Android : NDK : Superpowered Open failed: ENOENT (No such file or directory) Error

Hello I am trying to play audio.wav from internal storage using Superpowered::AdvancedAudioPlayer but NDK always through the Open failed: ENOENT (No such file or directory) exception. Code:

//-----------------Java---------------------------------------------------------------------------------

 String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/MyFolder/";
        String myfile = path + "filename" + ".mp3";



if (samplerateString == null) samplerateString = "48000";
        if (buffersizeString == null) buffersizeString = "480";
         samplerate = Integer.parseInt(samplerateString);
         buffersize = Integer.parseInt(buffersizeString);

//-----------------Cpp------------------------------------------------------------------------------------

SoundEffects1(samplerate,     // sampling rate
                        buffersize,     // buffer size
                        myfile,        // path to .apk package
                        fileAoffset,    // offset (start) of file A in the APK
                        fileAlength,    // length of file A
                        fileBoffset,    // offset (start) of file B in the APK
                        fileBlength,     // length of file B
                        myfile,
                        myfile
            );
