Does not read the QR on Huawei devices

[danielemaddaluno]

The activity works fine, I even see the camera working good but there is no text scan.
My phone is a Huawei P10 Lite (WAS-LX1AC432B198)

Same problem occurred on Huawei MediaPad T3 10(AGS-W09C229B251).
Until May 10th, the device could read the QR.
But since May 11th, the device hasn't read.

Same problem here.
Lots of users had reported this problems occurred on Huawei over the past few days.

Yes,

Same problem here, with the test app and our app which is in production (available in Google Store). HUAWEI FRD-L09 (Android 7.0, API 24) (Honor 8)

I manage to let it work by...

inform my user (internal user) to download application with WiFi only!
Becuase, there is some setting in Huawei can limit background service on other connectivity except WiFi.

But this is just a workaround, plz help us fix this issues.

[sattha]

Yeah for some device (but still Huawei) what I have done to fix this issue so far from my above comment is

1. ask them to check gms service, is there any update https://play.google.com/store/apps/details?id=com.google.android.gms
2. if already update, I ask them to clear google play service cache
3. open an app and wait for some time (5 min.), I have experienced that at first, it does not operate but wait for a while it does (it's due to a network).

additional but not necessary for above workaround
I also, update my AndroidManifest.xml by adding the following one

<meta-data 
            android:name="com.google.android.gms.vision.DEPENDENCIES" 
            android:value="barcode" />

The problem of this issue is gotten on all the Huawei with an equal or higher os than 7. Google Play Services has been uploaded to 12.6.85 to solve the problem on Maps (apps like Uber were getting an error) but it seems that the error persist on the MobileVision library. Do anybody knows an email to report the google team?

I'm seeing the same issue, but apparently only on devices with the hardware support level of "Limited" (which unfortunately means a lot of Huawei devices). Not seeing the same issue on an older P8 lite ("Legacy").

Meanwhile all devices updated to the fixing version 12.6.85, however one still needs to clear the app data of the Play Services manually in order for the vision lib to work again.

Same problem on Huawei P10 Lite

[ngallazzi]

Same problem on Huawei P9 Lite and on Huawei P20

@ngallazzi @andreasciarra try to clear the app data of the Play Services (cache is not sufficient) and you should be back to normal.

I solved it adding in the manifest what @sattha said
<meta-data android:name="com.google.android.gms.vision.DEPENDENCIES" android:value="barcode" />
And deleting all data and cache of Google Play Services and Google Play services for Instant Apps.

Hi @bertam, could you do this test? Reboot your Huawei and then, try to scan the barcode again. In my case the error is there again...

[elekiwi]

You are right @kiketen , I have to delete all the data and cache again in order to make it work.
