android - 使用 Android Studio 和 Facebook 4.6.0 扩展类 com.facebook.login.widget.LoginButton 时出错

Question

在我的 build.gradle 中，我正在导入 Facebook:

compile 'com.facebook.android:facebook-android-sdk:4.6.0'

在我的应用程序类中，我正在初始化 Facebook SDK:

FacebookSdk.sdkInitialize(getApplicationContext());

在我的 AndroidManifest.xml 中:

         <activity
        android:name="com.facebook.FacebookActivity"
        android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.Translucent.NoTitleBar" />

    <receiver android:name="com.greenrobot.pirates.HelloFacebookBroadcastReceiver" />

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

这适用于 Genymotion。在我的设备上，我收到一条错误消息，提示它无法为类(class)充气。

带有登录按钮的xml文件是:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

 <com.facebook.login.widget.LoginButton
     xmlns:facebook="http://schemas.android.com/apk/res-auto"
    android:id="@+id/login_button"
    android:layout_width="400dp"
    android:layout_height="500dp"
    android:layout_marginBottom="30dp"
    android:layout_marginTop="30dp"
    android:src="@drawable/login_button" />


     </LinearLayout>

Answer 1

事实证明，我启用了 multidex，它在 5.x(模拟器)上运行，但在 4.x(我的设备)上运行。添加 multidex 支持库后，它开始正常工作。
