通过点击通知，我发布PendingIntent，这是对参数的意图;
在MyActivity中，我得到了这个意图并将其传递给方法onNewIntent(getIntent());
在这个方法中，我取出我的参数，并根据它们来执行操作。
问题是当应用程序关闭或打开时 - 调用方法并且一切正常。但是如果应用程序最小化，则按下通知错误输出。
public class MyActivity extends ActionBarActivity implements NavigationDrawerFragment.NavigationDrawerCallbacks {
...
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
...
onNewIntent(getIntent());
}
...
@Override
public void onNewIntent(Intent intent) {
FragmentManager fragmentManager = getSupportFragmentManager();
Bundle arguments;
Fragment fragment;
String guest;
Bundle extras = intent.getExtras();
if (extras != null) {
if (extras.containsKey("group_id")) {
int msg = extras.getInt("group_id");
String hotel = extras.getString("hotel");
switch (msg) {
case 5:
fragment = new PagerLogbookContainer();
arguments = new Bundle();
arguments.putString(ARGUMENT_PAGE_HOTEL, hotel);
fragment.setArguments(arguments);
fragmentManager.popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE);
fragmentManager.beginTransaction().replace(R.id.container, fragment).commit();
setTitle(hotel);
break;
case 1:
guest = extras.getString("guest");
String room = extras.getString("room");
fragment = new Guest();
arguments = new Bundle();
arguments.putString("guestid", guest);
arguments.putString("hotel", hotel);
arguments.putString("room", room);
fragment.setArguments(arguments);
fragmentManager.popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE);
fragmentManager.beginTransaction().replace(R.id.container, fragment, "guest").commit();
break;
case 4:
guest = extras.getString("guest");
fragment = new Survey();
arguments = new Bundle();
arguments.putString("guestid", guest);
arguments.putString("hotel", hotel);
