在Echoprint系列--编译中编译了源码，这次将Echoprint移植到Android平台并测试识别歌曲功能。
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，所以参数不一样的，使用javah将Codegen.java生成头文件
zhangjiedeMacBook-Pro:java zhangjie$ javah -classpath . -jni cc.jwzhangjie.echoprintandroid.Codegen
在终端的当前目录会生成一个cc_jwzhangjie_echoprintandroid_Codegen.h
