Question

Error when merging the dex

following are the dependencies.

ext {
    anko_version=\'0.10.5\'
    support_lib=\'1.0.0-alpha1\'
    room_lib = \"1.1.0\         


        

Answer 1

Check the package which clashes with the com.android.support and exclude it from that package. For me, I was using androidx packages and also FCM, where there was a clash. So, this fixed for me:

implementation ('com.google.firebase:firebase-core:16.0.4') {
    exclude group: 'com.android.support'
}
