Reading the error, it is easy to point out that the following line is causing the Verify
error
TagOptionSingleton.getInstance().setAndroid(true);
Could not find method org.jaudiotagger.tag.TagOptionSingleton.getInstance, referenced from method com.example.scrlltabs3.songManagerDialog$3.onClick
Googling the issue I came across the following stackoverflow question/answer that describes the same issue and offers a solution by replacing:
audioFile.commit();
with
AudioFileIO.write(audioFile)
See here the question and with above solution. If this resolved your issue then don't forget to give the answerer Paul Taylor in that answer an upvote.
java.lang.verifyError happens when JVM's bytecode verifier try to verify all the byte code before execution and fail when it finds inconsistencies and these inconsistencies can rise due to many factors such as
A detailed explanation about the VerifyError with examples can be found here.
See the examples in the above link which demonstrate how verify error is thrown by JVM.
