Android 7.0設置MODE_WORLD_READABLE出現異常解決方法

Android 7.0給SharedPreferences設置Context.MODE_WORLD_READABLE或Context.MODE_WORLD_WRITEABLE，會觸發SecurityException。

官方文檔：
Starting from N(N is for Nougat), attempting to use this mode will throw a SecurityException.
7.0後不能這樣用了。

解決辦法就是:

1、Use more formal mechanism for interactions such as ContentProvider, BroadcastReceiver, and Service.

2、MODE_WORLD_READABLE 模式換成 MODE_PRIVATE

3、try catch
