应用程序在模拟器上运行正常，但在我的设备上运行时无法登录/注册

Question

I don't have much information to provide as I have no idea what the problem is. It works just fine when I run it on the emulator but when I try to run it on my device I can't get past the login/register. This is my login code, pretty straight forward and the register is pretty much the same so I won't bother to post it:

class LoginActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_login)

        login_button.setOnClickListener {

            performLogin()

        }

    }


    fun backToRegistration (view : View) {
        val registerIntent = Intent (this, RegisterActivity::class.java)
        startActivity(registerIntent)
    }

    private fun performLogin(){

        val logEmail = login_email.text.toString()
        val logPass = login_password.text.toString()

        Log.d("Main", "email is $logEmail")
        Log.d("Main", "pass is $logPass")

//        Patterns.EMAIL_ADDRESS.matcher(logEmail).matches()  <--- this method was used before for the if statement but I've replaced it as I kept getting the invalid email error for some reason.

        if (logEmail.contains("@") && logEmail.contains(".")) {

            if (logPass.length > 5) {

                FirebaseAuth.getInstance().signInWithEmailAndPassword(logEmail, logPass).addOnCompleteListener {
                    if (it.isSuccessful) {
                        Log.d("Login", "Successfully logged a user in using uid: ${it.result?.user?.uid}")
                        val intent = Intent(this, MainActivity::class.java)
                        intent.flags = Intent.FLAG_ACTIVITY_CLEAR_TASK.or(Intent.FLAG_ACTIVITY_NEW_TASK)
                        startActivity(intent)
                        return@addOnCompleteListener
                    }
                    //else if successful
                    Log.d("Login", "Failed to log in a user")

                }.addOnFailureListener {
                    Log.d("Main", "Failed to create user : ${it.message}")
                }
            } else {
                Toast.makeText(this, "Your password needs to be at least 6 characters long", Toast.LENGTH_LONG)
                    .show()
            }


        } else {
            Toast.makeText(this, "Please enter a valid email address", Toast.LENGTH_LONG).show()
        }

    }


}

This is my logcat (level set to error) right after I attempt a login:

Answer 1

To anyone facing the same issue here are two possible solutions, based on your situation.

1. If your app is on the app store and you're having that issue, refer to the answer posted here Thank you @Swati for referring it to me.

2. If you are just trying to run it on your phone for testing and, make sure that you've provided the SHA certificate fingerprints in your Firebase project. If you're not sure what that means, go to your project settings -> General and SHA certificate fingerprints should be under "Your apps".

You will need to enter both SHA-1 & SHA-256

To get them go to your Android project and click the "Gradle" tab on the almost-top right corner of the window (using windows, not sure about mac).

Then navigate to your project -> :app -> Tasks -> android and double click the "signingReport".

It should run some lines at the bottom of your window where your log cat is usually and in them you would find both SHA-1 and SHA-256
