The cause of the problem is that the class ScannerViewActivity is called inside one of your AAR as a dependency like:

apply plugin: 'com.android.library'
android{...}
dependencies {
    compile 'com.me.scanner:otherscanner@aar' //library which contains ScannerViewActivity
}

but when you use a aar (transitive won't add this aar dependencies !), you have to add the other dependency such as:

dependencies {
...
compile ('com.me.app:scanner@aar')// remove{ transitive = true; }
compile ('com.me.scanner:otherscanner@aar')
...
}
