我正在使用 SMS Retriever API，我遵循了本教程Tutorial_Link。我正确地遵循了所有步骤。只是我使用的作弊码：我从客户端而不是服务器发送和验证 OTP SMS。我正在接收短信，但我的广播接收器无法检测到短信。为什么？
一次性密码：
String message = "<#> otp code: "+otp+" XkvuQVe6yfP";
请帮助我，我从过去三天就卡在这里......这是我的代码：

LocalBroadcastManager.getInstance(this).unregisterReceiver(smsBroadcast)
ed_otp.setText("Your OTP is: $otp")
