How long does it take to compile android?

Q. ICS and later. I set up a VMware machine with access to 8GB of RAM (I got a total of 16GB) and access to 4 out of 4 cores and 50GB of HDD space.

How long will it take to compile android + a kernel?

A. Depends entirely on the power of your system. Which you didn't really include. You included how many cores - but not what type, and not the speed of your hard drive... both of which are important bottlenecks.


what does it mean when a tablet is OS?
Q. I just bought a tablet and I'm trying to identify it. All i know about it is that when it turns on it says "android tablet kernel OS" what does that mean? Please help.

A. It means that the operating system installed on the tablet is an Android-related OS.


What is the contact information for the manufacturing company of an Android 2.2 Tablet PC?
Q. I bought an Android Tablet 2.2
Kernel version: 2.6.32.6 jade@linux-server2 #207
Build number: V2.061
My tablet is not working correctly. The touch screen is not sensitive, you have to repeatedly pound the screen. And it WILL NOT charge. The red light stays on, and if you unplug it, it immediately goes black. Who do I contact or what do i do?

A.


Can an android tablet be booted from a usb port?
Q. I was wondering if I can run one of those light weight linux distro installed on a usb flash drive on one of those android tablets.
1) Is there a cheap tablet PC (under $200) that can be booted from a usb port?
3) Can I find a lightweight linux distro that has all the drivers for that tablet?
Thanks for replying.

A. First of all, Android is Linux. It's a custom Linux kernel with a special software layer on top. And the customizations to the kernel and the software layer sitting on top of it are pretty important for it to run on the rather specialized smartphone architecture.

Second, a kernel has to be compiled to run on a certain architecture. So you'd have to find a version of Linux compiled for an ARM processor. That's not much of a problem. Several distributions, including Ubuntu, have ARM kernels. But then you'd have to have kernel modules for the drivers of the smartphone hardware, which... isn't nearly as likely. And you'd probably need a specially-designed interface, since Gnome or KDE really wouldn't work on a 4-inch touchscreen. And all of that would also have to be specially compiled for the kernel. And that's before we start with the application software. And by the time you got all of that working... you'd essentially have Android.

And even if you could do all of that, you'd have to have some way of booting from the USB, which you can't since smartphone firmware boots the kernel directly, without any sort of bootloader like you have on a personal computer.

If you want Android to be more Linux-y -- whatever that means, since the Linux experience differs greatly based on the graphical interface (assuming you use one) -- you can install a terminal emulator and even the bash shell. If you play around with it a bit, you might be able to install some command-line Linux software. But even then, it wouldn't be terribly useful, given the limited ability to enter text on a smartphone.
