Android jAudioTagger Problem - Reading mp3 file - VerifyError

Question

Hi All,

I have the following error but cannot workout the problem, i am READING MP3 files and the below error seems to come as it tries to WRITE MP4 files.

AudioFile f = AudioFileIO.read(m_file.get(x));

Error comes after calling the above and passing the first MP3 file

Answer 1

An Android port is being put in place, the above error was due to some Swing libraries that aren't available in Android
