Код Android работает на 2.3, но не на 4.0

Я написал следующий код, разработанный для минимальной версии API 2.3.3, и он отлично работает на эмуляторе, предназначенном для этого. Я только что попробовал протестировать тот же код на API 4.0, и жесты onFling, которые я реализовал для управления приложением, не работают. Их вроде даже не зовут.

Вот код.

package com.mystraldesign.memorable;

import java.io.IOException;

public class MemorableActivity extends Activity implements android.view.GestureDetector.OnGestureListener,OnDoubleTapListener  
{
    //Define text views
    private TextView textView1;
    private TextView textView2;
    private TextView textView3;
    private TextView textView4;

    //Previous password holder
    private String prevPass;

    //Gesture Detectors
    private GestureDetector gTap; 

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);

        gTap  = new GestureDetector(this,(android.view.GestureDetector.OnGestureListener) this);

        //Remove title bar
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.main);




        //Define textView
        textView1 = (TextView) findViewById(R.id.textView1);
        textView2 = (TextView) findViewById(R.id.textView2);
        textView3 = (TextView) findViewById(R.id.textView3);
        textView4 = (TextView) findViewById(R.id.textView4);

        //Load font file
        Typeface type = Typeface.createFromAsset(getAssets(),"fonts/optima.ttf"); 

        //Set various textViews to font
        textView1.setTypeface(type);
        textView2.setTypeface(type);
        textView3.setTypeface(type);
        textView4.setTypeface(type);

        prevPass = "Memorable";

    }



    //Password call
    public void newPass()
    {
        //Store Return
        String retn = "";
        PassGen passWord = new PassGen();


        //Generate password
        try 
        {
            retn = passWord.passwordGen(this);
        } 
        catch (IOException e) 
        {

            //Message about Error
            Context context = getApplicationContext();
            CharSequence text = "Ooops Something Went Wrong!";
            int duration = Toast.LENGTH_SHORT;

            //Display message
            Toast toast = Toast.makeText(context, text, duration);
            toast.show();

            textView1.setText("Memorable");


            e.printStackTrace();
        }

        //Update prevPass
        prevPass = textView1.getText().toString();

        textView1.setText(retn);
    }

Консоль продолжает говорить, что не удается установить, но она появляется в эмуляторе и запускается. То же самое происходит при тестировании на реальном устройстве 4.0.

ОТРЕДАКТИРОВАНО:

Теперь он запускается и устанавливается на всех AVD (2.3.3 - 4.0), но жесты по-прежнему работают только на 2.3.3.
