I downloaded and tried to start your project, getting this error:

android.database.sqlite.SQLiteException: table tbl_Messagesdata has 8 columns but 6 values were supplied (Sqlite code 1): , while compiling: INSERT INTO tbl_Messagesdata VALUES ('NULL', '1', '0001','Makumbi','0782911364','Good moring sula'), (OS error - 2:No such file or directory)

You know what it means (number of table fields and data in your query don't match).

Please, correct and attach it again (use the menu File - Export As Zip)

There are some wrong queries.

Use these as example:

B4X:

        oSQL.ExecNonQuery2("INSERT INTO tbl_Messagesdata VALUES (?,?,?,?,?,?,?,?)", Array(Null, DateTime.Now, "0001", "Makumbi", "0782911364", "Good moring sula", "IOFlag1", "INFlag1"))
        oSQL.ExecNonQuery2("INSERT INTO tbl_Messagesdata VALUES (?,?,?,?,?,?,?,?)", Array(Null, DateTime.Now, "0001", "Makumbi", "0782911364", "Arrivederci Roma", "IOFlag2", "INFlag2"))
        oSQL.ExecNonQuery2("INSERT INTO tbl_Messagesdata VALUES (?,?,?,?,?,?,?,?)", Array(Null, DateTime.Now, "0002", "Sula", "0782911555", "Good bye sula", "IOFlag3", "INFlag3"))
        oSQL.ExecNonQuery2("INSERT INTO tbl_Messagesdata VALUES (?,?,?,?,?,?,?,?)", Array(Null, DateTime.Now, "0002", "Sula", "0782911555", "Good morning sula", "IOFlag4", "INFlag4"))

Note: 8 question marks, 8 values.

Please don't consider the insert of queries I disregarded them only consider the creation of the two tables because in the second attachment I disabled them I remained with only the create table and it works

No, it works on your device because you already have the db in the internal directory.

hope this 3rd attachment is ok thank you for your precious time

i have also modifeied your query to have these fields as

B4X:

oSQL.ExecNonQuery2("INSERT INTO tbl_Messagesdata VALUES (?,?,?,?,?,?,?,?,?)", Array(Null, DateTime.Now, "0001", "Makumbi",  "Good moring sula", "IOFlag1", "INFlag1","0782911364","Father"))
      oSQL.ExecNonQuery2("INSERT INTO tbl_Messagesdata VALUES (?,?,?,?,?,?,?,?,?)", Array(Null, DateTime.Now, "0001", "Makumbi", "Arrivederci Roma", "IOFlag2", "INFlag2", "0782911364","Father"))
      oSQL.ExecNonQuery2("INSERT INTO tbl_Messagesdata VALUES (?,?,?,?,?,?,?,?,?)", Array(Null, DateTime.Now, "0002", "Sula", "Good bye sula", "IOFlag3", "INFlag3","0782911555","Mother"))

ONE error was inside the Add_Conversation routine, which should (and does) return a panel (the clv element) which is then added to the clv but you add the panel itself within this routine and then again when the routine ends and returns the panel (see from line 249 of Add_Conversation).

There is another wrong query (number of fields and values).

I have eliminated a Sleep; if you want to use this, the routine that contains it (LoadMessages) must complete its work before the project continues, which means calling it differently: https://www.b4x.com/android/forum/threads/b4x-resumable-subs-sleep-wait-for.78601/#content
