Google Quality Problems in Android 4.3

I know that I am very disappointed to learn that the Android team's quality control process is so lacking that it permits issues like this to reach production:

https://code.google.com/p/android/issues/detail?id=58385

I just think that at this point it appears that Android, the OS and the toolchain, have grown too complex for Google's teams to handle.

Google, and the Android team, are rapidly falling behind on quality in both the development tools and the OS releases, even for flagship devices like the Nexus 7 and Nexus 10.

This issue above is only one of a dozen fatal flaws in the Android OS and recent releases of the ADT have exhibited similar lapses in discipline.

I would speculate that this could represent a chance for someone seeking to take marketshare from Google with developers to capitalize on Google's current weak position.

Now, once you get through all that then you start digging into the API
http://developer.android.com/google/play/billing/v2/api.html

You will have errors. They might be this error about developer keys:
http://stackoverflow.com/questions/11068686/this-version-of-the-application-is-not-configured-for-billing-through-google-pla

A typical in-app billing implementation relies on three components:

• A Service (namedBillingService in the sample application), which processes purchase messages from the application and sends billing requests to the Google Play in-app billing service.
• A BroadcastReceiver (namedBillingReceiver in the sample application), which receives all asynchronous billing responses from the Google Play application.
• A security component (named Security in the sample application), which performs security-related tasks, such as signature verification and nonce generation. For more information about in-app billing security, seeSecurity controls later in this document.

You may also want to incorporate two other components to support in-app billing:

• A response Handler (named ResponseHandler in the sample application), which provides application-specific processing of purchase notifications, errors, and other status messages.
• An observer (named PurchaseObserver in the sample application), which is responsible for sending callbacks to your application so you can update your user interface with purchase information and status.

In addition to these components, your application must provide a way to store information about users' purchases and some sort of user interface that lets users select items to purchase. You do not need to provide a checkout user interface. When a user initiates an in-app purchase, the Google Play application presents the checkout user interface to your user. When the user completes the checkout process, your application resumes.

Using with JNI Stack Traces Debug JNI / C++ in Android SYSTEM_TOMBSTONE

First, your application which is written in C++ or being invoked over JNI will crash.

Hello! Honestly we both know it will crash a whole shitload. It's JNI -- what it really does is crash.

So, first we're writing JNI and that ensures we'll see this type of trash spewing out of logcat regularly.

That entire mess is worthless to us.

Foreign-language-we-do-not-know worthless to us.

We need to translate:

• First, we download the data from the device (needs root.)
• Second, we locate the translation tables (comes from the build.)
• Third, we mash it all together with ndk-stack (comes from the NDK.)

Download the Tombstone Stack Traces

I ran the command

G:\stacks>"C:\Program Files (x86)\Android\android-sdk-windows\platform-tools\adb.exe" pull /data/tombstones/

Had to make sure I had my shell running somewhere with permissions so that adb could write the tombstone files (AKA, not C:\Program Files)

ADB will chew on this for a minute and then print something like this:

pull: building file list...

pull: /data/tombstones/tombstone_01 -> ./tombstone_01

pull: /data/tombstones/tombstone_06 -> ./tombstone_06

pull: /data/tombstones/tombstone_07 -> ./tombstone_07

pull: /data/tombstones/tombstone_00 -> ./tombstone_00

pull: /data/tombstones/tombstone_03 -> ./tombstone_03

10 files pulled. 0 files skipped.

1564 KB/s (607224 bytes in 0.379s)

This cannot be helped but at least your files were downloaded (if you were lucky.)

Locate the Translation Objects

They are located in {PROJ.ROOT}\obj\local\armeabi\

If you are using Cocos2d-x then it is like this:

G:\cocos2d-2.1rc0-x-2.1.2\YourCoolGame\proj.android\obj\local\armeabi

Run NDK-Stack

I ran the command

G:\android-ndk-r8d\ndk-stack.exe -sym G:\cocos2d-2.1rc0-x-2.1.2\HeroesOfSteel\proj.android\obj\local\armeabi -dump G:\strace\tombstone_06

If you do it all right you get something that looks like this and might tell you something about what is wrong with your program. Probably not. But it does include some line numbers which is better than afd11060 e2166903 1a000017 e5945000 e1a02004.

So this is what it ends up looking like:

Tracking SQLite3 Database Version with user_version Pragma

Building an SQLite3 layer into your games without the help of Android's awesome SQLiteOpenHelper? One thing you will need to keep track of is the version of the schema in use in your SQLite database.

Thankfully, the SQLite database and the API for accessing it provides some functions that will help you out.

in particular, these commands are "pragma" which reads and sets values in a properties list of the database and "user_version" which is an in-built database property intended to be used to track schema version.

sqlite> pragma user_version=10;
sqlite> pragma user_version;
user_version
------------------------------
10

sqlite> pragma user_version=12;
sqlite> pragma user_version;
user_version
------------------------------
12

This is the same process that your SQLiteOpenHelper implementation with Android uses, and provides you the ability to write onCreate and onUpdate methods as you would in Java.

Using Cocos Builder with Cocos2D-x

Reading the source code for some tests really helps

https://projects.developer.nokia.com/cocos2dxqt/browser/tests/tests/ExtensionsTest/ControlExtensionTest/CCControlButtonTest/CCControlButtonTest.cpp

But by far the most important thing is this documentation:

Translation: "You have put the wrong object type into the CCB file, under 'CustomClass' on your CCLayer.

Probably you put in your Scene not your child of  cocos2d::CCLayer and 

public cocos2d::extension::CCBSelectorResolver

Easy to fix once you figure out what that assertion is testing.

