Previously, I took this question to resolve a simple issue on creating Android module due to spaces in the directory. Now, the problem is that after I followed the guides on correct workspace directory guide, the JDT is still not installed currently in this status even after I followed this document in how to install JDT.
I have some questions regarding this topic: Is it necessary needed to have JDT installed to create and export Android module? If yes, what would be the best way to remove this warning so that every time making new Android module on a different workspace directory?
