Script Error: ReferenceError: isAndroid is not ... no method 'startsWith'

[Jo Elegolo]

Hello!

Sorry, I do have a severe problem. Trying to use DroidScript on Samsung Tablet with Android 4.4.4 (API level: 19) using Cyanogenmod.

Error Dialog at (the end of? App screen seen in background) startup:

-------------------------------------------------------------------

Script Error

_________

Script Error: Object Uncaught ReferenceError:

isAndroid is not defined has no method

'startsWith'

Source: file://android_asset/DroidScript.js

Line: 1017

________________________________________

                      OK

--------------------------------------------------------------------

After 'OK' DroidScript terminates.

So far, problem popped up after having installed a lot of other Apps.

Reboot does not change problem state.

Deinstallation (all plugins as well) and Reinstallation of DroidScript does not change error state.

Any idea what I could do?

Addendum: Error did not occur before update to 1.78 - maybe API level 19 is no longer supported?

[Jo Elegolo]

Addendum 2: 1.76 works without this problem.

Thanks for the report. I'll look into this later today and I may contact you privately to test some things if I cannot reproduce the problem.

After frequently replacing the automatically reinstalled version 1.78 by 1.76, I once more came to the error (1.78 reinstalled again), but saw the error with a modified message:

Script Error

Script Error: Object agent = Mozilla/5.0 (Linux;

has no method 'startsWith'

Soure: file:///android_asset/DroidScript.js

Line:1017

(I hope, this manual copy of the error is all right)

 

Perhaps that could help finding the problem, which must be specific for my system, as no one else seems to run into it.

Meanwhile I also had problems with my favorite browser Firefox, which I had to replace by Google Chrome for now.

I have a workaround, don't hurry :)

I sent you a private email in reply on this thread on November 7. Did you receive it?

It's fixed in the next release.  Older phones don't fully support ES6 JavaScript features, so I've added the following polyfill to DS:-

if (!String.prototype.startsWith) {
    Object.defineProperty(String.prototype, 'startsWith', {
        value: function(search, rawPos) {
            var pos = rawPos > 0 ? rawPos|0 : 0;
            return this.substring(pos, pos + search.length) === search;
        }
    });
}

Hello

I have the same problem. Error at line 1017 in the doidscript.js file. How can I solve it or do I have to wait for the next version? And when will the new version be?

Thank you

LV

[Steve Garman]

There isn't really a practical way for you to fix it.

There will be a fix in the next telease but there is no date for that release yet.

The latest alpha 179a1b was issued before this issue was raised but a polyfill will be included in the next alpha.

If you want to know when the next alpha is available you could join the beta group.

Just email sup...@droidscript.org from the email address you use for this group explaining that you would like an invite to join the beta group.

Thank You very much, Dave!

Problem fix confirmed! DroidScript works again on my Samsung TAB4 with Android 4.4.

I have the same issue by using plugin BluetoothLE, but, hope that will be corrected with the next 'complete' DS version update. Am I right?

[Jo Elegolo]

To be onest, not just the identical issue, error tells:

Script Error: org.droidscript.plugins.BluetoothLE Source: file:///android_asset/app.js Line:1688

BluetoothLE plugin version is 1.05
