Any chance to get this into the Processing "Contribution Manager"

[mxa]

This library would be nice to be made available as an easy install through the Processing Contribution Manager. Is that possible?

[b2renger]

Well I defintely agree with this. Considering that no audio library for processing is working both for desktop and android it would a great addition to the collection of available libs for processing.

As it goes the latest versions of the build works on linux and mac, but not on windows and I think the compatibility with android is also broken. So to get this in the processing contribution manager we would need to fix it for windows and android.

I hope to be able to work on this soon, but if anyone is also up for it let's discuss !

Hello All,

I would really love to get this working and try to maintain it. I'm pretty much at ease with processing and pd, but I'm probably lacking some basic knowledge on how to create a cross-plateforme lib for desktop and android with processing, and with jni.

@nettoyeurny could you provide me some information on why this was never released ? I dug around and tested it and found out that the android mode was broken as well as the windows version.

Concerning the windows version I'm pretty sure that recompilling the dll would be enough.

Concerning android the project builds but crashes on launch with this error :

Would you have any pointers and places to look at or stuff to read to help me get started ?

The stack trace refers to a theming problem, which seems unrelated to the lib:

[b2renger]

hum right, I'll try to investigate. It's probably linked to the way processing packages the project for android. But it's weird that I don't get this error when trying to compile other examples from other libs.

[b2renger]

@joebowbeer I rebuild the lib with the "make javalib" command and replaced the libpd.jar by the one build with this command.

the example still works on mac but now I get this error when building for android :

it looks like it doesn't find a native extension for android, any idea where I should look to fix this ?

[joebowbeer]

@b2renger Some work is needed before pd-for-android works smoothly with processing. See below. Also, your apk will need to be built with gradle and should depend on pd-for-android as a library dependency. See examples in pd-for-android.

Pasting a TODO list that @nettoyeurny sent a while ago:

• The basic mapping of the libpd API to Processing's idiom is essentially done, I think. I haven't heard any feedback from actual users, though, so I'm not sure whether the library feels right to someone who's truly at home in Processing. An API review would be useful.

• I don't think there's a way to have Processing package raw assets for Android. I worked around that by adding a method that unpacks a tar resource so that libpd can read it. The creation of a tarball doesn't really sit well with a Processing workflow, so I'm wondering whether there's a better solution.

• Release engineering! Right now we manually collect whatever binaries we happen to have, copy them to the appropriate folders in the Processing library, and hope that they won't age too badly. This really ought to be automated, but it would probably be a big job.

[b2renger]

@joebowbeer thanks for the feedback, I'll look into it and chime back in here.

To build for android, I was able to get rid of the first Theme.AppCompat-error by updating the AndroidManfest.xml in the example-directory:

<?xml version="1.0" encoding="UTF-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="1" android:versionName="1.0" package="">
    <uses-sdk android:minSdkVersion="15" android:targetSdkVersion="28"/>
    <application android:debuggable="true" android:icon="@mipmap/ic_launcher" android:label="" android:theme="@style/Theme.AppCompat">
        <activity android:name=".MainActivity">android:theme="@android:style/Theme.AppCompat.Light.NoActionBar"&gt;<intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
    </application>
</manifest>

However, I too got stuck at the missing libpd.so error.
The pd-for-android direction pulls me into the rabbithole I was trying to avoid by this repo :)
Anyways, just wanted to let you know there's interest for this repo 👍
