Question

我有一个IntentService类，我希望用一个警报让服务每X小时执行一次任务。

我检索警报并设置它，但服务每2秒执行一次任务，而不是每X小时执行一次;它永远不会停止：BroadcastReceiver始终触发Intent。

这是代码：

@Override
    protected void onHandleIntent(Intent intent) {
        int alarmType = AlarmManager.RTC_WAKEUP;
        username = intent.getStringExtra("username");
        //android.os.Debug.waitForDebugger();
        alarms = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        context = getApplicationContext();
        SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);
        serviceToStart = intent.getStringExtra("serviceToStart");

        if (serviceToStart.equals("calls")) {
            String CALLS_ALARM_ACTION = "ACTION_CALLS_LOGGING";
            Intent callsIntentToFire = new Intent(CALLS_ALARM_ACTION);
            callsIntentToFire.putExtra("serviceToStart", serviceToStart);
            callsAlarmIntent = PendingIntent.getBroadcast(context, 0, callsIntentToFire, 0);
            callsUpdatefrequency = toLong(Integer.parseInt(prefs.getString(Preferences.CALLS_FREQUENCY_PREF, "0")));
            long callsTimeToUpdate = SystemClock.elapsedRealtime() + callsUpdatefrequency;
            alarms.setRepeating(alarmType, callsTimeToUpdate, callsUpdatefrequency, callsAlarmIntent);
            dumpCallsLog();

最后一个方法（dumpCallsLog（））是更新远程数据库的方法。我有什么遗漏或代码中的错误吗？

这是我的BroadcastReceiver代码：

public class LoggingReceiver extends BroadcastReceiver {
    public static final String ACTION_CALLS_LOGGING = "ACTION_CALLS_LOGGING";

    @Override
    public void onReceive(Context context, Intent intent) {
        Intent startIntent = new Intent(context, LoggingService.class);
        String action = intent.getStringExtra("serviceToStart");
        startIntent.putExtra("serviceToStart", action);
        context.startService(startIntent);
    }
}

完成！我的坏：

String CALLS_ALARM_ACTION = "ACTION_CALLS_LOGGING";
                    Intent callsIntentToFire = new Intent(CALLS_ALARM_ACTION);

                    callsIntentToFire.putExtra("serviceToStart", "dumpCalls");
                    callsIntentToFire.putExtra("username", username);

                    callsAlarmIntent = PendingIntent.getBroadcast(context, 0, callsIntentToFire, 0);

                    callsTriggerAlarmTime = AlarmManager.ELAPSED_REALTIME_WAKEUP;

                    long callsAlarmInterval = 30000L;
                    // toLong(Integer.parseInt(prefs.getString(Preferences.CALLS_FREQUENCY_PREF,
                    // "86400000")));

                    alarms.setRepeating(alarmType, callsTriggerAlarmTime,
                            callsAlarmInterval, callsAlarmIntent);

AlarmManager启动服务无法正常工作
