Just copy pasted the code after adding dependencies and permissison about code-scanner HOT 9 CLOSED

Let me see the complete list of your dependecies.
And when this error occurs?

from code-scanner.

implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
implementation 'com.google.firebase:firebase-auth:15.0.0'

implementation 'com.journeyapps:zxing-android-embedded:3.6.0@aar'
implementation 'com.budiyev.android:code-scanner:1.8.8'

from code-scanner.

Probably, you shoud remove these two:
implementation 'com.google.zxing:core:3.2.1'
implementation 'com.journeyapps:zxing-android-embedded:3.6.0@aar'

from code-scanner.

from code-scanner.

implementation 'com.google.zxing:core:3.2.1'
implementation 'com.journeyapps:zxing-android-embedded:3.6.0@aar'

Try to remove these two, then clean project and rebuild. Code Scanner uses the latest version of ZXing:
'com.google.zxing:core:3.3.2'
'com.google.zxing:android-core:3.3.0'

These conflicts are, probably, the reason of build failures.

If clean -> rebuild doesn't help, try clean -> invalidate caches / restart -> rebuild

And the last try can be: commit with new dependencies, remove all files from your project directory (except .git), then type in console git reset --hard, open Android Studio, remove your project from list, and open it again by "open an existing android studio project" button.

from code-scanner.

Class com.google.zxing.client.android.camera.CameraConfigurationUtils is present in 'com.google.zxing:android-core:3.3.0' dependency of Code Scanner.

from code-scanner.

Im using com.journeyapps.barcodescanner.BarcodeEncoder , but when I remove implementation 'com.journeyapps:zxing-android-embedded:3.6.0@aar' and use yours, I cant access the BarcodeEncoder? Any tips about this?

from code-scanner.

from code-scanner.

CamearaConfigurationUtils copy-pasted in zxing-android-embedded library (not added as transitive dependency), this causes build failures. I recommend to create issue in zxing-android-embedded repository and ask developer to chenge this (and link this issue).

For now, we can exclude the dependency with conflicting class from code-scanner:

implementation ('com.budiyev.android:code-scanner:1.8.9') {
exclude group: 'com.google.zxing', module: 'android-core'
}

But I can't guarantee stable work, because of probable changes in copy-pasted class and different version of android-core from which this class was copied.
