Android 应用程序中的 Facebook 和 Google 身份验证

Question

我正在尝试为我的移动应用程序集成 Facebook 和 Google 身份验证。我已经按照 Google 和 Facebook 教程学习如何操作，两个项目在分开时都能正常工作。在我当前的解决方案中，使用 Google 登录工作正常，但 Facebook 给我以下错误消息：

Permission Denial: get/set setting for user asks to run as user -2 but is calling from user 0; this requires android.permission.INTERACT_ACROSS_USERS_FULL

E/Parcel: Class not found when unmarshalling: com.facebook.login.LoginClient$Request

Caused by: java.lang.NoClassDefFoundError: com/facebook/login/LoginClient$Request

Caused by: java.lang.ClassNotFoundException: Didn't find class "com.facebook.login.LoginClient$Request" on path

这是我的 LoginAvtivity class 我用于身份验证：

public class ActivityLogin extends AppCompatActivity implements GoogleApiClient.OnConnectionFailedListener, View.OnClickListener {

private static final String TAG = "SignInActivity";
private static final int RC_SIGN_IN = 9001;

private GoogleApiClient mGoogleApiClient;
private ProgressDialog mProgressDialog;

private LoginButton facebookButton;
private CallbackManager facebookCallbackManager;

@Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(getApplicationContext());
    facebookCallbackManager = CallbackManager.Factory.create();
    setContentView(R.layout.activity_login);




    // Button listeners
    findViewById(R.id.google_button).setOnClickListener(this);
    facebookButton = (LoginButton)findViewById(R.id.facebook_button);

    // [START configure_signin]
    // Configure sign-in to request the user's ID, email address, and basic
    // profile. ID and basic profile are included in DEFAULT_SIGN_IN.
    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestEmail()
            .requestIdToken(getString(R.string.server_client_id))
            .build();

    // [START build_client]
    // Build a GoogleApiClient with access to the Google Sign-In API and the
    // options specified by gso.
    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .build();

    // [START customize_button]
    // Customize sign-in button. The sign-in button can be displayed in
    // multiple sizes and color schemes. It can also be contextually
    // rendered based on the requested scopes. For example. a red button may
    // be displayed when Google+ scopes are requested, but a white button
    // may be displayed when only basic profile is requested. Try adding the
    // Scopes.PLUS_LOGIN scope to the GoogleSignInOptions to see the
    // difference.
    SignInButton signInButton = (SignInButton) findViewById(R.id.google_button);
    signInButton.setSize(SignInButton.SIZE_STANDARD);
    signInButton.setScopes(gso.getScopeArray());

    setGooglePlusButtonText(signInButton, "Sign in with Google");

    facebookButton.registerCallback(facebookCallbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            Intent intent = new Intent(ActivityLogin.this, MainActivity.class);
            startActivity(intent);
        }

        @Override
        public void onCancel() {
            Log.d("TOKEN", "Canceled!!!!!!!!!!");

        }

        @Override
        public void onError(FacebookException error) {
            Log.d("TOKEN", "CHUUUUUUJ WIELKI!!!!!!!!!!!!");

        }
    });

@Override

    super.onStart();

    OptionalPendingResult<GoogleSignInResult> opr = Auth.GoogleSignInApi.silentSignIn(mGoogleApiClient);

        // and the GoogleSignInResult will be available instantly.
        Log.d(TAG, "Got cached sign-in");
        GoogleSignInResult result = opr.get();
        handleSignInResult(result);
    } else {
        // If the user has not previously signed in on this device or the sign-in has expired,
        // this asynchronous branch will attempt to sign in the user silently.  Cross-device
        // single sign-on will occur in this branch.
        showProgressDialog();
        opr.setResultCallback(new ResultCallback<GoogleSignInResult>() {
            @Override
            public void onResult(GoogleSignInResult googleSignInResult) {
                hideProgressDialog();
                handleSignInResult(googleSignInResult);
            }
        });
    }
}

// [START onActivityResult]
@Override

        //mStatusTextView.setText(getString(R.string.signed_in_fmt, acct.getDisplayName()));

        Intent intent = new Intent(ActivityLogin.this, MainActivity.class);
        startActivity(intent);

        String idToken = acct.getIdToken();

// [END signIn]



@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
    // An unresolvable error has occurred and Google APIs (including Sign-In) will not
    // be available.
    Log.d(TAG, "onConnectionFailed:" + connectionResult);
}

private void showProgressDialog() {
    if (mProgressDialog == null) {
        mProgressDialog = new ProgressDialog(this);
        mProgressDialog.setMessage(getString(R.string.loading));
        mProgressDialog.setIndeterminate(true);
    }

    mProgressDialog.show();
}

    if (mProgressDialog != null && mProgressDialog.isShowing()) {
        mProgressDialog.hide();

}

@Override

    switch (v.getId()) {
        case R.id.google_button:
            signIn();
            break;
        case R.id.tutorial:
            Intent intent = new Intent(this, TutorialActivity.class);
            startActivity(intent);
            break;
//            case R.id.disconnect_button:
//                revokeAccess();
//                break;
    }
}

protected void setGooglePlusButtonText(SignInButton signInButton, String buttonText) {
    // Find the TextView that is inside of the SignInButton and set its text
    for (int i = 0; i < signInButton.getChildCount(); i++) {
        View v = signInButton.getChildAt(i);

        if (v instanceof TextView) {
            TextView tv = (TextView) v;
            tv.setText(buttonText);
            return;
        }
    }
  }
}

这是 class 的 xml 布局：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".ActivityLogin"
android:background="@drawable/background_gradient">

<com.facebook.login.widget.LoginButton
    android:id="@+id/facebook_button"
    android:layout_width="200dp"
    android:layout_height="40dp"
    android:layout_above="@+id/google_button"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="20dp" />

<com.google.android.gms.common.SignInButton
    android:id="@+id/google_button"
    android:layout_width="200dp"
    android:layout_height="40dp"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="60dp"
    />

我似乎在这里遗漏了一些重要的东西，但我找不到它是什么。第一条错误消息说我缺少权限，但根据 google 和 facebook 教程，不需要此特定权限。

Answer 1

您没有在 onActivityResult() 方法中处理 Facebook 结果。

将此添加到您的方法中 -

@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);
        handleSignInResult(result);
    } 
    else{
        //Add this to handle Facebook result
        facebookCallbackManager.onActivityResult(requestCode, resultCode, data);
    }
}
