问题
I have a barcode scanner using the new android vision library that worked perfectly on my device and on several others. But suddenly it stops working and I see the following exception in the log:
No implementation found for com.google.android.gms.vision.barcode.internal.NativeBarcode[] com.google.android.gms.vision.barcode.internal.NativeBarcodeDetector.recognizeBufferNative(int, int, java.nio.ByteBuffer, com.google.android.gms.vision.barcode.internal.NativeOptions) (tried Java_com_google_android_gms_vision_barcode_internal_NativeBarcodeDetector_recognizeBufferNative and Java_com_google_android_gms_vision_barcode_internal_NativeBarcodeDetector_recognizeBufferNative__IILjava_nio_ByteBuffer_2Lcom_google_android_gms_vision_barcode_internal_NativeOptions_2)
E/CameraSource: Exception thrown from receiver.

The test barcodeDetector.isOperational() returns true.
Has anyone an idea?

It may help to recompile your application against Google Play Services 8.1. This workaround will appear shortly at https://developers.google.com/vision/release-notes.
