Android Java: "cannot Resolve" In Postdelayed

I am using the first answer here to try to initiate a repeating task, updating a seekbar ('timeSlider') to show progress as an audio file plays. The repeating function is updateTi

Solution 1:

You could replace:

timeSliderHandler.postDelayed(updateTimeSlider, timeSliderInterval);

with:

timeSliderHandler.postDelayed(doUpdateTimeSlider, timeSliderInterval);

You forgot to write do in doUpdateTimeSlider.

Solution 2:

As you can see here : https://stackoverflow.com/a/41413191/4409113

It is : doUpdateTimeSlider

finalRunnabledoUpdateTimeSlider=newRunnable() {
     @Overridepublicvoidrun() {
         timeSliderHandler.postDelayed(doUpdateTimeSlider, timeSliderInterval);
         updateTimeSlider();
     }
 };

Which @ρяσѕρєя K said the same.

Update:

To fix that may not have been initialized you can follow these links:

variable r might not have been initialized

"Variable example might not have been initialized" in anonymous class

So:

finalRunnableetc=null;
    finalRunnabledoUpdateTimeSlider=newRunnable() {
        @Overridepublicvoidrun() {
            timeSliderHandler.postDelayed(etc, timeSliderInterval);
            updateTimeSlider();
        }
    };

This should work now!
