将您的清单文件更改为：

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

    <uses-sdk android:minSdkVersion="22" android:targetSdkVersion="22" />

    <uses-permission android:name="android.permission.VIBRATE" />
    <uses-permission android:name="android.permission.BLUETOOTH" />
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.NETWORK" />

Answer 2

因为您的应用程序库获得了65k dex限制。通常android应用程序库有65k dex限制。但是在释放果冻豆后，他们会得到这个限制的支持。 Check this（com.android.support:multidex:1.0.0）

dependencies {
  compile 'com.android.support:multidex:1.0.0'
}

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.android.multidex.myapplication">
    <application
        ...
        android:name="android.support.multidex.MultiDexApplication">
        ...
    </application>
</manifest>

public void onCreate(Bundle arguments) {
    MultiDex.install(getTargetContext());
    super.onCreate(arguments);
    ...
}

如果您使用的是eclips，则需要下载此lib并在应用程序类中添加Multi dex类。

ClassNotFoundException：未在路径上找到类：DexPathList
