以下是常用到的Intent的URI及其示例，包含了大部分应用中用到的共用Intent。

一、打开一个网页，类别是Intent.ACTION_VIEW

Uri uri = Uri.parse(“http://blog.3gstdy.com/”);

Intent intent = new Intent(Intent.ACTION_VIEW, uri);

二、打开地图并定位到一个点

Uri uri = Uri.parse(“geo:52.76,-79.0342″);

Intent intent = new Intent(Intent.ACTION_VIEW, uri);

三、打开拨号界面 ,类型是Intent.ACTION_DIAL

Uri uri = Uri.parse(“tel:10086″);

Intent intent = new Intent(Intent.ACTION_DIAL, uri);

四、直接拨打电话,与三不同的是，这个直接拨打电话，而不是打开拨号界面

Uri uri = Uri.parse(“tel:10086″);

Intent intent = new Intent(Intent.ACTION_CALL, uri);

五、卸载一个应用，Intent的类别是Intent.ACTION_DELETE

Uri uri = Uri.fromParts(“package”, “xxx”, null);

Intent intent = new Intent(Intent.ACTION_DELETE, uri);

六、安装应用程序 ,Intent的类别是Intent.ACTION_PACKAGE_ADDED

Uri uri = Uri.fromParts(“package”, “xxx”, null);

Intent intent = new Intent(Intent.ACTION_PACKAGE_ADDED, uri);

七、播放音频文件

Uri uri = Uri.parse(“file:///sdcard/download/everything.mp3″);

Intent intent = new Intent(Intent.ACTION_VIEW, uri);

intent.setType(“audio/mp3″);

八、打开发邮件界面

Uri uri= Uri.parse(“mailto:[email protected]”);

Intent intent = new Intent(Intent.ACTION_SENDTO, uri);

九、发邮件,与八不同这里是将邮件发送出去，

Intent intent = new Intent(Intent.ACTION_SEND);

String[] tos = { “[email protected] ” };

String[] ccs = { “[email protected] ” };

intent.putExtra(Intent.EXTRA_EMAIL, tos);

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”);

//发送带附件的邮件

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”));

十、发短信

Uri uri= Uri.parse(“tel:10086″);

Intent intent = new Intent(Intent.ACTION_VIEW, uri);

intent.putExtra(“sms_body”, “I come from http://blog.3gstdy.com ”);

intent.setType(“vnd.Android -dir/mms-sms”);

十一、直接发邮件

Uri uri= Uri.parse(“smsto://100861″);

Intent intent = new Intent(Intent.ACTION_SENDTO, uri);

intent.putExtra(“sms_body”, “3g android http://blog.3gstdy.com ”);

十二、发彩信

Uri uri= Uri.parse(“content://media/external/images/media/23″);

Intent intent = new Intent(Intent.ACTION_SEND);

intent.putExtra(“sms_body”, “3g android http://blog.3gstdy.com ”);

intent.putExtra(Intent.EXTRA_STREAM, uri);

intent.setType(“image/png”);

十三、# Market 相关

1 //寻找某个应用

Uri uri = Uri.parse(“market://search?q=pname:pkg_name”);

Intent it = new Intent(Intent.ACTION_VIEW, uri);

startActivity(it);

//where pkg_name is the full package path for an application

2 //显示某个应用的相关信息

Uri uri = Uri.parse(“market://details?id=app_id”);

Intent it = new Intent(Intent.ACTION_VIEW, uri);

startActivity(it);

//where app_id is the application ID, find the ID

//by clicking on your application on Market home

//page, and notice the ID from the address bar

十四、路径规划

Uri uri = Uri.parse(“http://maps.google .com/maps?f=d&saddr=startLat%20startLng&daddr=endLat%20endLng&hl=en”);

Intent it = new Intent(Intent.ACTION_VIEW, uri);

startActivity(it);

//where startLat, startLng, endLat, endLng are a long with 6 decimals like: 50.123456
