Protobuf android NDK

Question

我正在尝试使用android studio构建Protobuf2.6.1NDK，但我不知道如何将protobuf包含在gradle文件中。我也尝试过android.mk和eclipse中的任何一个，请帮助我。

    LOCAL_PATH := $(call my-dir)
    include $(CLEAR_VARS)

    LOCAL_MODULE    := libprotobuf

    LOCAL_SRC_FILES :=\
    src/google/protobuf/descriptor_database.cc \

    ifeq ($(TARGET_ARCH),x86)
    LOCAL_SRC_FILES := $(LOCAL_SRC_FILES) \
    src/google/protobuf/stubs/atomicops_internals_x86_gcc.cc

    endif

    LOCAL_CFLAGS := -D GOOGLE_PROTOBUF_NO_RTTI=1
    LOCAL_CPPFLAGS := -std=c++11
    LOCAL_C_INCLUDES = $(LOCAL_PATH)/src

    LOCAL_EXPORT_LDLIBS := -lz
    LOCAL_EXPORT_CFLAGS := $(LOCAL_CFLAGS)
    LOCAL_EXPORT_CPPFLAGS := $(LOCAL_CPPFLAGS)
    LOCAL_EXPORT_C_INCLUDES := $(LOCAL_C_INCLUDES)

    include $(BUILD_STATIC_LIBRARY)

Answer 1

我在我的项目中添加了新模块，并将其命名为Proto。这是我的分级文件：

apply plugin: 'protobuf'

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'ws.antonov.gradle.plugins:gradle-plugin-protobuf:0.9.1'
    }
}

dependencies {
    compile 'com.google.protobuf:protobuf-java:2.6.0'
}

protocPath = 'C:/Users/Paul/proto/protoc'
extractedProtosDir = "${project.buildDir.path}/extracted-protos"
generatedFileDir = "${projectDir}/src/main/java"
//protobufCodeGenPlugins = ['foo:./protoc-gen-foo', 'bar']

dependencies {
    // If you have your protos archived in a tar file, you can specify that as a dependency
    //   ... alternative archive types supported are: jar, tar, tar.gz, tar.bz2, zip
    protobuf files("src/main/protos/dungeon.proto")
    // Different configuration fileSets are supported
    //testProtobuf files("src/main/java")
}

然后在我的应用程序build.gradle中添加了编译项目(':proto')

最后，在我的设置中，gradle我有包括':app'、':proto'
