Helper class for performing atomic operations on a file by creating a backup file until a write has successfully completed. If you need this on older versions of the platform you can use NoType:android/support/v4/util/AtomicFile;Href=../../../reference/android/support/v4/util/AtomicFile.html in the v4 support library.

Atomic file guarantees file integrity by ensuring that a file has been completely written and sync'd to disk before removing its backup. As long as the backup file exists, the original file is considered to be invalid (left over from a previous attempt to write the file).

Atomic file does not confer any file locking semantics. Do not use this class when the file may be accessed or modified concurrently by multiple threads or processes. The caller is responsible for ensuring appropriate mutual exclusion invariants whenever it accesses the file.
