1、呼叫web瀏覽器 

uri uri = uri.parse(""); 

intent intent = new intent(intent.action_view ,uri); 

startactivity(intent); 

2、在地圖上顯示某個座標  

uri uri = uri.parse("geo:21.803233,-53.829831"); 

intent intent = new intent(intent.action_view, uri); 

startactivity(intent); 

3、顯示路徑

uri uri = uri.parse(""); 

intent intent = new intent(intent.action_view, uri); 

startactivity(intent);

4、呼叫撥打**介面 

uri uri = uri.parse("tel:10086"); 

intent intent = new intent(intent.action_dial, uri); 

startactivity(intent); 

5、直接撥打**

需要新增許可權 

uri uri = uri.parse("tel.10086"); 

intent intent =new intent(intent.action_call, uri);

6、傳送簡訊或彩信 

intent intent = new intent(intent.action_view);

intent.settype("vnd.android-dir/mms-sms"); 

startactivity(intent);

7、傳送簡訊   

uri uri = uri.parse("smsto:10000"); 

intent intent = new intent(intent.action_sendto, uri); 

intent.putextra("sms_body", "haha"); 

startactivity(intent); 

8、傳送彩信 

uri uri = uri.parse("content://media/external/images/media/23"); 

intent intent = new intent(intent.action_send); 

intent.putextra("sms_body", "some text"); 

intent.putextra(intent.extra_stream, uri); 

intent.settype("image/png"); 

startactivity(intent);

或者intent intent = new intent(intent.action_send); 

intent.setclassname("com.android.mms", "com.android.mms.ui.composemessageactivity");

intent.putextra("sms_body", "彩信內容");

uri uri = uri.parse("mailto:***@foxmail.com"); 

intent intent = new intent(intent.action_sendto, uri); 

startactivity(intent);

10、傳送郵件  

intent intent = new intent(intent.action_send); 

intent.putextra(intent.extra_email, ***@foxmail.com); 

intent.putextra(intent.extra_text, "the email body text"); 

intent.settype("text/plain"); 

startactivity(intent.createchooser(intent, "choose email client"));

或者intent intent = new intent(intent.action_send); 

string tos = ; 

string ccs = ; 

intent.putextra(intent.extra_email, tos); 

intent.putextra(intent.extra_cc, ccs); 

intent.putextra(intent.extra_text, "the email body text"); 

intent.putextra(intent.extra_subject, "the email subject text"); 

intent.settype("message/rfc822"); 

startactivity(intent.createchooser(intent, "choose email client")); 

intent intent = new intent(intent.action_view); 

uri uri = uri.parse(file:///sdcard/musics/someonelikeyou.***); 

intent.setdataandtype(uri, "audio/***"); 

startactivity(intent); 

intent intent = new intent(intent.action_view, uri); 

startactivity(intent);

12、解除安裝apk 

uri uri = uri.fromparts("package", strpackagename, null); 

intent intent = new intent(intent.action_delete, uri); 

startactivity(intent); 

或者uri uninstalluri = uri.fromparts("package", "***", null); 

intent intent = new intent(intent.action_delete, uninstalluri); 

13、安裝apk

uri installuri = uri.fromparts("package", "***", null); 

intent intent = new intent(intent.action_package_added, installuri);

uri playuri = uri.parse("file:///sdcard/download/sth.***"); 

intent intent = new intent(intent.action_view, playuri); 

15、傳送附件

intent intent = new intent(intent.action_send); 

intent.putextra(intent.extra_subject, "the email subject text"); 

intent.putextra(intent.extra_stream, "file:///sdcard/test.***");

startactivity(intent.createchooser(intent, "choose email client"));

startactivity(intent);
