Start preview failed

[Ray13]

I'm using this library on Tablet Asus, model number "P01T", with android 6.0.1

there is an error when starting the camera:

Both my project and your example generate the same problem... any idea?

Thanks

I'm facing a similar stack trace if there any potential fix to this issue?

[djkskqyr3]

same here

Same here. Occurs on Huawei P8 devices according to Fabric

[djkskqyr3]

I used other library instead of implementation 'com.dlazaro66.qrcodereaderview:qrcodereaderview:2.0.3'

This is library what I used implementation 'me.dm7.barcodescanner:zxing:1.9.8'

[tomerpetel]

Thanks! I'll check it out
