java errors in dr java -

I have import java.util.ArrayList; () and then I got 2 different types of errors they are:

  Error: the type of expression should be an array type, but it is java.util.ArrayList & lt ; Java.lang.Integer & gt;    and:  
  error: the length can not be fixed or the field is not    Can you tell me what they mean? I have finally tried to change the length statements by adding  ()  but causes more errors than I started then   
 
  For an ArrayList you get the number of elements. Length. You can not treat ArrayList just like the original array. Please provide some code samples for help with another error.  
  int i = myList.size (); Edit:   I have just seen that someone in fact has already mentioned any other questions you have already made.  
 Since you try to develop a method of community-coding, so that you have some tips for development and can save some nerves to the community;)  
 Java Doc Try to open it in the browser while you code:  
 If you want to experiment with an ArrayList, then look at that method and properties, generally, how to use proper tutorials such as links, such as archive classes Here's a question Instead of posting Javadak is likely to browse quickly and this will give you a nice general picture of the original Java classes.

Integrate flash games in android app? -



    3 is a flash game that I want to integrate into a menu / list in the Android app. So when the user selects the game from the list, the game starts with the help of the Android Flash Player.   Is it better or better with webwave?   Is there any good tutorial?   Thank you! Adobe Flash provides a good way: you can create a breeze for the Android app.    Use this to create your menu and compile three games in your air app.   Here are some tutorial links about how to publish AiI for Android applications and:   PART1: AIR for Android, PART2:   Publication for Android apps: Ai:   I do not believe that the Android Flash Player can be launched with a single intention so far, so using Java Android will not solve it (now ) And   and a third approach Whatever you mentioned, it should work - using the webwave.
