Answer 1

The poi library has dependancy clashes with multidex apk build. To fix these clashes:

1. Remove gradle reference to the dependancy or jar [as bellow].
2. Add this jar without clashing dependancies to /lib

3. Add the following line to module gradle:

   //    implementation 'org.apache.poi:poi-ooxml:3.17'
   

   implementation files('libs/poishadow-all.jar')

4. You can also right click the jar and choose add as library which will do this automatically

The jar was built from This Github repository
