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。
