TypeError: Cannot read property 'android' of null

[Spahar]

Hello, I am encountering this Exception. The thing is that it doesn't happen every time.

Error:

JS:  *** NativeScriptError *** : Error: The application crashed because of an uncaught exception. You can look at "stackTrace" or "nativeException" for more detailed information about the exception.
JS:  *** StackTrace *** : An uncaught Exception occurred on "main" thread.

I started developing the app using the tabs example.

The createBanner is called through the tabs-page.js

function onLoaded () {
    setTimeout( function() {
        admob.createBanner({
          testing: true,
          size: admob.AD_SIZE.SMART_BANNER,
          androidBannerId: "ca-app-pub-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
          margins: {
            bottom: 0
          },
          keywords: ["foo", "bar"]
        }).then(
            function() {
              console.log("admob createBanner done");
            },
            function(error) {
              console.log("admob createBanner error: " + error);
            }
        );
    }, 1500);
}

exports.onLoaded = onLoaded;

Any suggestions?

Thanks

increase setTimeout Time from 1500 to 4000 for example and try

First of all, thanks for the reply.

I have thought of that, but I don't believe this is a permanent solution. Because sometime for some reason, even 4 seconds won't be enough.

Apart from finding a fix, is there a way to suppress the exception so it wont crash the app?

[Spahar]

This fix proposed from RoyiNamir here seems to do the trick.

Applied the fix, cheers!
