Data transfer

Conversion between object and byte stream

Why do you want to go? Persistence (forced to say, JVM non-operational), he processes (forced argument, other machine JVM, different JVM)

Parcelable and Serializable

Original intention:

Parcelable:serializable is inefficient and designed to transmit data efficiently between different components within a program and between different Android programs (AIDL).

These data exist only in memory, Parcelable is the carrier of messages that are communicated through IBinder.

Serializable: Save the properties of an object to a local file, database, network stream, RMI to facilitate data transfer, of course, this transfer can be within the program or can be between two programs.

One with memory, one with IO.

UI

Measure-layout-draw reduce the number of child controls

Viewpaper the number of simultaneous cached page numbers is less than 3. and buy a page to load the data or network when it is displayed, to avoid preloading

Picture decode into bitmap memory is multiplied, reducing size is the fundamental factor, allowing the server to provide different convenience rate pictures are good solutions

Thread pool

Adjust control network request frequency on business
