I am not able to debug this AsyncTasc

I have set breakpoints in this AsyncTask,

I have put android:debuggable="true"

and I have added android.os.Debug.waitForDebugger();

but still the debugger (Eclipse) would not enter...

class DownloadWebpageTask extends AsyncTask<String, String, String> {
@Override
protected String doInBackground(String... urls) {
    android.os.Debug.waitForDebugger();
    try {
        Log.e("","Sono in doibacground di DownloadWebpageTask");
        return downloadUrl(urls[0]);
    } catch (IOException e) {
        return null;
    }
}

This AsyncTask is called by the following AsyncTask

public class DownloadGelaterieAsyncTask extends AsyncTask<Void, Void, ArrayList<Gelateria>> {

    @Override
    protected ArrayList<Gelateria> doInBackground(Void... params) {
            try {
                Log.e("i di doInBackground di DownloadGelaterieAsyncTask", Integer.toString(i));
                gelaterie = new DownloadWebpageTask()
                .execute( "https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=45.4667,9.1833&radius=10000&language=Italian&keyword=gelateria&key=XXXXXXXXXXX"
                                ).get();

            } catch (Exception e1) {}

What am I doing wrong?

You're calling an AsyncTask inside an AsyncTask. That's not going to work as is. All AsyncTasks are scheduled on the same thread, so the nested AsyncTask won't be executed until the first one is done -- you just locked your app.

Just refactor your first AsyncTask as follows:

public class DownloadGelaterieAsyncTask extends AsyncTask<Void, Void, ArrayList<Gelateria>> {

    @Override
    protected ArrayList<Gelateria> doInBackground(Void... params) {
            try {
                Log.e("i di doInBackground di DownloadGelaterieAsyncTask", Integer.toString(i));
                gelaterie = downloadUrl( "https://..." );

            } catch (Exception e1) {}

There's no need for nesting an AsyncTask inside an AsyncTask.
