System.DllNotFoundException: '/data/data/com.companyname.pos.apphost/files/.__override__/runtimes/android-x64/native/libpdfium.so'

[hosamyousof]

I'm testing PDFtoImage.Conversion.ToImage() in .NET MAUI project that targets windows and android. It works fine in windows platform but throws an exception in android:

System.DllNotFoundException: '/data/data/com.companyname.pos.apphost/files/.override/runtimes/android-x64/native/libpdfium.so'

I'm testing on Android Emulator: Android 12.0 - API 31

I installed PDFtoImage v2.1.2

Can you please help me solve this issue.

Best regards,

Hi @hosamyousof,

what is the TargetFramework of this .NET MAUI project? Both net6.0-android21.0 and MonoAndroid 1.0 should include the needed Android binaries.

If it's just net6.0 (or newer) you must add those two missing NuGet packages on your own:

• https://www.nuget.org/packages/bblanchon.PDFium.Android/
• https://www.nuget.org/packages/SkiaSharp.NativeAssets.Android/

Hi @sungaila,

The target framework is net6.0-android.

How does the bin folder look like? Is there runtimes/android-x64/native/libpdfium.so copied to the output folder? Or is there a libpdfium.so in the root folder of the output?

[hosamyousof]

I think you mean the target framework should be: net6.0-android31.0 or later not net6.0-android21.0 Like mentioned in this warning:

I changed the target framework to net6.0-android31.0 and tried but I'm getting the same exception.

Regarding the bin folder: It looks like this

I tested .NET MAUI with Android and found the code for loading the libpdfium.so was not working.

Could you please give PDFtoImage 2.1.3 a try?

I appreciate your instance response @sungaila

I've updated the library to 2.1.3 and It's working fine.

Thank you.
