Android version has disappeared from Google Play #1700
If you speak Russian, 4pda has a custom 'improved version' that is probably what you need. I can't link to it here, but some searching should help. At least until it is open sourced / brought back to an app store.
Here’s the answer I got from the Developer regarding the license:
============
GoldenDict Mobile is no longer being commercialized, and is probably going to be released as open source in the future.
Meanwhile you can continue using the latest released version, or any previously released one:
You can download the latest version from http://goldendict.mobi/downloads/android/paid/
Older versions are available at http://goldendict.mobi/downloads/android/paid/old/
To get a license file, please use the form at http://goldendict.mobi/free.php. Put a 10-digit device ID into it, and it will let you download the file named 'goldendict-key.txt'. Place it into /sdcard/GoldenDict or /sdcard/GoldenDict/.config dir. You can also simply try opening the downloaded file and choosing 'Install GoldenDict License' to install it automatically.
============
I confirm that it works. What is more, anyone can now use the full version, even those of you who did not buy it while it was on Google Play. And it looks like the Developer has very recently updated the homepage of goldendict.mobi to reflect all of the above information.
