电视开机关机等如何通过androidphone发射红外线？

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);

我已经在清单中声明了。它没有崩溃，但我不知道它是传输还是 not.After 我不知道如何知道它要传输什么以及它是传输还是 not.so 请告诉我这是正确的代码还是不是或我如何通过编程检查代码是否正常工作。提前致谢。

irData = "";

}

}

I also set the permission in menifest file.

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