Storing Large ArrayLists To SQLite

I im developing a application in which I continuously download large amount of data. The data in json format and I use Gson to deserialize it. By now Im storing this in a SQLite db

Solution 1:

Yes, serialization is a better solution in your case and it works in Android. The following example is taken from http://www.jondev.net/articles/Android_Serialization_Example_%28Java%29

serialization method:

  public static byte[] serializeObject(Object o) { 
    ByteArrayOutputStream bos = new ByteArrayOutputStream(); 

    try { 
      ObjectOutput out = new ObjectOutputStream(bos); 
      out.writeObject(o); 
      out.close(); 

      // Get the bytes of the serialized object 
      byte[] buf = bos.toByteArray(); 

      return buf; 
    } catch(IOException ioe) { 
      Log.e("serializeObject", "error", ioe); 

      return null;
    } 

deserialization method:

  public static Object deserializeObject(byte[] b) { 
    try { 
      ObjectInputStream in = new ObjectInputStream(new ByteArrayInputStream(b)); 
      Object object = in.readObject(); 
      in.close(); 

      return object; 
    } catch(ClassNotFoundException cnfe) { 
      Log.e("deserializeObject", "class not found error", cnfe); 

      return null; 
    } catch(IOException ioe) { 
      Log.e("deserializeObject", "io error", ioe); 

      return null;
  }
