Hi

Hi,

I am having some issue with my Delphi code in android. I am trying to save some changes to the SQLite database from my app. I have created record object for my tables and have a generic datamanager for handling all database calls. The issue I am facing is if any exception is raised within the datamanager object then android hangs and doesn't even show me the error message. I have given below snippet of my datamanager code and also two sets of code one which works properly and the other which causes the issue. 

The error is raised by the validate procedure, which validates the data integrity and raises an exception if there are any inconsistencies.

Code snippet from the datamanager for saving the record to the database.
function TData_Manager.Save_Record(const ARec: T): Boolean;
begin
  { start a new transaction }
  _ConMgr.Start_Transaction;
  try
    { Validate changes before saving }
    FClass_Map.Validate(ARec);
    { Save changes to database including any detail items }
    FClass_Map.Save_ToDatabase(ARec);
    { Commit Changes }
    _ConMgr.Commit_Transaction;
    Result := True;
  except
    on e: Exception
    do begin
       { Rollback changes }
       _ConMgr.Rollback_Transaction;
       raise;
    end;
  end;
end;

ERROR CODE
**************************************
The following code doesn't even show me the message, but when run in debug mode it gives me segmentation error
function Save_Changes: Boolean;
begin
  try
    Result := FData_Manager.Save_Record(FData);
  except
    on e: Exception
    do begin
       Showmessage(e.message);
       Result := False;
    end;
  end;
end;
**************************************

WORKING CODE
**************************************
The following code works fine and gives me a proper error message and android doesn't hangs.
function Save_Changes: Boolean;
begin
  try
    if FData.Validate
    then Result := FData_Manager.Save_Record(FData);
  except
    on e: Exception
    do begin
       Showmessage(e.message);
       Result := False;
    end;
  end;
end;

Can anyone suggest me a solution for this. I am not sure why an error raised in a generic class gives a segmentation error in android. 

Thanks
