首先介紹TOKEN 緩存問題

寫個工具類 里面放入

/**?獲取緩存的token*/public?static?String?getCachedToken(Context?context){return?context.getSharedPreferences(APP_ID,?context.MODE_PRIVATE).getString(KEY_TOKEN,?null);}/**?緩存token*/public?static?void?cacheToken(Context?context,?String?token){Editor?e?=?context.getSharedPreferences(APP_ID,?context.MODE_PRIVATE).edit();e.putString(KEY_TOKEN,?token);e.commit();}

ANDROID API 說明：

Interface for accessing and modifying preference data returned by?getSharedPreferences(String, int). For any particular set of preferences, there is a single instance of this class that all clients share. Modifications to the preferences must go through an?SharedPreferences.Editor?object to ensure the preference values remain in a consistent state and control when they are committed to storage. Objects that are returned from the various?get?methods must be treated as immutable by the application.

簡要說明： 修改完數據，一定要提交，數據的有多重保存方式

• MODE_PRIVATE

• MODE_WORLD_READABLE

• MODE_WORLD_WRITEABLE

• MODE_MULTI_PROCESS
