Question

我正在使用此代码使用Firebase进行sigin。

private void signIn() {
    Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
    startActivityForResult(signInIntent, RC_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 == RC_SIGN_IN) {
        GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
        if (result.isSuccess()) {
            // Google Sign In was successful, authenticate with Firebase
            GoogleSignInAccount account = result.getSignInAccount();
            firebaseAuthWithGoogle(account);
        } else {
            Toast.makeText(SignIn.this, "Authentication Went wrong ", Toast.LENGTH_SHORT).show();
        }
    }
}

private void firebaseAuthWithGoogle(GoogleSignInAccount account) {
    AuthCredential credential = GoogleAuthProvider.getCredential(account.getIdToken(), null);
    mAuth.signInWithCredential(credential)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    if (task.isSuccessful()) {
                        // Sign in success, update UI with the signed-in user's information
                        Log.d("TAG", "signInWithCredential:success");
                        FirebaseUser user = mAuth.getCurrentUser();
                        //updateUI(user);
                    } else {
                        // If sign in fails, display a message to the user.
                        Log.w("TAG", "signInWithCredential:failure", task.getException());
                        Toast.makeText(SignIn.this, "Authentication failed.",
                                Toast.LENGTH_SHORT).show();
                        //updateUI(null);
                    }

                    // ...
                }
            });

}

} 但是当我尝试登录时它会给出错误。类似身份验证失败。我在哪里做错了？

我在我的应用Gradle中包含了firebaseAuth的两个依赖项 compile 'com.google.firebase:firebase-auth:11.0.2' compile 'com.google.android.gms:play-services-auth:11.0.2' 并且还在我的Firebase控制台中启用了Google作为SignIn方法。

在我的logout.class我正在使用此代码`按钮=（按钮）findViewById（R.id.logout）; mAuth = FirebaseAuth.getInstance（）;

    mAuthlistener = new FirebaseAuth.AuthStateListener() {
        @Override
        public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
            if (firebaseAuth.getCurrentUser() == null) {
                startActivity(new Intent(logout.this, SignIn.class));
            }
        }
    };

    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            mAuth.signOut();
        }
    });
}`

但是当我点击它然后打开Sigin.class但是当我们再次尝试Sigin时它会崩溃。

确保在Firebase控制台中创建Firebase项目时使用已添加的SHA1证书到Firebase项目并尝试使用我的以下代码

with open('/home/adiel/log', 'r') as f:
    for line in f:
        line = line.split()
        if line[6] in {'443', '65535'} and line[4] in {'172.18.0.5'} :
            print(line[3:7])
        elif line[6] in {'443', '65535'} and line[4] in {'172.18.0.37'}:
            print(line[3:7])

让我知道它是否有效。

表示LOgOUt 你必须像我在我的项目中那样完成BottomNavigation布局。下面是xml代码。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="com.food.sheenishere.stark.profilemain">



    <android.support.design.widget.BottomNavigationView
        android:id="@+id/navigation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:background="?android:attr/windowBackground"
        app:menu="@menu/navigation" />

</LinearLayout>

这是Java代码。

package com.food.sheenishere.stark;


import android.app.ProgressDialog;

import android.content.Intent;

import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.design.widget.BottomNavigationView;

import android.view.MenuItem;


import android.view.View;

import android.widget.ListView;

import android.widget.Toast;

import java.util.ArrayList;

public class profilemain extends AppCompatActivity {
    private FirebaseAuth mAuth;
    private FirebaseAuth.AuthStateListener mAuthListener;





    private BottomNavigationView.OnNavigationItemSelectedListener
            mOnNavigationItemSelectedListener
            = new BottomNavigationView.OnNavigationItemSelectedListener() {

        @Override
        public boolean onNavigationItemSelected(@NonNull MenuItem item) {
            switch (item.getItemId()) {
                case R.id.navigation_home:

                    Toast.makeText(profilemain.this, "hi hello", Toast.LENGTH_SHORT).show();
                    return true;
                case R.id.navigation_dashboard:
                    Toast.makeText(profilemain.this, "hi hello", Toast.LENGTH_SHORT).show();
                    return true;
                case R.id.navigation_notifications:
                    Toast.makeText(profilemain.this, "hi hello", Toast.LENGTH_SHORT).show();
                    return true;
                case R.id.navigation_signout:

                    Toast.makeText(profilemain.this, "You have successfully Signed out", Toast.LENGTH_SHORT).show();
                    mAuth.signOut();
                    return true;
            }
            return false;
        }

    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_profilemain);





        BottomNavigationView navigation = (BottomNavigationView) findViewById(R.id.navigation);
        navigation.setOnNavigationItemSelectedListener(mOnNavigationItemSelectedListener);
        mAuth = FirebaseAuth.getInstance();


        mAuthListener = new FirebaseAuth.AuthStateListener() {
            @Override
            public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
                if (firebaseAuth.getCurrentUser() == null) {
                    startActivity(new
                            Intent(profilemain.this, MainActivity.class));

                }
            }
        };


    }

    @Override
    protected void onStart() {
        super.onStart();

        mAuth.addAuthStateListener(mAuthListener);
    }
}
