Hi All,

For those using Android Csound, I am currently looking at the build.
The state of it is:

1. Compiling Csound with NDK r11c  (an older version, but one I've
used a couple years now), I can compile everything but the Ableton
Link opcodes.

2. Compiling with NDK r16 (the most recent released), I get crashes
from clang while compiling csound. The message reports it happening
while compiling for armv5, which leads me to the following.

Right now we are compiling for armeabi and armeabi-v7a. In NDK r16,
armeabi has been deprecated and it will be removed in NDK r17 [1].  I
am going to move forward with removing armeabi from our build and to
add in arm64-v8a (64-bit ARM).

Even when we first built Csound for Android, running Csound on armeabi
(arm v5) was somewhat useless as it was pretty much unusably slow.  It
was useful for a while for the purpose of running Csound on desktop
Android emulators, but that was about it.  Additionally, I think it's
a bit of an oversight not to have arm64 support at this point.

I'm going to look into this today and, if building can work out with
r16, I will post a test build today.  At that point, it would be good
to get some testing by others, particularly arm64.

Thanks!
steven

I'm fine with removing armeabi.

Thanks for that feedback. I'm not too, too worried about removing
armeabi (and doing so seems to have fixed clang crashing here!), but
I'm thinking through what we did when we put first put together Csound
on Android and I'm trying to remember if we didn't hard code some data
type sizes somewhere.  That'd probably manifest into unexpected
behavior for the arm64 build.

Update:  I've made the changes for:

* Remove armeabi, add arm64-v8a
* Update gradlew to use 4.3.1
* Update projects for use with Android Studio 3.0.1 (Latest stable
version of Android Studio)

I've uploaded a build of Csound for Android here:

http://kunstmusik.com/csound-android-6.10.0-beta.zip

I ran the Csound Examples project on my Moto G4, which I believe has
an arm64 CPU. I was able to get realtime output, but some of the
examples that asked for audio input did not work.  (I suspect it is a
permissions issue; if anyone has experience here please do chime in.)

What would be great at this point:

* Please test this release out with the supplied Examples project.
* Please test the CsoundAndroid release out with your own projects.

I have also pushed the changes I've made to the android studio and NDK
project files to Git.

Thanks,
steven

Hi Jacques,

Thanks very much for confirming the issues I saw and for bringing up
Oboe. Our Android build and Csound SDK needs updating at some point
(e.g., when we put it together, CMake was not supported with NDK like
it is now: https://developer.android.com/ndk/guides/cmake.html).  I've
filed an issue on Csound's tracker
(https://github.com/csound/csound/issues/887) to keep track of this so
we remember to look into Oboe when it develops further.

I think for 6.10, we should limit the scope to just getting the audio
recording to work. I'll look into this a bit today.

Cheers!
steven

I looked into this and determined it is related to trying to open
stereo input and OpenSL causing a failure, at least on my device.
Switching to nchnls_i=1 allows the project to open but there was
another bug found.   I've reported this to the dev list and await
feedback/fixes.
