棒棒糖更新后，我正在尝试使红外发射器在HTC ONE m8上工作。我正在尝试使用在此处找到的HTC Sense IR SDK（addon-htc_ir_api-htc-19）：http://www.htcdev.com/devcenter/opensense-sdk/htc-ir-api我导入示例项目（HTCConsumerIR）并在我的HTC设备上运行该应用程序，而该应用程序只是不发送信号。我没有收到任何错误消息，但红外发射器甚至没有打开。这是同一项目，完全没有任何修改。为什么不起作用？ HTC的红外工作人员提供的任何帮助将非常适合。它可以使红外线在HTC以外的所有设备上工作。
这是主类的代码，如果有帮助的话：

// btnStart.setText("CIRControl.start");
btnStart.setVisibility(View.GONE);
btnLearn = (Button)findViewById(R.id.buttonlearn);
btnLearn.setOnClickListener(btnLearnListener);
btnLearn.setText("Learn IR"); //HTC
btnSend = (Button)findViewById(R.id.buttonsend);

btnStop = (Button)findViewById(R.id.buttonstop);
// btnStop.setOnClickListener(btnStopListener); //HTC optional

btnStop.setVisibility(View.GONE);

最佳答案
HtcConsumerIr应用程序不适用于Lollipop，因为只有在您拥有KitKat的情况下，它才会使用HTC库。
如果打开ConsumerIrManagerCompat.java并更改此行：
if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.KITKAT
&& hasPackage("com.htc.cirmodule", context)) {
return new ConsumerIrManagerHtc(context);
} else {
return new ConsumerIrManagerBase(context);
}
对此：
if (hasPackage("com.htc.cirmodule", context)) {
return new ConsumerIrManagerHtc(context);
} else {
return new ConsumerIrManagerBase(context);
}
它会工作。
我目前正在尝试升级到Lollipop后使我的应用程序再次运行。在KitKat上一切正常，无需使用HTC库。
我还没有完全正常运行，但是正在传输。似乎我们又回到使用脉冲计数而不是持续时间了。
