Android上的Facebook登录按钮

Question

我尝试在我的项目上添加一个Facebook登录按钮，但是当我测试错误日志时，请向我显示： 致命异常：主登录尝试失败：FacebookActivity无法启动。请确保您已将FacebookActivity添加到AndroidManifest。 但我已经把FacebookActivity的清单如下图所示：

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


<uses-permission android:name="android.permission.INTERNET" /> 

<application 
    android:allowBackup="true" 
    android:icon="@mipmap/ic_launcher" 
    android:label="@string/app_name" 
    android:theme="@style/AppTheme" > 
    <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id"/> 
    <activity 
     android:name=".ActivityNuevoUsuario" 
     android:label="@string/app_name" > 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 
</application> 
<activity android:name=".ActivityLogueo" 
    android:label="@string/app_name" 
    android:screenOrientation="portrait"> 
</activity> 
<activity android:name=".ActivityPrincipal" 
    android:label="@string/app_name" 
    android:screenOrientation="portrait"> 
</activity> 
<activity android:name="com.facebook.FacebookActivity" 
    android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation" 
    android:theme="@android:style/Theme.Translucent.NoTitleBar" 
    android:label="@string/app_name" /> 

我需要别人的许可？

你把应用程序标记以外的活动，更正后的清单应该是：

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


<uses-permission android:name="android.permission.INTERNET" /> 

<application 
    android:allowBackup="true" 
    android:icon="@mipmap/ic_launcher" 
    android:label="@string/app_name" 
    android:theme="@style/AppTheme" > 
    <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id"/> 

    <activity 
     android:name=".ActivityNuevoUsuario" 
     android:label="@string/app_name" > 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 
    <activity android:name=".ActivityLogueo" 
     android:label="@string/app_name" 
     android:screenOrientation="portrait"> 
    </activity> 
    <activity android:name=".ActivityPrincipal" 
     android:label="@string/app_name" 
     android:screenOrientation="portrait"> 
    </activity> 
    <activity 
     android:name="com.facebook.FacebookActivity" 
     android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation" 
     android:theme="@android:style/Theme.Translucent.NoTitleBar" 
     android:label="@string/app_name" /> 
</application>
