Android ("vanilla" android without custom launchers and touch interfaces) does not allow changing of the application icon, because it is sealed in the .apk tightly once the program is compiled. There is no way to change it to a 'drawable' programmatically using standard APIs. You may achieve your goal by using a widget instead of an icon. Widgets are customisable. Please read this :http://www.cnet.com/8301-19736_1-10278814-251.html and this http://developer.android.com/guide/topics/appwidgets/index.html. Also look here: https://github.com/jgilfelt/android-viewbadger. It can help you.

As for badge numbers. As I said before - there is no standard way for doing this. But we all know that Android is an open operating system and we can do everything we want with it, so the only way to add a badge number - is either to use some 3-rd party apps or custom launchers, or front-end touch interfaces: Samsung TouchWiz or Sony Xperia's interface. Other answers use this capabilities and you can search for this on stackoverflow, e.g. here. But I will repeat one more time: there is no standard API for this and I want to say it is a bad practice. App's icon notification badge is an iOS pattern and it should not be used in Android apps anyway. In Andrioid there is a status bar notifications for these purposes:http://developer.android.com/guide/topics/ui/notifiers/notifications.html So, if Facebook or someone other use this - it is not a common pattern or trend we should consider. But if you insist anyway and don't want to use home screen widgets then look here, please:

How does Facebook add badge numbers on app icon in Android?

As you see this is not an actual Facebook app it's TouchWiz. In vanilla android this can be achieved with Nova Launcher http://forums.androidcentral.com/android-applications/199709-how-guide-global-badge-notifications.html So if you will see icon badges somewhere, be sure it is either a 3-rd party launcher or touch interface (frontend wrapper). May be sometime Google will add this capability to the standard Android API.

This will do what you want, with either an image of fixed height, or calculated programatically.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <RelativeLayout
        android:id="@+id/layoutTop"
        android:layout_width="match_parent"
        android:layout_height="200dp" >
    </RelativeLayout>

    <RelativeLayout
        android:id="@+id/layoutBottom"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_alignParentBottom="true"
        android:layout_below="@id/layoutTop" >
    </RelativeLayout>

    <ImageView
        android:id="@+id/overlapImage"
        android:layout_width="wrap_content"
        android:layout_height="40dp"
        android:layout_above="@id/layoutBottom"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="-20dp" <!-- This should be always half the height, can also be calculated and added programtically -->
        android:adjustViewBounds="true"
        android:src="@drawable/ic_launcher" />

</RelativeLayout>

In my solution, whenever a new notification arrives, the counter will increase (as observed in shopping apps)

Try this, it works on my MOTO e2.

Make sure your API Level > 14

Create a layout like:

</RelativeLayout>
    <ImageView
        android:id="@+id/counterBackground"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/unread_background" />

    <TextView
        android:id="@+id/count"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="1"
        android:textSize="8sp"
        android:layout_centerInParent="true"
        android:textColor="#FFFFFF" />
</RelativeLayout>

In onCreateOptionMenu,

@Override
public boolean onCreateOptionsMenu(Menu menu) {
   getMenuInflater().inflate(R.menu.menu_main, menu);

   MenuItem menuItem = menu.findItem(R.id.testAction);
   menuItem.setIcon(buildCounterDrawable(count,  R.drawable.ic_menu_gallery));

   return true;
}

Now, build method for Icon :

private Drawable buildCounterDrawable(int count, int backgroundImageId) {
    LayoutInflater inflater = LayoutInflater.from(this);
    View view = inflater.inflate(R.layout.counter_menuitem_layout, null);
    view.setBackgroundResource(backgroundImageId);

    if (count == 0) {
        View counterTextPanel = view.findViewById(R.id.counterValuePanel);
        counterTextPanel.setVisibility(View.GONE);
    } else {
        TextView textView = (TextView) view.findViewById(R.id.count);
        textView.setText("" + count);
    }

    view.measure(View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED),
            View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
    view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());

    view.setDrawingCacheEnabled(true);
    view.setDrawingCacheQuality(View.DRAWING_CACHE_QUALITY_HIGH);
    Bitmap bitmap = Bitmap.createBitmap(view.getDrawingCache());
    view.setDrawingCacheEnabled(false);

    return new BitmapDrawable(getResources(), bitmap);
}

To change the stores that your app appears in, log into iTunesConnect and click "Manage Your Apps." Select your app and click the "Rights and Pricing" button. You can select the stores you want from this page. (If you see a line at the bottom that says "Unless you select specific stores...", your app is already for sale in all stores.)

In your getView(), change

return parent;      

to

return rowView;

getView() should return the row view and not the parent where the rows are placed in. The parent view is only supplied as a paramteter so that view inflation can deal with match_parent sizes and such.
