android根据音乐路径获取音乐时长，采样率等

git路径为：https://github.com/zhangliangming/HPAudio

Gradle
1.root build.gradle

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

2.app build.gradle

dependencies { 
	compile 'com.github.zhangliangming:HPAudio:v2.4' 
}

混淆注意
-dontwarn javax.** -dontwarn java.awt.** -keep class org.jaudiotagger.** { ; } -keep class davaguine.jmac.* { ; } -keep class com.wavpack.* { ; } -keep class com.zlm.hp.audio.* { *; }

具体使用如下：

//获取时长
public static long getMusicDuration(String path){
        try{
            File file = new File(path);
            AudioFileReader audioFileReader = AudioUtil.getAudioFileReaderByFilePath(path);
            if(audioFileReader != null){
                TrackInfo trackInfo = audioFileReader.read(file);
                if(trackInfo != null){
                    return trackInfo.getDuration();
                }
            }
        }catch (Exception ex){
            ex.printStackTrace();
        }
        return 0;
    }
