在firebase facebook登录上获取身份验证失败
在firebase facebook登录上获取身份验证失败
提问于 2017-11-13 13:46:01
我正在开发firebase演示应用程序，我添加了firebase facebook和google登录，所以google运行良好，但是每当我尝试使用facebook登录时，它就会在运行时抛出Authentication failed，所以我将尝试所有的stackOverflow解决方案，但它没有工作，所以有人知道如何解决这个问题吗？
下面的是我的登录代码：-
public class SplashScreen extends AppCompatActivity implements GoogleApiClient.OnConnectionFailedListener {
//constant values
public static final String USER_NAME="com.gaurav.javascripttutorial.username";
public static final String USER_IMAGE="com.gaurav.javascripttutorial.userimage";
public static final String USER_ID="com.gaurav.javascripttutorial.userid";
int RC_SIGN_IN = 1000;
//Firebase
FirebaseAuth mAuth;
GoogleApiClient mGoogleApiClient;
CallbackManager mCallbackManager;
//views
private SignInButton googleLogin;
private LoginButton facebookLogin;
private ProgressDialog dialog;
//Shared Preference
SharedPreferences pref;
SharedPreferences.Editor editor;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.setApplicationId(getString(R.string.fb_app_id));
FacebookSdk.sdkInitialize(getApplicationContext());
setContentView(R.layout.main_splashscreen);
googleLogin = (SignInButton) findViewById(R.id.googleLogin);
facebookLogin = (LoginButton) findViewById(R.id.facebookLogin);
pref = this.getSharedPreferences("user",0);
editor = pref.edit();
dialog = new ProgressDialog(this);
dialog.setMessage("Loading, Please wait....");
//Google configuration
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken(getString(R.string.default_web_client_id))
.requestEmail()
.requestProfile()
.build();
mGoogleApiClient = new GoogleApiClient.Builder(this)
.enableAutoManage(this, this)
.addApi(Auth.GOOGLE_SIGN_IN_API,gso)
.build();
//Facebook configuration
mCallbackManager = CallbackManager.Factory.create();
mAuth = FirebaseAuth.getInstance();
if (mAuth.getCurrentUser()!= null){
FirebaseUser user = mAuth.getCurrentUser();
editor.clear();
editor.putString(USER_NAME,user.getDisplayName());
editor.putString(USER_ID, user.getUid());
editor.putString(USER_IMAGE, user.getPhotoUrl().toString());
editor.commit();
Intent intent = new Intent(SplashScreen.this, MainActivity.class);
startActivity(intent);
finish();
}
googleLogin.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
googleSignIn();
}
});
facebookLogin.setReadPermissions("email","public_profile");
facebookLogin.registerCallback(mCallbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
handleFacebookAccessToken(loginResult.getAccessToken());
}
@Override
public void onCancel() {
Toast.makeText(SplashScreen.this, "Facebook login cancel.", Toast.LENGTH_LONG).show();
}
@Override
public void onError(FacebookException error) {
Toast.makeText(SplashScreen.this, "Something went wrong! Please try again", Toast.LENGTH_LONG).show();
}
});
}
private void googleSignIn(){
Intent intent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(intent,RC_SIGN_IN);
}
private void handleFacebookAccessToken(AccessToken token){
final AuthCredential credential = FacebookAuthProvider.getCredential(token.getToken());
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
FirebaseUser user = mAuth.getCurrentUser();
editor.clear();
editor.putString(USER_NAME,user.getDisplayName());
editor.putString(USER_ID, user.getUid());
editor.putString(USER_IMAGE, user.getPhotoUrl().toString());
editor.commit();
Intent intent = new Intent(SplashScreen.this, MainActivity.class);
startActivity(intent);
finish();
dialog.dismiss();
} else {
// If sign in fails, display a message to the user.
Toast.makeText(SplashScreen.this, "Authentication failed.", Toast.LENGTH_LONG).show();
}
}
});
}
private void firebaseAuthWithGoogle(GoogleSignInAccount account){

假设您已经正确配置了一切(否则，读文档)，这对我来说很好(Kotlin代码，对不起)。如果您需要Java，只需翻译)：
我的Activity扩展了AppCompatActivity
class ActivityLogin : AppCompatActivity() {
private val callbackManager: CallbackManager = CallbackManager.Factory.create()
private val mAuth: FirebaseAuth = FirebaseAuth.getInstance()
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.main_splashscreen)
loginButton.setReadPermissions("email", "public_profile")
loginButton.registerCallback(callbackManager, object : FacebookCallback<LoginResult> {
override fun onSuccess(result: LoginResult) {
handleFacebookAccessToken(result.accessToken)
}
override fun onCancel() {
Toast.makeText(this@ActivityLogin, "Facebook Authentication canceled.", Toast.LENGTH_SHORT).show()
}
override fun onError(error: FacebookException?) {
Toast.makeText(this@ActivityLogin, "Facebook Authentication failed.", Toast.LENGTH_SHORT).show()
}
})
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent) {
super.onActivityResult(requestCode, resultCode, data)
callbackManager.onActivityResult(requestCode, resultCode, data)
}
private fun handleFacebookAccessToken(token: AccessToken) {
val credential = FacebookAuthProvider.getCredential(token.token)
mAuth.signInWithCredential(credential)
.addOnCompleteListener(this) { task ->
if (task.isSuccessful) {
val mainIntent = Intent(this@ActivityLogin, ActivityFeed::class.java)
startActivity(mainIntent)
finish()
} else {
Toast.makeText(this@ActivityLogin, "Firebase Authentication failed.", Toast.LENGTH_SHORT).show()
}
}
}
}如你所见，没有必要打电话给
FacebookSdk.setApplicationId(getString(R.string.fb_app_id));
FacebookSdk.sdkInitialize(getApplicationContext());在你的活动的onCreate()。
