Onsen UI v2.0.0-rc.18 with Vanilla JS - ons-navigator doesn't work in Android 4.4.2 and older


  • I love this framework, it is framework agnostic and has beautiful UI. Recently I updated Onsen UI in my app to v2.0.0-rc.18, then I tested it in older Android version (4.2.2 and 4.4.2), the result is page navigation did not work.
    I also tested in Android 4.4.4 & 5.1.1, and they doesn’t have this issue.
    Reverting to v2.0.0-rc.17 and the navigation works good on those Android versions.

    @frosdqy Can you post your navigation code? Also, when are you calling it? Do you have any errors in the console or warnings? I have run several apps with Vanilla and did not experience this issue going from 17+. If I had to guess, it is going to be a DOM attachment issue or something else that is inhibiting the call to the navigator pushPage.

    Edit: The most important part is that the Android version should not have an issue as all Android’s support webkit / webview. The JS doesn’t change that so we have something else going on that is specific to that platform.

  • I use Onsen UI Navigation template in my app. I also tested with a new project using the template without major modifications (just changing the referenced js and css files to v2.0.0-rc.18 and changing toolbar text), the result is same (navigation is not working). When I click on a list item, nothing happens. Below is the used code:

    index.html

    Sorry, I don’t have any error message as I didn’t debug it. I just installed the apk on real devices (Samsung Galaxy Note II with Android 4.4.2 and another tablet with Android 4.4.0) and MEmu emulator (Android 4.2.2).

    @frosdqy Can you try the below code just to check some things? In the script tags, change rc18 to rc17 if it doesn’t work.

  • @munsterlander Tested your code with two devices (Android 5.1.1 and Android 4.4.0). It works on Android 5.1.1, but not working on Android 4.4.0. The error from Android 4.4.0: Uncaught TypeError: Cannot call method ‘removeEventListener’ of undefined
    File: https://cdn.rawgit.com/OnsenUI/OnsenUI-dist/2.0.0-rc.18/js/onsenui.js
    Line Number: 20438

    Also tested changing the RawGit links from rc.18 to rc.17, and it works on Android 4.4.0.

    @frosdqy Awesome! That is progress. The only downside, 2,362 additions, 1,730 deletions from RC.17 to RC.18. Maybe someone from the team will recognize what the change may be.

  • @frosdqy Have you tried using Crosswalk? That generally fixes device specific glitches like this.

    I think I know why this happens and have added a simple sanity check to fix the error that will be released with the next version.

  • @argelius Awesome!
    And will definitely try the plugin, thanks.
