关于跨进程使用 getSharedPreferences 的问题

?

public static final int?MODE_MULTI_PROCESS

SharedPreference loading flag: when set, the file on disk will be checked for modification even if the shared preferences instance is already loaded in this process. This behavior is sometimes desired in cases where the application has multiple processes, all writing to the same SharedPreferences file. Generally there are better forms of communication between processes, though.

This was the legacy (but undocumented) behavior in and before Gingerbread (Android 2.3) and this flag is implied when targetting such releases. For applications targetting SDK versions?greater than?Android 2.3, this flag must be explicitly set if desired.
