if (mIrManager != null) {//Check whether the device has an infrared emitter.if (mIrManager.hasIrEmitter()) {//do something//Query the infrared transmitter's supported carrier frequenciesCarrierFrequencyRange[] frequencyRanges = mIrManager.getCarrierFrequencies();if (frequencyRanges != null) {for (CarrierFrequencyRange frequency : frequencyRanges) {frequencyRange += String.format("%1$d ~ %2$d \n",frequency.getMinFrequency(), frequency.getMaxFrequency());//do something}}}} 3.transmit
//This method is synchronous; when it returns the pattern has been transmitted. Only patterns shorter than 2 seconds will be transmitted.manager.transmit(frequency, pattern);
