How to transmit infrared by android phone for TV like power on or off?

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);

I already declared in manifest. it's not crashing but i don't know whether it's transmitted or not.After that i do not know how to know what it's going to transmit and whether it's transmit or not.so please tell me whether this is right code or not or how i check code is properly working or not by programming. thanks in advance.

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {

           Toast.makeText(MainActivity.this , "This device is not Support     infrared." , Toast.LENGTH_LONG).show();
        }
      }



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;
 }
}

I also set the permission in menifest file.

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