SCROLL DOWN TO SEE THE ERROR MESSAGE
On occasion my app expects input from the user. When he does enter something, I use Toasts to display that the input was accepted.
And so far... this worked great! But eventually I noticed, when I started spamming the input button the app would freeze.
After some trial and error, I noticed, the problem was neither the button spamming nor the creation of Toasts.
So you can follow my conclusion, I am gonna list here the most important points. (On a side note: I am working in Kotlin and haven't tried other languages)
Spamming a button with the following onClickListener freezes the app
myButton.setOnClickListener {
Toast.makeText(this, "myText", Toast.LENGTH_SHORT).show()
}
At first I thought there might be a problem with my button, but in the end there was nothing wrong with it. (I am not gonna post code from the button, since you can use an auto-generated one)
I then came to the conclusion that the problem may come from the generation of Toasts. After all, according to the error message, there seems to be a buffer overflow.
So I tried creating only one toast and display that one.
class... {
val toast = Toast.makeText(this, "myText", Toast.LENGTH_SHORT)
override fun onCreate(savedInstanceState: Bundle?) {
...
myButton.setOnClickListener{
toast.show()
}
}
}
I still get the same error:

Now to the question: Did somebody else encounter this error and found a fix? My workaround so far is to disable the button spamming.
I also tried displaying Toasts in their own UI-Thread, but that didn't work. (The tip came from here: Toast is crashing Application, even inside thread)
Maybe this fix works for one of you, which means, I must have done a mistake.
Thanks for your help in advance!
