智能手机安卓版c语言发出声音程序代码?

以下是智能手机安卓版使用c语言编写发出声音的程序代码示例：

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <fcntl.h>
#include <sys/ioctl.h>
#include <linux/soundcard.h>

void play_sound(char *file_path){
int dsp;
int format = AFMT_S16_LE;
int channels = 1;
int rate = 44100;
int buffer_size = 4096;

char *buffer = (char *) malloc(buffer_size);

dsp = open(file_path, O_RDONLY);
if(dsp < 0){
perror("Error opening file");
return;
}

ioctl(dsp, SNDCTL_DSP_SETFMT, &format);
ioctl(dsp, SNDCTL_DSP_CHANNELS, &channels);
ioctl(dsp, SNDCTL_DSP_SPEED, &rate);

while(read(dsp, buffer, buffer_size) > 0){
write(dsp, buffer, buffer_size);
}

close(dsp);
free(buffer);
}

int main(int argc, char *argv[]){
play_sound("/system/media/audio/ringtones/Basic_Bell.ogg"); // 例如播放当前系统默认提示音。
return 0;
}
