Question

What is the difference between explicit and implicit activity call in android? If you explain the answer with a simple example will be good.

Answer 1

Implicit intent doesn't specify the component. Intent provides the information of a component

Intent intent=new Intent(Intent.ACTION_VIEW);  
intent.setData(Uri.parse("http://www.google.com"));
startActivity(intent); 

whereas, Explicit intent specify the component. The intent provides information about the class.

 Intent i = new Intent(this, ClassB.class);  
 startActivity(i);
