在Echoprint系列--编译中编译了源代码，这次将Echoprint移植到Android平台并測试识别歌曲功能。

一、编译库

1、环境准备

• Android NDK，我的是android-ndk-r10e
• 改动源代码，把src中的.cxx的文件重命名为.cpp。把src文件夹重命名为jni
• Boost源代码。在PC上编译的时候也安装boost的，我的时boost_1_58_0，复制到jni文件夹

2、编写编译配置文件

Notes about libcodegen:

Code generation takes a buffer of floating point PCM data sampled at 11025 Hz and mono.

Codegen * pCodegen = new Codegen(const float* pcm, uint numSamples, int start_offset);

pcm: a buffer of floats, mono, 11025 Hz
numSamples: the number of samples
start_offset: creates a hint to the server on where the sample is taken from in the original file if known

string code = pCodegen->getCodeString(); 
The code string is just a base64 encoding of a zlib compression of the original code string, which is a hex encoded series of ASCII numbers. See API/fp.py in echoprint-server for decoding help.

You only need to query for 20 seconds of audio to get a result.

native String codegen(float data[], int numSamples);

#include <string.h>
#include "cc_jwzhangjie_echoprintandroid_Codegen.h"
#include "Codegen.h"

JNIEXPORT jstring JNICALL Java_cc_jwzhangjie_echoprintandroid_Codegen_codegen
  (JNIEnv *env, jobject thiz, jfloatArray pcmData, jint numSamples){
       float *data = (float *)env->GetFloatArrayElements(pcmData, 0);
       Codegen c = Codegen(data, (unsigned int)numSamples, 0);
       const char *code = c.getCodeString().c_str();
       env->ReleaseFloatArrayElements(pcmData, data, 0);
       return env->NewStringUTF(code);
  }

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE     := echoprint-jni

LOCAL_SRC_FILES  := cc_jwzhangjie_echoprintandroid_Codegen.cpp 				    Codegen.cpp 				    Whitening.cpp 				    SubbandAnalysis.cpp 				    MatrixUtility.cpp 				    Fingerprint.cpp 				    Base64.cpp 				    AudioStreamInput.cpp 				    AudioBufferInput.cpp
					
LOCAL_LDLIBS     := -llog				    -lz					
					
LOCAL_C_INCLUDES := . 					./boost_1_58_0

LOCAL_CPPFLAGS   += -fexceptions

include $(BUILD_SHARED_LIBRARY)

APP_STL := gnustl_static
APP_ABI := armeabi armeabi-v7a

如今成功编译出libechoprint-jni.so文件

二、调用库

Codegen.java这个类用来调用so将ccm生成code

package cc.jwzhangjie.echoprintandroid;

/**
 * Created by zhangjie on 15/6/9.
 */
public class Codegen {

    private final float normalizingValue = Short.MAX_VALUE;

    native String codegen(float data[], int numSamples);

    static
    {
        System.loadLibrary("echoprint-jni");
    }

    /**
     * Invoke the echoprint native library and generate the fingerprint code.<br>
     * Echoprint REQUIRES PCM encoded audio with the following parameters:<br>
     * Frequency: 11025 khz<br>
     * Data: MONO - PCM enconded float array
     *
     * @param data PCM encoded data as floats [-1, 1]
     * @param numSamples number of PCM samples at 11025 KHz
     * @return The generated fingerprint as a compressed - base64 string.
     */
    public String generate(float data[], int numSamples)
    {
        return codegen(data, numSamples);
    }

    /**
     * Invoke the echoprint native library and generate the fingerprint code.<br>
     * Since echoprint requires the audio data to be an array of floats in the<br>
     * range [-1, 1] this method will normalize the data array transforming the<br>
     * 16 bit signed shorts into floats.
     *
     * @param data PCM encoded data as shorts
     * @param numSamples number of PCM samples at 11025 KHz
     * @return The generated fingerprint as a compressed - base64 string.
     */
    public String generate(short data[], int numSamples)
    {
        // echoprint expects data as floats, which is the native value for
        // core audio data, and I guess ffmpeg
        // Android records data as 16 bit shorts, so we need to normalize the
        // data before sending it to echoprint
        float normalizeAudioData[] = new float[numSamples];
        for (int i = 0; i < numSamples - 1; i++)
            normalizeAudioData[i] = data[i] / normalizingValue;

        return this.codegen(normalizeAudioData, numSamples);
    }
}
