View 1 Replies View RelatedWriting JUnit-Test For Some Of Classes - Getting Android Class Errors?
Apr 2, 2012The problem is, that I wanted to write a JUnit-Test for some of my classes - but this stupid Anroid SDK does always lauch this absolutely lame AVD!
So I came up with the idea to move all my non-Android related classes out of the actual Android project into standard Java project. There I can easily test my classes and by adding this standard Java project to the BuildPath of the Android project, I can easily access and use my classes: no error is shown in the IDE - everything is fine.
But if I launch my full application in the AVD, it exits with following exception: NoClassDefFoundError!
I found out, how to run a normal test from an Android project. But why is it not possible to reference to a non-Android project? Regarding code reuse, this is really big disadvantage!

View 1 Replies View RelatedAndroid : Create A Library For Different Classes?
Jul 17, 2010I'm new to JNI, i'm developing a native library for an Android project. I read some papers about JNI programming but i didn't understand if it is possible to create a library that can be loaded in different project classes with different packages. I read that to declare a new JNI method the syntax is:
the prefix "Java_"
an encoded fully qualified class name
an underscore ("_") separator
an encoded method name
Based on this definition it shouldn't be possible...
Suppose i had defined a class A in the package pkg1 with the native method foo contained in libfoo, and then i defined a class B in the package pkg2. Can i use libfoo and the foo method in B? How should i define the native method to achieve the result?

View 2 Replies View RelatedAndroid :: Sending An Object To A Library Class
Aug 28, 2010I'm attempting to make a simple homebrew game engine/framework in android. I have the "engine" as a library project that handles all of the graphics rendering, game activity, and whatnot. Essentially, the library project has a class GameMain which has a background image, an array of drawables, and a few functions (the most important is a run() function). The projects that use this library extend this class with their own unique run() function. The idea is that games that use the engine start with their own activity, launch the GameActivity from the library, and pass their unique GameMain child object into the library, which should run the unique run() method thanks to polymorphism.
Getting this to work, however, has been a struggle. I originally attempted to make the GameMain Serializable, which didn't appear to work. I'm now attempting to make it a Parcelable, but it does not appear to run the child objects run() function when called from the library. I'm wondering, are Parcelable objects actually capable of sending Object methods across activities? Am I going about this the wrong way, or am I just having some other weird bug I have not uncovered?
Android : When To Use Layouts / Create New Activity Classes?
Mar 3, 2010I'm writing a game for Android. My GUI has the following basic screens (i.e. the information and interactions required on each of these would take up the whole display):
Main menu (let you start a new game, enter settings, see high scores, see about screen)
Game screen i.e. where the actual game is played.
Settings screen.
High scores screen.
About screen (i.e. credits and a back button)
Game over screen (arrived at when the game ends)
Pause screen (pauses game and can access settings)
The following are some example transitions the user might make between these screens:
1->2->7->2->6 (starts new game, pauses game, returns to game, finishes game)
1->5->1->4->1 (views about screen, goes back to main, views score screen, goes back to main)
I'm really confused about when to have just one activity that switches layouts and when to create new activity classes. For example, when my game loads, I have a "main" activity that loads the main menu layout. When you click the settings button, I launch a "settings" activity (which uses android's standard settings GUI). For the moment, when you start a game, I switch the layout of "main" to the game screen layout (which just contains one big surface view). I'm not really sure what the best way to integrate the game over screen, high score screen, about screen etc.
Creating a new activity for each seems really heavy weight to me. There's quite a lot of boiler plate code involved for each activity. Plus, communication between activities seems like a pain as you have to use bundles. Using just one activity means I can just share object fields directly. It seems that using layouts for the above would be more compact. Can anyone give me some recommendations?

Oct 3, 2010I have a class A which is responsible for fetching data from web services in android and i have a class B which is responsible for creating and rendering List View in android
Now how can i populate data on List View once the data is fetched successfully.
well i have following options but which one is better .. (if someone has anyother then i don't mind)
1) Create an intent of Class B and
pass the data that need to be

in class B i have used Holder Patter to create ListActivity. ( for reference List14.java in samples of Android )
Android :: Pass In Object Java Class Embedded In As Parameter
Apr 19, 2010I'm building an android application, which has a list view, and in the list view, a click listener, containing an onItemClick method. So I have something like this:
public class myList extends ListActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
getListView().setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
/* Do something*/
}
}
}
Normally, this works fine. However, many times I find myself needing too preform an application using the outer class as a context. thusfar, I've used: parent.getContext(); to do this, but I would like to know, is that a bad idea? I can't really call: because it's not really a subclass, just an embedded one. So is there any better way, or is that considered cosure? Also, if it is the right way, what should I do if the embedded method doesn't have a parameter to get the outside class?
Android :: Class That Turns That An XML String Into Java Object - ClassNotFoundException
Jun 22, 2010So I ran into a problem today while working on my Android program. I have a class that turns that an XML string into a Java object (third party) and it works fine in as a regular java project but on Android I get this weird error:
CODE:.......
I hide my application name and my package for obvious reasons but I was wondering if anyone has ever encountered problems like this. Class is in the correct package, which is a library I have added. Other classes that I reference before are there and those can be made. Are there any other reasons a ClassNotFound Exception is thrown?

Android :: Static Fields In Activity Classes Guaranteed To Outlive Create / Destroy Cycle?
Oct 28, 2009I frequently run into the problem that I have to preserve state between several invocations of an activity (i.e. going through several onCreate()/onDelete() cycles). Unfortunately, Android's support for doing that is really poor. As an easy way to preserve state, I thought that since the class is only loaded once by the class loader, that it would be safe to store temporary data that's shared between several instances of an activity in a static Bundle field. However, occasionally, when instance A creates the static bundle and stores data in it, then gets destroyed, and instance B tries to read from it, the static field is suddenly NULL. Doesn't that mean that the class had been removed and reloaded by the classloader while the activity was going through a create/destroy cycle? How else could a static field suddenly become NULL when it was referencing an object before?
