Android studio device monitor doesn't open on mac?

Question

My Android Studio version is 3.0.1 running JRE 1.8.0_152 on a Macbook Pro.

Every attempt at opening device monitor is followed by this error message:

See the log file
/Users/MyName/Library/Android/sdk/tools/lib/monitor-x86_64/configuration/1516320779478.log.

Here is the error log:

I have just recently downloaded Android Studio with recommended settings so I'm not sure why it's not functioning properly. I am using Java 9 for my system but for Android Studio, I am using its embedded JDK. So far, I have tried to:

• Uninstalling and reinstalling Android Studio
• Running device monitor with sudo command
• Setting JDK's path to Java 9 (which seems to be unsupported as Gradle could not sync)
• Redownloading JDK with Homebrew

I could not find many solutions online for the Mac OS and the few I found did not work. Please help!

I realize that Device Monitor is dependent on the java version you have installed on your machine . I downgraded to Java 8 and it worked.
