IssueTracker

Hello!

It is at least the third time I'm affected by this bug, and this time, it took me months to finally resolve it again… until next time.

The symptoms

The IDE believes that the JDK classes are not in the classpath, leading to unresolved references for types like java.util.Locale, or errors like the following:

Cannot access 'java.io.Serializable' which is a supertype of 'kotlin.Long'. Check your module classpath for missing or conflicting dependencies

The (IMO ugly) workaround

Removing the options/jdk.table.xml file, located in ~/Library/Application Support/Google/AndroidStudioPreview20XX.X/options/jdk.table.xml on macOS, while Android Studio is not open fixes the issue, which no longer appears after opening Android Studio back after that.

The reasons why I believe this workaround is ugly are the following:

• It's never suggested by the IDE as a quick-fix.
• It's not fixable through IDE settings.
• I had to reach out to a Googler personally through a private channel to figure this out.
• There's no public knowledge of that one can find by searching on Google (oh and this issue tracker is still not indexed on Google, so this report is not changing that alone…).
• It's not a permanent fix and happens again after who knows what.
• Android Studio insists on downloading new Android SDK related stuff, worth around 300MB when I already had a perfectly working SDK installation, which can be a big problem for the many developers that don't have the 800+ Mbps internet I'm so lucky to have (1Mbps internet is still very common for many homes in Africa and Europe, 300MB download is a 40 minutes penalty if you have the entire bandwidth for you, enough connection stability, and the patience).

Some clues to help you in fixing that

I attached the old jdk.table.xml file I had (with the .old extension), and the new one that Android Studio generated itself so you can compare them and try to trace how the mess-up happened.

I'd be curious to know what happens again, and I hope we can find a reliable fix for that issue sooner than latter to help Android developers, especially the beginners.
