I am unable to run Android Monitor. I am using Android Studio. Not Eclipse.

WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by org.eclipse.osgi.internal.baseadaptor.BaseStorage (file:/Users/kidus11/Library/Android/sdk/tools/lib/monitor-x86_64/plugins/org.eclipse.osgi_3.8.2.v20130124-134944.jar) to method java.net.URLClassLoader.addURL(java.net.URL) WARNING: Please consider reporting this to the maintainers of org.eclipse.osgi.internal.baseadaptor.BaseStorage WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations WARNING: All illegal access operations will be denied in a future release

Here is the tag I see every time I try to open Android Device Monitor

!ENTRY org.eclipse.osgi 4 0 2017-10-04 20:18:12.531 !MESSAGE Application error !STACK 1 java.lang.IllegalStateException: Unable to acquire application service.

  • reason: monitor not support java 8+
  • solution: change Java (your java 9) to Java 8

Append

how set Java 8 in macOS

  • find java home path
 /usr/libexec/java_home -V
Matching Java Virtual Machines (4):
    11.0.2 (x86_64) "Oracle Corporation" - "OpenJDK 11.0.2" /Library/Java/JavaVirtualMachines/openjdk-11.0.2.jdk/Contents/Home
    1.8.333.02 (x86_64) "Oracle Corporation" - "Java" /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
    1.8.0_112 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_112.jdk/Contents/Home
    1.7.0_79 (x86_64) "Oracle Corporation" - "Java SE 7" /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home
/Library/Java/JavaVirtualMachines/openjdk-11.0.2.jdk/Contents/Home
  • added into boot script
 cat ~/.bashrc | grep JAVA
#export JAVA_HOME=$(/usr/libexec/java_home)
#export JAVA_HOME=/Library/Java/JavaVirtualMachines/openjdk-11.0.2.jdk/Contents/Home
#export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_112.jdk/Contents/Home
export PATH=$JAVA_HOME/bin:$PATH

You modify Info.plist file in monitor binary directory.

Path example in Mac: 
/Users/{username}/Library/Android/sdk/tools/lib/monitor.app/Contents/Info.plist

Add -vm key of bundled java path into <key>Eclipse</key><array>.(There is a comment.You read it.)

-vm key example

<string>-vm</string><string>/Applications/Android\ 
Studio.app/Contents/jre/jdk/Contents/Home/bin/java</string>

Yes, The Newest Android Studio Bundle comes with its own JRE (under C:\Program Files\Android\Android Studio\jre).

So, You can just copy this jre folder and paste it to here: C:\Users\<Username>\AppData\Local\Android\Sdk\tools\lib\monitor-x86_64

And now in android studio go to the Tools -> Android -> Android Device Monitor.

Or you can prefer this link Resolve Android Device Monitor issue

Not sure what is your use case for Android Device Monitor, but apparently since Android Studio 3.0. most components of the Android Device Monitor are deprecated:

https://developer.android.com/studio/profile/monitor.html

There are other tools that can be used such as Android Profiler...

So maybe it is not really necessary to try to fix this issue.

Newest Android Studio Bundle comes with its own JRE (under <ANDROID_STUDIO>/jre and this is the recommended JRE to work with (look at File / Project Structure / SDK Location).

Likewise, a simple option is to create a symbolic link under the monitor tools to keep JRE in line with Android Studio even getting an update.

For MAC or Linux:

#ln -s <ANDROID_STUDIO>/jre <SDK>/tools/lib/monitor-x86_64/jre

32 bits:

#ln -s <ANDROID_STUDIO>/jre <SDK>/tools/lib/monitor-x86/jre

Then the ddms monitor works for both ways: from Studio IDE (Tools / Android / ADM) or command line (<SDK>tools/./monitor)

Android Studio does not support Java 9 yet. Install JDK 8 and update your studio configurations to point the jre for 8.

Then ensure that you are not setting your JAVA_HOME to 9 yet either. Lastly, make sure you eclipse is not running somewhere on your machine taking ownership of the ADB already.
