android - Broadcast Receiver 每 5 分钟获取一次 wifi 信号

Question

friend

我在这里很新，对于 Android 也是如此。我想知道是否可以每 5 -10 分钟获得一次 Wifi 信号，我听说我们可以使用广播接收器，但我不知道是否可以每 5 或 10 分钟刷新一次

谢谢

是的，你可以。

    AlarmManager service = (AlarmManager) context
        .getSystemService(Context.ALARM_SERVICE);
    Intent i = new Intent(context, StatusQueryServiceStartReceiver.class);
    // Schedule the alarm!If there is already an alarm scheduled for the same IntentSender, it will first be canceled.
    PendingIntent pending = PendingIntent.getBroadcast(context, 0, i,
        PendingIntent.FLAG_CANCEL_CURRENT);
    // InexactRepeating allows Android to optimize the energy consumption
    service.setInexactRepeating(AlarmManager.RTC_WAKEUP,
        0,//cal.getTimeInMillis(), 
        REPEAT_TIME, pending);
    // service.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
    // REPEAT_TIME, pending);

StatusQueryServiceStartReceiver 是一个广播接收器
