Its because the generate hash key is wrong.
To solve follow this steps:
Paste the following code in oncreate().
try {
PackageInfo info = getPackageManager().getPackageInfo(
"com.example.packagename",
PackageManager.GET_SIGNATURES);
for (Signature signature : info.signatures) {
MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
}
} catch (NameNotFoundException e) {
} catch (NoSuchAlgorithmException e) {
}
