2. npm i & npm run build
3. Download the models

Visit http://:8080/examples/object_detection/index.html on the mobile and switch to SSDLite MobileNetV2(TFlite)

Info:

Google Pixel 2(Android 8.1.0)--> crash
HUAWEI P20 Pro(Android 8.1.0)--> crash
Google Pixel 2(Android 9)--> works
Google Pixel 2 XL(Android 9)--> works

Seem it's an Android 8.1.0 special issue.

This doesn't seem to be a problem of demo code or our chromium implementation. From the log, the process blocked in this call ANeuralNetworksEvent_wait.

Thanks for the report and investigation @Christywl @pinzhenx ! If it is only Android 8.1.0 issue, let's record it and lower it priority.

@Christywl please retest this bug on latest build.

huningxin commented 5 years ago

This might be fixed by https://github.com/intel/webml-polyfill/issues/517. Please help double check.

Android 8.1.0 (HUAWEI P20 Pro): On the latest build https://github.com/otcshare/chromium-src/commit/20fce9c04a478d8e81e868223bb02e1cd79f0a45, the browser didn't crash, but SSDLite MobileNetV2(TFlite) still doesn't work on NNAPI, the box is stuck on "Setting...".

ibelem commented 5 years ago

@Christywl please retest it on both Android 9 and 8.1, if repros on 8.1 only, lower the priority and remove the target milestone. or won't fix.

Retested on Android 9 and Android 8.1.0:

HUAWEI P20 Pro(Android 8.1.0)--> stuck on "Loading model ..."
Google Pixel 3(Android 9)--> works
Google Pixel 2 XL(Android 9)--> works

It's only Android 8.1.0 issue, so I removed the target milestone.
