The is the old free version of Hanping Chinese Dictionary. It is only useful to people running Android 2.2 or earlier.
If your Android device is running Android 2.3 Gingerbread (or higher) you will most probably want to install the new Hanping Chinese Dictionary Lite app (and uninstall this Classic app if necessary). You can also keep both apps installed at the same time, if you wish. But it is probably a good idea to close (Force Stop) one app before opening the other.
The version on Google Play and Amazon Appstore is only available to devices running Android 2.2 (Froyo) and earlier. If you are running a later version of Android and still wish to run this Classic app, then you can download it here.
Many thanks for your support.
