Very poor performance during transitions on Android (3.0.9)

[Jickelsen]

I version 3 I am still getting so low performance during transitions that my app locks up and is eventually killed. I found a console.log in Reducers.js on line 119, regardless if dev mode is on or not. It seems it isn't great for Android performance, see #199. However, commenting this out does not seem to affect performance, and neither do any of the other proposed fixes from that issue.

This is in a list<-> detail view in a very simple example app, I even tried it with static data (so no network requests during transitions) and the problem is still there. The only thing I haven't tried yet is to delay rendering of the new view until the transition has completed. No other logging going on from what I can see.

Tested on a Moto G3.

It is just wrapper around new Navigation API. Check performance within React Native UIExplorer example for that API

[Jickelsen]

You're right, the animated nav example in UIExplorer is rather slow too, though it doesn't freeze up completely. The other examples in that same app run fine however. I'll see if it helps turning off animations, and hope things improve to the official release.

I am getting this too, eventually the app freezes completely and dies. I am having trouble working out what's causing it (I upgraded RNRF 3 with RN 0.22 so it's hard to tell)

@Jickelsen if you figure out a way around this please let me know!

I'm experiencing the same behaviour, Also when I fill a form the form refuse to loose focus, then the state freeze and the app crash. Tested with 3.1 and tcomb-form-native (also with react-native-stateless-form)

[thessem]

@delta-9 I am experiencing exactly the form focus issue too. Weird

@delta-9 Exactly same issue

[aksonov]

Guys, I don't understand why you are posting it here. The component is just WRAPPER and use new Navigation API, so please complain it here : https://github.com/ericvicenti/navigation-rfc or at react native github.

[sylvainbaronnet]

Sorry.

I think we should report it to the official RN repo since :

NavigationExperimental has recently been moved from here to the open source RN

[delta-9]

Sorry, I see that issue here so I reported here, I'll report it back to the RN repository

my problem
hi, I do not know if because of me or because of a malfunction of the plugin. i have this problems

1)in the router bar if i see a title, this is to bottom of bar and the bar is too big respect you example.

2. if i go to next page in the router bar i dont see the title and if i push the back button the app crashes

i install the last react native version in windows 10, i tested the app in the genymotion emulator with android 6.0, 5.1 and 4.4 but in same case the problems is the sames.
how do I fix this?

Weirdly enough, this doesn't seem to even be caused by navigating. Basically any component updating inside a scene results in memory being leaked and exponentially so, except when the scene is the very root scene - the problem does not manifest in that case.
