How to decompress gzip android?

Question

Android

Hello.
For the project, I need to unpack the string packed by the php function

<?php
echo base64_encode(aes(gzdeflate("123456")));

I know about transparent decompression of gzip in OkHttp, but unfortunately it doesn't work because the data is encrypted with aes.
in the end, the program works like this:
we request data from the server, remove aes and only then unpack gzip.
it doesn't make sense to pack with gzip aes, the original data weighs ~ 5 mb, if gzip walks through unencrypted data, they weigh 200 kb, if gzip walks through aes, then 3 mb

android code

public static byte[] decompress(byte[] data) throws IOException, DataFormatException {
        Inflater inflater = new Inflater(true);
        inflater.setInput(data);
        ByteArrayOutputStream outputStream = new ByteArrayOutputStream(data.length);
        byte[] buffer = new byte[1024];
        while (!inflater.finished()) {
            int count = inflater.inflate(buffer);
            outputStream.write(buffer, 0, count);
        }
        outputStream.close();
        byte[] output = outputStream.toByteArray();
     //   LOG.debug("Original: " + data.length);
      //  LOG.debug("Compressed: " + output.length);
        return output;
    }
