and I am getting an error as below :

Error

/home/abc/Android/Sdk/tools/lib is not supported.Use -classpath instead.

Error: Could not create the Java Virtual Machine.

Answer

Finally I was able to find out a solution , so just posting the same for other’s reference :

Downgrading the Java version from 9 to 8 resolved the issue :

Command Used :

sudo update-alternatives --config java

This is list out the version installed like this with * on the selected version :

     Selection    Path                                            Priority   Status
------------------------------------------------------------
  0            /usr/lib/jvm/java-9-openjdk-amd64/bin/java       1091      auto mode
* 1            /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java   1081      manual mode
  2            /usr/lib/jvm/java-9-openjdk-amd64/bin/java       1091      manual mode

Press <enter> to keep the current choice[*], or type selection number:

Enter here the number 1 as we need version 8 .

Thats’s all done , rerun uiautomatorviewer .

EDIT:

If You see something like “you don’t have any alternatives” try donwloading openjdk-8 from the link below (for linux)

Install open jdk-8
