protobuf版本为3.0.0。在某些设备(比如Android 6)中，这个问题总是会发生；而在一些设备(比如Android5.x)中，当应用程序被放到后台模式时，就会出现这个问题。

我调用以下方法：

bool ParseFromString(const string& data);

这可能在内部称为bool ParseFromArray(const void* data, int size)。堆栈跟踪：

显然，如箭头所示，它在google::protobuf::internal::WireFormatLite::ReadBytes(...)崩溃。这个问题已经在这条线中讨论过了，用户通过将VS2005升级到VS2008来修复这个问题。然而，我们在Android中运行这一功能。

我亦曾提及以下职位，但均告无效：

任何详细的帮助都是非常感谢的，因为我在用Android构建原型库方面还是新手。

我通过下面的步骤解决了上面的问题

步骤1:使用相同的NDK运行时stlport_shared或gnustl_shared，构建JNI源代码和Google C++源代码，我们可以在Application.mk文件中将其定义为

APP_STL := gnustl_shared

我使用gnustl-static构建了我的JNI源代码，这引起了问题。如果您在构建Google源代码时使用不同的运行时，可能会出现问题。您可以在Android CPP支持指南上获得有关android运行时的更多信息。

步骤2:确保您的JNI代码和共享库(libprotobuf.so)引用相同版本的Google库。它可能会在不同的android版本中导致未定义的行为。

您可以从Google Protobuf Git Repo下载最新的源代码

您可以遵循Android平台外部原型链接的构建步骤，或者为了简单起见，可以使用下面的"Andoid.mk“文件
