Unable to launch uiautomatorviewer in mac os high sierra

Question

Need help!

I have the problem, I can't run uiautomatorviewer on mac os high sierra

My path:

export ANDROID_HOME=/Users/XXX/Library/Android/sdk
export JAVA_HOME=$(/usr/libexec/java_home)
export PATH=${JAVA_HOME}/bin:$PATH
export PATH=${PATH}:${ANDROID_HOME}/tools/bin
export PATH=${PATH}:${ANDROID_HOME}/platforms-tools
export PATH=${PATH}:${ANDROID_HOME}/build-tools/27.0.1
export PATH=${PATH}:${JAVA_HOME}

---

Get Error:

Djava.ext.dirs=/Users/mu/Library/Android/sdk/tools/lib/x86_64:/Users/mu/Library/Android/sdk/tools/lib is not supported.  Use -classpath instead.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Thank you.

Hi, thank you for your help, When i used sdkmanager – -list, I Get this:

Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema at com.android.repository.api.SchemaModule$SchemaModuleVersion.<init>
(SchemaModule.java:156) at com.android.repository.api.SchemaModule.<init>
(SchemaModule.java:75) at com.android.sdklib.repository.AndroidSdkHandler.
<clinit>(AndroidSdkHandler.java:81) ................................... –

And then I try to start uiautomatorviewer and I have this:

-

Djava.ext.dirs=/Users/mu/Library/Android/sdk/tools/lib/x86_64:/Users/mu/Lib
rary/Android/sdk/tools/lib is not supported.  Use -classpath instead.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Make sure the java path set correctly. To verify the java Environment Variables have been set correctly use this cmd: java -version

If the path is correct, still getting the same error then try to increase vm heap option. If you are using Terminal, run command

open -e /Applications/Android\ Studio.app/Contents/bin/studio.vmoptions

edit your studio.vmoptions file

-Xms1024m
-Xmx1024m
-XX:MaxPermSize=1024m
-XX:ReservedCodeCacheSize=200m
-XX:+UseCompressedOops

and restarted Android Studio. Should work fine

If not also verify that Android Environment Variables have been set correctly. Use this command: sdkmanager – -list

By the way please find the below steps to set Android Studio:

Step 1: Download and Install latest version of Java 8 (JDK)

Step 2: Setup Java Environment Variables.

Step 3: Download and Install Android Studio.

Step 4: Install additional Android SDK tools(If not present).

Step 5: Setup Android Environment Variables :

ANDROID_HOME - (/YOUR_PATH_TO/android-sdk) Ex : export ANDROID_HOME=/Users/username/Library/Android/sdk

In Android SDK folder, there are three specific folders that you need to add to the Path variable

platforms-tools : folder (path – /YOUR_PATH_TO/android-sdk/platform-tools)

tools :folder (path – /YOUR_PATH_TO/android-sdk/tools)

bin : folder inside tools (path– /YOUR_PATH_TO/android-sdk/tools/bin)

Hope this helped.
