Question

没有lint标记。在通过eclipse插入我的计算机的每台设备进行调试时，paypal sdk组件工作正常。当我将项目导出为APK时，当我到达应用程序的paypal部分时，“不幸停止”。调试运行与编译的apk文件的主要区别是什么？在作为调试运行时，实时支付服务再次在项目中正常工作。没有API密钥对此项目中的SHA1差异敏感（签名的apk与调试）。

以下是我从apk中安装的应用报告中看到的一些内容：

在调试模式下，当我按下结帐按钮时它工作正常，但这里是logcat中的内容，也许有人可以看到：

Answer 1

根据developer.android的说法，“ProGuard工具通过删除未使用的代码并使用语义模糊的名称重命名类，字段和方法来缩小，优化和混淆代码。结果是更小的.apk文件更多难以逆向工程。“

我未能包括：

 @proguard-paypal.cnf marker in the proguard-project.txt

“调试为”与导出APK有什么区别？
