It makes it possible to port and reproduce FlMML to Android. You can also open MML from URL. See CodePlex (Archive) for FlMML. https://archive.codeplex.com/?p=flmml Depending on the complexity of the MML and the performance of the terminal when reproducing MML from the beginning Although it may set for a while, it will be played as it is after waiting for the end of processing. Also, it may be that the application fails with an error. In that case, I would appreciate it if you can report as it is.
