My code when using processing 3 works with the previous handler code: But for processing 4, it indicated handler deprecated. I am trying to fix the code but I could not fix it until not. Any solution to fix the code could be much appreciated. Below is the current structure of the code that I could not solve:

private final Handler mHandler = new Handler(Looper.getMainLooper()).postDelayed(new Runnable() {  
@Override  
public void handleMessage(Message msg)  
{  
switch (msg.what)  
{  
case MESSAGE\_WRITE:  
break;  
case MESSAGE\_READ:  
byte[] readBuf = (byte[]) msg.obj;  
readMessage = new String(readBuf, 0, msg.arg1);  
break;  
}  
}  
}, 1000);

Based on the information [here](https://developer.android.com/reference/android/os/Handler) on android official documentation. You can try -  
`new Handler(Looper.myLooper())`

All the best,
