由于三星设备非常糟糕，我转而使用 GenyMotion 作为 Android 模拟器。但是，在我拥有的三星 Note 上运行的代码在模拟器上因 NoClassDefFoundError 而崩溃。

我也尝试过不同的版本，它并没有真正帮助，事实上，PEMParser 显然在 1.47 中甚至不可用。代码如下：

   private final String csrPEM = "-----BEGIN CERTIFICATE REQUEST-----\n"

而且我也得到了VerifyError ...

   }

所以我真的无法判断这是否是模拟的 Google Nexus One、GenyMotion 或我的代码出现的错误。NoClassDefFound 和 VerifyError 都令人痛苦，我不知道如何追踪它.. :/

免责声明：我为 Genymotion 工作

这不是模拟器问题，而是 Android 问题。旧的 Android 版本（Gingerbread 现在已经 4 岁了）附带了非常古老的 BouncyCastle 实现。见（https://code.google.com/p/android/issues/detail?id=3280）

您的模拟器实际上是在警告您，您的代码可能无法在2.3.7 的 Android 设备上运行。

一种解决方案是在您的应用程序中发布最新的 BouncyCastle 实现。但是你会遇到冲突，因为它的包名与手机上的包名相同。为避免这种情况，您可以使用 SpongyCastle，一个最新的 BouncyCastle，但重命名以避免包名冲突。见http://rtyley.github.io/spongycastle/

我只是将 spongycastle 的依赖项添加到我的 gradle 构建文件中，修复了导入以使用 SpongyCastle，并且您的代码在 Genymotion Nexus One 上完美运行。

compile 'com.madgag.spongycastle:core:1.50.0.0'
compile 'com.madgag.spongycastle:prov:1.50.0.0'
compile 'com.madgag.spongycastle:pkix:1.50.0.0'
