The method of introducing aar package in Android project

1. The method of introducing the aar package into the Android project

When I use the sdk of Gaode map, I choose to import the aar package, and then import it according to the online tutorial. But I kept reporting errors, and I was very confused.

here is the tutorial

1. Add in the outer layer of android{} in build.gradle

repositories {
    flatDir {
        dirs 'libs'
    }
}

2. Add the aar package to the libs folder of the project
3. Add it in dependencies

  implementation(name:'名称', ext:'aar')

However, in fact this method seems to be "outdated", now there is no need to add repositories {flatDir {dirs 'libs'}}

At this time, the way to introduce the aar package is simpler, only two steps are required

1. Copy the aar file to the libs folder;

2. Add in the dependencies of build.gradle 

implementation(fileTree("libs"))；

2. Android import jar package

As for how Android imports jar packages

1. First download the required jar package

2. Copy the jar package to the app->libs directory under the project (if the libs directory does not exist, create a new one)

3. Right-click the jar package, select add as library, a pop-up window, click OK to successfully import the jar package
