Recently doing a APP, needs a little. Need to access the headphones force under the condition of using the receiver to vocalize (headphones inside out to make no noise can be).

The idea is:
1. Through the code directly forced open the receiver model;

2. The temporary code block headphones mode (equivalent to pull out the headphones);

Although thought, contemplating how also can not find the solution, a great god genuflect is begged.

Thank you thank you...
