I had a problem with alarm clock in my application and I decided to use AsyncStorage on Android side, then I use the code below and I could get all values from AsyncStorage and generate all alarms that was registered in my application's AsyncStorage.

SQLiteDatabase readableDatabase = null;
        readableDatabase = ReactDatabaseSupplier.getInstance(this.reactContext).getReadableDatabase();
        Cursor catalystLocalStorage = readableDatabase.query("catalystLocalStorage", null, null, null, null, null, null);
        try {
            List listaAlarmes = new ArrayList<>();
            if (catalystLocalStorage.moveToFirst()) {

                do {
                    //Ex: key: 01082019_0800
                    //value: [{executionDate: 2019-08-01T08:00}]
                    String key = catalystLocalStorage.getString(0);
                    String json = catalystLocalStorage.getString(1);

                    if (dados.length == 3) {
                        ...generate my alarms with key and json
                    }

                } while (catalystLocalStorage.moveToNext());

            }//2_31082019_0900 - [{"idPrescricaoMedicamento":35,"nomeMedicamento":"VITAMINA"}]

        } finally {
            if (catalystLocalStorage != null) {
                catalystLocalStorage.close();
            }

            if (readableDatabase != null) {
                readableDatabase.close();
            }
        }
