Yes, I heard they were making this actually happen...
As for building Apps in C/C++ Native..
Pros:
-More Stable
-More Unique (no Android UI features unless integrated)
-More Sophisticated
-Will open to a more known (learned) framework, by this I mean if you know C/C++ and already have apps built for other mobile devices it should be much easier to port it over to Android (look out for the flood Android Market)
-Other open sourced / commercial apps will be more easily ported...some ideas?...START A THREAD!!!...but just for the record...Apache...FireFox...just about anything that has an open source that relies on C programming...crap you can even extend this by adding Ruby, Perl...etc.
-Remember, this is a Development Kit...it just adds tools to the 1.5 SDK that allow you to create C based applications and build them in the android environment. All your apps should still work going back to RC-30 or even further back...depends on the kernel support I would guess.
Cons:
Much Larger Apps (file size)
Need to learn how the Linux Kernel works (for developers)
Other:
Load times? Ok, so for example if you have one app...say...TuneWiki...just an example of a popular resource hog...if it were to be redeveloped under C++ and optimized for the Android Modified Linux Kernel...your resources could easily be cut in half since you are not relying on the Dalvik VM.
SO...outcome?
Better for all, as long as you know what you are doing.
We should also see a huge upswing in crapware on the market from student programmers doing C++ projects on an easy open-sourced mobile platform (that has a public SDK).
So you'll see a lot of "Hello World" type apps that will have next to no function...have fun with those...................

The opposite actually. Poorly written interpreted code breaks elegantly in a vm. Poorly written compiled code can take a whole system down.

I've seen some very sophisticated Java and some **** C/C++. Don't assume that higher level programming languages are necessarily less sophisticated than lower level ones.

The NDK will enable some applications that couldn't previously have been done in the Dalvik vm for performance issues, but it isn't going to be a "flood". Fact of the matter is a lot of developers who have needed native performance or didn't want to rewrite a C/C++ codebase have deployed native code already.
but just for the record...Apache...FireFox...just about anything that has an open source that relies on C programming...crap you can even extend this by adding Ruby, Perl...etc.

FF is written in C++... [edit: I should also point out that the NDK provides for native code support in the form of libraries (mainly as a helper for computation-intensive functions). Nothing in the way of window managers or other UI is addressed, meaning for the majority of "visible" C/C++ apps the developer would have to rewrite a significant portion in Java still.]
Cons:
Much Larger Apps (file size)
Need to learn how the Linux Kernel works (for developers)

I don't know what to say other than these two statements are generally incorrect. There are two main cons to using NDK as opposed to the standard SDK, and they are 1) Reduced (or no) compatibility on future Android devices 2) Significantly reduced ease of debugging.
very interesting...subscribed

Not true. This isn't full native code apps, this is the ability to call native libraries in a davlik app.
From the actual NDK page ...
The NDK provides:
A set of tools and build files used to generate native code libraries from C and C++ sources
A way to embed the corresponding native libraries into application package files (.apks) that can be deployed on Android devices
A set of native system headers and libraries that will be supported in all future versions of the Android platform, starting from Android 1.5
Documentation, samples, and tutorials
Please note that the NDK does not enable you to develop native-only applications. Android's primary runtime remains the Dalvik virtual machine.

Correct. As I pointed out above, the NDK actually is just a framework for building native libraries that standard dalvik apps then call. However, my point was that the libraries themselves (the products of the NDK) cannot access or invoke the Android framework. There is a pointed distinction.
At least this could mean the beginning of some video codec porting to the G1's hardware. Be nice to be able to actually make use of my video collection without having to reencode everything.

That is probably what the NDK is perfect for. It's CPU intensive stuff, already written in platform independent C/C++ that can then be called from within a nice Androidy UI.
So they basically added JNI to the SDK...

Android Games WILL be improved thanks to NDK r3 and OpenGL ES 2.0
Developers on the Android platform have already been pushing the boundaries of Android gaming. Even Quake 3 has been seen running on the Android platform. Things can only get better with today’s announcement.
The Android Developers Blog today announced the availability of the NDK r3 that will let android developers directly access OpenGL ES 2.0 features.
Applications targeting Android 2.0 (API level 5) or higher can now directly access OpenGL ES 2.0 features. This brings the ability to control graphics rendering through vertex and fragment shader programs, using the GLSL shading language.
A new trivial sample, named “hello-gl2″, demonstrates how to render a simple triangle using both shader types.
With access to these enhanced OpenGL ES features game graphics should be greatly improved and we should start to see an awesome future for Android gaming. Obviously, we still need developers to take advantage of the new API and have the hardware powerful enough to use it, but everything is getting real close to serious gaming on Android.

