Run javascript code in android browser via an intent

Ok so I was using : 

String url ="http://www.example.com";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);

To send the user to visit a url on his device's browser then I was wondering if it would be possible to send a javascript code via an intent to be run on the devices browser something like javascript:alert('hello') because typing that in the browser will run it so is it possible to do it via an intent ? If it is possible wouldnt that be some sort of security flaw in android ? Any documentation or example would be nice for further ressearch. Thanks

I would also like to mention that I have tried to pass javascript code via the setData() but it just froze the UI without giving any error.

That would depend on the browser. There are many Web browser implementations for Android. I would not assume that all Web browsers on Android support the javascript scheme in the address bar, though some might.

so is it possible to do it via an intent ?

That would depend on the browser. There are many Web browser implementations for Android. In general, I would not expect javascript to be a supported scheme, but there may be workarounds for that limitation.

If it is possible wouldnt that be some sort of security flaw in android ?

Possibly. It would depend on the browser and how it handled the Intent. There are many Web browser implementations for Android. It would not be a security flaw in Android, any more than bugs in Windows apps represent security flaws in Windows.
