Unsupported method BaseConfig getApplicationIdSuffix

Question

So I m reading Android 6 for Programmers  An App-Driven Approach and the first two app examples I had no issues with the examples  this time the FlagQuiz example when loaded in Android Studio 3 0 Canary-3 I m getting this error which isn t letting me build the project      Error Unsupported method  BaseConfig getApplicationIdSuffix      The version of Gradle you connect to does not support that method    To resolve the problem you can change upgrade the target version of Gradle you connect to    Alternatively  you can ignore this exception and read other information from the model    You can download the source from the book site here to test with the same code base that I m testing from

First  open your application module  build gradle file   Check the classpath according to your project dependency  If not change the version of this classpath   from   classpath  com android tools build gradle 1 0 0    To   classpath  com android tools build gradle 2 3 2    or higher version according to your gradle of android studio   If its still problem  then change buildToolsVersion   From   buildToolsVersion  21 0 0    To   buildToolsVersion  25 0 0    then hit  Try again  and gradle will automatically sync  This will solve it

Alright I figured out how to fix this issue    Open build gradle and change the gradle version to the recommended version  classpath  com android tools build gradle 1 3 0  to classpath  com android tools build gradle 2 3 2  Hit  Try Again  In the messages box it ll say  Fix Gradle Wrapper and re-import project  Click that  since the minimum gradle version is 3 3 A new error will popup and say The SDK Build Tools revision  23 0 1  is too low for project   app   Minimum required is 25 0 0 - Hit Update Build Tools version and sync project A window may popup that says Android Gradle Plugin Update recommended  just update from there    Now the project should be runnable now on any of your android virtual devices
