When you try to build xamarine android projects with Azure Pipelines hosted agent Windows 2019 with VS2019 you might encounter error “XA5300: The Java SDK Directory could not be found”, if you are using a visual studio build task or msbuild task to build a solution which includes android projects. This is caused due to the inability to find the java sdk in the hosted agent. Let’s see how we can get this issue fixed.
