Я пытаюсь реализовать facebook login в своем приложении. Тем не менее каждый раз, когда я запускаю приложение он бросает эту ошибку:android Facebook login error: null package
01-05 17:06:48.986 27804-27804/sidd.tisb.lms.sidsstudios.maatra17 E/LoginFragment﹕ Cannot call LoginFragment with a null calling package. This can occur if the launchMode of the caller is singleInstance.
Вот мой androidManifest, я поставил launchMode стандарту:
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.GET_ACCOUNTS"/>
<meta-data
android:name="com.facebook.sdk.Application"
android:value="@string/app_id"/>
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.facebook.FacebookActivity"
android:label="@string/app_name"
android:launchMode="standard"
>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Наконец вот моя mainActivity. Я также внедрил логин Google ранее, который отлично работает. Я опровергаю, если код запутан. Я собираюсь этого нужно просто вставить всю активность:

Я посмотрел на другие решения на StackOverflow, но ни один из них не похоже на работу для меня. Любые идеи, как я могу это решить. Спасибо, парни!!!
