E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.example.root.filesactivity, PID: 28319
java.lang.IllegalStateException: There must be a com.dropbox.core.android.AuthActivity within your app's package registered for your URI scheme (db-srlvvanpolzcks2). However, it appears that an activity in a different package is registered for that scheme instead. If you have multiple apps that all want to use the same accesstoken pair, designate one of them to do authentication and have the other apps launch it and then retrieve the token pair from it.
