There is two field you can enter the key hashes, maybe you entered it in the wrong one. Also to get the key hash you can try this code :

PackageInfo info;
try {
info = getPackageManager().getPackageInfo("com.you.name", PackageManager.GET_SIGNATURES);
for (Signature signature : info.signatures) {
    MessageDigest md;
    md = MessageDigest.getInstance("SHA");
    md.update(signature.toByteArray());
    String something = new String(Base64.encode(md.digest(), 0));
    //String something = new String(Base64.encodeBytes(md.digest()));
    Log.e("hash key", something);
}
} catch (NameNotFoundException e1) {
    Log.e("name not found", e1.toString());
} catch (NoSuchAlgorithmException e) {
    Log.e("no such an algorithm", e.toString());
} catch (Exception e) {
    Log.e("exception", e.toString());
}

Unfortunately.I ran your code .But My app give same error.Other way; I use this command for I create key hashes

keytool -exportcert -alias androiddebugkey -keystore "C:\Users\admin.android\debug.keystore" | "C:\openssl\bin\openssl.exe" sha1 -binary | "C:\openssl\bin\openssl.exe" base64

At the same time really I sure .I have not mistake while I entered key hashes into Development Key Hashes field.do you have got different solution?
