(Original) Android timing operation

In actual development, do some timing operations

For example, execute a certain code after three minutes

Usually at this time we will first think of Timer

But if this time is longer

For example, to execute after 30 days

Only Timer is not enough.

Here is a quick and convenient way

Is to use the AlarmManager class

System timing service

It is also very simple to use, just cooperate with the broadcast

The specific code is as follows:

//30天以后启动广播

//获取系统服务
AlarmManager manager = (AlarmManager)MyService.this.getSystemService(Activity.ALARM_SERVICE);
//设置定时时长
long anHour = 30l * 60 * 60 * 1000 * 24;//30天以后
long triggerAtTime = System.currentTimeMillis() + anHour;
Intent i = new Intent(MyService.this, TimeReceiver.class);
//发送广播
PendingIntent pi = PendingIntent.getBroadcast(MyService.this, 0, i, 0);
//发送定时消息
manager.set(AlarmManager.RTC, triggerAtTime, pi);

When timing operations are needed

Set the corresponding duration to send the broadcast

Then you can perform the operation in the broadcast by yourself
