Question

I'm trying to build protobuf 2.6.1 NDK using android studio but I don't know how to include protobuf in gradle file also I have tried Android.mk and eclipse non of them working, please help me on this.

    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) \

    endif

    LOCAL_CFLAGS := -D GOOGLE_PROTOBUF_NO_RTTI=1

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

    include $(BUILD_STATIC_LIBRARY)

_"I have tried Android.mk and eclipse non of them working"_ Then you should include that Android.mk file in your question. It's impossible for anyone else to know what you might have done wrong simply by reading that "you've tried it". — Michael, Aug 26 '15 at 05:27
And what are the errors you're getting when trying to build with this makefile? — Michael, Aug 26 '15 at 11:15
@Michael I followed [this](http://stackoverflow.com/a/7155854/2624806) to get rid of it. But I'm getting **No rule to make target jni/src/google/protobuf/stubs/common.cc**. Any suggestion what I'm missing there! — CoDe, Sep 18 '15 at 09:40

I added new module to my project and named it proto. And here is my gradle file for it:

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")
}

Then in my app build.gradle I added compile project(':proto')

And finally in my settings.gradle I have include ':app', ':proto'

Hope it helps
