Crash when initializing a map

Issue Type

[X] Question
[X] Bug

Description and/or steps/code to reproduce the problem

I had a crash on a customer's phone on that line :
Configuration.getInstance().load(getApplicationContext(), PreferenceManager.getDefaultSharedPreferences(getApplicationContext()));

But it does work fine when I am testing on Galaxy S7, Nexus 5. Here is the Fabric's stacktrace :

Fatal Exception: java.lang.RuntimeException: Unable to start activity ComponentInfo{ ... }: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.String.startsWith(java.lang.String)' on a null object reference

I can see that the NPE happened in the load() method in DefaultConfigurationProvider.java.

In my project, this is the line where it crashs, located in the onCreate() of my Activity, before I inflate my map:
Configuration.getInstance().load(this, PreferenceManager.getDefaultSharedPreferences(this));

Environment

If it's a bug, version(s) of android this affects:

At least Sony Xperia Z3 (6.0.1) and One Plus 5 (8.1)

Version of osmdroid the issue relates to:

5.6.5

I can tell you that happened when a user did an update with an previous project without osmdroid

Can you post the full stacktrace? I suspect this is an issue in StorageUtils.
