Android Studio hangs at fetching documentation

Question

Recently I experienced that Android Studio is hanging a lot. Right in the middle of typing in any editor it will hang and block me from doing anything else for a couple of seconds. Restarting or killing adb wouldn't help.

After a while I realized that this happens if the documentation is being loaded and displayed. This happens mostly for Android documentation, which is quite verbose and also seems to contain images and formatting.

I already tried switching off the Auto-update from source option, but that doesn't change anything.

Any ideas what could cause Android Studio to block while it's loading or displaying (or doing whatever with) the documentation?

I'm using Android Studio 2.1.1, the latest build with the security fix.

you can check this solution: https://mcmap.net/q/203033/-android-studio-quick-documentation-always-quot-fetching-documentation-quot

Here's what fixed it for me:

• Make sure you have the Documentation package downloaded in SDK Manager.
• Exit Studio if it's running.
• Delete the file named "jdk.table.xml" located in ~/.AndroidStudioX.Y/config/options/ (remember to take a backup first!).
• Relaunch Android Studio. should work correctly now and it should regenerate the file automatically.

Note:

• This worked for me on Ubuntu 14.04 & Android Studio 0.8.11 (EDIT: Several users are reporting this solution also works for newer versions of Android Studio).
• If it still doesn't work, try deleting and re-downloading the Documentation package from inside Android SDK Manager then try the above steps.
• If you're running Windows, the file is located at "%UserProfile%.AndroidStudio\config\options", and if you're running OS X, it's located at "~/Library/Preferences/AndroidStudio/options" (credits to @Gero and @Alex Lipov).

Fix still works for AS 2.2.3 and MacOS 10.12.2 Sierra
