Question

我在某个时候建立了一个Android应用程序以控制我的空调，它曾经在Android 4.1中工作正常（我使用的是HTC M8手机），现在升级到5.0棒棒糖后它停止工作我附加了一个样本片段

没有调试错误，表示IR已传输。

PS：我已经模拟了所有连接的代码，

有人可以帮我把东西放在一起，或者我错过了什么吗？

Answer 1

在Android 4.4.3之前，模式的每个元素都是开/关脉冲的周期数。

对于Android 4.4.3及以上版本的每个元素，如果开/关脉冲的微秒数。

Answer 2

好的，所以最初API支持脉冲，我建立它现在它们支持持续时间，以微秒为单位，因为我的原始数据是比特我没有触及那个，而是在我的getter中我确实选择修改和传输因此公式代表duration = (1000000 / frequency) * pulse并传输持续时间不是脉冲的数组。

//To hold my codes for remote say on, off temp+, temp-, swing etc
public class TransmissionCodes{
    private int[] transmission; //will use to store and send transmssion
    private int frequency;//fed from my properties file
    private String countPattern; // Fed as string from my properties file

    //This modification in the getter did the trick
    private int[] getTransmission() {
        int pulses = 1000000/this.frequency;
        String[] countArray = this.countPattern.split(",");
        int[] anotherFix = new int[countArray.length];
        for (int i = 0; i < countArray.length; i++) {
            anotherFix[i] = Integer.parseInt(countArray[i]) * pulses;
        }
        return anotherFix;
    }
    //+getters +setters +constructor
}

//To hold all the TransmissionCodes objects
SparseArray<TransmissionCodes> sequence ;

//power on
sequence.put(0,     new TransmissionCodes(38000,    "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"));
//power off
sequence.put(1,     new TransmissionCodes(38000,    "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"));


//IR call in main Activity
findViewById(R.id.button).post(new Runnable() {
    public void run() {
        ConsumerIrManager mCIR = (ConsumerIrManager) getSystemService(android.content.Context.CONSUMER_IR_SERVICE);
        mCIR.transmit(sequence.getFrequency, sequence.getTransmission);
    }
});

但是我正在寻找可以应用于HTC的修复程序，因为此修复程序仅适用于具有IR的三星手机。也没有检查LG手机。但基于我的研究，三星和LG应该工作HTC在IR API上有一个顶峰。望着

在Android 4.4无法正常工作后，IR传输ConsumerIrManager类
