我正在应用程序中使用 Google Pay 实现 Braintree Drop-in UI，并且在选择 google pay 时开始出现错误，该对话框显示消息“意外的开发人员错误，请稍后再试”，以下是错误：

以下是我在 gradle 中添加的依赖项：

 def androidSupportVersion = "27.1.1"  
implementation fileTree(include: ['*.jar'], dir: 'libs')  
implementation "com.android.support:cardview-v7:$androidSupportVersion"   
implementation "com.android.support:recyclerview-v7:$androidSupportVersion"   
implementation "com.android.support:support-v4:$androidSupportVersion"   
implementation "com.android.support:design:$androidSupportVersion"   
implementation "com.android.support:design:$androidSupportVersion"   
implementation "com.google.android.gms:play-services-wallet:16.0.0"   
implementation "com.android.support:customtabs:$androidSupportVersion"   
implementation "com.android.support.constraint:constraint-layout:1.1.3"   
implementation 'com.braintreepayments.api:drop-in:3.+'

Braintree Google Pay 集成代码： 

GooglePaymentRequest googlePaymentRequest = new GooglePaymentRequest()
            .transactionInfo(TransactionInfo.newBuilder()
                    .setTotalPrice(priceString)
                    .setTotalPriceStatus(WalletConstants.TOTAL_PRICE_STATUS_FINAL)
                    .setCurrencyCode("GBP")
                    .build())
            .billingAddressRequired(true)
            .uiRequired(true);

java.lang.ClassNotFoundException：找不到类 “android.support.v7.app.AppCompatViewInflater”

您的build.gradle. 删除其中之一：

implementation "com.android.support:design:$androidSupportVersion"   
implementation "com.android.support:design:$androidSupportVersion"  // Remove this

更新：看起来像一个错误27.1.1。尝试更新到28.0.0：

def androidSupportVersion = "28.0.0"

查看Google Pay 疑难解答指南可能会有所帮助。

对我来说，这ClassNotFoundException只是一个警告。在注意到 Google 在故障排除页面上的建议后，潜在的错误出现在 logcat 中：

Note: The error only becomes visible in logcat after you've pressed OK to close the alert.

按 OK 后，我收到一条非常具体的错误消息，与我如何组装付款数据 JSON 请求有关。

确保将 appcompat 支持库添加为 build.gradle 文件中的依赖项。

dependencies {
    implementation 'com.google.android.gms:play-services-wallet:16.0.0'
    implementation 'com.android.support:appcompat-v7:$androidSupportVersion'
}
