Android Question What is anywheresoftware.b4a.BA$SharedProcessBA

[Gary Milne]

I get this error calling DBUtils to do an InsertMap.

java.lang.NullPointerException: Attempt to read from field 'anywheresoftware.b4a.BA$SharedProcessBA anywheresoftware.b4a.BA.sharedProcessBA' on a null object reference

This is the line of code:

DBUtils.InsertMaps(Main.DB, "SK_SESSION_MASTER", MapList)

Even if I try to step into the DBUtils module it will crash with the above error. I've placed the call within a Try\Catch and it still crashes.

I've used this same code elsewhere and it works but in this one place it crashes.

Any ideas or pointers as I'm out.

Without seeing your code it is nearly impossible to give congrete advices.

Hello,
I have a supposed similar error, but only in 'Debug Legacy' mode,
see my post about it -> https://www.b4x.com/android/forum/threads/error-only-in-debug-legacy-mode.58006/

Have you tried in Release or Rapid Debug ?
And indeed without a sample of code or not enough details it's not easy to help.

Regards.

I'm using Rapid and did try Release with same result. I don't think it's the code per-se as I use identical code elsewhere to update a different table in the same database. Also, a Try\Catch structure does not catch it. Thanks for taking a look, I was hoping someone would be able to give me a clue about what the error meant.

Here is the context of the code but it seems like it is not a code issue. If I try and step into the DBUtils.InsertMaps Sub it crashes with the above error.
