Echoprint系列--Android编译与调用

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jniBoost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

打开源代码中的main.cpp，看到核心部分就是codegen_response_t *codegen_file(char* filename, int start_offset, int duration, int tag)

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.

打开Android Studio创建一个Android项目。新建一个文件名称为Codegen.java，在里面写入

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

这次在移动设备上识别的是通过麦克风录音。所以參数不一样的，使用javah将Codegen.java生成头文件zhangjiedeMacBook-Pro:java zhangjie$ javah -classpath . -jni cc.jwzhangjie.echoprintandroid.Codegen在终端的当前文件夹会生成一个cc_jwzhangjie_echoprintandroid_Codegen.h在libs同文件夹创建一个jni文件夹，把cc_jwzhangjie_echoprintandroid_Codegen.h拷贝进去，然后创建cc_jwzhangjie_echoprintandroid_Codegen.cpp文件，内容例如以下：

#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);
}

在jni文件夹以下创建Android.mk和Application.mk。内容分别例如以下：

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)

Application.mk

APP_STL := gnustl_static
APP_ABI := armeabi armeabi-v7a

把之前命名jni文件中面的内容复制到项目中的jni以下，在终端下输入：zhangjiedeMacBook-Pro:jni zhangjie$ ndk-build[armeabi] Compile++ thumb: echoprint-jni <= cc_jwzhangjie_echoprintandroid_Codegen.cpp[armeabi] Compile++ thumb: echoprint-jni <= Codegen.cpp[armeabi] Compile++ thumb: echoprint-jni <= Whitening.cpp[armeabi] Compile++ thumb: echoprint-jni <= SubbandAnalysis.cpp[armeabi] Compile++ thumb: echoprint-jni <= MatrixUtility.cpp[armeabi] Compile++ thumb: echoprint-jni <= Fingerprint.cpp[armeabi] Compile++ thumb: echoprint-jni <= Base64.cpp[armeabi] Compile++ thumb: echoprint-jni <= AudioStreamInput.cpp[armeabi] Compile++ thumb: echoprint-jni <= AudioBufferInput.cpp[armeabi] SharedLibrary : libechoprint-jni.so[armeabi] Install : libechoprint-jni.so => libs/armeabi/libechoprint-jni.so[armeabi-v7a] Compile++ thumb: echoprint-jni <= cc_jwzhangjie_echoprintandroid_Codegen.cpp[armeabi-v7a] Compile++ thumb: echoprint-jni <= Codegen.cpp[armeabi-v7a] Compile++ thumb: echoprint-jni <= Whitening.cpp[armeabi-v7a] Compile++ thumb: echoprint-jni <= SubbandAnalysis.cpp[armeabi-v7a] Compile++ thumb: echoprint-jni <= MatrixUtility.cpp[armeabi-v7a] Compile++ thumb: echoprint-jni <= Fingerprint.cpp[armeabi-v7a] Compile++ thumb: echoprint-jni <= Base64.cpp[armeabi-v7a] Compile++ thumb: echoprint-jni <= AudioStreamInput.cpp[armeabi-v7a] Compile++ thumb: echoprint-jni <= AudioBufferInput.cpp[armeabi-v7a] SharedLibrary : libechoprint-jni.so[armeabi-v7a] Install : libechoprint-jni.so => libs/armeabi-v7a/libechoprint-jni.so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);
}
}
