java.lang.IllegalStateException: Fragment already added异常的处理

在Fragment中注册BroadcastReceiver时，触发广播会发生 java.lang.IllegalStateException: Fragment already added

在注册BroadcastReceiver时，添加

filter.addAction(Intent.ACTION_PACKAGE_ADDED);filter.addAction(Intent.ACTION_PACKAGE_REMOVED);filter.addAction(Intent.ACTION_PACKAGE_REPLACED);

就OK了
