Question

很抱歉重新发布同样的问题，但我阅读了关于该问题的每一篇文章并完全按照他们的说法行事，但我无法解决问题。所以请阅读我的代码并告诉我下面的错误：

**安排闹钟：**

  public void progr(View v){

    Calendar calendar = Calendar.getInstance();

    //calendar.set(Calendar.DAY_OF_YEAR, 1);
    calendar.set(Calendar.HOUR_OF_DAY, 12); // For 1 PM or 2 PM
    calendar.set(Calendar.MINUTE, 36);
    calendar.set(Calendar.SECOND, 1);
    Long time = calendar.getTimeInMillis();//new GregorianCalendar().getTimeInMillis()+10*1000;


    Intent intentAlarm = new Intent(this, AlarmReciever.class);

    // create the object
    AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

    //set the alarm for particular time
    alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, time, 5000, PendingIntent.getBroadcast(this, 1, intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT));
    Toast.makeText(this, "Alarm Scheduled for Tommrrow", Toast.LENGTH_LONG).show();


    ComponentName receiver = new ComponentName(context, DeviceBootReceiver.class);
    PackageManager pm = context.getPackageManager();

    pm.setComponentEnabledSetting(receiver,
            PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
            PackageManager.DONT_KILL_APP);

}

Alarmreceiver扩展广播：

public class AlarmReciever extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{

     {

    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(Main.context)
                    .setLargeIcon(BitmapFactory.decodeResource(Main.context.getResources(), R.mipmap.ic_launcher))
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setContentTitle("Zall - Notification")
                    .setContentText("Veuillez cliquer pour epargner votre crédit.");

    Intent intentnot = new Intent(Main.context, Main.class);
    intentnot.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    PendingIntent pendingIntent = PendingIntent.getActivity(Main.context, 0, intentnot, 0);

    NotificationManager mNotificationManager =
            (NotificationManager) Main.context.getSystemService(Context.NOTIFICATION_SERVICE);

    int mId = 1234567890;

    Notification mNotification = mBuilder.build();
    mNotification.flags = Notification.FLAG_AUTO_CANCEL;
    mNotification.contentIntent = pendingIntent;
    mNotification.defaults = Notification.DEFAULT_ALL;
    mNotificationManager.notify(mId, mNotification);
    }
}

}

DeviceBootReceiver在设备启动后重新安排闹钟

public class DeviceBootReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
  {
        Calendar calendar = Calendar.getInstance();;

        //calendar.set(Calendar.DAY_OF_YEAR, 1);
        calendar.set(Calendar.HOUR_OF_DAY, 12); // For 1 PM or 2 PM
        calendar.set(Calendar.MINUTE, 27);
        calendar.set(Calendar.SECOND, 1);
        Long time = calendar.getTimeInMillis();//new GregorianCalendar().getTimeInMillis()+10*1000;

        // create an Intent and set the class which will execute when Alarm triggers, here we have
        // given AlarmReciever in the Intent, the onRecieve() method of this class will execute when
        // alarm triggers and
        //we will write the code to send SMS inside onRecieve() method pf Alarmreciever class
        Intent intentAlarm = new Intent(Main.context, AlarmReciever.class);

        // create the object
        AlarmManager alarmManager = (AlarmManager) Main.context.getSystemService(Context.ALARM_SERVICE);

        //set the alarm for particular time
        alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP,time,AlarmManager.INTERVAL_DAY, PendingIntent.getBroadcast(Main.context, 1, intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT));
        Toast.makeText(Main.context, "Alarm Scheduled", Toast.LENGTH_LONG).show();
    }
}

}

Answer 1

.DeviceBootReceiver的接收器应该如下所示

<receiver android:name=".DeviceBootReceiver" android:enabled="true" android:exported="true">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED"/>
    </intent-filter>
</receiver> code here

您需要允许接收方从应用程序之外的内容接收消息。 Read this for more information
