很多SharedPreferences錯誤

當我以嚴格模式啓動我的應用程序時，我遇到了很多相同的錯誤。仿真器顯示我的「存儲空間捉迷藏了」很多SharedPreferences錯誤

錯誤：

我共享偏好類是：

public class SharedHelper { 

public static boolean setProductFilePath(String path) { 
    return getAppPreference().edit() 
      .putString(Constants.PATH_NAME, path) 
      .commit(); 
} 

public static String getProductFilePath() { 
    return getAppPreference().getString(Constants.PATH_NAME, ""); 
} 

public static boolean setClientFilePath(String path) { 
    return getAppPreference().edit() 
      .putString(Constants.PATH_CLIENT_FILE, path) 
      .commit(); 
} 

public static String getClientFilePath() { 
    return getAppPreference().getString(Constants.PATH_CLIENT_FILE, ""); 
} 

public static boolean setEmail(String path) { 
    return getAppPreference().edit() 
      .putString(Constants.EMAIL, path) 
      .commit(); 
} 

public static String getEmail() { 
    return getAppPreference().getString(Constants.EMAIL, ""); 
} 

public static boolean setQuantityColumns(String path) { 
    return getAppPreference().edit() 
      .putString(Constants.QUANTITY_OF_COLUMNS, path) 
      .commit(); 
} 

public static String getQuantityColumns() { 
    return getAppPreference().getString(Constants.QUANTITY_OF_COLUMNS, ""); 
} 

public static int getListState() { 
    return getAppPreference().getInt(Constants.LIST_STATE, 0); 
} 

public static boolean setListState(int listState) { 
    return getAppPreference().edit() 
      .putInt(Constants.LIST_STATE, listState) 
      .commit(); 
} 


public static SharedPreferences getAppPreference() { 
    return App.newInstance().getSharedPreferences(Constants.APP_PREFERENCE_KEY, Context.MODE_PRIVATE); 
}

爲什麼我有太多的錯誤？（約20個相同的錯誤）

你把所需的權限？在我看來，你忘了補充一些。 –

是的，我有一切必要的權限： – Delphian

您的設備中沒有足夠的空間來寫入文件。檢查以下線程並選擇可能適合您情況的解決方案 –

使用助手類並避免複雜性。這是我寫的 - Android-SharedPreferences-Helper

Simplifies usage of the default Android SharedPreferences Class. The developer can do in a few lines of code which otherwise would have required several. Simple to understand as compared to the default class and easy to use.
