我在我的Android应用程序中使用Facebook，它运行得很好。
然而，我意识到当我每次使用“确定”和“取消”选项说“您已经授权使用此应用程序”时，会出现无用的屏幕。
如何从我的应用中避开或删除此屏幕。
我在谷歌上搜索过，我找到了旧版Facebook SDK的答案但是如何使用新的Facebook SDK（3.0及以上版本）实现它？
这是我的代码，
public void onClick(View v)
{
Bundle myParams = new Bundle();
myParams.putString("message", " DOWNLOAD THE 'Saragama' ANDROID APP FROM " + url_android.toString()
+ ". Fully integrated with Facebook and Twitter.");
myParams.putString("name", mSharingText.getText().toString());
myParams.putString("caption", "www.saragama.com");
myParams.putString("description", "Various religios music, chants, mantras, christian songs, islamic music, quran and more on saragama");
myParams.putString("link", "http://android.saragama.com");
myParams.putString("picture", albumImageURL);

在facebook sdk 4.0中尝试激活和停用onResume和onPause中的应用程序，如下所示：
@Override
protected void onResume() {
super.onResume();
// update your UI
// Logs 'install' and 'app activate' App Events.
AppEventsLogger.activateApp(this);
}
@Override
protected void onPause() {
super.onPause();
// Logs 'app deactivate' App Event.
AppEventsLogger.deactivateApp(this);
}
