[置顶] android之Notification版本兼容性问题

         首先先来创建一个notification提示

//概要

String tickerText = context.getResources().getText(R.string.app_name).toString()+"发现新版本,建议您更新!";

//标题

String title = context.getResources().getText(R.string.app_name).toString()+"更新";

//内容

String content= "点击更新"+context.getResources().getText(R.string.app_name).toString();

//logo

int icon = R.drawable.logo;

Notification notification = new Notification(icon, tickerText, System.currentTimeMillis());

//打开一个service意图

Intent updateinte = new Intent(context,UpdateService.class);

//包装service意图

PendingIntent pendingIntent = PendingIntent.getService(context, 0, updateinte, 0);

notification.setLatestEventInfo(context, title, content, pendingIntent);

notification.defaults = Notification.DEFAULT_SOUND;

notification.flags = Notification.FLAG_AUTO_CANCEL;

NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

manager.notify(101, notification);

       接下来的更新notification中,在4.0版本以后我们只需这样即可

 

notification.setLatestEventInfo(context,"正在下载"+appName,"0%", null);

//id相同为101表示更新提示

manager.notify(101, notification);

         但是放到2.x版本中运行的时候就报错提示我们require contentIntent,所以我们需要不能将PendingIntent设置为null;需要设置一个空的intent给PendingIntent包装,再将PendingIntent设置给notification;

 

 

Intent nullIntent = new Intent();

PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, nullIntent, 0);

// 下载失败

notification.setLatestEventInfo(context,"正在下载"+appName,"0%", pendingIntent);

manager.notify(101, notification);

       这样就可以搞定,Notification的详细应用可以查看我的博客 http://blog.csdn.net/caicongyang
