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 ,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:admin@3gstdy.com”);
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 = { ” };
String[] ccs = { ” };
intent.putExtra(Intent.EXTRA_EMAIL, tos);
intent.putExtra(Intent.EXTRA_CC, ccs);
intent.putExtra(Intent.EXTRA_TEXT, “I come from ”);
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 ”);
intent.setType(“vnd. -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 ”);
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 ”);
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. .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
