What do I use now that Handler() is deprecated?

How do I fix the deprecation warning in this code? Alternatively, are there any other options for doing this?

Handler().postDelayed({
    context?.let {
        //code
    }
}, 3000)
Solution

  • Only the parameterless constructor is deprecated, it is now preferred that you specify the Looper in the constructor via the Looper.getMainLooper() method.

    Use it for Java

    new Handler(Looper.getMainLooper()).postDelayed(new Runnable() {
    @Override
    public void run() {
        // Your Code
    }
}, 3000);

    Use it for Kotlin

    Handler(Looper.getMainLooper()).postDelayed({
    // Your Code
}, 3000)
