一段时间后，条码扫描器抛出java.lang.UnsatisfiedLinkError

Question

我有一个条形码扫描器，使用新的android视觉库，在我的设备和其他几个设备上工作得很好。但是它突然停止工作，我在日志中看到以下异常:

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)

测试barcodeDetector.isOperational()返回true。有人知道吗?

这可能有助于针对Google Play Services 8.1重新编译您的应用程序。这个解决方法很快就会出现在https://developers.google.com/vision/release-notes。
