在真实设备中进行测试时，snackbar在失败和成功案例中都可以正常工作。但是在playstore中，它显示了小吃店中的崩溃。我找不到问题出在哪里。以下是在Playstore中显示的错误。

java.lang.IllegalArgumentException:

下面是快餐栏的代码段

snackbar snackbar1 = snackbar
        .make(login_root,R.string.server_error,snackbar.LENGTH_LONG)
        .setaction(R.string.retry,new View.OnClicklistener() {
            @Override
            public void onClick(View view) {

                Fragment login = new LoginFragment();
                FragmentTransaction ft = getFragmentManager().beginTransaction();
                ft.replace(R.id.fragment_frame,login);
                ft.commit();
            }
        });
snackbar1.setactionTextColor(Color.RED);
View sbView1 = snackbar1.getView();
TextView textView1= (TextView) sbView1.findViewById(com.google.android.material.R.id.snackbar_text);
textView1.setTextColor(Color.WHITE);
snackbar1.show();
