How am I supposed to add this library to my Android project? about porcupine

[kenarsa]

Take a look at how it is done in Android demo application please:

https://github.com/Picovoice/Porcupine/tree/master/demo/android

I get this error when running the application:

java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.[censored].[censored]-1/base.apk", zip file "/data/app/com.[censored].[censored]-1/split_lib_dependencies_apk.apk", zip file "/data/app/com.[censored].[censored]-1/split_lib_slice_0_apk.apk", zip file "/data/app/com.[censored].[censored]-1/split_lib_slice_1_apk.apk", zip file "/data/app/com.[censored].[censored]-1/split_lib_slice_2_apk.apk", zip file "/data/app/com.[censored].[censored]-1/split_lib_slice_3_apk.apk", zip file "/data/app/com.[censored].[censored]-1/split_lib_slice_4_apk.apk", zip file "/data/app/com.[censored].[censored]-1/split_lib_slice_5_apk.apk", zip file "/data/app/com.[censored].[censored]-1/split_lib_slice_6_apk.apk", zip file "/data/app/com.[censored].[censored]-1/split_lib_slice_7_apk.apk", zip file "/data/app/com.[censored].[censored]-1/split_lib_slice_8_apk.apk", zip file "/data/app/com.[censored].[censored]-1/split_lib_slice_9_apk.apk"],nativeLibraryDirectories=[/data/app/com.[censored].[censored]-1/lib/arm, /system/lib, /vendor/lib]]] couldn't find "libpv_porcupine.so"

I replaced my package name with [censored]

The log says it cannot find the shared object. I guess you have not included it in your app ...

Shared object? What is that?

Where do I get the "shared file" (I'm assuming the file is libpv_porcupine.so) and where do I put it?

[kenarsa]

.so files are here: https://github.com/Picovoice/Porcupine/tree/master/lib/android
you can use the android binding here: https://github.com/Picovoice/Porcupine/tree/master/binding/android
it gives you a ready to use AAR...

Where am I supposed to put the .so files?

Nevermind. It worked.
However, when I say the wake word, nothing happens. Here's my code:

try {
            manager = new PorcupineManager(modelFilePath, keywordFilePath, sensitivity, new KeywordCallback() {
                @Override
                public void run(int keyword_index) {
                    Toast.makeText(MainActivity.this, "Detected!", Toast.LENGTH_LONG).show();
                }
            });
            manager.start();
        } catch (PorcupineManagerException e) {
            e.printStackTrace();
        }

I get ai.picovoice.porcupinemanager.PorcupineManagerException: ai.picovoice.porcupine.PorcupineException: java.lang.IllegalArgumentException: Initialization of Porcupine failed.

How do I tell what's the issue? This also happens when I try to run your demo app.

[kenarsa]

I just tested the demo app and managed to build and run it on an Android phone.
have you looked into the logs?

The demo app doesn't even have the library imported properly. I don't know where you're getting at. I had to manually add the library to the demo app. I'm getting the same error. I got nothing from the logs. This library has 0 error reporting, if there's an exception, no matter what it is, it throws a PorcupineException.

Can you provide us with a .aar instead of having us do all of this to import the library properly?

[kenarsa]

I see. I am using the master branch of the repo with no local changes. I can't reproduce the issue and hence cannot help any further. If you are not happy with the library, it is unfortunate. hope you find something that works better for you.

Which folder do you open in Android Studio to see the demo application?

I get this error in the Porcupine class.

I've imported the library successfully:

However I still get this error. None of the native methods seem to work. The .so files are there.

I get the same error in your demo application without changing anything.

[kenarsa]

what do you mean by none of the native methods work? I don't know what is the issue here. I know that other developers have successfully loaded and used the demo app. from the information you provide I can't figure out the issue here. could be something related to your android studio ...

In the porcupine class, I get "cannot resolve corresponding JNI function" on methods like

public native long init();

and etc.

[kenarsa]

can you run any NDK project other than this? I suspect something is wrong with your IDE/toolchain setup ...

Hi man. Sorry, it turns out the NDK is importing properly and that error isn't real.
I decided to debug, and I found this error:

[ERROR] loading parameter file failed with 'IO_ERROR'

I have verified that params.pv exists. The path is /data/user/0/com.package.name/files/params.pv

I think I should open another issue for this, since it's a completely different problem then what we started with.

Facing same error, aar link @kenarsa

Hello, I have error "java.lang.IllegalArgumentException: Initialization of Porcupine failed". I'm sure about address of files "*.ppn and *.pv" and I can open them. but I have this error on this line "object = init(modelFilePath, new String[]{keywordFilePath}, new float[]{sensitivity});"
I'm developing on android studio in windows 10.
