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

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；在某些设备(例如 Android 5.x)中，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，用户通过将 VS2005 升级到 VS2008 来修复它。然而，我们在 Android 中运行它。

我也引用了以下帖子无济于事:

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

最佳答案

我按照后续步骤解决了上述问题

第 1 步:使用相同的 NDK 运行时 STLport_shared 或 gnuSTL_shared 构建 JNI 源代码和 Google Protobuf C++ 源代码，我们可以定义它在 Application.mk 文件中作为

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 获得更多关于 android NDK 运行时的信息。

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

include $(CLEAR_VARS)

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_LDLIBS += -lz
LOCAL_EXPORT_LDLIBS += -lz
LOCAL_EXPORT_CFLAGS := $(LOCAL_CFLAGS)
LOCAL_EXPORT_CPPFLAGS := $(LOCAL_CPPFLAGS)
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_C_INCLUDES)
include $(BUILD_SHARED_LIBRARY)

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

引用链接Android NDK Standalone toolchain

使用上述步骤可能会解决此问题。
