Google I/O 2011: Bringing C and C++ Games to Android

[stiftersd]

Really long video

[jamelt]

the first guys sarcasm is on hundred thousand trillion

[kingcrimson234]

i am going to look into the new NDK. i've got an x86 PC emulator that I wrote in plain old C that i would love to port to android, and i sure as hell am not going to rewrite THAT in java. can you imagine an interpreting x86 CPU emulator running in java on the processors that you find in a phone? :shudders:

[ss4cypher]

isn't linux c?

<_<

@Mega1hacker He would look better bold xD

Is that a Mac I see???

[chillipepper117]

thumbs up if you'd rather code for Windows phone 7 (mango)

[ChristopheMcGuinness]

@chillipepper117

DON'T MAKE ME LAUGH!!

[chillipepper117]

@ChristopheMcGuinness lol sir don't be stupid google android is a joke haha its apps are coded in JAVA!!!! BIG TIME FAIL!

[ChristopheMcGuinness]

@chillipepper117

Your missing the point the development process is a lot easier and you can now program I'm C/C++ Young Developers can get there foot in the door, its never been so easy to make apps.

[RedClownKnight2]

oh wut...

Free Sony Ericson Xperia??

Oh hell yeah!

Questions for Programmers: Is it the feature of C++ that can access Memory (pointers) which makes it powerfull than Java or something else?

[bustaballs]

@FedericoJimbo Pointers are just one of the things that make C++ far more powerful than Java. C++ is also much much faster than Java.

What makes Java appealing is that it works on everything with no need to "port" or compile for various systems. When you develop an app for a phone in Java, it will run on Windows, Mac, iOS, Linux, Unix, and every other OS that supports Java. If you develop for multiple platforms and you don't develop things that are very resource intensive, Java is ideal.

[FedericoJimbo]

@bustaballs I see, for every os your will right separate C++ code,.

[bustaballs]

@FedericoJimbo Not necessarily. You always have to, at the very least, compile the code for the different OS or platform. In Java, the compiled code will run on anything that supports java. Some libraries are only supported on certain operating systems and platforms so sometimes you have to port the code to a different library. When developers program in C/C++ for Xbox 360, they might use direct x to make the game. However, the PS3 and Wii do not support direct x so they must port the code.

[SnowWolf91]

@bustaballs I thought iOS didn't support Java?

[kbo206]

Java is the best language for very little of anything...

[JayDamnit]

I would not attend such a session, the questions people ask at the end are dumb as fuck heh. Half of them reflect a sort of "Hey look at me, give me attention" desperate need, their one spot at getting recognition from these people instead of using.. oh what.. the standard mailing lists :)

[mathgeekphysics]

Do you have to know C prior to learning C++?

[randomname123ish]

@mathgeekphysics No

[dwat2012]

@mathgeekphysics nope, im learning C++ and i dont know strict C, there are bascilly the same from what i hear

[FedericoJimbo]

@mathgeekphysics yes.... but in the sense because C syntax and features is a subset of C.... that means if you bought a book of C++ the essential topics on C will be tackled for sure..

[biggerben2010]

@kaydub403 yes you can make an android app without java. C/C++

[kaydub403]

-using c++*

[kaydub403]

could i actually make an app for android wit out using or knowing java at all?

[kaydub403]

Is both dalvik AND NDK virtual machines?

[pufixas]

OMG... Now I understand how noob at C++ I am...

I need to continue learning! I want to develop something for android... :)

[pufixas]

C++ RULES!!! :)

[lunardust201]

Yaa why are my jpegs slower duurrr. Um shut up now dude

[dravorek]

@lunardust201 actually it was the PNGs that were slower and it was an interesting question. Seeing as how the DCT transformations for decoding the JPGs should take more CPU time than the PNG decoding. Maybe he should've let it go after it was clear that they didn't know why but no reason to get upset. Just chill.

[nitrousdigital007]

Why oh why didn't I attend this session!!!?

See 49m 52s into this video for my motivations :)

[jellyfaceification]

@nitrousdigital007 49:52

[videoofmike]

eat ios alive.

[crystalclear506]

I'm Coding in C++ while watching this :)

[fedekiller]

Shameless first comment :D
