Answer 1

try this code its working for Friday Alarm and similarly you can set for Saturday First you have to register your alarm Receiver and alarm time

public static void SetAlarmForFriday(Context mContext) {
        try {

            Calendar calendar = Calendar.getInstance();
            calendar.set(Calendar.DAY_OF_WEEK, Calendar.FRIDAY);
            System.out.println("Date " + calendar.getTime());

            int year = calendar.get(Calendar.YEAR);
            int month = calendar.get(Calendar.MONTH) + 1;
            int day = calendar.get(Calendar.DAY_OF_MONTH);

            String DateToConvert = day + "," + month + "," + year + " 10:10 AM";
            Date date = new SimpleDateFormat("dd,MM,yyyy hh:mm a", Locale.ENGLISH).parse(DateToConvert);

            Intent intent = new Intent(mContext, AlarmReceiver.class);
            intent.setAction("setYourActionHere");
            PendingIntent pendingIntent = PendingIntent.getBroadcast(mContext.getApplicationContext(), 234324243, intent, 0);
            AlarmManager alarmManager = (AlarmManager) mContext.getSystemService(mContext.ALARM_SERVICE);

            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, date.getTime(), AlarmManager.INTERVAL_DAY, pendingIntent);

        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }

Make Receiver Class

public class AlarmReceiver extends BroadcastReceiver {
    public AlarmReceiver() {
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO: This method is called when the BroadcastReceiver is receiving
        // an Intent broadcast.


    }

}

Register your Broadcast receiver in manifest file under Application tag

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