Getcachedir () and Getfilesdir () are often used when saving the cache (file), which returns the default result as/data/data/package name/cache (files).

However, this can be very internal Storage, and automatically clears the contents of the cache directory when internal Storage tense.

At this point, consider to save the file in external strorage, become a feasible scheme;

Two types of positions:

1./sdcard/android/data/Package name/cache (files)

Similar to/data/data/package name/cache (files), just move to external Storage, clear the cache in application management, will kill the corresponding file directory and content, uninstall the application will be automatically cleared;

2./sdcard/the Custom Directory

Unless manually removed in file management, it will persist;

Choose according to different needs;
