[BUG] FileNotFoundException when addBitmapToCache

📝 Describe the Bug

I found the crash report looks like this:

java.io.FileNotFoundException: /data/user/0/com.myapp.www/cache/___pdf___cache___/0: open failed: ENOENT (No such file or directory)

Unable to reproduce it, but seems like it would be possible to access the cache folder /___pdf___cache___ cache has been deleteRecursively().

Since the task to add bitmap to cache will be run on the IO thread, there's no guarantee that the cacheDir will exist when it executes.

The solution might be to check the cacheDir exists before proceeding, but not sure if I have missed anything.
