Android Question Why i am getting this error and how to fix it

[Mehrzad238]

I have a receiver for a Timer, and it works, but while that receiver is active, I get a two-line error for every Tick the timer makes. why?

Error creating activity intent: Attempt to read from field 'java.lang.String anywheresoftware.b4a.BA.className' on a null object reference in method 'java.lang.Class anywheresoftware.b4a.keywords.Common.getComponentClass(anywheresoftware.b4a.BA, java.lang.Object, boolean)'
Error getting service class: Attempt to read from field 'java.lang.String anywheresoftware.b4a.BA.className' on a null object reference in method 'java.lang.Class anywheresoftware.b4a.keywords.Common.getComponentClass(anywheresoftware.b4a.BA, java.lang.Object, boolean)'

When I disable the timer, it stops

So first of all, what is this, and why am I getting this error?
Second, how can I fix it?

Here is my info, and the project is B4Xpages.

The thread title should be informative.

Not enough information here to help you.

The thread title should be informative.

Next time, but I explained in the context: "I have a receiver for a Timer, and it works, but while that receiver is active, I get a two-line error for every Tick the timer makes."
If that is not enough, when I get home, I will upload the whole project to see for yourself

Here is my info

If the errors occur for every tick the timer makes, then the first place to look would be the timer tick event handler sub.

Without seeing that code, it is hard to say why you're getting the error and how to fix it.

Whole project is good if this is a small project. In most cases it is better to start with what you think is the relevant code.
