Answer 2

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.

Answer 3

try this,

goto Android->sdk make sure you have all depenencies required . if not , download them . then goto File-->Settigs-->Build,Execution,Depoyment-->Gradle

choose use default gradle wapper (recommended)

and untick Offline work

gradle build finishes successfully for once you can change the settings

Answer 4

Build -> Clean Project

Another time I had to:

File -> Sync Project with Gradle Files.
