我最近将我的 Song Scrapbook 应用程序更新到了最新版本,并确保更新了该应用程序使用的所有第三方 API。一个这样的第三方工具是 PayPal Android SDK,我用它来通过我的应用程序获利,因为我生活在一个目前不支持 Google Wallet Merchant 服务的国家 - 这意味着我不能在应用程序内或一次性使用 Play Store我的应用程序中的购买系统。

但是,在我的应用程序中(通过 mavenCentral)将 PayPal SDK 更新到最新版本后,每次我想执行 PayPal 交易时,我都会在 Android Studio(版本:1.5.1)中收到以下错误:

我知道这个问题不是由我测试应用程序的设备引起的 - 因为我已经在两个非常不同的设备(Samsung Grand Neo 和 Cubot X15)上测试了这个应用程序,并且两个设备都产生了类似的错误。我尝试在谷歌上搜索问题以尝试解决问题,但经过数小时的搜索没有找到解决方案。

任何帮助将不胜感激。西尔苏尔。

所以我花了大约 5 个小时来解决这个问题 - 我通过逐步消除问题的可能原因来实现这一点。

原来真正的问题是我急于尝试更新应用程序。原因是 PayPal SDK 2.13.3 版本在“proguard-rules.pro”文件中有一个新规则,该规则非常重要:

规则如下:

    # This is added for okhttp 3.1.2 bug fix as shown at https://github.com/square/okhttp/issues/2323
    -keepclassmembers class * implements javax.net.ssl.SSLSocketFactory {
         private javax.net.ssl.SSLSocketFactory delegate;
    }

这可以防止 Gradle 的缩小(混淆)过程从 PayPal SDK 中导致安全层套接字工厂出现问题的先前错误修复中删除重要代码。所以是的 - 这就是修复:更新后的应用程序现在可以完美运行(正如需要)。

经验教训:确保你的“proguard-rules”完全符合他们的设想!

Over & Out,SilSur。
