4 years ago I was experimenting with this repo and here is what worked:
- Included jna.aar file in jna folder
- Modified project's build.gradle file (add "apply true" to the plugins)
- Modified app's build.gradle file (add import and update relevant entries as well as path in externalNativeBuild)
- Updated interfaces, tasks and MainActivity
- Removed jniLibs folder
- Removed TagOld.java file
- Modified CMakeLists.txt (remove all -fsanitize flags and add Android guard)
Here is what modifications look like:
Android guard, which allows it to bypass examples and tests but I am not sure if it is correct and whether it works properly in other platforms:
if(NOT CMAKE_SYSTEM_NAME STREQUAL "Android")
# add the examples and tests
all entries here
endif()Project's build.gradle file:
plugins { id 'org.ajoberstar.grgit' version '4.0.2' apply true }
App's build.gradle file:
import org.ajoberstar.grgit.Grgit
externalNativeBuild {
cmake {
path "$rootDir/app/src/main/cpp/libplctag/CMakeLists.txt"
version "3.10.2"
}
}
task checkoutLibplctagSource {
def libplctagFolderPath = "$rootDir/app/src/main/cpp/libplctag"
def libplctagFolder = new File(libplctagFolderPath)
// if it does not exist, then clone the repo.
if(!libplctagFolder.exists()) {
Grgit.clone(dir: libplctagFolder, uri: "https://github.com/libplctag/libplctag.git", refToCheckout: "release")
} else {
// if it does exist, do a pull.
def grgitInstance = Grgit.open(dir: libplctagFolder)
grgitInstance.pull()
}
}The above procedure does clone the "release" library but continuous connection to the Internet is required while working on the project in Android Studio since, whenever synced, it will throw an error if it cannot find github.com.
My solution was to clone the library, update the CMakeLists.txt file, comment out the above procedure and then switch networks for testing while working on the project.

The Tag.java file is a copy of the version in libplctag4j.
The solution should be to use libplctag4j directly either in the same manner as libplctag is used or by cloning/pulling the repo and then just using the single file. Ideally the entire libplctag4j repo could be used as is and a minimal JAR built with just the single Tag.class file in it.
