Situation :
I am working on Client-Server Communication.
When the users save the data (name of product, image, note), it should be transferred to the server side of the database.
But, I don't know how to code http Post request on the client side(Android).
MyWishlistsActivity.java
public class MyWishlistsActivity extends ListActivity {

@Override
public void onCreate(Bundle savedInstanceState) {

int[] to = new int[] { R.id.name };
custAdapter = new CustomWishlistsAdapter(this,R.layout.wishlist_list_item, null, from, to);
this.setListAdapter(custAdapter);
}
@Override
protected void onResume() {
super.onResume();
new GetContacts().execute((Object[]) null);
}
@SuppressWarnings("deprecation")
@Override

Cursor cursor = custAdapter.getCursor();
if (cursor != null)
cursor.deactivate();
custAdapter.changeCursor(null);
super.onStop();
}
