Create an MMKV instance with an unique ID (in single-process mode). @param mmapID The unique ID of the MMKV instance. @throws RuntimeException if the

@return All the keys.

@return The root folder of MMKV, defaults to $(FilesDir)/mmkv.

@return The total count of all the keys.

Clear all the key-values inside the MMKV instance. The data file will be trimmed down to `pageSize`, and some sync operations will be called If you do

Check whether or not MMKV contains the key. @param key The key of the value.

Call this method if the MMKV instance is no longer needed in the near future. Any subsequent call to any MMKV instances with the same ID is undefined

SetString string value should be utf-8 encoded

Get the actual used size of the MMKV instance. This size might increase and decrease as MMKV doing insertion and full write back.

Clear memory cache of the MMKV instance. You can call it on memory warning. Any subsequent call to the MMKV instance will trigger all key-values loadi
