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

Question

I'm trying to install the latest Android Studio on a MacBook pro 2015

Unfortunately I get this error:

An error occurred while trying to compute required packages.

Here a screenshot of the error:

which is not very informative. What's causing the problem?

EDIT

This is the exception I get when I run the application from the terminal:

EDIT

Google has fixed the bug. Just download the new installer and everything should be fine

Answer 1

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 bin folder to the PATH.
2. Install the latest platform: in a terminal, execute sdkmanager "platforms;android-25"
3. Open Android Studio, and go 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.

Answer 2

Updated: It should be fixed now.
