Google Vision FaceTracker shows a black screen

问题:

Can someone try Google VisionAPI FaceTracker and see if it works?

Here's the official page.

All I get when I try running it is a black screen (after fixing one error). I don't get any errors in the logs either.

The sample works for me. Of particular note: you should not need to modify the samples to make them work, they should just work.

As such, I also just ran the Face tracking sample as follows:

• git clone https://github.com/googlesamples/android-vision
• (Install Android Studio)
• Import android-vision/visionSamples/FaceTracker into Android Studio
• Click the Android Studio things that install SDK 24 / build tools 24
• From the android-vision/visionSamples/FaceTracker folder ./gradlew assemble
• Create a Google API virtual android device with Nexus 5X, setting advanced to a camera when you create the device
• Start your device
• adb install -r ./app/build/outputs/apk/app-debug.apk
• Open up app, accept permission, turn your camera sideways

App looks like this:

The following could be helpful in diagnosing your issue:

• Can you share the output from adb logcat?
• What Android version is the device you're testing the sample on?
• How are you resolving when encountering the "check permission" error?
• What SDK / build tools are you building with (the sample is 0.24)?

Googley Eyes was a little trickier from the emulator because it uses the front camera.
