Hanping Chinese Dictionary Pro 3.7.0 introduced a brand new Clipboard Monitoring feature to make it super quick to look up Chinese words from whichever app you happen to be using. In many cases, not only will you be able to stay in whichever app you are using, but also you may not even need to bring down the Notification Shade, because the heads-up notification will show up for a brief (long enough) period of time, allowing you to see the dictionary definition.
IMPORTANT NOTE 2019: Android Q (and later) do not allow apps to monitor the clipboard, so this feature will not work on such devices
There are some important points worth mentioning:
This feature is entirely optional, can be manually triggered (from Hanping Dictionary's left navigation drawer), and can be automatically triggered at System Startup
If you opt to trigger this feature at System Startup, it will add almost nothing to your device's startup time
Even when Clipboard Monitoring is running in the background, it has been designed to use virtually no battery or CPU power, and only 3MB-7MB memory which is negligible
The app now requests a "run at startup" permission allowing Hanping to start Clipboard Monitoring when your device starts up, should you configure it to do so
The notification is persistently shown in Android's Notification Shade. This is the standard way for continuously running features on Android. On the plus side, this persistent notification can be used as a quick launcher for the Hanping Dictionary and Hanping Camera apps
You get an expanded notification when you copy long text showing all the words (up to the first eight). If there are more than 8 words then you will see a "(+X more)" message in the bottom right. If you want to see all the words, simply click on the notification to bring up Hanping. You can also click on the Hanzi in the left of the notification to bring up individual words
Actually, a more significant problem I discovered is that when you star a word through the pop-up or through clipboard monitoring, then export the list as a text file, the word definition is missing.
Ah yes, I noticed that too a couple of weeks ago. Already fixed, so will also be in the next update, which will be ready sometime this month if all goes according to plan!
