我正在使用警報(bào)管理器調(diào)用 REST API。但問題是當(dāng)用戶更改系統(tǒng)時(shí)鐘時(shí)間時(shí)它會(huì)立即觸發(fā)。必須在上午 9:00 準(zhǔn)確調(diào)用 REST API。假設(shè)用戶在上午 8:00 更改時(shí)鐘，并且鬧鐘在上午 10:00 觸發(fā)，因此會(huì)導(dǎo)致問題。我使用 PHP-MySQL 作為后端。你也可以說我的鬧鐘不必依賴于Android系統(tǒng)時(shí)間。它必須取決于印度標(biāo)準(zhǔn)時(shí)間。應(yīng)在上午 9:00 除外調(diào)用 REST API后端 PHPREST API 恰好在上午 9:00 調(diào)用。當(dāng)用戶更改系統(tǒng)時(shí)鐘時(shí)間時(shí)，警報(bào)管理器會(huì)立即觸發(fā)。設(shè)置報(bào)警方式   public static void setAlarm(Context context) {    Intent intent = new Intent(context, MyBroadcastReceiver.class);    PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 234324243, intent, 0);    AlarmManager alarmManager = (AlarmManager) context.getSystemService(ALARM_SERVICE);    Calendar calendar = Calendar.getInstance();    calendar.setTimeInMillis(System.currentTimeMillis());    calendar.set(Calendar.HOUR_OF_DAY, 9);    calendar.set(Calendar.MINUTE, 0);    calendar.set(Calendar.SECOND, 0);    if (calendar.before(Calendar.getInstance())) {        calendar.add(Calendar.DATE, 1);    }    alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);  }BroadcastReceiver.java      public class MyBroadcastReceiver extends BroadcastReceiver {      @Override      public void onReceive(Context context, Intent intent) {        if (isNetworkConnected(context)) {           doUpdate(context);        }      }    private void doUpdate(final Context context) {    class DoInsert extends AsyncTask<String, String, String> {        @Override        protected String doInBackground(String... strings) {            Retrofit retrofit = AppConfig.getRetrofit();            Api service = retrofit.create(Api.class);            Call<Response> call = service.doOperation();            call.enqueue(new Callback<Response>() {                @Override                public void onResponse(Call<Response> call, retrofit2.Response<Response> response) {                    Response response1 = response.body();                    Log.d("RESPONSE ======== ", response1.getMessage());                    return;                }
