Hi,
I've downloaded and installed Android Studio (ver 1.2.1.1) and JDK pacakge
as well. The dev environment seems to has been set up correct. And I'd
like to hack my first super simple Android app. It would perform only two
functions. First, connect to a URL and get its content (data records),
then display them. That is it, nothing fancy. I've watched a relevant
Youtube video, created the main java code using AsyncTask
and the supporting connection java code as well.
Running the app generated two errors.
The 1st one is: "error: <identifier> expected", source code: httpGet = new
(url);
// fyi, url has been defined already
And the 2nd error is:
Error:Execution failed for task ':app:compileDebugJava'.
> Compilation failed; see the compiler error output for details.
And here's the full source code

How do we fix it?
Many thanks.
