Intent usage on the first day

Intent usage generally has three types

For other usage, you must first configure the data tag in <intent-filter> !!! So that ThirdActivity can respond to intent of all http protocols

The instance code is as follows: Intent intent = new Intent (Intent. ACTION_VIEW); intent. setData (Uri. parse ("http://www.baidu.com"); startActivity (intent );

The telephone protocol is tel.

Intent intent = new Intent (Intent. ACTION_DIAL); intent. setData (Uri. parse ("tel: 10086"); startActivity (intent );
