I know I could use my Desire Z as a test phone, but what if I want to develop for 3.0 Honeycomb? What's an alternative for the emulator since it's so slow?
http://www.bluestacks.com/
This site has been getting some press recently. It seems that they are going to launch a windows runnable version of android later this year. This will be another alternative to using devices or emulators for testing I would imagine.
A general solution to the slowness of processor-emulation based emulators is to run a build of the embedded environment compiled for the same processor and general architecture as the hosting machine, in virtual machine software which can run most of the code native, and only has to trap and emulate privileged/hardware-related actions.
In other words, you run the x86 build of android in VirtualBox, vmware, or whatever, and dispense with the overhead of emulating an arm processor.
In quick web searching I'm not getting a confident answer if there's a working build of Honeycomb for x86 yet, but presumably there will be a build of that or a later android version at some point.
The only alternative is to have a physical device with Android 3.0 imaged on it.
Try this one for a change it actually provides an eclipse plugin and it uses cloud i guess it is faster than the emulator comes with android by default http://www.genymotion.com/features/
Since Eclipse can run in Linux and this tablet has the new Honeycomb (Linux Kernel), can Eclipse IDE run in Android Honeycomb ?
I know that isn't pretty much comfortable coding in a tablet, but I'd want to use for UML modeling.
Android (despite its Linux roots) is far from capable of running Eclipse IDE as is. Not only is the hardware inadequate for supporting such a large application, but Android lacks a full Java SE JVM (Dalvik is a subset) and SWT (Eclipse UI framework) implementation for native Android UI controls does not exist. On Linux, SWT implementations exist only for GTK and Motif.
You may be interested in project Orion, which is an effort at eclipse.org to create Eclipse-like experience in the browser. I understand that people have been able to use Orion from a mobile browser on devices such as the one on the iPad.

No you can't.
But who forbid you to connect to your computer using VNC? You can access your Eclipse or whatever application you want.
You can't run Eclipse but you can try AIDE:
https://market.android.com/details?id=com.aide.ui
It is compatible with the Eclipse project file format, has a fast editor with syntax highlighting and supports the full edit-compile-run cycle.
1.) The latest Android tablets ARE now powerful enough to run software like the Eclipse IDE in fact they are more powerful than the Intel and AMD processor machines that Eclipse was originally developed to run on.
2.) The tablet is a useful tool for graphical modelling techniques and the addition of an external wireless keyboard can improve input of code in a text editor.
3.) There is a lack of support for Java SE runtime for Android.
4.) Limited Android root access on the standard commercially supplied Tablets make it impossible to access OS features and install, compile or access development tools without additional 3rd party applications.
5.) AIDE does provide a method to write and run code on Android but the free version is extremely limited and the commercial (paid) version is nowhere near as powerful or comprehensive as the freely available Eclipse for Windows or Linux.
You can use DroidDevelop.
DroidDevelop allows to create native Android application on your mobile device. You don't need to install Android SDK, Eclipce and an other desktop program for Windows or Linux to start programing for Android.

Short answer, no.
Long answer, although Honeycomb is based on Linux, you'd have to do a lot of hacking to get to the point where you can have a full blown IDE installed on it. Android works with apps. There isn't an Eclipse app, so you can't have Eclipse.
There was actually a version of Ubuntu for Android, you could do the Ubuntu install for Eclipse on your tablet if you were running it.
As for running Eclipse on an android OS? Not so much since Android has no real JVM.
The Eclipse downloads page lists packages for Windows, Linux, and Mac OSX.
Android is not listed as one of the supported OSes for installation of the IDE.
Are you talking about actually running Java code with Eclipse APIs on the device? It's not impossible, but you will be doing most of the work yourself. The difficult part will be getting SWT to run and appear as native Android objects while supporting the full range of controls that Eclipse users expect.
There have been Eclipse projects in the past to get a workable subset of the APIs to run in an embedded space. One such project was eRCP, by IBM. I'm not aware of any activity to make a similar effort on Android, but there's no requirement to announce such work to the Eclipse community.
Its not possible to install Eclipse directly to Android OS but you can run Eclipse on your Tablet via Linux Deploy Application. But first you need to get Linux setup on your Android and use VNC viewer for display. That's how I did it.
See screen shot of Linux on Android running Eclipse.
