Fiddle / pd externals not working on arm64-v8a devices

[deepkanwal]

I have a simple patch using fiddle which looks like this:

However, when I attempt to use this patch with pd-for-android, I get the following error:

The patch works fine when running via Pure Data.

I am using PDService, which from what I understand, will handle installing standard externals.

Here's a link to the activity in which I'm doing all my pure data logic right now: https://github.com/deepkanwal/pure-data-fiddle-test/blob/master/app/src/main/java/com/deepkanwal/fiddletest/FiddleTest.java

Here's a link to a simple test project which I'm using to try loading fiddle: https://github.com/deepkanwal/pure-data-fiddle-test

Any ideas as to what the issue might be?

I just cloned the your test project on Android Studio 1.5 and it seems to work fine. Fiddle is created and seems to work. See the logcat print out:

Maybe try to clone your repository to a new folder and import it as a project in Android Studio? I can't explain it otherwise and also can't reproduce it..

Interesting, it actually works fine if I run in via Genymotion. The issue only occurs on my device (Moto X Pure - XT1575 running 5.1.1). Here's the full logcat from app start up.

Strange.. Did you manage to get any other libpd based app to run and produce sound on that device? Can you get the PdTest app to work on that device?

[deepkanwal]

Yes, PdTest does work on the device. Play back of the sine waves works and patch mic results in a distorted, high pitched sound.

[tkirshboim]

I really can't think of an explanation for this then.. If you can I would suggest trying another real device with the your test app. Another thing you could try is to edit the patch used by PdTest and add a fiddle object to it. If it fails to create it you'll see an error message on the screen. You could also add another object that does not exist just to be sure that you see the error message. Something like:

[joebowbeer]

I strongly suspect a permissions problem, given that Genymotion works and a real device doesn't.

By the looks of it, IoUtils.extractZipResource needs write permission.

[joebowbeer]

PdTest accesses a single .pd file, and so uses:

IoUtils.extractResource(in, "test.pd", getCacheDir());

[deepkanwal]

I am getting the seeing the same error message on screen when adding fiddle to the test.pd patch file in PdTest. Here's the patch file:

I'll try testing on another device soon.

[tkirshboim]

@deepkanwal Like Joe suggests - try then to add <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> to you AndroidManifest.xml and see if it fixes the problem.

[tkirshboim]

@mgsx-dev @deepkanwal @b2renger @joebowbeer I suspect this is related to the cpu type of the device. I could reproduce the issue that fiddle as well as the helloworld external are not created with PdTest when using an arm64-v8a device. Perhaps related to #33 ?

[tkirshboim]

referencing #14 because it's related @rayalu

[joebowbeer]

@tkirshboim The cpu type idea makes sense to me. Genymotion is x86.

[b2renger]

@deepkanwal @joebowbeer @tkirshboim

removing the '/arm64-v8a' folder from /libs enabled me to build on the nexus 9 with no issues. So we are indeed facing an issue related to cpu type in the building of externals.

[tkirshboim]

From @b2renger in the gitter chat room:

testing a little further, removing the 'arm64-v8a' folder, cleaning and building again resolved the issue on the nexus 9, so I guess if present it takes 'arm64-v8a' which seem to have a compilation issue, and if not it takes the basic 'arm' folder which works fine

I can confirm that if I remove arm64-v8a from the ABI that NDK builds the problem is solved on the arm64-v8a I use for testing. These should probably be done both for PdCore as well as for the pd external example in PdTest. I can do this later today and create a PR.

[tkirshboim]

@mrjohs - I thought I'd tag you here in case you're interested in following up on this issue as well.

[tkirshboim]

I released 1.0.0-rc4 version where this issue is fixed.
