I used this code for samsung tv of power on , volume up and down but it's not worked for me.so want to know i missed any thing or i am doing any thing wrong please suggest me.
power.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
irSend(v);
}
});
volup.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
irSend(v);
}
});
voldown.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
irSend(v);
}
});
irData = new SparseArray<String>();
irData.put(R.id.voldown,
hex2dec("0000 006d 0022 0003 00a9 00a8 0015 003f 0015 003f 0015 003f 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 003f 0015 003f 0015 003f 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 003f 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0040 0015 0015 0015 003f 0015 003f 0015 003f 0015 003f 0015 003f 0015 003f 0015 0702 00a9 00a8 0015 0015 0015 0e6e"));

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" />
<uses-feature android:name="android.hardware.consumerir" />
I used for only 19 and up version.when we click on Text power then infrared light was burning.
