在 lollipop 更新后，我试图让红外发射器在 HTC ONE m8 上工作。我正在尝试使用此处的 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，但该应用程序根本不传输信号。我没有收到任何错误，但红外发射器甚至没有打开。这是同一个项目，没有任何修改。为什么它不起作用？任何在 HTC 上使用红外线工作的人的帮助都是非常合适的。它可以让红外线在除 HTC 之外的所有设备上工作。
这是主类的代码，如果有帮助的话:
public class OneCIRActivity extends Activity {
private final static String TAG = "OneCIR";
private boolean running;
ConsumerIrManagerCompat mCIR;
Button btnLearn, btnSend, btnSendByIRManager, btnStart, btnStop;
TextView textView;

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_onecir);
btnStart = (Button)findViewById(R.id.buttonstart);
// btnStart.setOnClickListener(btnStartListener); //HTC optional (see onResume())
// 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);
btnSend.setOnClickListener(btnSendIRListener);
btnSend.setText("Send IR"); //BOTH
btnStop = (Button)findViewById(R.id.buttonstop);
// btnStop.setOnClickListener(btnStopListener); //HTC optional
// btnStop.setText("CIRControl.stop");
btnStop.setVisibility(View.GONE);
textView = (TextView)findViewById(R.id.textview1);
mCIR = ConsumerIrManagerCompat.createInstance(getApplicationContext());
mCIR.start(); //for HTC - noop otherwise (also see onResume()/onPause() )
mCIR.setTextView(textView); // to pass errors to UI
updateUI();
}

最佳答案
HtcConsumerIr 应用程序不适用于 Lollipop，因为如果您有 KitKat，它只会使用 HTC 库。 如果您打开 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);
}
为此:
if (hasPackage("com.htc.cirmodule", context)) {
return new ConsumerIrManagerHtc(context);
} else {
return new ConsumerIrManagerBase(context);
}
它会起作用。
我目前正在尝试让我的应用在升级到 Lollipop 后再次运行。在 KitKat 中一切正常，无需使用 HTC 库。 我还没有让它完全工作，但我已经让它传输了。似乎我们又回到了使用脉冲计数而不是持续时间。
