    @Override

我gradle這個建立

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 22 
    buildToolsVersion "22.0.1" 

    defaultConfig { 
     applicationId "com.example.nan.spymap" 
     minSdkVersion 21 
     targetSdkVersion 22 
     versionCode 1 
     versionName "1.0" 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
} 
repositories { mavenCentral() } 

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    compile 'com.facebook.android:facebook-android-sdk:4.6.0' 
}

它說什麼是錯的堆棧跟蹤：之後的佈局XML加載

Caused by: The SDK has not been initialized, make sure to call FacebookSdk.sdkInitialize() first.

初始化完成（在的setContentView（））。

在應用程序類之前或之中初始化SDK。

但我確實; FacebookSdk.sdkInitialize（getApplicationContext（））; – NicklasN

保護無效onCreate（Bundle savedInstanceState）{ super.onCreate（savedInstanceState）; setContentView（R.layout.activity_main）; FacebookSdk.sdkInitialize（getApplicationContext（））; callbackManager = CallbackManager.Factory.create（）; setContentView（R.layout.activity_main）; – NicklasN

我通過將初始化作爲第一件事來實現它！ :) – NicklasN
