Viele SharedPreferences Fehler

Question

Wenn ich meine App im Strict Mode starte, habe ich viele der gleichen Fehler. Emulator zeigt mir "Speicherplatz runnning out"

Fehler:

E/StrictMode: A resource was acquired at attached stack trace but never released. See java.io.Closeable for information on avoiding resource leaks.

Meine Gemeinsame Vorlieben Klasse ist:

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); 
} 

Warum ich zu viele Fehler haben? (ungefähr 20 gleiche Fehler)

Answer 1

Verwenden Sie eine Hilfsklasse und vermeiden Sie die Komplexität. Hier ist eine, die ich schrieb - 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.