Using 2.0? They have moved sharedDispatcher

http://stackoverflow.com/questions/11264191/cocos2d-x-cctouchdispatcher-no-shareddispatcher

Use this:
CCDirector::sharedDirector()->getTouchDispatcher();

Not that:
CCTouchDispatcher::sharedDispatcher()->getTouchDispatcher();



Fixing Compile Issues with Visual Studio Project (.csproj) calling CCEGLView::create?

1. Open Property of Project.
2. Change the item value of "Character Set" to "Use Multi-Byte Character Set".
3. Rebuild your project.

'setIsTouchEnabled' : is not a member of 'HelloWorld'

If you are upgrading from Coocs2dx 1.x to Cocos2dx 2.x you will have a lot of conversion to do.

If you get the error:

'setIsTouchEnabled' : is not a member of 'HelloWorld'

you really want to switch the code to this:

this->setTouchEnabled(true);

You might struggle with how to convert a CCObject to an int. Use this type of cast:

int x = ((CCString *)spawnPoint->objectForKey("x"))->intValue();

---

You might also struggle with callfunc, which is very simple to use in Objective-C but not so easy in Cocos2dx.

This tutorial was very useful building a demo game in Cocos2dx

http://www.raywenderlich.com/1163/how-to-make-a-tile-based-game-with-cocos2d

I was already familiar with it from using Cocos2d.

---

This commit is really large, but shows a lot of useful conversion moves from early Coocos2dx to modern. This guy or girl knew what he/she was doing and made quick work of a lot of before/after conversion code that made doing similar work on my side very easy. Just search for the code I had and found what they changed it to.

Often we need to concatenate strings using the + operator. A shortcut way to do this in C++ is as follows:

CCSprite *sprite = CCSprite::spriteWithFile((name+".png").c_str());

This was kinda useful tutorial to introduce Cocos2d vs. Cocos2dx from a memory and reference counting standpoint:

Cocos2dx Setup: Windows 7 Visual Studio and Eclipse

I have been working on building a cocos2dx application that runs on Windows 7 x64 in Visual Studio, Eclipse, iPhone and MacOS X.

I started with this setup guide:

http://www.cocos2d-x.org/projects/cocos2d-x/wiki/How_to_set_up_the_Android_Cocos2D-x_development_environment_on_Windows_7

I had to do a lot of installing ....

• Cocos2d-2.0x (same download for Mac OS X and Win32)
• NDK r8d on Mac OS X and Windows (different downloads for Mac OS X and Win32)
• Newest ADT and Android SDK on Mac OS X and Windows (different downloads)
• Native Development Tools -- Eclipse Plugin
• Android Development Tools -- Eclipse Plugin
• Cygwin on Windows (with : autoconf, automake, binutils, gcc-core, gcc-g++, gcc4-core, gcc4-g++, gdb, pcre, pcre-devel, gawk, make)
• Visual Studio 2010 C++ Language Support
• Eclipse CDT (C++ Development Tools)
• Several Eclipse, Java, Windows and Mac OS X Updates along the way

---

In the end, I believe that the correct way to configure the application is to have a folder for the project and sub-folders as follows:

• \cocos2d-2.0-x-2.0.4\TileMapGame\Classes
• \cocos2d-2.0-x-2.0.4\TileMapGame\Resources
• \cocos2d-2.0-x-2.0.4\TileMapGame\proj.android
• \cocos2d-2.0-x-2.0.4\TileMapGame\proj.win32

---

You can get this far using two included .sh scripts

• \cocos2d-2.0-x-2.0.4\create-android-project.bat
• \cocos2d-2.0-x-2.0.4\create-android-project.sh

---

You will quickly notice that Cocos2d-2.0-x does not come with an easy facility to create an XCode project folder the way it does for Visual Studio and Eclipse.

To create the following folders I used Notepad2 and editing the .xcodeproj files

• \cocos2d-2.0-x-2.0.4\TileMapGame\proj.ios
• \cocos2d-2.0-x-2.0.4\TileMapGame\proj.mac

I started by copying over these folders

• \cocos2d-2.0-x-2.0.4\samples\HelloCpp\proj.ios
• \cocos2d-2.0-x-2.0.4\samples\HelloCpp\proj.mac

Then I made some important changes

• Changed relative paths to 'cocos2dx.xcodeproj'
• Renamed Project
• Reconnected plist file
• Fixed "Header Search Paths" to include correct relative paths
• Converted "Resource" sub-folders to 'groups' by deleting and re-adding
• Added CocosDenshion group and added 'ios' and 'include' folders
• Added missing frameworks
• AudioToolkit
• OpenAL
• AVFoundation
• Set 'version' and deployment targets for iOS and Mac OS X

---

So at the end I have this structure

• \cocos2d-2.0-x-2.0.4\TileMapGame\Classes
• \cocos2d-2.0-x-2.0.4\TileMapGame\Resources
• \cocos2d-2.0-x-2.0.4\TileMapGame\proj.android
• \cocos2d-2.0-x-2.0.4\TileMapGame\proj.win32
• \cocos2d-2.0-x-2.0.4\TileMapGame\proj.ios
• \cocos2d-2.0-x-2.0.4\TileMapGame\proj.mac

The only two I have not created are 'proj.linux' and 'proj.blackberry' because at this time I do not have any need for them.

Convert from iPhone to iPad XIB

You can convert iPhone xib into iPad xib using following step.

Right click the file (in xcode) and Open As > Source Code

The 2nd line should look like:

 type="com.apple.InterfaceBuilder3.CocoaTouch.XIB" version="7.10">
Replace with:

 type="com.apple.InterfaceBuilder3.CocoaTouch.iPad.XIB" version="7.10">

Search for "IBCocoaTouchFramework" and Replace all occurrences with "IBIPadFramework"

Save the file and Open As > Interface Builder - iOS

you can do this for al xib...and you have your iPhone xib now in iPad xib.
