1. 本例功能： 点击Notification，打开浏览器

2. 代码：

public static void showNotification(Context context, strUrl) \{  
  
final int NOTIFY\_ID = 999;  
NotificationManager manager = (NotificationManager) context  
.getSystemService(Context.NOTIFICATION\_SERVICE);  
  
Notification myNoti = new Notification();  
  
myNoti.flags |= Notification.FLAG\_AUTO\_CANCEL;  
  
Intent intent = getBrowserAppIntent(context,strUrl);  
  
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,  
intent, PendingIntent.FLAG\_CANCEL\_CURRENT);  
  
myNoti.tickerText = "Notify";  
myNoti.icon = R.drawable.ic\_launcher;  
//myNoti.defaults = Notification.DEFAULT\_SOUND;  
myNoti.setLatestEventInfo(context,  
context.getString(R.string.app\_name), strUrl,  
pendingIntent);  
  
manager.notify(NOTIFY\_ID, myNoti);  
//manager.cancel(NOTIFY\_ID);  
  
return;  
  
\}  
  
private static Intent getBrowserAppIntent(Context context,String strUrl) \{  
ActivityInfo browserActivity = getBrowserMainActivity(context);  
if (browserActivity != null) \{  
Intent intent = new Intent();  
intent.setAction("android.intent.action.VIEW");  
Uri content\_uri\_browsers = Uri.parse(strUrl);  
intent.setData(content\_uri\_browsers);  
intent.setClassName(browserActivity.packageName, browserActivity.name);  
intent.setFlags(Intent.FLAG\_ACTIVITY\_NEW\_TASK);  
  
return intent;  
\}  
return null;  
\}

private static ActivityInfo getBrowserApp(Context context) \{  
String default\_browser = "android.intent.category.DEFAULT";  
String browsable = "android.intent.category.BROWSABLE";  
String view = "android.intent.action.VIEW";  
  
  
Intent intent = new Intent(view);  
intent.addCategory(default\_browser);  
intent.addCategory(browsable);  
Uri uri = Uri.parse("http://");  
intent.setDataAndType(uri, null);  
  
  
// 找出手机当前安装的所有浏览器程序  
List<ResolveInfo> resolveInfoList = context.getPackageManager()  
.queryIntentActivities(intent,  
PackageManager.GET\_INTENT\_FILTERS);  
  
  
if (resolveInfoList.size() > 0) \{  
ActivityInfo activityInfo = resolveInfoList.get(0).activityInfo;  
String packageName = activityInfo.packageName;  
String className = activityInfo.name;  
  
  
Log.i(TAG, "packageName " + packageName);  
Log.i(TAG, "className " + className);  
return activityInfo;  
\} else \{  
return null;  
\}  
\}

3. 补充与说明：

1） intent也可以用setCompnent来设置。

2）注意获取browser应用的方式

3) intent的各种属性的设置。
