如何通過Android手機傳輸紅外線，如電視開機或關機？

Question

int[] power= {123,339,23,54,23,14,23,16,21,14,21,16,21,14,23,16,21,16,21,14,23,53,23,15,22,16,21,54,23,14,23,16,21,16,21,54,23,54,23,53,23,54,23,14,23,54,23,14,23,54,22,54,23,16,21,16,21,14,23,14,23,16,21,16,21,54,23,54,23,15,22,15,22,14,23,14,23,14,23,14,23,53,23,54,23,14,23,14,23,16,21,54,23,14,23,16,21,14,23,16,21,14,23,16,21,14,23,53,23,53,23,54,23,54,23,2500}; 
ConsumerIrManager mCIR = (ConsumerIrManager) getSystemService(android.content.Context.CONSUMER_IR_SERVICE); 
    mCIR.transmit(47000, power); 

我已經在清單中聲明。它不會崩潰，但我不知道它是否傳輸或不傳播。之後我不知道如何知道它將傳輸什麼以及它是否傳輸或不傳輸。所以請告訴我這是不是正確的代碼，或者我是如何通過編程檢查代碼是否正常工作。 在此先感謝。

protected String hex2dec(String irData) { 
List<String> list = new ArrayList<String>(Arrays.asList(irData 
    .split(" "))); 
list.remove(0); // dummy 
int frequency = Integer.parseInt(list.remove(0), 16); // frequency 
list.remove(0); // seq1 
list.remove(0); // seq2 

for (int i = 0; i < list.size(); i++) { 
list.set(i, Integer.toString(Integer.parseInt(list.get(i), 16)*26)); 
} 

frequency = (int) (1000000/(frequency * 0.241246)); 
    list.add(0, Integer.toString(frequency)); 

irData = ""; 
for (String s : list) { 
irData += s + ","; 
} 
return irData; 
} 
} 

我還設置在menifest文件的權限。

<uses-permission android:name="android.permission.TRANSMIT_IR" 
android:required="false" />
