如何在 Android studio 上实现 Paypal 客户端支付?

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

我正在尝试在我的应用程序中添加 Paypal。但是,它抛出以下错误:

    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.

这是我的 gradle.properties:

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

这里build.gradle:

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

那么,这个库有什么问题??任何答案将不胜感激。

确保您的 gradle.properties 位于根项目中(或者更确切地说,您的 mavenUsernamemavenPassword 位于根项目的 gradle.properties 中)
