This is generated following the tutorials found here

Thanks for any help

Answer 1

Maybe the SDK ins't set up properly? try re-installing the Android SDK (http://developer.android.com/sdk/index.html)

Answer 2

Could it be that in your test class' constructor you have the following code:

public HelloAndroidTest() {
    super("com.example.helloandroid.HelloAndroid", HelloAndroid.class);
}

instead of this code:

public HelloAndroidTest() {
    super("com.example.helloandroid", HelloAndroid.class);
}

?

I just ran into a similar issue, and that was it's solution.
