This logic doesn't match the C++ side.

You want to split on ",", iterate and trim each entry and compare. Otherwise,
this would match e.g. "gzip-foo". How about just passing the string value of
this header to the C++ side and having the C++ code use the same logic as it
currently does to parse it.

Done.

             VariationsSeedBridge.setVariationsFirstRunSeed(
-                    getApplicationContext(), rawSeed, signature, country);
+                    getApplicationContext(), rawSeed, signature, country, date, isGzipCompressed);

         } catch (IOException e) {
             Log.w(TAG, "IOException fetching first run seed: ", e);
