Android Question BLE2: cannot find symbol.

Hi,
I've tried to use a BeaconParser_B4A code for read beacons but when I compile the code I've this issue:

B4A version: 7.01
Parsing code. (0.01s)
Compiling code. (0.08s)
Compiling layouts code. (0.00s)
Organizing libraries. (0.00s)

Compiling generated Java code. Error
B4A line: 48
For Each b() As Byte In Starter.manager.GetReco
javac 1.8.0_131
src\beacons\sample\beaconparser.java:182: error: cannot find symbol
final anywheresoftware.b4a.BA.IterableList group24 = _starter._manager.GetRecordsFromAdvertisingData(_advertisingdata,_key);
^
symbol: method GetRecordsFromAdvertisingData(Map,int)
location: variable _manager of type BleManager2

BLE library is 1.35.

What is wrong in this code?

Thanks for your help.
