
