Android studio error: An error occurred while trying to compute required packages

Update:

There's a manual workaround!

As per post https://stackoverflow.com/a/42733510/7694425 :

1. Download the command line tools, place them in the SDK folder (e.g.,on mac: /Users/user/Library/Android/sdk), and then add the binfolder to the PATH.
2. Install the latest platform: in a terminal,execute sdkmanager "platforms;android-25"
3. Open Android Studio, andgo to the SDK Manager (Appearance and Behavior > System Settings >Android SDK)
4. Click on "Edit", and then select the sdk folder. Then"Next" > "Next" > "Finish".

Still, it doesn't resolve the missing emulator package therefore the Android SDK tools can't be updated since it's a dependency. But Android studio works and you can download other packages.

Looking forward to a better solution.

Update 2:

Solution to emulator package issue!

After digging in the repo's XML for a while I've spotted the issue.

It turns out that the "emulator" package is only in channel 3 (canary) while the "tools" package is in channel 0 (stable) but depends on "emulator". The solution is to force the manager to download the "emulator" package from channel 3:

./sdkmanager --channel=3 emulator

Problem solved!

Previous answer:

The same problem here.

Twitted @androidstudio too. Hopefully someone in a position to fix this will notice.

Updated: It should be fixed now.

This is https://code.google.com/p/android/issues/detail?id=244956 -- we're working on a hotfix.

After lot of struggling I made it work.Here my solution

When I get the "An error occurred while trying to compute required packages" error I just clicked "finished" and then I went to the main Android Studio page:

Then I selected Configure -> SDK manager and I launched the SDK installation from there

Reopened Android Studio and everything was ok

Really, really embarrassing for a software which used to be very good. You can feel the "bloatness" of Eclipse creeping in
