Ah, yes, I'd forgotten Chrome now runs Android apps.

Given that Chromebooks are by far the fastest-growing device type in 
EDU, if it were up to me I know what enhancement I'd have the engine 
team working on next...

devices they can't run on, but I have no data on that.



I believe all the Chromebooks have Intel chips. This includes the 2016+ 
models with Android app compatibility. The rollout of the compatibility 
layer to Chromebooks is slow but there's an impressive list of planned 
(as in don't hold your breath) hardware here:

...and as noted here,

This leaves me wondering which percentage is larger:

How many Android apps like LiveCode are written in C++ rather than Java?

-vs-

How many Android devices have an x86 processor?

My hunch is that there are more C++ apps on Android than there are x86 
devices they can't run on, but I have no data on that.

Hi Richard et al,

Actually, LiveCode was not rewritten in Java, nor compiled to Dalvik/ART 
bytecode.
The engine for Android is largely written in the same C++ as for the other 
platforms.
And then compiled to native ARM instructions for the specific Android variant 
of Linux.

Most Android apps are written in Java, and occasionally tap into native code 
via the Android Native Development Kit (NDK).
Android NDK is the platform-specific implementation of the Java Native 
Interface (JNI).
Android has multiple Application Binary Interfaces (ABIs) to support various 
architectures.

ARM Android apps that don't need access to native code can run 'as is' on x86 
Android devices.
Those that do need native code, will have to compile separate builds (and may 
bundle them into a single 'fat' APK).
Or they have to rely on the ARM-on-x86 emulation feature named Houdini.

So LiveCode is a bit of an outsider, as the apps it produces spend little time 
in the Dalvik/ART virtual machine.
All scripts run in the native portion, and events are funneled from the VM into 
native code to be handled there.

All this to say: if we want native x86 Android apps, then the LiveCode team 
will have to crank up the compilers again...

But can you run an Android APK made with LiveCode on an ARM Linux OS?

LC-built APKs expect things the Android OS packages provide.

Similarly, you can use the Raspberry Pi build of LC to deploy to ARM 
devices running Linux ARM distros packaged for that hardware, since that 
LC engine is compiled for the packages expected on Raspian and 
Raspian-like systems (e.g. Debian ARM, Ubuntu Core ARM, etc.).


The CPU architecture is only part of a complete breakfast.  Delivering 
an application to that CPU will require integration with the OS it will 
run under.




As much as I enjoy having my Rpi2 and RPi3, I've only found one 
practical use for either (in progress; will probably write an article 
about it for MagPi when it's done).


For IoT they're wonderful, but for anything that needs a GUI even the 
RPi3 isn't very satisfying for someone used to ordinary desktop 
performance.  And if a 100 Gb Ethernet port weren't bottleneck enough, 
sharing the controller with the USB 2 (yes, 2) port doesn't help.


As wonderful as it is to get a mobo for US$35, by the time you get a 
case, power supply, MicroSD card of reasonable size, and any other 
add-ons you might need, you're up to about $80.


Still not bad, but for just twice the price you can get more than 4 
times the computing with one of the Atom- or Celeron-powered NUCs or 
Compute Sticks.


And with a NUC or stick you get the rest of the full x86 ecosystem, 
which includes being able to run the latest and greatest LC IDE on it 
quite comfortably.


There's a place for RPi, but there are more places for NUCs and sticks. 
And with so many knock-offs available, NUC and stick options below $200 
abound.

There's more to Linux than the kernel.

The LC engine for Linux has fewer dependencies than most (it amazes me 
just how deeply reliant some apps are on very specific system 
configurations), but it does expect a reasonable baseline of GDK and 
other elements found on nearly all Linux desktop systems, which I 
don't believe are part of Android.


So while we can build for a very wide range of Linux distros, Android 
is Linux-based (as in, it uses the kernel and a handful of other 
packages) but is not a Linux distro per se.


I don't believe Android includes what the LC engine expects to find in 
order to run.


If that is so why can LiveCode make standalones that run on ARM Android?




I had thought one of the reasons Android uses the Dalvik and ART VMs 
is because they're VMs, separating the APIs from processor architectures.


If so, then the LC engine for Android is bytecode rather than machine 
code, and as such should run on either processor architecture, no?

Does it run arm-emulation automatically or do we need to warn it?

The parts I use that are processor-intensive are running in the browser widget, 
which I assume runs on both architectures.
