sampleapp can not run

[holywend]

I am trying out tor on android, since im new and got not sure where to start, so I go for the sampleapp, but it does not run as I expected

Gradle sync issue

then I solve it with comment out the gradle-wrapper.properties

but then when I sync and run it again now its showing blank webView

and got this on the Run terminal

E/JavaBinder: !!! FAILED BINDER TRANSACTION !!!  (parcel size = 340)
W/GmsClient: IGmsServiceBroker.getService failed
    android.os.DeadObjectException: Transaction failed on small parcel; remote process probably died, but this could also be caused by running out of binder buffe

any idea what might cause this? and how to fix?