What is the Android NDK?
The Android NDK is a toolset that lets you embed components that make use of native code in your Android applications.
Android applications run in the Dalvik virtual machine. The NDK allows you to implement parts of your applications using native-code languages such as C and C++. This can provide benefits to certain classes of applications, in the form of reuse of existing code and in some cases increased speed.
The NDK provides:
* A set of tools and build files used to generate native code libraries from C and C++ sources
* A way to embed the corresponding native libraries into application package files (.apks) that can be deployed on Android devices
* A set of native system headers and libraries that will be supported in all future versions of the Android platform, starting from Android 1.5
* Documentation, samples, and tutorials
This release of the NDK supports the ARMv5TE machine instruction set and provides stable headers for libc (the C library), libm (the Math library), OpenGL ES (3D graphics library), the JNI interface, and other libraries, as listed in the section below.
The NDK will not benefit most applications. As a developer, you will need to balance its benefits against its drawbacks; notably, using native code does not result in an automatic performance increase, but does always increase application complexity. Typical good candidates for the NDK are self-contained, CPU-intensive operations that don't allocate much memory, such as signal processing, physics simulation, and so on. Simply re-coding a method to run in C usually does not result in a large performance increase. The NDK can, however, can be an effective way to reuse a large corpus of existing C/C++ code.
Please note that the NDK does not enable you to develop native-only applications. Android's primary runtime remains the Dalvik virtual machine.
Contents of the NDK
Development tools
The NDK includes a set of cross-toolchains (compilers, linkers, etc..) that can generate native ARM binaries on Linux, OS X, and Windows (with Cygwin) platforms.
It provides a set of system headers for stable native APIs that are guaranteed to be supported in all later releases of the platform:
* libc (C library) headers
* libm (math library) headers
* JNI interface headers
* libz (Zlib compression) headers
* liblog (Android logging) header
* OpenGL ES 1.1 and OpenGL ES 2.0 (3D graphics libraries) headers
* A Minimal set of headers for C++ support
The NDK also provides a build system that lets you work efficiently with your sources, without having to handle the toolchain/platform/CPU/ABI details. You create very short build files to describe which sources to compile and which Android application will use them — the build system compiles the sources and places the shared libraries directly in your application project.
Important: With the exception of the libraries listed above, native system libraries in the Android platform are not stable and may change in future platform versions. Your applications should only make use of the stable native system libraries provided in this NDK.
Documentation
The NDK package includes a set of documentation that describes the capabilities of the NDK and how to use it to create shared libraries for your Android applications. In this release, the documentation is provided only in the downloadable NDK package. You can find the documentation in the <ndk>/docs/ directory. Included are these files:
* INSTALL.TXT — describes how to install the NDK and configure it for your host system
* OVERVIEW.TXT — provides an overview of the NDK capabilities and usage
* ANDROID-MK.TXT — describes the use of the Android.mk file, which defines the native sources you want to compile
* APPLICATION-MK.TXT — describes the use of the Application.mk file, which describes the native sources required by your Android application
* HOWTO.TXT — information about common tasks associated with NDK development.
* SYSTEM-ISSUES.TXT — known issues in the Android system images that you should be aware of, if you are developing using the NDK.
* STABLE-APIS.TXT — a complete list of the stable APIs exposed by headers in the NDK.
* CPU-ARCH-ABIS.TXT — a description of supported CPU architectures and how to target them.
* CHANGES.TXT — a complete list of changes to the NDK across all releases.
Additionally, the package includes detailed information about the "bionic" C library provided with the Android platform that you should be aware of, if you are developing using the NDK. You can find the documentation in the <ndk>/docs/system/libc/ directory:
* OVERVIEW.TXT — provides an overview of the "bionic" C library and the features it offers.
Sample applications
The NDK includes sample Android applications that illustrate how to use native code in your Android applications. For more information, see Using the Sample Applications.

well if the rumors about every single android device being upgraded to 2.1 in the US are true then id think so. we already have partial 3D working, so i think with this release the devs will be able to make it work
Except the chip in the G1 is not built for 2.0.
IMHO, if you'll see 2.0 drivers on the G1 (or Hero) it'll be software. But I'd love to be proven wrong, so please do.

from what ive read on androidspin and phandroid, some phones will receive a slimmer 2.1 that doesnt support lwp OTA. some devs have found ways to use software libs and kernel edits to use partial 3D acceleration in some 2.1 roms. Firerat and Case_ managed to get 3D and Youtube HD working on Canon's Roms. The next OpenEclair should have fully working 3D, lwps, and video according to wesgarner, so i think that this upcoming release mentioned in the article will provide more tools for our devs to use on the G1.

