1. Obtain the cache size and clear the cache

All data paths in the application:

/Data/com. xxx. xxx/cache-in-app cache (Note: Corresponding Method getCacheDir ())

/Data/com. xxx. xxx/databases-in-app Database

2. Application rating

/*** Open the App Store * @ param packageName */private void openAppMarket (String packageName) {try {String str = "market: // detail? Id = "+ packageName; Intent intent = new Intent (Intent. ACTION_VIEW); intent. setData (Uri. parse (str); startActivity (intent);} catch (Exception e) {ToastUtil. show (getActivity (), R. string. open_app_market_failed); e. printStackTrace (); // String url = "https://github.com/myxh"; Intent intent = new Intent (Intent. ACTION_VIEW); intent. setData (Uri. parse (url); startActivity (intent );}}
