Updating SKMaps from 2.5.0 to 2.5.1

I have a problem due to updating SKMaps from version 2.5.0 to version 2.5.1. Something doesn’t seem to be right with the native .so library. I always have this error:

11-24 10:34:04.922 7463-7884/de.mypackage A/libc: Fatal signal 7 (SIGBUS) at 0x00000017 (code=1), thread 7884 (e.mypackage) 

And after that I get this warning (But this is also displayed in log on app start!!!):

I am testing the app on armv7 platform. I pulled a new .so file by pulling a new SKMaps.zip with gradle task installSKMaps.

My build.gradle is configured as it is shown here:

Adding the SDK to the project using Gradle

But the update process is described in a more detailed way over here:

SDK Update Procedure (2.X to 2.Y)

Do I need to walk through all the steps in this description? So do I need the last step called There are 2 possibilities to perform an update by overwriting(1) or replacing(2)

Do I need to add this checkForUpdate() method into the source code as described in

2) Delete 2.X resources and keep only the 2.Y resources ?

At first I don't need any automation of the update process within the app. I first just want to update SKMaps in my app manually.

The 11-24 10:34:04.922 7463-7884/de.mypackage A/libc: Fatal signal 7 (SIGBUS) at 0x00000017 (code=1), thread 7884 (e.mypackage) can have multiple sources and has be investigated in a larger context (Android version, hardware config, OpenGL version, code flow, etc.)

As for the SDK update procedure:

• in the project: you need to update all the SKMaps specific resources (.so files, .jar, the SKMaps.zip)
• if you modified the content of the SKMap.zip then you need to make sure that your new SKMaps.zip combines your changes with the ones made by the new version
• at runtime, if you need to make sure that the new zip is properly unpacked and old resources replaced (if updating an already existing app) - that the purpose of the runtime procedure described at http://developer.skobbler.de/getting-started/android#sec028)