This doesn't at all in any way say that we're getting 2.0 drivers for the G1. All it's saying is that phones with 2.0 will be able to directly access ES2.0 functions.
Which, really, has absolutely nothing to do with the driver issue we face. Unless you can point out something I missed.

sorry i probably misunderstood the article =/
im still not very experienced with android development, i thought this would help the devs a little bit with getting 3d working (since theyre already doing that without official drivers)
I did indeed get a humongous boner on reading this earlier. It was enhanced by 3D.
My favorite part about this is the new ability to use openGL in apps! That means the entire face of our OS is going to change.
...and speaking of OS... Qualcom/htc just released a new radio for the G1. The G1 To this day holds over 50% of the android installed user base. There is no doubt the G1 will live beyond 1.X
bleah writing games in opengl es 1.0 was hard enough...

the binary still needs to be available

the open source one
/system/lib/egl/libGLES_android.so
and the proprietary

the quoted text in the OP is basically stating that an Android developer will now be able to mix in a little c/c++ to get direct native access to opengl es

What Chainfire said is that there is no hardware support for OpenGl ES 2.0 in msm720x chips. (refs here, sorry couldn't find official spec datasheet).
So even if 2.0 is supported, it will only be through software drivers implementation, which means really slow rendering.

Thats right.
But most Games will probably/hopefully still be written for OpenGL1.1. (Because of the userbase whatsoever)
For a start, but to focus at the future, too bad, the G1 will get old sooner
Hi,
It was not until I started the adventure with Android, but right now I would like to learn a few issues. Suppose that some Chinese have a tablet. Does the official library for Android (Java), there is a possibility of getting into the hardware and GPIO lines suppose to control whether the PWM? If not, you could ask for a sketch of the problem, how to write a library yourself suitable for such things? How do I know, the kernel of Android is simply Linux. Is the structure of the Android file system is similar to classical linux distribution? If so, you can access through the Android API again, to all the common files in the / dev, / sys or / proc? I know there's NDK, which sooner this would be suitable, but unfortunately, terribly lame documentation. Due to the fact that even a little the market is functioning Android application developers write programs mostly in Java, so I thought that such issues are already in library. Thanks for help
This is something that is driving me crazy, shouldt be MIPS Android SDK and NDK be compatible with any source maded for the ARM version?
First thing i noticed with this Ainol Novo 7 Basic was that, the small amount of compatible apps, none of the better apps are compatible.
No: Netflix, Skype, Android Terminal Emulator, MX video Player, Chainfire3D, any mame32/nes emu, a working barcode reader, connectbot, adosbox/qemu, opera or any other browser. and the list goes on.
I wonder why, i trought devs will want the larger amount of users as posible.
For the record, i just got Android Terminal Emulator working in my Novo 7 Basic, i had to:
1) Download Term source code
2) Download MIPS Android SDK, NDK, Apache ANT, Eclipse with ADL, cgywin (to compile NDK libs)
3) Import Term project to eclipse
4) change the target build to android-12
5) change Aplication.mk to "APP_ABI := mips mips-r2"
6) build ndk-libs for the app
7) build the project with eclipse
And i know nothing about programing for android, just c/c++
Best guess that anyone will probably give you is that the majority of devices out there running Android are ARM based, but as that changes, the number and quality of available apps should improve.
There is a HUGE obstacle to overcome however. Not many people are going to buy a device today based on what might run on it months from now, especially when there are devices out there that will run it now, and many of those that do purchase a MIPS based device consider it a mistake and end up returning it.
It is not possible to offer two different version on the market and i don't think it is possible to restrict the apps to a specific architecture.
Are the number of MIPS devices really rising? The android market doesn't really seem to be ready for that. It would mean even more app versions devs would have to consider.
Which apps work and which don't?
Maybe those using native code, compiled with NDK don't work, as those routines are compiled specificly for ARM.
Don't take my word for it though, just some thoughts.
its not possible to get 2 different versions on the market.
Rumor has it that the problem is frequently a development oversight and that it's related to omitting some important MIPS related files from the package build.
I imagine that it can also be related to poor programming practices and also programming for optimized code.

