How to clear arguments in Fragment?
android, fragment
Solution
Make sure you are reading `getArguments()` in `onCreate()` method of the fragment. Once the fragment was created, when going back you souldn't pass trough `onCreate()`, so you shouldn't be able to read again the arguments.
If this still does not work, you could make use of a boolean flag and read the arguments only once.
Something like this:
if(!argumentsRead){
// read arguments
argumentsRead = true;
}
Problem
I have an `AudioPlayerFragment` to which I pass some url with setArguments(). If I have an `url` key in the `getArguments()` of my instance of `AudioPlayerFragment`, I start a service that plays the audio stream. If there was already a stream playing, I stop it and start it again with the new stream. If there is no arguments, I do nothing. My problem is that the arguments are kept with the instance, so when I get back to it, `getArguments()` returns the latest arguments set, if no new have been set. So after reading them, I try to set the arguments to null with ``` setArguments(null); ``` But I get ``` Java.lang.IllegalStateException: fragment already active ``` How can I clear the arguments then?
