Facebook android shareDialog closes after opening

Question

Following THIS I'm using facebook sdk in my android application and for test I've added below code to my MainActivity:

CallbackManager callbackManager;
ShareDialog shareDialog;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(getApplicationContext());
    setContentView(R.layout.activity_main);

    callbackManager = CallbackManager.Factory.create();
    shareDialog = new ShareDialog(this);

    if (ShareDialog.canShow(ShareLinkContent.class)) {
        ShareLinkContent linkContent = new ShareLinkContent.Builder()
                .setContentTitle("Hello Facebook")
                .setContentDescription(
                        "The 'Hello Facebook' sample  showcases simple Facebook integration")
                .setContentUrl(Uri.parse("http://developers.facebook.com/android"))
                .build();

        shareDialog.show(linkContent);
    }
}

and I've added the following steps in my manifest:

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

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

<provider android:authorities="com.facebook.app.FacebookContentProvider950310748347640"
  android:name="com.facebook.FacebookContentProvider"
  android:exported="true" />

<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" />

and when I test the shareDialog pops up and suddenly it closes itself.

You need to make your app "Public".

Go to the "Status and Review" section in your app settings, and turn on the option "Do you want to make this app and all its live features available to the general public?"
