本文提供了多个 Android Intent 的使用案例，包括显示网页、地图定位、路径规划、拨打电话、发送短信及邮件等常见操作，并展示了如何利用 Intent 实现多媒体播放、卸载应用等功能。

显示网页:

Uri uri = Uri.parse(”http://www.google.com”);
Intent it = new Intent(Intent.ACTION_VIEW,uri);
startActivity(it);
显示地图:

Uri uri = Uri.parse(”geo:38.899533,-77.036476″);
Intent it = new Intent(Intent.Action_VIEW,uri);
startActivity(it);
路径规划:

Uri uri = Uri.parse(”http://maps.google.com/maps?f=dsaddr=startLat%20startLng&daddr=endLat%20endLng&hl=en”);
Intent it = new Intent(Intent.ACTION_VIEW,URI);
startActivity(it);
拨打电话:
调用拨号程序

Uri uri = Uri.parse(”tel:xxxxxx”);
Intent it = new Intent(Intent.ACTION_DIAL, uri);
startActivity(it);
Uri uri = Uri.parse(”tel.xxxxxx”);
Intent it =new Intent(Intent.ACTION_CALL,uri);
要使用这个必须在配置文件中加入
发送SMS/MMS

Intent it = new Intent(Intent.ACTION_VIEW);
it.putExtra(”sms_body”, “The SMS text”);
