Multiple hotwords for Android

[TyMarc]

Looking at the documentation, we have an example to use multiple models for detection in python. I'm currently working on an Android application that uses your library and it's working great with one model. If I initialise the SnowboyDetect with two models using "file/path/1.pmdl,file/path/2.pmdl", it crashes directly.

http://docs.kitt.ai/snowboy/#multiple-models-and-callbacks

Is it not supported on Android even if it's only a wrapper?

[TyMarc]

I've looked into the .cc files of the Python and Android implementations and they look exactly the same as per what they are doing before sending the model string to the .so file.

For reference, my model string look like this:

modelStr=/data/user/0/com.example.test/files/recognition/start_recording.pmdl,/data/user/0/com.example.test/files/recognition/hold_the_call.pmdl

As soon as I pass this model string in the JNI, I have a fatal crash:

Any help available?

You have to change the sensitivity. If you have two models, provide the sensitivity as something like "0.5,0.6", where the sensitivity of the first model is 0.5, and that of the second is 0.6

[TyMarc]

Thanks a bunch, it's working!

[naveensingh]

"0.6,0.5" doesn't seem to work in SnowboyAlexaDemo app for two models,
At first, I used

detector.SetSensitivity("0.6,0.5")

in RecordingThread.java.

It crashed, so I used this in SnowboyDetect.java wrapper :

snowboyJNI.SnowboyDetect_SetSensitivity(swigCPtr, this, "0.8, 0.5");

this too crashed. :(

(I'm new to java, so forgive me for stupidity ;)
Please help
