If you have opted your app into Google Play managed signing, then you need to use a different set of steps to get the correct signature hash.

User below command in terminal of android studio to generate release key hash

keytool -exportcert -alias [aliasname] -keystore [your app keystore path] | openssl sha1 -binary | openssl base64

And below code in your project to get development key hash

try {
    android.content.pm.PackageInfo info = getPackageManager().getPackageInfo(
            "com.apps.sonictonic",
            android.content.pm.PackageManager.GET_SIGNATURES);
    for (android.content.pm.Signature signature : info.signatures) {
        java.security.MessageDigest md = java.security.MessageDigest.getInstance("SHA");
        md.update(signature.toByteArray());
        android.util.Log.d("KeyHash", "KeyHash:" + android.util.Base64.encodeToString(md.digest(),
                android.util.Base64.DEFAULT));

    }
} catch (android.content.pm.PackageManager.NameNotFoundException e) {

} catch (java.security.NoSuchAlgorithmException e) {

}

Call this method in your Activity onCreate() and Search your key in logcat using key "HashKey"

public static void printHashKey(Context pContext) {
    try {
        PackageInfo info = getPackageManager().getPackageInfo(getPackageName(), PackageManager.GET_SIGNATURES);
        for (Signature signature : info.signatures) {
            MessageDigest md = MessageDigest.getInstance("SHA");
            md.update(signature.toByteArray());
            String hashKey = new String(Base64.encode(md.digest(), 0));
            Log.d("HashKey", "printHashKey() Hash Key: " + hashKey);
        }
    } catch (NoSuchAlgorithmException e) {
        Log.e(TAG, "printHashKey()", e);
    } catch (Exception e) {
        Log.e(TAG, "printHashKey()", e);
    }
}
