Problems with locating ArrayAdapter creation

Question

this is the result of the Logcat that I'm currently getting:

Is there a way to understand what ArrayAdapter is crashing? Unfortunately the project is really big, concurrent and I have no idea of which one is crashing (and debugger doesn't help a lot) :(

Any idea? Thanks!

The resource in ArrayAdapter.java:394 is null. This is because you try to call something that is not specified.

Looking at the source of the ArrayAdapter it seems to me that you didn't specify a correct textViewId or a wrong item layout. If you would update your question with the code where you initialize the adapter I could be more specific.

the problem is that I have a lot of ArrayAdapters and I don't know which one crashes.. is there a way to locate the chosen one? – Filnik Jan 20 '15 at 12:47
Not really you can narrow it down by just posting those of your current active activity/fragment – Dominic Jan 20 '15 at 13:05

In case anyone is interested, the problem was in a DialogFragment where the previous coder has let a "null" case as description... so the String array that goes inside the ArrayAdapter was like "[null]" causing the crash.

Resolving the default case with null into a more descriptive (and not null) message, solved the problem.
