例外情况仅发生在Android 7.0 Nougat(模拟器)设备中.

java.lang.SecurityException: MODE_WORLD_READABLE no longer supported

我的代码：

public void SessionMaintainence(Context context) {

this.context = context;

preferences = context.getSharedPreferences(PREF_NAME, Context.MODE_WORLD_READABLE);

editor = preferences.edit();

editor.commit();

}

logcat的：
