Clicking link on web container always force close the app

Question

I am using jasonette to create a webview / iframe / web container to load my website into native app (android). The website loaded beautifully, but somehow it always crashed when i tried to click any link in the website.

Here my code snippet to load the website

{
"$jason": {
    "body": {
      "background": {
        "type": "html",
        "url": "https://stackoverflow.com/",
        "action": {
          "type": "$default"
        }
      }
    }
  }
}

what is not correct about it? and is there a way to debug error in web container?

edit: when clicking any link, on logcat shows this message: W/JasonParser: processTask : java.lang.NullPointerException: Attempt to invoke virtual method 'com.eclipsesource.v8.V8Locker com.eclipsesource.v8.V8.getLocker()' on a null object reference

then it crashed

Can you attach your phone to the computer and try getting the output of `adb logcat`? — gkpln3, Oct 16 '19 at 07:09
it giving this on pressing link: W/JasonParser: processTask : java.lang.NullPointerException: Attempt to invoke virtual method 'com.eclipsesource.v8.V8Locker com.eclipsesource.v8.V8.getLocker()' on a null object reference — baycisk, Oct 16 '19 at 07:11
For some reason, the error shows up only in Android Studio's debug mode. Generating an APK and installing that works perfectly. Thanks :) — Anas Mehar, Oct 16 '19 at 07:18

Seems like this guy was having the same issue as you: https://github.com/jasonelle/jasonelle/issues/22

found the issue. for some reason, the error shows up only in Android Studio's debug mode. Generating an APK and installing that works perfectly. Thanks :)

Try installing a release version of the APK to the phone and check if it works for you.

Jasonelle does not allow website links, buttons and forms to functions in the app. Every page or link is in a .json file. you will have to create the destination pages is jsonelle json pages. i dont recommend using Jsonelle for webcontainer instead look into webview android.

you can also add

  <category android:name="android.intent.category.BROWSABLE"></category>

to you AndroidManifest.xml

how to route to another page in jasonelle

        {  
           "type" : "label",
            "text": "click here",
            "style": {
              "color": "black"
            },
            "url": "https://google.com/page.json"
          }
