Bug: doesn't work on stock (vanilla) Nexus 5

[AndroidDeveloperLB]

Android 6.0.1, MOB30H

running the sample "photo-demo" , it just shows this in the logs:

05-18 12:24:56.710 3280-3280/com.google.android.gms.samples.vision.face.photo W/FaceDetectorHandle: Native face detector not yet available.  Reverting to no-op detection.
05-18 12:24:57.028 3280-3280/com.google.android.gms.samples.vision.face.photo W/PhotoViewerActivity: Face detector dependencies are not yet available.

I tried updating everything, and change the gradle file to this:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "com.google.android.gms.samples.vision.face.photo"
        minSdkVersion 14
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.4.0'
    compile 'com.google.android.gms:play-services:8.4.0'
}

But it didn't help. Running the exact same project on Nexus 5x with Android 6.0.1 actually does work.

How could this be?

There is a known issue with the new version of GMSCore (v9) that was just released today. From the release notes:

• A service required by Mobile Vision is now disabled due to a serious bug in that service. This will prevent users who have not already used face or barcode detection from using those features. We do not recommend adding new Mobile Vision features to your app until this issue is fixed.
• For apps that already use Mobile Vision features, check FaceDetector.isOperational() or BarcodeDetector.isOperational() to confirm detector readiness before using the face or barcode detector.

Even though I don't use it still, what would have happened if I made an app, say, 2 months ago, that uses this ? Wouldn't this mean that now it won't be able to use this API, and fail for all users with this bug? How could it be that you update the version , before checking it on Nexus devices...

@mbg1 Do you have at least any time frame for fixing this issue? I mean, Are we speaking about days, weeks, months? I have started a project a few weeks ago with your API and it scares me a bit, especially as GMS did not receive any update in last months (I mean I hope we will not wait as long for a fix to this...)

We are working to correct the problem as soon as possible. We expect it will take several weeks to test it thoroughly.

@AndroidDeveloperLB Looks like you have the same porblem I had a few months ago on Nexus 5x See https://github.com/googlesamples/android-vision/issues/63

@mbg1 Can you update its current status? Yesterday, on factory resetting the device, the application downloaded the mobile vision api and started working. I was using Moto G (XT1031) running android 4.4.4 updated to Google Play Services 9.0.82. Also this downloaded on emulators as well.

However on Moto X (XT1060) running android 5.1 is not downloading no matter what the version of play services is. Tried on the following versions:

• 9.0.83
• 9.0.82
• 8.4.89
• 7.8.99

Can you please explain why is this working on moto g and emulators ?

I believe this is fixed with latest release. Correct me if I am wrong. Google Play services 9.2

• Resolved issues with a service required by Mobile Vision barcode detection and face detection. All users can once again use barcode and face detection functionality. For more information, see Mobile Vision Release Notes.
• Added Text API: optical character recognition for Latin character text (English, Spanish, German, French, etc.) in photos. Text API returns the organizational structure of the text (paragraphs, lines, words) as well as the text itself.
