FM收音机需要插入耳机作为天线，拔出耳机时要自动退出
1.首先添加提示字符串
mediatek/packages/apps/FMRadio/res/values/strings.xml
<!--TChip ZJ Add Below--><string name="toast_plugin_headphone_before_FM">The FM will close because you have been plug out the headphone</string><string name="toast_fm_enter_airplane_mode">The FM will close because you have been entered the airplane mode</string>
2.修改FMRadioService
mediatek/packages/apps/FMRadio/src/com/mediatek/FMRadio/FMRadioService.java
