Fail to open input file common.res

[eagerowl]

Hi,

I've successfully compiled snowboy for Android using the npm snowboy-detect source and I've created a custom pmdl file to use with it.

I'm trying to get the port to work with my custom pmdl (or even just the snowbody.umdl, neither work) but I'm receiving the following issue when instantiating the Snowboy-detect constructor with a resource file and model:

snowboyDetector = new SnowboyDetect("/sdcard/snowboy/common.res",
                "/sdcard/snowboy/snowboy.umdl");
snowboyDetector.SetSensitivity("0.45");         // Sensitivity for each hotword
snowboyDetector.SetAudioGain(2.0f);              // Audio gain for detection

But I receive the following error:

A/libc: /Volumes/Android/buildbot/out_dirs/aosp-ndk-r11-release/build/tmp/build-72234/build-libc++/ndk/sources/cxx-stl/llvm-libc++/../llvm-libc++abi/libcxxabi/src/abort_message.cpp:74: void abort_message(const char *, ...): assertion "terminating with uncaught exception of type std::runtime_error: ERROR (snowboy::Input::Input(const string&)():snowboy-io.cc:266) Fail to open input file "/sdcard/snowboy/common.res"

"Fail to open input file "/sdcard/snowboy/common.res""

The path I'm using is /sdcard/snowboy/common.res and the file exists in the location.

Can anyone suggest what's wrong?

Thanks

Were you able to run the Snowboy Android demo? https://github.com/Kitt-AI/snowboy/tree/master/examples/Android/SnowboyAlexaDemo

That should work, and you can start from there.

Thanks for the tip, I hadn't considered that. I fixed the problem by changing two things:

1. using the copyToSdCard method rather than placing the files manually in storage
2. changing the targetSdkVersion to 22 from 26 to suit my device. I believe they handle permissions differently.

Thanks

Thanks for letting us know. Changing the target sdk version might be critical for your device.

I had the same issue with common.res file on Android. For solving this issue just check 2 points:

1. I/O File mechanism. (file AppResCopy.java in demo app)
2. Permissions. If you are using device with Android M or above, you should request runtime permissions for READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE and RECORD_AUDIO.

@Lebedinsky if you have time to submit a PR for it, that would be great!
