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)

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.
