Mobile test: Optimize the original function, change the interface need to be compatible with the old and new version

training under the test line V1.0.1 (moon Angel V4.8.0), because in this version changed the logic of the course state change, from the original teacher click the upper and lower classes to update the status of the course, according to schedule time, the use of timers to update the status of the course, there has been a great change in logic.

And the interface, my teaching from the original three pages to reduce to two, as well as the corresponding number of angle index statistics, and many other situations. Originally did not consider the compatibility of the old version of the function, resulting in the modified interface does not correspond, resulting in the old part of the function called the modified interface, return parameter exceptions and other errors.

This update is not mandatory update, so the subsequent modification of the interface or new interface, compatible with the old version, to ensure that the old version of the normal operation, but my teaching angle number will appear in the results and the list of statistical results inconsistent, based on business needs and implementation, decided to take the new version of the subject.

　　Note that after the mobile end of the test, the original function is optimized, change the interface, need to be compatible with the old and new version.
