Android AlarmManager先发射一次，然后每秒重复发射。。。。。为什么？

我正在使用一个离线任务，因此我必须每隔5分钟在Backgord中调用

Webservice

。因此，我使用了

AlarmManager

第一次

AlarmManager

On time（启动5分钟后）启动，但启动后每几秒钟就会启动一次，我不知道为什么

我只想让火警经理每5分钟

请帮忙

这是启动计时器的代码

public void startOfflineDateAlarm() {

    //* For Start Offline Sync Timer*//
    Intent intentAlarm = new Intent(this, AlarmReceiver.class);
    AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    alarmManager.set(AlarmManager.RTC_WAKEUP, Constant.offlineDataAlarmTime,
            PendingIntent.getBroadcast(this, 1, intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT));
    Log.e(TAG, "ALARM START");

    saveOfflineTables(getApplicationContext());
}

这是

BroadcastReceiver

，我在这里执行调用

Webservices

的任务

我还在

BroadcastReceiver

中添加了启动

AlarmManager

的代码，以便在接下来的5分钟内再次启动AlarmManager。（如果我在这方面出错，请纠正我。）

您需要使用“重复报警”来引用此内容。请不要只是将代码转储为答案，还要包括一个解释。@Jaspreet Kaur，我必须在开始时间或AlarmReceiver中用代码替换此内容，或者两者兼而有之？我只需在阅读他的问题后写出所需的答案。并在答案中写下评论。inside startoffiredatealarm方法。您没有设置重复报警。@Jaspreet Kaur，我在成功登录后的登录活动中使用此方法（StartOfflineDataAlarm），但在登录此活动后，我使用finish进行此操作，因此，如果确定，我只需在此方法中进行更改。

public class AlarmReceiver extends BroadcastReceiver {

    String TAG = "AlarmReceiver";
    public static PendingIntent pendingIntent;

        alarmManager.set(AlarmManager.RTC_WAKEUP,Constant.offlineDataAlarmTime, pendingIntent);
