Hello all,
I've installed the android SDK, Eclipse and the ADT plugin (got all
the latest versions from the official websites: eclipse 3.4.2 from
which I installed the ADT plugin and SDK 1.1_r1 from google).
I've set the SDK in eclipse and also added it to the PATH environment
variable (I'm running Win XP SP2) and have entered the necessary Run
configurations settings in eclipse.
Yet trying to open each of the sample projects and create a Hello
Android project of my own consistently gets the following error from
eclipse: R cannot be resolved.
I still don't know much about the framework but have read that the
R.java is suppose to be generated automatically. Eclipse suggests
adding an import to android.R, but the tutorial I'm reading seems to
have no such import and even if I add the import the problem persist
as the 'main' class simply isn't there.
I've changed the relevant code so to omit the use of the R class from
this:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
to this:
TextView tv = new TextView(this);
tv.setText("Hello, Android");
setContentView(tv);
While this did make the aforementioned error go away I still couldn't
run the project since eclipse doesn't seem to work well with the ADT
plugin (that's my guess at least) and the doesn't build the project.
When I Run it I get the following output on the console:
[2009-03-08 09:19:09 - Hello Android] ----------------------
[2009-03-08 09:19:09 - Hello Android] Android Launch!
[2009-03-08 09:19:09 - Hello Android] adb is running normally.
[2009-03-08 09:19:09 - Hello Android] Could not find Hello
Android.apk!
The emulatore doesn't start of course. It seems to me like there's a
problem with the ADT and Eclipse so that the projects aren't created
properly (that R.java file is suppose to be created automatically
according to what I've read).
any clues as to what's gone wrong here and how can I fix it?
