Question

AlarmManager alarmManager=(AlarmManager) getSystemService(ALARM_SERVICE);

        Intent alarmIntent=new Intent(context,UpdateTables.class);

        PendingIntent pendingIntent=PendingIntent.getBroadcast(context,0,alarmIntent,PendingIntent.FLAG_UPDATE_CURRENT);

        alarmManager.cancel(pendingIntent);

        Calendar alarmStartTime = Calendar.getInstance();

        alarmStartTime.setTimeInMillis(System.currentTimeMillis());

        //midnight
        alarmStartTime.set(Calendar.HOUR_OF_DAY, 19);
        alarmStartTime.set(Calendar.MINUTE, 18);
        alarmStartTime.set(Calendar.SECOND, 0);

        if(Calendar.getInstance().getTimeInMillis()>alarmStartTime.getTimeInMillis())
        {
            alarmStartTime.add(Calendar.DATE,1);
        }

        Log.i("TIME IS ",Long.toString(alarmStartTime.getTimeInMillis()));


        System.out.println("Updating table time "+alarmStartTime);
        System.out.println("Time in millseconds "+alarmStartTime.getTimeInMillis());


        alarmManager.setInexactRepeating(AlarmManager.RTC,alarmStartTime.getTimeInMillis(),AlarmManager.INTERVAL_DAY,pendingIntent);

        Log.d("Alarm","Set for midnight");

此警报正在触发其他接收者，即UpdateTables.java（这是有效的）

现在在UpdateTables.java中，它也创建了警报并将意图传递给另一个接收者。但是接收者没有收到意图。

 //show notification for the test ans follow up
        ArrayList<Action> notificationData=dbHelper.fetchTestAndFollowUpTime();


        for (int actionitem=0;actionitem<notificationData.size();actionitem++){

            Action actionItem=notificationData.get(actionitem);
            long hourRemainingCompeleteTask=TimeUnit.MILLISECONDS.toHours(actionItem.getActionEndDate()-Calendar.getInstance().getTimeInMillis());

            System.out.println("Action is "+actionItem.getAction_name());
            System.out.println("test time is "+actionItem.getActionEndDate());
            System.out.println("Current time "+Calendar.getInstance().getTimeInMillis());
            System.out.println("Hour remaining "+hourRemainingCompeleteTask);

            if (Long.valueOf(hourRemainingCompeleteTask).compareTo(24L)<0){
                //means remaining time is less than 24 hr.
                setAlarmToCallNotificationService(context,actionitem+alarmLastRequestCode+5,actionItem.getAction_name(),actionItem.getCatagory());
            }else {
                //in the else.
                setAlarmToCallNotificationService(context,actionitem+alarmLastRequestCode+5,actionItem.getAction_name(),actionItem.getCatagory());
            }
        }



 private static void init(Context ctx){
        if (alarmManager==null)
            alarmManager=(AlarmManager) ctx.getSystemService(ctx.ALARM_SERVICE);
    }
@SuppressLint("NewApi")
    private void setAlarmToCallNotificationService(Context context, int request_code, String notificationText, String notificationTitle) {
            init(context);

        Log.i("Inside notification,","Yes");

        Intent intent = new Intent(context, notificationService.class);
        intent.putExtra("Notification_title",notificationTitle);
        intent.putExtra("Notification_text",notificationText);


        //hit the notification At the 8.00 in the morning
        Calendar notificationCalendar=Calendar.getInstance();
        notificationCalendar.set(Calendar.HOUR_OF_DAY,11);
        notificationCalendar.set(Calendar.MINUTE,55);
        notificationCalendar.set(Calendar.SECOND,0);

        Long time=notificationCalendar.getTimeInMillis();

        System.out.println("NOTIFICATION Time is "+notificationCalendar.get(Calendar.HOUR_OF_DAY)+" "+notificationCalendar.get(Calendar.MINUTE));
        Log.i("Target",time.toString());

        //final int _id = (int) System.currentTimeMillis();
        PendingIntent pendingIntent = PendingIntent.getBroadcast(context, request_code, intent, PendingIntent.FLAG_ONE_SHOT);

        int currentapiVersion = android.os.Build.VERSION.SDK_INT;
        if (currentapiVersion < android.os.Build.VERSION_CODES.KITKAT){
            alarmManager.set(AlarmManager.RTC_WAKEUP, time, pendingIntent);
        } else {
            if (currentapiVersion < android.os.Build.VERSION_CODES.M) {
                alarmManager.setExact(AlarmManager.RTC_WAKEUP, time, pendingIntent);
            } else {
                alarmManager.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, time, pendingIntent);
            }
        }

        //AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
        //alarmManager.set(AlarmManager.RTC_WAKEUP, time, pendingIntent);

    }

但问题是，updateTables.java接收器没有触发notificationService接收器

public class notificationService extends BroadcastReceiver {

    public static String TAG="notificationService";
    @Override
    public void onReceive(Context context, Intent intent) {

        String notificatioTitle=intent.getExtras().getString("Notification_title");
        String notificationMsg=intent.getExtras().getString("Notification_text");

        Log.i(TAG,"Notification title "+notificatioTitle);
        Log.i(TAG,"Notification msg "+notificationMsg);

        NotificationCompat.Builder notification=new NotificationCompat.Builder(context)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentTitle(notificatioTitle)
                .setContentText(notificationMsg);

        NotificationManager mNotificationManager =(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        mNotificationManager.notify(0,notification.build());
    }


}

清单文件

<receiver android:name=".UpdateTables"
            android:enabled="true"
            android:exported="true">

            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>

        </receiver>

            android:enabled="true">

我根据这里给出的答案更改了代码，但仍然没有响起警报。

要确保您的活动正在调用，请使用以下方法：

private static AlarmManager am;
    private static void init(Context ctx){
        if (am == null)
            am = (AlarmManager) ctx.getSystemService(Activity.ALARM_SERVICE);
    }
    @SuppressLint("NewApi")
    public static void startbyalarmWake(Context ctx, long nexttim) {
        init(ctx);

        Intent intent = new Intent(ctx,BRWake.class);

        PendingIntent pi = PendingIntent.getBroadcast(ctx, SOMEID, intent, PendingIntent.FLAG_CANCEL_CURRENT);

        int currentapiVersion = android.os.Build.VERSION.SDK_INT;
        if (currentapiVersion < android.os.Build.VERSION_CODES.KITKAT){
            am.set(AlarmManager.RTC_WAKEUP, nexttime, pi);
        } else {
            if (currentapiVersion < android.os.Build.VERSION_CODES.M) {
                am.setExact(AlarmManager.RTC_WAKEUP, nexttime, pi);
            } else {
                am.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, nexttime, pi);
            }
        }
    }

警报未在Android
