I'm building an Android app with image classification using Cordova and the MobileNet model from Tensorflow.js. When I try to run the app in an Android emulator, it crashes.
In the browser everything works fine, the error only happens in the mobile app.
Running adb logcat gives the following error log:

Here is an excerpt from my package.json:
{
...
"dependencies": {
"@tensorflow-models/mobilenet": "^1.0.0",
"@tensorflow/tfjs": "^1.0.4",
...
}
}
And here is the relevant part for the image classification:
import * as mobilenet from '@tensorflow-models/mobilenet';
let image = document.getElementById('my-image');
// The following lines lead to the app crash
mobilenet.load()
.then(model => {
return model.classify(image);
})
.then(predictions => {
console.log(predictions);
});
I expect the image classification to work in the emulator just as it does in the browser.
