Ionic won't build

Question

I am fairly new to Ionic and android.

When trying to build my Ionic android app I get an error message.

:compileDebugJavaC:\Temp\Projekt\test\platforms\android\src\org\apache\cordova\filetransfer\FileTransfer.java:692: error: cannot find symbol
        if (!isLocalTransfer && !Config.isUrlWhiteListed(source)) {
                                       ^
  symbol:   method isUrlWhiteListed(String)
  location: class Config

Does anyone have an idea how to fix this? Thanks in advance!

Make sure that you have the android platform installed: `ionic platform add android` — kuzyn, Dec 13 '15 at 13:51

You're getting an error: cannot find symbol at compilation time. This error message was vastly discussed on this question.

Usually this means that you've misspelled some method name, or it doesn't exist at all.

In your specific case, the problem is on this method: Config.isUrlWhiteListed().

Check if it's spelled correctly, if the cases are correct (e.g. Url or URL), and if the method you're trying to invoke does really exists, because if you're following a tutorial it might have been removed on some release.

EDIT: As @kuzyn said on the comments, you'll also have to check if you have everything correctly installed on your machine (ionic, cordova, etc).

You could also try the command he provided: ionic platform add android.

Double check Ionic page to see if you really installed everything.

Hmm, that module was automatically added by ionic. Nothing that I wrote. — Fred, Jan 24 '16 at 11:15

I created a new Ionic app with the same name and then changed the numbers that was added in the widget id to match the numbers in the old app.

If you do this on a PC and want to create an IOS app you have to move the whole app to a MAC and build it with cordova there before publishing. Otherwiser the app will have the path of the old widget ID and you won't be able to work with (for example) files downloaded in the app.
