To make a good Android application, it is essential to use the network communication technology, it is difficult to imagine a software without network interaction can eventually develop much success. So let's take a look at how web interactions are implemented in general Android apps, and here's an example of a Boook object: As shown above, first on the phone to generate a book object, which contains the

purpose of serialization for # # #:-Persistence of custom objects in some form of storage;-Transfer objects from one place to another.-Make the program more maintainable.How to serializeTwo ways are described below: Implement the Serializable interface (which is supported by the javase itself)-This kind of serialization is very simple, only need to implement a serializable interface can be implemented, specific reference code: Person Class

Use Intent to transfer Java objects between activities in Android projects -- Implement Parcelable InterfaceUsing Intent to implement Java object transfer between activities in Android projects, there are two ways: one is the passed object implements the Serializable interface; the other is the passed object implements

This is an android app that I used to query the shortest route of Guangzhou Metro. The shortest route transfer query and optimized query results are achieved.There are three difficulties: first, the data structure of the figure is used to build the entire subway station point chart; second, the shortest path algorithm; and third, the optimization of the query res

recycler is not reliable,Especially on mobile phones, it is more unreliable. Therefore, unless we want to make our program worse and worse, we should try to stay away from static.Note: static Bitmap, Drawable, and other variables are often used. It may throw a very famous exception in the Android system (In the past, budget had never been able to remember what it meant. Since this exception was often throw
