[Kasun Kanchana]

I'm developing an image classification Android app, but each time I try to compile it, I get an error.

These are the libraries that I'm using.

I think this is related to the TensorFlowLite -Update. This wrapper uses Guava IO Library (guava-26.0-android.jar).

are there any solutions for this?

 

[Kasun Kanchana]

If I remove the TabStripViewPager library from libraries, then the app is compiled without any error.

What happens if you add this to the main module:

#ExcludedLib: guava-26.0-android.jar

I tried. Now I'm getting this error

Add these three lines:

#ExcludedLib: guava-26.0-android.jar
#AdditionalJar: com.google.guava:guava
#AdditionalJar: com.google.guava:listenablefuture

Confirm that it works and I'll update the library thread.

Yes. Now it's compiled without any issue, and the image classification is also working. Thank you.
