How can I implement Paypal client side payment on Android studio?-CodePudding

I am trying to add Paypal inside my application. However, it throws me the following error:

    org.gradle.api.GradleScriptException: A problem occurred evaluating root project 'myFirstApp'.
Caused by: groovy.lang.MissingPropertyException: Could not get unknown property 'mavenUsername' for Credentials [username: null] of type org.gradle.internal.credentials.DefaultPasswordCredentials_Decorated.

Here is my gradle.properties:

android.useAndroidX=true
# Automatically convert third-party libraries to use AndroidX
mavenUsername=paypal_sgerritz
mavenPassword=AKCp8jQ8tAahqpT5JjZ4FRP2mW7GMoFZ674kGqHmupTesKeAY2G8NcmPKLuTxTGkKjDLRzDUQ

And build.gradle here:

allprojects {
    repositories {
        google()
        jcenter()
        mavenCentral()
        maven {
            url "https://jitpack.io"
        }
        maven {
            url  "https://cardinalcommerceprod.jfrog.io/artifactory/android"
            credentials {
                username mavenUsername
                password mavenPassword
            }
        }
    }
}

So, what is wrong with this library?? Any answer will be appreciated.

Make sure that your gradle.properties is located in the root project (or rather, that your mavenUsername and mavenPassword are in the root project's gradle.properties)
