There will be an option in the next release (May) to overwrite the previous toast message, allowing for shorter toasts for second based countdowns etc.
I tried the loop trick, it works even though you can see the pop-up disappearing and reappearing. You say it works without doing that, is there something I'm missing? Maybe it depends by the android version or vendor UI?Toast durations are fixed, but a neat trick is if you want it to appear longer then you can just call it multiple times and it should remain on screen longer (without dissapearing and re-appearing). For example if you add it in a loop that runs 10 times, it will appear for 10 times as long.