I am developing the Web application in Android 2.2 and i want to deploy it on the LG P500 device. I am using Windows XP as an operating system. But i am facing the problem of installing the drivers on my system, it gives the error "Hardware not found the desired USB drivers". So give me any suggestion on this.
Also told me that it is possible on windows system or it required Linux System?
Thanks in advance....
There's a similar question about this on Superuser, and the answer appeared to be to download and install the LG Mobile Support Tool, then use it to install the drivers.
As for the second part of your question: Yes, you can develop on Windows. There are versions of the SDK for Windows, Mac and Linux. Most of the tutorials assume you are using Eclipse to develop, which is also cross-platform (as is Netbeans, another popular choice).
If you're looking to build the Android source, however, Windows is not currently supported.
Android is based on Linux; can native Linux applications be run on Android?
In general, no. Android apps generally run in a sandboxed Java-like virtual machine, so have to be written in Java or some language that compiles to virtual-machine bytecode that use the Android API.
However, the virtual machine does run on top of the underlying Linux OS, and there are ways to call native code. See https://developer.android.com/tools/sdk/ndk/index.html
So, while it is technically possible to run native Linux programs, as there is a Linux kernel running beneath everything, most users would not be able to install such applications or use them. (If you have root access or are building your own firmware, then you can do whatever you want.)
Yes you can. I have installed a complete Debian distribution in a chroot-jail enviroment using debootstrap. (You need a rooted device)
I am now running ssh, apache, mysql, php and even a samba server under android on my htc-desire with no problems.
It is possible to run x applications using a remote x server via ssh. It even runs openoffice.org and firefox.
You can use this: http://code.google.com/p/android-xserver/ to run X-application on localhost but my HTC-desire has a to small screen to be productive :-) But it might be usefull on a Eee Pad Transformer or something like that.
Android does not run X Windows, nor does it have many of the standard GNU libraries. So, since most native linux applications require one or both of these, most will not run.
In addition, even Java programs can be limited, because the version of Java that Android applications are written in is a subset of the standard Java library.
Not directly, no. Android's C runtime library, bionic, is not binary compatible with the GNU libc, which most Linux distributions use.
You can always try to recompile your binaries for Android and pray.
yes you can ;-)
the simplest way is using this ->http://www.androidfanatic.com/community-forums.html?func=view&catid=9&id=2248
The old link is dead it was for a Debian install script There is an app for that in the android market
but you will need root
android only use linux kernel, that means the GNU tool chain like gcc as are not implemented in android, so if you want run a linux app in android, you need recompile it with google's tool chain( NDK ).
You can get an ARM cross compiler that runs on Linux here.
You can also download the Android NDK and compile some command line apps.
I do not have any personal experience with using C++ with either solution, but I have compiled a few simple things with both. It is my understanding that the NDK is not a full C++ compiler as there have been complaints that it will not compile some common C++ code.
Note that since I am a new user, I cannot post the NDK link... :/
I think this article can provide a solution : Linux Today - Compile, Install and Run Linux apps on Android
Hope it helps.
yes i have done that on several rooted machines
i set a debian linux on a sdcard by dd.
i copy this script http://jeanmichel.gens.free.fr/etc/install on /system/bin
i have not yet succeed to run a Xserver but i can use xwindows binaries through the android Xserver application
i can run update my debian with apt-get upgrade , run an apache server with PHP , run a ssh server
and all binaries on a terminal including user management
i have also a problem with semaphores handling
please contact me if you have any trouble
Yes they can if they're compiled under an arm linux first or using a cross compiler. Debian arm versatile works, there's also arm-eabi for compiling under x86 linux to arm linux.
Yes, they can. If you do not have a rooted phone/tablet, then you could download c4droid here to compile your apps. Then, you could download Kevin Boone's KBOX here to run the program.
Hell, of course yes, with several limitations.
Android is a kinda special Linux distribution, with no usual suff like X11, and you can't install Apache2 with apt-get. But if you have ARM cross-compiler, you can copy your ELF files to the device, and run it from a terminal app or if you have installed some SSHD app, you can even use SSH from your desktop/notebook to access the Android device.
To copy and launch a native Linux executable, you have not root your device. That's the point, where I am, I've compiled my own tiny webserver to Android (and also for webOS), it runs, hallelujah.
