这是我的清单

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.borisruzanov.social">

    <uses-permission android:name="android.permission.INTERNET"/>
    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"

        android:theme="@style/AppTheme">
        <activity android:name=".AuthPage">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".GoogleSignInActivity" >
        </activity>
        <activity android:name=".PhoneAuthActivity" >
        </activity>

        <activity android:name=".FacebookLoginActivity"
            >
            <meta-data android:name="com.facebook.sdk.ApplicationId"
                android:value="@string/facebook_app_id"/>
        </activity>

        <activity android:name="com.facebook.FacebookActivity"
            android:configChanges=
                "keyboard|keyboardHidden|screenLayout|screenSize|orientation"
            android:label="@string/app_name" />
        <activity
            android:name="com.facebook.CustomTabActivity"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
                <data android:scheme="@string/fb_login_protocol_scheme" />
            </intent-filter>
        </activity>
    </application>

</manifest>

而且我也不明白为什么SDK的初始化不是实际的并且它被描述。我已经尝试过堆叠的解决方案。没有帮助。

此外，如果any1知道Firebase和Facebook auth集成良好的好例子吗？因为总是火柱引导完全崩溃了我的大脑。

Answer 1

您需要添加

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    //initialize Facebook SDK
    FacebookSdk.sdkInitialize(getApplicationContext());
    if (BuildConfig.DEBUG) {
        FacebookSdk.setIsDebugEnabled(true);
        FacebookSdk.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);
    }

    setContentView(R.layout.activity_main); }

需要向应用程序添加元数据

<application android:label = "@string/app_name" ... > 
    ...
    <meta-data android:name = "com.facebook.sdk.ApplicationId" android:value = "@string/facebook_app_id" />  
    ...
</ application>

而不是

<activity android:name=".FacebookLoginActivity"
    >
    <meta-data android:name="com.facebook.sdk.ApplicationId"
        android:value="@string/facebook_app_id"/>
</activity>

Answer 2

您不需要在自动初始化时手动初始化FacebookSDK，只需更改您的清单文件，如@Boris所示。希望它现在可以运作。
