Intent Uri and examples are often used in Android development.

The following is the commonly used intent Uri and its example, including the common intent used in most applications.
1. Open a webpage. the category is intent. action_view.
Uri uri = URI. parse ("http://blog.3gstdy.com /");
Intent intent = new intent (intent. action_view, Uri );
2. Open the map and locate a point
Uri uri = URI. parse ("Geo: 52.76,-79.0342 ″);
Intent intent = new intent (intent. action_view, Uri );
3. Open the dialing interface. The type is intent. action_dial.
Uri uri = URI. parse ("Tel: 10086 ″);
Intent intent = new intent (intent. action_dial, Uri );
4. Direct Dialing. The difference between the two is that direct dialing is not to open the dialing interface.
Uri uri = URI. parse ("Tel: 10086 ″);
Intent intent = new intent (intent. action_call, Uri );
5. Uninstall an application. The intent category is intent. action_delete.
Uri uri = URI. fromparts ("package", "XXX", null );
Intent intent = new intent (intent. action_delete, Uri );
6. Install the application. The intent category is intent. action_package_added.
Uri uri = URI. fromparts ("package", "XXX", null );
Intent intent = new intent (intent. action_package_added, Uri );
VII. play audio files
Uri uri = URI. parse ("file: // sdcard/download/everything ″);
Intent intent = new intent (intent. action_view, Uri );
Intent. settype ("audio/MP3 ″);
8. open the mail Interface
Uri uri = URI. parse ("mailto: admin@3gstdy.com ");
Intent intent = new intent (intent. action_sendto, Uri );
9. send an email. Unlike sending an email,
Intent intent = new intent (intent. action_send );
String [] TOS = {"admin@3gstdy.com "};

Intent. putextra (intent. extra_cc, CCS );
Intent. putextra (intent. extra_text, "I come from http://blog.3gstdy.com ");
Intent. putextra (intent. extra_subject, "http://blog.3gstdy.com ");
Intent. settype ("message/rfc882 ″);
Intent. createchooser (intent, "Choose email client ");
// Send an email with an attachment
Intent intent = new intent (intent. action_send );
Intent. putextra (intent. extra_subject, "the email subject text ");
Intent. putextra (intent. extra_stream, "file: // sdcard/mysong.mp3 ″);
Intent. settype ("audio/MP3 ″);
Startactivity (intent. createchooser (intent, "Choose email client "));
