COCOS2D AND XCODE

I have been testing out Cocos2d and after installing it xCode started going crazy.

'New File' started crashing

I have installed cocos2d 1.0.1 on xCode 3.2.6, everything is okay, templates are installed and HelloWorld project compiles successfuly.
But when i need to create a new class,after clicking on "New File" i will get this error twice:

File: /SourceCache/DevToolsIDE/DevToolsIDE-1760/pbxinterface/Wizards.subproj/PBXWizardChooserWizard.m
Line: 1158
Object:
Method: _addWizardProxiesFromBaseSearchPath:subpath:

Assertion failed: _currentMultiWizard == nil

I had to delete any folder called cocos2d in both my user and system Libraries:

/Library/Application Support/Developer/Shared/Xcode/File Templates/

Adding References to Libraries in XCode

It did not work the way that I thought it would.

The tutorial I found that got me past the obvious issues was this:

This tutorial also helped:

First iOS Bug Cycle

I ran into a compile error today working on an iPhone application using Cocos2d.

The error was:

[CCTouchDispatcher addTargetDelegate:priority:swallowsTouches:]: unrecognized selector sent to instance

and I entered that into Google.

A few results down I found this link:

https://github.com/clops/SneakyInput/commit/318939caa03ce7435f1a46079464104737441ecc

Which shows a fix that is totally irrelevant to my issue.

I later figured it out on my own. Learning iPhone development so far is fun, but slower than Android.

Android Application Trouble with "android.hardware.screen.landscape"

The Problem:

When you upload your APK to the Android Market it is flagged with an awful and mysterious permisison called "android.hardware.screen.landscape" and this limits your devices to a very small number.


The Issue:

You have a landscape application that does not support portrait. However, your application will run on many devices that are rotated even if they do not specifically have the landscape hardware (ie, no portrait mode?)


The Solution:

Add the following line to your AndroidManifest.xml and everything will be fine.




Notes


At some point Google added this as a filter during upload. It came on and off for a while depending on what SDK you use. Various people have posted / Tweet'd that it can be fixed with an SDK upgrade. That may or may not be true on your platform or at the time you read this.

Android ADT Eclipse: Unknown error: java.lang.NullPointerException

Do you have this error?

[2011-06-03 09:52:51 - AndroidSamNinteen] Unknown error: java.lang.NullPointerException

If you have this error, GIVE UP NOW.

This error cannot be fixed.

Eclipse is corrupted in a way that cannot be recovered.

the only solution I have ever found (sixth time) is the second you see this error, remove everything, delete all files and start over.

1. New install of Eclipse

2. New install of ADT

3. Recreate project by hand (import source files)

4. Now it will build

Dealing with the "gen" folder in Android -- Clean, Error, Clean, Build, Etc

From StackOverflow:

http://stackoverflow.com/questions/3820517/clean-in-eclipse-temporarily-destroys-android-project-with-error-message-missing

So valuable I needed to repost it

We have finally tracked the last problem regarding this bug.

The "clean" action used to always delete the "gen" folder which was wrong. This was fixed in ADT 8 or 9, I can't remember.

However, if the "gen" folder is marked as derived it still gets deleted which leads to the error.

When the "New Project Wizard" is run, the gen folder is created normally, without the "derived" flag, so this is fine.

The following scenario however is broken:

• delete manually gen, or

• check in the source code in a repository (git/svn/...) and don't put the "gen" folder in there, then do a check out on another computer.

• This leads to ADT recreating automatically the "gen" folder during build, this time enabling the "derived" flag, which will trigger the wrong behavior on "clean".

The temporary solution is to:

• right click "gen"
• choose "Properties"
• uncheck "Derived"

as long as the "gen" folder doesn't get deleted you'll be able to clean your project without side effect.

I just checked in a fix to: - never mark the folder as "derived" - during clean, first remove the "derived" flag from "gen" so that it doesn't get deleted in the case of older projects. Patch is visible at:https://review.source.android.com/#change,22410

Refactoring Tools: Eclipse v. Visual Studio 2010

After coding with both Visual Studio 2010 Professional and Eclipse Basic 3.6 I can honestly say, Visual Studio sucks at refactoring.

The basic "change method signature" tool in Eclipse -- which is free -- is honestly at least 5 times better than the Visual Studio version which cost me -- literally -- thousands of dollars.

It seems that the best way to get Visual Studio to refactor at roughly the same level as Eclipse is to purchase ANOTHER commercial product -- ReSharper to plug into Visual Studio and bring up the refactoring. Really?