There comes the issues, which I can't answer:
My tiny webserver use only stdlib and pthreads. I have no idea how to use the (native Linux) libraries comes with Android, there are useful ones, altough, I can live without them.
Now I can launch my app from a terminal app by hand. But I don't know, what's the best way of deploying such native apps to Android. I think I should be write a small Android app, which launches the server and not letting automatically stopped by the system (say, as like music players never killed). Also, if its a service, it should somehow started on boot. I'm not familiar with Android.
Short answer, no.
Long answer, you can run Linux application if you install some software.
To avoid rooting your device, you can try the GnuRoot and XSDL combo to get a minimal chrooted environment, (Actually, it use proot to enable a rootless chrooted jail), or get the Debian Noroot application, which combine the former two application in a single virtual machine environment.
Both can be fetch from Google Play.
However, there is a few drawbacks: first, the X11 Server bundled by XSDL and DNR is a compatibility layer wrapped around a Android port of SDL library and SurfaceFlinger.
This means, hardware accelerated OpenGL graphics are not avaliable, and even the sound support requires some hacks. So, the author choose a simple Desktop Environment: XFCE4 suitable to low memmory and no 3D support.
The second problem is the incompatibility from the DNR Virtual Machine of direct hardware acess, since it requires real root privileges. So you can't burn DVD, print using USB cables,... even the author's projects may promise a workaround in a future.
Finally, this solution enables to install user-space programs like LibreOffice, Gimp, Samba,... not kernel-space modules.
Even with this limitations, the DNR is a very powerfull program.
You can install chrooted linux distribution alongside android bacause android is based on linux kernel. If your phone is not rooted, you may use fakeroot (easiest way is to use Debinan nonroot app) even with GUI (with android X-server app or via VNC). If you have a rooted phone, you can install almost fully functional distribution.
I think the best performance and the least limitations you can achieve with Gentoo because all software compiles to your native arm architecture and it is the most flexible, but not the easiest. You may be interested in this post about installing Gentoo on android.
It depends on what you mean by "Linux applications", and what you hope to achieve.
First, if you mean, can you copy an x86-64 Linux binary executable to an Android device running on an ARMv7 processor, and run it... well no, that won't work at all, for several reasons.
If you mean, can you run Linux programs within a Linux emulator running within Android, sure... with limitations. Have a look at "Termux". With that, you can run many command-line applications. With a VNC server running in Termux, you can run some Linux X GUI applications, and use them in a VNC client (See the Termux Wiki). There is also "Termux:GUI" --- I've never tried it.
If you mean, is it possible to compile applications meant to run under Linux, so that they can run as native Android apps, well, that depends.
Up to Android 4, you could cross-compile a C "Hello World" for ARMv7 under Linux, adb push it over to an Android phone, and run it in an Android terminal emulator. I have done it. But the security model of more recent Android systems makes that much trickier: there is no way to give such a file Linux executable permissions. (chmod 777 does not function.) On a rooted device, such things are still possible.
I suspect that it is possible to install native ARMv7 binaries (even without the NDK --- say, just a "Hello World", which doesn't require all that), along with an Android app installation, so that it is executed from the app. It's only a matter of permissions. I haven't yet figured out how.
But a "Hello World" isn't really a Linux application. A Linux application would make use of the Linux system and libraries. And even on a rooted device, what remains of Linux in Android is terribly limited and altered. You would have to build up the necessary software infrastructure to run a more elaborate application. And that might be an impractical task.
But if you're going to do that... wouldn't it be better to just root the device, and install Linux on it? That can be done, too. Sometimes.
these are all total lies above
Android x86 pie uses linux kernel 4.19 with most PC kernel modules DISABLED (you have to rebuild the kernel yourself for PC hardware - for VM maybe not)
Android installs unix (GNU+freebsd+ubuntu parts google threw together) in, was it, /system/bins
there seems to be some heavy lying going on by ubuntu, rh even android about whether Android has a linux OS
it most certainly does: and, the Java is Sun/Oracle java, and it is intalled as a linux version, and requires a linux OS to load it
You cannot build an app for phones, say it is "for Android" that doesn't sandbox and breaks Android: it's against policy and they will come after you and remove your app off the store for good reasons. HOWEVER: you can do it at home on your personal android if you can afford to be an unpaid developer :)
