Question

我希望在闹钟触发时通知用户。但它不会通知。我不知道为什么。我尝试了其他来源，但它根本没有帮助。

这是我的代码：

public class AlarmManagerBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        Intent intent3 = new Intent(context, ViewTasksActivity.class);
        PendingIntent pIntent3 = PendingIntent.getActivity(context, 0, intent3, PendingIntent.FLAG_UPDATE_CURRENT);

        //assigned a unique id to notifications
        Random random = new Random();
        int m = random.nextInt(9999 - 1000) + 1000;

        Notification mNotification = new Notification.Builder(context)
                .setContentTitle("Testing Notifications")
                .setContentText("")
                .setSubText("Complete the tasks under this activity.")
                .setSmallIcon(R.drawable.gsoicon)
                .setContentIntent(pIntent3)
                .setSound(soundUri)
                .build();

        NotificationManager notificationManager = (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);

        // If you want to hide the notification after it was selected, do the code below
        mNotification.flags |= Notification.FLAG_AUTO_CANCEL;

        notificationManager.notify(m, mNotification);


    }

我已将它放在清单文件中：

 <receiver android:name='com.goalsettingorganizer.AlarmManagerBroadcastReceiver'>
        </receiver>

设置闹钟代码：

public void SetAlarms(Context context, int goal_id)
    {
        dbhandler = new MyDBAdapter(context);

        AlarmManager am=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
        List<Activities> allActs = dbhandler.getAllActivitiesByGoal(goal_id);

        for (final Activities act : allActs) {

            //for alarm
            //Create an offset from the current time in which the alarm will go off.

            Calendar cal = Calendar.getInstance();
            cal.setTimeInMillis(System.currentTimeMillis());
            cal.set(Calendar.DATE, Integer.parseInt(act.getEDay()));  //1-31
            cal.set(Calendar.MONTH, Integer.parseInt(act.getEMonth()) - 1);  //first month is 0!!! January is zero!!!
            cal.set(Calendar.YEAR, Integer.parseInt(act.getEYear()));//year...

            cal.set(Calendar.HOUR_OF_DAY, act.getHour());
            cal.set(Calendar.MINUTE, act.getMinute());
            cal.set(Calendar.SECOND, act.getSecond());
            cal.set(Calendar.MILLISECOND, act.getMillisecond());

            //Create a new PendingIntent and add it to the AlarmManager
            Intent intent3 = new Intent(context, AlarmManagerBroadcastReceiver.class);
            intent3.putExtra("goalid", Integer.toString(goal_id));
            intent3.putExtra("activityId", Integer.toString(act.getActId()));
            intent3.putExtra("activityName", act.getActivityName());
            intent3.putExtra("show", "true");
            PendingIntent pendingIntent = PendingIntent.getActivity(context,
                    act.getActId(), intent3, PendingIntent.FLAG_CANCEL_CURRENT);

            if (Build.VERSION.SDK_INT >= 19)
                am.setExact(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);
            else
                am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);
        }

    }

我的错误：

我把getActivity（）放在PendingIntent而不是getBroadcast（）中。这就是OnReceive无法运作的原因。

删除清单上的android:process=":remote"。

OnReceive不适用于警报android
