Android built-in applications

Intent jump to the dial-up interface, contact interface, text message interface, and other functions in the system application need to jump directly to the dial-up, contact, text message interface, and so on, find a lot of information, and tidy up it yourself. First, let's look at the dialing interface first. The Code is as follows: Intent intent = new Intent (); intent. setAction ("android. intent. action. CALL_BUTTON "); startActivity (intent); and Uri uri = Uri. parse ("tel: xxxxxx"); Intent intent = new Intent (Intent. ACTION_DIAL, uri); startActivity (intent); both of them are supported. However, if you want to jump to the application, run the following code: Intent intent = new Intent ("android. intent. action. DIAL "); intent. setClassName ("com. android. contacts "," com. android. contacts. dialtactsActivity "); go to the call history page: Intent intent = new Intent (); intent. setAction (Intent. ACTION_CALL_BUTTON); startActivity (intent); to the Contact Interface: Intent intent = new Intent (); intent. setAction (Intent. ACTION_VIEW); intent. setData (Contacts. people. CONTENT_URI); startActivity (intent); similarly, to the Application: Intent intent = new Intent ("com. android. contacts. action. LIST_STREQUENT "); intent. setClassName ("com. android. contacts "," com. android. contacts. dialtactsActivity "); call Contact Interface: Intent intent = new Intent (); intent. setAction (Intent. ACTION_PICK); intent. setData (Contacts. people. CONTENT_URI); startActivity (intent); insert the contact Intent intent = new Intent (Intent. ACTION_EDIT, Uri. parse ("content: // com. android. contacts/"+" 1 "); startActivity (intent); Intent intent = new Intent (Intent. ACTION_INSERT_OR_EDIT); intent. setType ("vnd. android. cursor. item/person "); intent. setTyp E ("vnd. android. cursor. item/contact "); intent. setType ("vnd. android. cursor. item/raw_contact "); intent. putExtra (android. provider. contactsContract. intents. insert. NAME, name); intent. putExtra (android. provider. contactsContract. intents. insert. COMPANY, company); intent. putExtra (android. provider. contactsContract. intents. insert. PHONE, tel); intent. putExtra (android. provider. contactsContract. intents. insert. PHO NE_TYPE, 3); to the text message interface: Intent intent = new Intent (Intent. ACTION_VIEW); intent. setType ("vnd. android-dir/mms-sms "); // intent. setData (Uri. parse ("content: // mms-sms/conversations/"); // This is the number startActivity (intent); to the application: Intent intent = new Intent ("android. intent. action. CONVERSATION "); startActivity (intent); The following are other methods found online: 1. search for Intent intent = new Intent (); intent from google. setAction (Intent. ACTION_WEB_SEARCH); intent. PutExtra (SearchManager. QUERY, "searchString") startActivity (intent); 2. browse webpage Uri uri = Uri. parse ("http://www.google.com"); Intent it = new Intent (Intent. ACTION_VIEW, uri); startActivity (it); 3. show map Uri uri = Uri. parse ("geo: 38.899533,-77.036476"); Intent it = new Intent (Intent. action_VIEW, uri); startActivity (it); 4. path Planning Uri uri = Uri. parse ("http://maps.google.com/maps? F = dsaddr = startLat % 20 startLng & daddr = endLat % 20 endLng & hl = en "); Intent it = new Intent (Intent. ACTION_VIEW, URI); startActivity (it); 5. call Uri uri = Uri. parse ("tel: xxxxxx"); Intent it = new Intent (Intent. ACTION_DIAL, uri); startActivity (it); and uri = Uri. parse ("tel:" + number); intent = new Intent (Intent. ACTION_CALL, uri); startActivity (intent); you can test it by yourself. 6. intent it = new Intent (Intent. ACTION_VIEW); it. putExtra ("sms_body", "The SMS text"); it. setType ("vnd. android-dir/mms-sms "); startActivity (it); and uri = Uri. parse ("smsto:" + number of the recipient of the message to be sent); intent = new Intent (Intent. ACTION_SENDTO, uri); startActivity (intent); and mIntent = new Intent (Intent. ACTION_VIEW); mIntent. putExtra ("address", c. getString (c. getColumnIndex (column); mIntent. setType ("vnd. androi D-dir/mms-sms "); startActivity (mIntent); 7. send SMS Uri uri = Uri. parse ("Maid: 0800000123"); Intent it = new Intent (Intent. ACTION_SENDTO, uri); it. putExtra ("sms_body", "The SMS text"); startActivity (it); String body = "this is sms demo"; Intent mmsintent = new Intent (Intent. ACTION_SENDTO, Uri. fromParts ("smsto", number, null); mmsintent. putExtra (Messaging. KEY_ACTION_SENDTO_MESSAGE_BODY, body); mmsintent. putExtr A (Messaging. KEY_ACTION_SENDTO_COMPOSE_MODE, true); mmsintent. putExtra (Messaging. KEY_ACTION_SENDTO_EXIT_ON_SENT, true); startActivity (mmsintent); 8. send MMS Uri uri = Uri. parse ("content: // media/external/images/media/23"); Intent it = new Intent (Intent. ACTION_SEND); it. putExtra ("sms_body", "some text"); it. putExtra (Intent. EXTRA_STREAM, uri); it. setType ("image/png"); startActivity (it); StringBuilder sb = new Strin GBuilder (); sb. append ("file: //"); sb. append (fd. getAbsoluteFile (); Intent intent = new Intent (Intent. ACTION_SENDTO, Uri. fromParts ("mmsto", number, null); // Below extra datas are all optional. intent. putExtra (Messaging. KEY_ACTION_SENDTO_MESSAGE_SUBJECT, subject); intent. putExtra (Messaging. KEY_ACTION_SENDTO_MESSAGE_BODY, body); intent. putExtra (Messaging. KEY_ACTION_SENDTO_CONTENT_URI, sb. toString (); inten T. putExtra (Messaging. KEY_ACTION_SENDTO_COMPOSE_MODE, composeMode); intent. putExtra (Messaging. KEY_ACTION_SENDTO_EXIT_ON_SENT, exitOnSent); startActivity (intent); 9. send EmailUri uri = Uri. parse ("mailto: xxx@abc.com"); Intent it = new Intent (Intent. ACTION_SENDTO, uri); startActivity (it); Intent it = new Intent (Intent. ACTION_SEND); it. putExtra (Intent. EXTRA_EMAIL, "me@abc.com"); it. putExtra (Intent. EXTRA_TEXT, "T He email body text "); it. setType ("text/plain"); startActivity (Intent. createChooser (it, "Choose Email Client"); Intent it = new Intent (Intent. ACTION_SEND); String [] tos = {"me@abc.com"}; String [] ccs = {"you@abc.com"}; it. putExtra (Intent. EXTRA_EMAIL, tos); it. putExtra (Intent. EXTRA_CC, ccs); it. putExtra (Intent.

ACTION_SEND); it. putExtra (Intent. EXTRA_SUBJECT, "The email subject text"); it. putExtra (Intent. EXTRA_STREAM, "file: // sdcard/mysong.mp3"); sendIntent. setType ("audio/mp3"); startActivity (Intent. createChooser (it, "Choose Email Client"); 10. play multimedia Intent it = new Intent (Intent. ACTION_VIEW); Ur I uri = Uri. parse ("file: // sdcard/song.mp3"); it. setDataAndType (uri, "audio/mp3"); startActivity (it); Uri uri = Uri. withAppendedPath (MediaStore. audio. media.
