E/WVMExtractor: Failed to open libwvm.so: dlopen failed: library "libwvm.so" not found

I am currently getting the following error:

E/WVMExtractor: Failed to open libwvm.so: dlopen failed: library "libwvm.so" not found

After enabling setDebugImageMetadataSettings to debug why OCR not reading Card properly on Android,

The full code for MetadataSettings and MetadataSettings.ImageMetadataSettings.DebugImageMetadataSettings is as follows:

MetadataSettings.ImageMetadataSettings.DebugImageMetadataSettings dims = new MetadataSettings.ImageMetadataSettings.DebugImageMetadataSettings();
dims.setAll(true);

MetadataSettings.ImageMetadataSettings ims = new MetadataSettings.ImageMetadataSettings();
ims.setDewarpedImageEnabled(true);
ims.setSuccessfulScanFrameEnabled(false);
ims.setDebugImageMetadataSettings(dims);

I am currently testing under the following environment:

OS name: Android OS version: 7.0 Model: Lenovo P2a42

Hi!

Does your app crash after printing that error or it simply ignores it and continues to work? Our recognition code does not use in any way libwvm.so, however after some research I've found that it is being indirectly used by audio player. Our ScanActivity plays a "beep" sound on successful scanning and on your device the audio subsystem might be broken (googling for this error reveals that lots of apps are suffering from it on some devices).

You can disable the "beep" sound by sending invalid resource ID (such as -1) to ScanActivity or by creating your own scan activity according to documentation and example.

Hi @shekharartemedia, what do you mean by "custom camera"? It seems that this error is not related to our SDK. We still need full stack trace and more information from the log output.

[shekharartemedia]

I have create my custom camera where user can click his/her photos and i am adding the watermarking on the image and save it to the gallery.But when i click on gallery button which is in camera screen then screen is hang.

Hi @shekharartemedia, I don't see in which way this issue is related to our SDK, please ask here only questions that are related to our SDK.
