One day, I want to increase my Android Studio performance, I add some parameters in studio64.exe.vmoptions
-Xms2048m
-Xmx4096m
-XX:MaxPermSize=512m
-XX:ReservedCodeCacheSize=768m
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=50
-XX:+UseParallelGC
Then, I can not open Android Studio again!
So! what magic parameter make it wrong?
I google the message for that but all about JAVA_HOME environment issue.
Finally, I found that is ONE bad parameter on that:
-XX:+UseParallelGC
Remove it and restart Android Studio, it work again!
