Android Question Crash Report - java.lang.NullPointerException (main._process_globals)

[aaronk]

Hello,

I got a crash report in my Google Play Developer console and it says the following and I think it's all related to my Process_Globals sub..

java.lang.NullPointerException
in my.app.here.main._process_globals

    Dim main_title As Label
    Dim loaded As String = "0"
End Sub

In my Activity1 Globals I have for some reason added 'Dim Panel1 As Panel' there twice.
Could this be the thing stuffing up my app ?

I also thought I wasn't using 'Initialize' in the Globals and thought I was doing that in the Activity_Create sub but looks like I am not, so could this also stuff up the app and the reason why its creating this crash report.

The thing I like to know as well, why does my app work fine on my 4 Android devices, but on some other devices this crash happens ? (maybe android devices are all different in a way?)

Anyone know why my app happens to crash based on the above?
(I don't want to upload my project to the forum)

 

[Erel]

Is the code compiled in obfuscation mode? Can you open the generated Java source code (main.java) and post line number 1242 (and a few lines before and after)?

 

[aaronk]

Hi Erel,

Its complied in 'Release (obfuscated)'.

Here is the code from main.java that you wanted to see..
(I opened the file in Notepad++ and took a screenshot for you)

Let me know if you need anything else.

 

[Erel]

You have probably changed the code since this error. Can you post the Java code under _process_globals? The line numbers are not important.

 

[aaronk]

This is the code from main.java

The Java code I am posting (from the other post and this post) is the latest code and would of been the code that has been submitted to Google Play.
I have done some changes but the code posted has not been affected as I have copyied this Java code from a backup before I made the changes which hasn't been uploaded to Google Play yet.

There are some parts below I have edited with the word 'REMOVED' below that I have removed as I don't think the PublicKey or my domain name is required here.. (just in case we have some sticky beaks )

[Erel]

I don't see anything that can raise a NullPointerException here.

The relevant error is:
Caused by: java.lang.NullPointerException
at my.app.here.main._process_globals(main.java:1242)

The code must have changed as line 1242 is not part of _process_globals.

 

[aaronk]

I will just re-submit the new update and See if the same error happens again or not.

Thanks heaps for your help.

Make sure to save a copy of the 'src' folder.
