how to add jar/folder to project

[john bean]

Hi i am trying to add a external library to my project but cant seem to get it to work the library is

https://github.com/anandBrose/AmplitudeGraphView-Android

but cant get my project to recodnise it and cant figure wht i am doing wrong i have in gradle

implementation fileTree(dir: 'libs', include: '*.jar')

and have both the folder and the folder converted in jar in lib folder of my project but cant seem to use it and have no idea why it wont work
i have allso trued this library by adding
implementation 'com.chibde:audiovisualizer:2.2.0'
whic the gradle synced ok but it is not available in my project it has been so long since i have used an external library if anyone could point out my stupidity i would be greatful thanks

There is following article Git repos as Gradle dependencies which "recicpes" I did not tried out.

Following usage for Github source code usage is in section "Gradle source dependencies" and I filled in the fully-qualified package you mentioned:

dependencies {    implementation 'com.chibde:audiovisualizer:2.2.0' } sourceControl {    gitRepository('https://github.com/gradle/native-samples-cpp-library.git') {        producesModule('com.chibde:audiovisualizer)    } }

Other possibilities described in this article are:

using Github code as Git submodule

using external service 'Jitpack' that compiles the github module into an binary package
This method uses https://jitpack.io and I don't know whether it works with Android code

As I read it, the basic requirements are the same as for Maven projects with Gradle apparently using your lMaven repository services to resolve dependencies.

So if the JAR in question is a project that you build, then you'd need to build it wuth a "mvn install" (or Gardle equivalent) to build the JAR and post it to your local Maven repository cache. If the JAR is only available in binary form, you'd have to manually catalog it into the Maven repo, which can be done using Maven (here again, there may be a Gradle native equivalent I don't know about).

If the JAR is shared between multiple members of a team, then a site-local Maven repository server such as Nexus can help with that.