As far as I know, Market supports device specific apk's nowadays, which would make it possible to have an mips apk...
http://developer.android.com/guide/market/publishing/multiple-apks.html
Altough the proccess is not trivial, it is not that difficult either, just minor changes to the manifest and filter the apk for Native Platform...
Also, it would be possible to compile it for all devices that the current NDK supports, by using the latest revision of NDK (as of November 2011):
http://developer.android.com/sdk/ndk/index.html#overview
You just need to add:
APP_ABI := all
Click to expand...
Click to collapse
to the makefile and it should now be compatible with all processor architectures that NDK supports....
So, now there are means to easily support different processor architectures, but, don't expect quick adoption of it, as, unfortunately, this depends entirely upon developer will to change some of its project settings and/or publishing way (it is entirely possible, now, to have a single apk for all platforms)...
Unfortunately, right now, and I would dare to say, in the next 6 - 8 Months, I would not expect this to change much... Altough the official NDK has support for multiple devices, it still doesn't incorporate the MIPS abi, which is not official, and thus, it is not possible to declare that an APK for a native MIPS device as well...
Hopefully MIPS devices will grab a nice piece of the Android devices and then "force" Google to officially support those devices. I believe that it is possible to grab the latest unoficial NDK and use it with APP_ABI all and publish it to the Market, but, as of today, is mostly something recent and that few (if any) developers support (remember, this possibility came with November's NDK, I'm not even sure if MIPs NDK is already up to date with Google's November NDK), so, I would dare to say, MIPS devices are not in a good position right now (even x86 devices, which have official support, are not...).
I have a MIPS based tablet named "MIDI Japan MD-785IP" that is quite nice but is making me sad with the lack of some softwares and in special, lack of ROMs to it. Apparently I am the only person in the internet that have one

Hello,
Have you shared that MIPS compatible Android Terminal Emulator?
Thank you
Sure... and here is connectbot too.
Ive attemped to recompile adosbox too but the source code and makefiles are just a big mess and no documentation provided.
And that is another problem, poor documentation in open source projects.
BTW, Market has to have some way to know if a app is for arm or mips, since market on basic only shows up compatible apps.
Also, its no enoght to just incluide the "mips" folder along with "armabi" with all mips compiled .so files inside the libs folder? because is that all what it takes, unless the app is using binaries.
And im agree that google has most of the fault for not incluiding mips supprt in his NDK, the mips one can compile for both.
I wonder what will happen when intel medfield will came out...
I am in an even worse position - I bought 2 NOVO7Paladins - one for the g/f. I had to get one for myself, because I know I will be 1st line support
So, I have a MIPS cpu (with reduced software availability) and also ICS which further reduces app compatibility.
Apps which I consider essential (Samba server, VNC Server, Angry Birds Seasons....) are not available, so l'm currently installing eclipse, JDK, SDK, NDK on a linux box to try to rebuild stuff - it has been many years since I last had to get my hands dirty with code.
I know I have a steep learning curve ahead, but I'm sure it will be many months before there is a significant increase in app availability. I understand though, that if developers have written native code for ARM, they won't be in a hurry to port that to a minority cpu. It is way easier for new apps to be built with different architectures in mind.
Thanks Shivansps, I had been looking for a terminal - I had given up and was trying to get telnet working - a last restort. It was either that or carry a laptop around with me to use ADB
Now, all I need is to get the MIPS ABI to appear in Eclipse AVD setup... (oh, and learn how to code for android )
i dont use Eclipse or SDK myselft any longer, what i do is just recompile shared libs with mips NDK and include the new "mips" folder intro the libs folder of the original .apk file, then re-sign the apk with one click signer.

Would you please test MapsWithMe on it? It's offline world maps based on OpenStreetMap.
We've built apk for mips and x86 architectures but doesn't have any devices to check if it works.

Hello,
I am posting to begin a thread regarding the native compilation and execution of OpenCL code on an ARM Android device, namely the HTC One M8.
I have used the app Linux Deploy to install a Debian desktop environment alongside Android, sharing the same Linux kernel but supplying different runtime libraries. Additionally, I have installed gcc/g++, Code::Blocks, and the OpenCL ICD and header files necessary to compile a native binary.
My intent is to continue developing a graphics render algorithm, but if I can get a working Android binary from g++ on a GNU toolchain, I would be happy to share generalized source code so that others can do the same with some simplicity.
Currently, I have success compiling a binary with shared libraries for GNU/Linux, but it does not detect the OpenCL devices on my system. I tried statically linking my application, but it refuses to link OpenCL statically.
The way I see it, there are two ways to solve my problem:
1) I assume Debian cannot see devices due to a driver issue, but I could be wrong, and I don't believe appropriate GNU drivers exist at this time. (Please correct me in a response if you know this to be false.) I have talked briefly with some of the folks from the Freedreno project, and it seems the OpenCL compiler is the biggest missing piece between the driver and the hardware. Unfortunately, I do not know if a working driver would even solve the issue in my case.
2) Compile binary with Android shared libraries. This may be most easily done with Eclipse, but I prefer Code::Blocks, so if the libraries could be linked in, then it may be trivial to change IDEs. I suppose it depends entirely on how the NDK handles compilation.
Option 2 is most likely the best course of action. I intend to publish my progress in milestones. Discuss.

Answer to your question = Mint 17.1 Works for me and this should be in general as this has nothing that you created.
