Out Put:
Creating a New Project
- First, we will create a new Android Studio Project.
Adding Jar File
- Now download the mantra.mfs100.jar. We need to add this file in our project dependencies.
- So first on the project explorer select Project.
- Then inside app/lib paste the mantra.mfs100.jar that we downloaded.
- Then add dependency in your build.gradle.
implementation files('libs/mantra.mfs100.jar')
Adding jniLibs Folder
- · jniLibs.jar
- · Download jinLibs.jar file And then Extract.
- · Put jniLibs folder src/main/
mantra.mfs100.jar
·
mantra.mfs100.jar it is inside
the lib folder app/lib/
build.gradle
