Question

i try to add recyclerview to my project and get this error appear and i added it from android studio dependencies

User · Answer

in may case I found OneSignal changed their dependencies

so I changed it from

compile 'com.onesignal:OneSignal:[3.5.8, 3.99.99]'

to

compile 'com.onesignal:OneSignal:[3.5.8, 3.5.8]'

then it works, please check any unspecific dependency.

When you sync this dependency to the android studio    implementation  com android support cardview-v7 26 0 1-alpha1    Then  Sync the Gradle with Project Files  It will say   Suppose if you are working on new ones like androidx  obviously  it will show error on the dependency    For that you can go to the File menu and click on the invalidate restart  the code  It will resolve itself and the application will restart without any error
