The README doesn't indicate what has to be done in order to get a working demo.

I built and installed the APK, but logcat errors indicated that some files were missing. The directory in question (/storage/emulated/0/snips_android_assistant/) can be created manually in an adb shell session, and most of the files are inside the assistant_proj*.zip file that can be downloaded from your site, and I copied them over. However, even after placing these inside snips_android_assistant, there's a remaining detail-lacking error about missing files in /storage/emulated/0/snips_android_assistant/custom_asr

Thank you for this neat platform and helpful demo.
I am wondering if it is possible to query the platform without using voice?
In otherwords, matching text input to intent.

I am aware of dialogflow and rasa and other similar solutions but I would really like to solve everything offline.

Here is the relevant stacktrace

Hi!
How can we configure the IP address and the port of the MQTT broker?
I would like to have this Android prototype publish actions in a dedicated broker I have subscribed on in another computer.
How can we do that?

I have an application in Google Play (beta release) that seems to be crashing when starting the dialog. I didn't see this error when testing the application locally on different devices.

The same error occurred on multiple devices, running Android 8.0 , Android 9.0, and Android 6.0. The application running Snips v0.58.3. Out of 13 installs, I have a 4 reported devices crashing.

Since the error reported is "caused by: data provided contains a nul byte" with a misspelled "nul" word, I assume this is an internal reported error. The error is also identical across all devices.

java.lang.RuntimeException: Dialogue failed to start

I am not sure how to reproduce the error in development, so any insight as to the issue would be great. My concern is that the Snips APK has stability issues and its not production ready, so I would be able to fully publish an Android application built with the Snips SDK.

The application can be side-loaded using the release section of project page https://github.com/thanksmister/voice-panel-android.
