When I execute monkeyrunner I get this:
supers-MacBook-Pro:android-testing manuel$ monkeyrunner
-Djava.ext.dirs=/Users/super/Library/Android/sdk/tools/lib:/Users/super/Library/Android/sdk/tools/lib/x86_64 is not supported. Use -classpath instead.
Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit.
I searched info but I haven't found it. I would appreciate your help.
Well, I solved the problem, I changed java 10 to java 8 in bash_profile, I was working with an unsupported version.
Although I got MonkeyRunner to run, I had the same issue after a while. I solved definitely it changing the extension of Info.plist located in /Library/Java/JavaVirtualMachines/jdk-10.0.1.jdk/Contents to Info.plist.disabled, so macOS system discards this jdk version, and chooses the next higher version, in my case, jdk 1.8.0_45. For more info, you can look here.
