Question

Is there a length limit for navigation routes Saw an <https kotlinlang slack com archives CJLTWPH7S p1618453603379700|old thread> but seems to be about a different issue We re sending a form input as query input which can take up to 1000 characters The destination cannot be found if the argument is too long it seems

Ian Lake · Answer

There is no limit

Ian Lake · Answer

If your query input contains special characters you d need to `Uri encode` it

Yeah we do encode it Let me double check the value Edit I m seeing only percents and numbers Trying to binary search if there is a specific set of characters which breaks the navigation destination matching

allan.conda · Answer

Soo Turns out it s the same double decoding root cause that I raised for a different issue

Rafael Costa · Answer

let me guess some of your arguments are not mandatory arguments right Allan

Rafael Costa · Answer

I actually have opened a change in the Androix repo I was not sure if how exactly was the best way to open an issue with a suggestion fix so I did that sweat smile where I explain that non mandatory arguments are being decoded twice Your fix for now is probably to also encode twice all non mandatory arguments The mandatory arguments you must only encode once

Rafael Costa · Answer

btw < Ian Lake> I CC ed you in that Change

Rafael Costa · Answer

and sorry if there is a more correct way to do that sweat smile

I had raised it last month but for a different issue <https issuetracker google com issues 210711399|https issuetracker google com issues 210711399>

allan.conda · Answer

Yeah optional args the bug in the code is pretty clear Actually I don t encode twice because it will break once they fix it I manually do the decoding instead from the route which is also included as an argument

Rafael Costa · Answer

I see Yeah you could also just remove the second encode call just before updating the nav lib to the one with the fix That s what Im doing in my navigation library If you re curious <https github com raamcosta compose destinations|https github com raamcosta compose destinations>
