由于Java版本过高，启动uiautomatorviewer失败。
这个错误说明在运行 uiautomatorviewer 时，使用了旧版 Java 启动参数 -Djava.ext.dirs，但这已经在新版 JDK（Java 9 及以上）中被废弃了，导致启动失败。
user@user:/D/Android/Sdk/tools/bin$ ./uiautomatorviewer
-Djava.ext.dirs=/D/Android/Sdk/tools/lib/x86_64:/D/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.
解决办法，运行之前修改java版本为java8。
这里临时设置下。
user@user:/D/Android/Sdk/tools/bin$ java --version
openjdk 11.0.24 2024-07-16
OpenJDK Runtime Environment (build 11.0.24+8-post-Ubuntu-1ubuntu320.04)
OpenJDK 64-Bit Server VM (build 11.0.24+8-post-Ubuntu-1ubuntu320.04, mixed mode, sharing)
user@user:/D/Android/Sdk/tools/bin$ export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
user@user:/D/Android/Sdk/tools/bin$ export PATH=$JAVA_HOME/bin:$PATH
user@user:/D/Android/Sdk/tools/bin$ java -version
openjdk version "1.8.0_422"
OpenJDK Runtime Environment (build 1.8.0_422-8u422-b05-1~20.04-b05)
OpenJDK 64-Bit Server VM (build 25.422-b05, mixed mode)
然后就可以启动了
user@user:/D/Android/Sdk/tools/bin$ ./uiautomatorviewer

使用可以简单参考这个：
Android Studio 中使用uiautomatorviewer插件
类似的还有monitor,版本过高也会启动失败。可以直接加到程序里面（可以直接用vscode等打开修改）。
/D/Android/Sdk/tools/monitor
+export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
+export PATH=$JAVA_HOME/bin:$PATH
exec $app
或者做个启动脚本
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export PATH=$JAVA_HOME/bin:$PATH
cd xxx
./xx
