The place where the players are created is important. Proper application design can reduce the amount of bugs that are hard to find. The following tips may reduce MMAPI-related bugs in MIDlets:
Do not try to create players before the execution of the startApp() method of the MIDlet has begun. For example,
do not try to create player objects in the MIDlet constructor or static
sections. These are executed before the startApp() method of the MIDlet.
Problems will occur if you create players in the constructors of classes that have members of their object type in the MIDlet or which are further instantiated because of the MIDlet construction.
