How to get list of apps from android market?

Question

I am going to create application like Google Play Store. I want to retrieve a list of apps like free apps, paid apps, categorized apps (Social, Entertainment, Business, etc.) from the Android Market and process it to be displayed on my application screen.

I don't know how to get the list of app details from the Google Play Store. Please suggest ideas, URLs (to guides), or code snippets to list app details.

Help me. Thank you in advance.

I tried like this

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    try {

        login = (Button) findViewById(R.id.login);
        mailid = (EditText) findViewById(R.id.username);
        number = (EditText) findViewById(R.id.password);

        login.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) { // TODO Auto-generated
                email = mailid.getText().toString();
                password = number.getText().toString();

                try {
                    Backgroundprocess Task1 = new Backgroundprocess();
                    try {
                        Task1.execute();
                    } catch (Exception e) {
                        // TODO: handle exception
                        e.getStackTrace();
                    }

                } catch (Exception e) {
                    // TODO: handle exception
                    e.getStackTrace();
                    Log.d(tag1, e.toString());
                }

            }
        });

    } catch (Exception e) {
        // TODO: handle exception
        e.getStackTrace();
        Log.d(tag2, e.toString());

    }
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}

private class Backgroundprocess extends AsyncTask {

    protected void onPostExecute(final Void unused) {

    }

    @Override
    protected Void doInBackground(String... params) {
        // TODO Auto-generated method stub
        try {
            MarketSession session = new MarketSession();
            String android_id = Secure.getString(getBaseContext()
                    .getContentResolver(), Secure.ANDROID_ID);
            session.login(email, password);

            session.getContext().setAndroidId(android_id);
            String query = "maps";
            AppsRequest appsRequest = AppsRequest.newBuilder()
                    .setQuery(query).setStartIndex(0).setEntriesCount(2)
                    .setWithExtendedInfo(true).build();

            session.append(appsRequest, new Callback() {
                @Override
                public void onResult(ResponseContext context,
                        AppsResponse response) {
                    // Your code here
                    // response.getApp(0).getCreator() ...
                    // see AppsResponse class definition for more infos

                }
            });
            session.flush();

        } catch (Exception e) {
            // TODO: handle exception
            e.getStackTrace();
            Log.d(tag3, e.toString());
        }
        return null;
    }
}
