Android Google登录配置失败解决方案

已完成的基础配置

已在Firebase控制台开启Google登录功能
已配置调试、正式环境的SHA1密钥
已将google-services.json文件放置在项目app目录下
登录功能代码如下：

private void loginWithGoogle() {
    GoogleSignInOptions signInOptions =
            new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                    .requestEmail()
                    .build();
    GoogleSignInClient client = GoogleSignIn.getClient(this, signInOptions);
    startActivityForResult(client.getSignInIntent(), Key.GOOGLE_SIGN_IN);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    // Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
    if (requestCode == Key.GOOGLE_SIGN_IN) {
        GoogleSignIn.getSignedInAccountFromIntent(data)
                .addOnSuccessListener(new OnSuccessListener<GoogleSignInAccount>() {
                    @Override
                    public void onSuccess(GoogleSignInAccount googleSignInAccount) {
                        Log.d("werte", "Login successful");
                    }
                })
                .addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception e) {
                        Toast.makeText(MainActivity.this, R.string.loginFailed, Toast.LENGTH_SHORT).show();
                        e.printStackTrace();
                    }
                });
    }
}
