ClassCastException: com.google.zxing.client.android.ViewFinderView

[NBAMj]

I'm getting the following exception:
java.lang.ClassCastException: com.google.zxing.client.android.ViewfinderView cannot be cast to edu.sfsu.cs.orange.ocr.ViewfinderView
at super.onCreate(icicle); in OcrActivity

Android Version: 7.1.1

I think this issue is related to phonegap-plugin-barcodescanner
After removing the barcodescanner plugin the error did not show up.

However, another error is coming now on Android 7.1.1:

09-12 13:33:41.940 19511 19649 V LiveOcrPlugin: Successfully started scanner!
09-12 13:33:41.941 19511 19649 W PluginManager: THREAD WARNING: exec() call to LiveOcrPlugin.recognizeText blocked the main thread for 49ms. Plugin should use CordovaInterface.getThreadPool().

I'm getting this issue on a real device, OnePlus3 Android 7.1.1
On an emulator with Android 7.0, there is no issue and the OcrActivity is running fine and showing camera screen.

I will do further testing and see what's going wrong.

Hi, thanks for opening an issue!
Yes thats for sure because of a conflict with phonegap-plugin-barcodescanner because both of the plugins are based on googles zxing library.

You can ignore the THREAD WARNING, it is just a warning that some of the work should be done on a separate thread, you will see this warning in many plugins.

Thanks for prompt reply.
I tested it on an emulator running Android 7.1.1 and it works perfectly, but I still can't get it run on my OnePlus3.

I'm now getting this log in logcat, it might give you a hint on what the problem is:

Also, is there a way to get both plugins to work togther, your plugin + phonegap-plugin-barcodescanner ?
