System.TypeInitializationException: The type initializer for 'LightningDB.Native.NativeMethods'

[tl.sar...@gmail.com]

Hi,

I am new to SiaqoDB. I have installed trail version in my Xamarin Cross Platform project for Android Version. while creating the instance for SiaqoDB, I am getting the following error. 

"System.TypeInitializationException: The type initializer for 'LightningDB.Native.NativeMethods' threw an exception." 

I have added "siaqodb.dll" and "siaqodbportable.dll" as reference in my project. Please let me know how to fix this issue.

Advance Thanks.

The best way to solve this problem is to add Siaqodb from Nuget in all of your projects within the solution.

As per below comment, I installed SiaqoDB from Nuget. Still I am facing the same issue. Please suggest.

-What platform do you target: Xamarin(Android, iOS), UWP, .NET Core, .NET 4.5?

-Can you send us a repro project?

[tl.sar...@gmail.com]

I am choosing solution as Xamarin Cross Platform and targeting now Xamarin Android. Later I will concentrate on Xamarin iOS. Sorry I don't have repro project, I am directly working on project.

And on Android, what processor settings/target you have , ARMv7, ARM? and what is the min Android version? (A screenshot with the project settings would be great.)

Please find the screenshot for Android Target Version. I am new to Xamarin, where can I check the ARM settings? Please guide me.

It looks like in the current nuget package of Siaqodb (5.5.0.6) the 32bit Version of the LMDB native binaries are missing for Android (Xamarin).
If you build your app with target armeabi-v7a, the reccomended target for Xamarin Apps (source: https://developer.xamarin.com/guides/android/application_fundamentals/cpu_architectures/)
the file "liblmdb.so" is missing in the folder: lib/armeabi-v7a/ of the resulting apk.

You can't add them manually because for Android they should be included in the Siaqodb.dll and SiaqodbPortable.dll

See: "Xamarin.Android: LMDB native binaries are embedded into Siaqodb.dll so nothing should be done."
source: http://siaqodb.com/docs/Platform-specifics/

@Dotissi SRL: You should be able to fix that problem by building the libraries (Siaqodb.dll and SiaqodbPortable.dll) specificly for armeabi-v7a

I had this issue until I realized I needed to add SiaqoDB to my Android project--not just the PCL project where I was using it.
