java - "debug as"与导出的 APK 有何不同

Question

没有 lint 标记。通过 eclipse 插入计算机的每个设备进行调试时，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，它“不幸停止”。调试运行与编译的 apk 文件的主要区别是什么？当作为调试运行时，实时支付服务在项目中再次运行良好。此项目中没有对 SHA1 差异敏感的 API key (已签名的 apk 与调试)。

以下是我从 apk 安装的应用程序的报告中可以看到的一些情况:

在 Debug模式下，当我按下结帐按钮时它工作正常，但这是 logcat 中的内容，也许有人可以看到一些东西:

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、优化和混淆您的代码。结果是一个更小的 .apk 文件，但更多很难进行逆向工程。”

我没有包括:

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