Google protobuf 在解析字符串数据时在 Android 中崩溃

Question

protobuf版本为3.0.0。在某些设备中（比如 Android 6），这个问题总是会发生；在某些设备中（比如 Android 5.x），当应用程序进入后台模式时会发生此问题。

我正在调用以下方法：

bool ParseFromString(const string& data);

这可能在内部调用 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(...) 处崩溃。此问题已在 this thread 中讨论过，其中用户通过将 VS2005 升级到 VS2008 来修复它。不过我们是运行这个在Android.

我也参考了以下帖子无济于事：

Android application crashes because of protobuf
Crash when parsing protobuf message containing a string using C++ and Android NDK
zeromq with protobuf segmentation fault while parsing in c++
Generated Protobuf code crashes application

感谢任何详细的帮助，因为我是使用 Android 构建 protobuf 库的新手。

Answer 1

我按照后续步骤解决了上述问题

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

APP_STL := gnustl_shared

我正在使用 gnustl-static 构建导致问题的 JNI 源代码。如果您在构建 Google Protobuf 源代码时使用不同的运行时，则可能会出现问题。您可以在 Android CPP support guide

获得有关 android NDK 运行时的更多信息

第 2 步： 确保您的 JNI 代码和共享库 (libprotobuf.so) 引用相同版本的 Google Protobuf 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

您可以按照 Android Platform external protobuf link 中的构建步骤进行操作，或者为简单起见，可以使用下面的 "Andoid.mk" 文件

LOCAL_CFLAGS := -D GOOGLE_PROTOBUF_NO_RTTI=1
LOCAL_CPPFLAGS := -std=c++11
LOCAL_C_INCLUDES = $(LOCAL_PATH)/android 
LOCAL_C_INCLUDES += ${ANDROID_NDK}/sources/cxx-stl/gnu-libstdc++/4.8/include

LOCAL_EXPORT_CFLAGS := $(LOCAL_CFLAGS)
LOCAL_EXPORT_CPPFLAGS := $(LOCAL_CPPFLAGS)
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_C_INCLUDES)

第 3 步： 您需要将波纹管标志添加到 Android.mk

LOCAL_CFLAGS += $(cf_includes) -DGOOGLE_PROTOBUF_NO_RTTI

参照linkAndroid NDK Standalone toolchain

使用上述步骤可能会解决此问题。
