Toast is crashing Application, even inside thread
android, toast
Solution
You need to use runOnUiThread
Something like
runOnUiThread(new Runnable() {
public void run()
{
Toast.makeText(ctx, toast, Toast.LENGTH_SHORT).show();
}
});
`Toast` is a `UI` element so it needs to run on the `UI Thread`, not a background `Thread`.
However, if this is all you are using it for then you don't need a separate `Thread` just to show a `Toast`. If you can explain the context of how you are using it then maybe we can help with a better way. Also, if you are inside of your `Activity` then you don't need a variable for `Context`. You can use `ActivityName.this` instead to access the `Activity Context`
Problem
I have an onClick event in my android app that triggers the following code but it keeps crashing my app. I put it in a thread only because i read that that's supposed to prevent crashing. Also ctx refers to the Activity's context (it's a variable I created in the activity set equal to this. I've read and tried several things. Any help would be awesome. Thanks! ``` Thread toastThread = new Thread() { public void run() { Toast alertFailure = Toast.makeText(ctx, "Login Failed", Toast.LENGTH_LONG); alertFailure.show(); } }; toastThread.start(); ```
