Android Question Porcupine hotword creation

Porcupine is a hotword recognition tool, like "Ok Google" and "Alexa". The library created by donmanfred works very well with predefined hotwords.

But when I tried creating my own hotword the library fails to initialize.
I am using Windows, and this is the command-
B4X:
E:\porcupine\pv_porcupine_optimizer -r E:\porcupine -w "extreme" -p windows -o E:\porcupine

in "E:\porcupine" directory, I have the following files-
porcupine.data
params.pv
pv_porcupine_optimizer.exe

I placed the generated "extreme_windows.ppn" file under "File.DirRootExternal&"/porcupine" folder. When run, the following error occurs:

B4X:
Error occurred on line: 48 (Main)

As far i can help (unfortunately the lib still does not work for me).

I found out that the files generated by the Windowstool seems to be not able to create Files for ANDROID!?

Now i found this (Optimizer/readme.md)
This means that a keyword file generated with ```-p linux``` cannot run on Android or Mac. The
optimizer available at this repository can produce keyword files for Linux, Mac, and Windows platforms. Custom keyword files for other
platforms are provided with a purchase of the commercial license. In order to purchase a commercial license contact contact@picovoice.ai.

So, if you need to create keywords for Android you need to buy a License. Don´t know what it costs/how much it is. You need to contact contact@picovoice.ai

Please remove the Library! I did not allowed to publish the library.
Why don't you want to share this Library? I asked in the Forum (not in a private message because you don't like that) about it two days ago but sadly got no reply. Please explain, because I don't understand why people's appetite first gets wet and then everything halts, despite people like me offering a donation if the wrapper works.

I was HELPFUL with this library too! I DID WROTE IT
I don´t care about the 5 minutes you was too lazy to build the example by yourself.
I deciced NOT to react on Posts from you. Private or open.

Thank you. I don't have the skills to develop a B4A project on the basis of just a JAR, XML and some RAW data. If you don't have the time to make a test project I have no other choice than to let it rest (i.e. no donation, sorry).

Please do not ask me about any Library anymore.

Hi Don

it is a shame not to share your work , maybe into a donationware formula .

Or send me Pm with your price .

Think about it , the voice commands are the new future and do it with B4A will be great !!

You are not able to create new commands with this library. At least not for Android. You need a Commercial License for this.
Additionally the lib still does not work for me. Maybe my Device (Android 8). I don´t know.
I would feel bad if i release it.

It worked fine on my Android 8 device o_O
What issue are you facing?

What issue are you facing?
The initialization does work (i guess). in resume i start and when i try to activate the Keyword used (Alexa_Android) the Lib (the Native) just crashes.
I only could find something in the unfiltered log. But nothing which i could understand.

As i am not interested in this Library i just put it by side... No problem for me at all.

I´m glad it works for you...

Rude and respectless as usual. You didn't even read what I wrote: I was not able to build a project on the basis of what you made. I did try for more than an hour!
Not everyone is an "Expert" like you... You wrote: "I don't have the time to finish the project" which is very strange.
You are now on my ignore list. Go fly a kite.
