The example in this article describes the approach of Android programming to implement Aidl (cross process communication). Share to everyone for your reference, specific as follows: I. Overview: Cross-process communication (AIDL), which mainly implements data sharing between processes (applications). Two. Implementation process: 1. Server-side implementation: (1) directory structure, as shown below: (2) Implement *.aidl file: A. IAIDLSERVICE.AIDL implementation: Package com.focu

Activity passes values between intent, supports basic data types and string objects and their array objects byte, byte[], Char, char[], Boolean, boolean[], short, short[], int, int [], Long, long[], float, float[], double, double[], String, string[], and adopt the implementation of Serializable, The Parcelable interface's class object passes data in two ways: one is bundle.putserializable (Key,object) and the other is Bundle.putparcelable (Key, Object

When data is passed between activity, it is convenient to encapsulate a lot of data into objects and then pass the entire object over. There are 2 of cases in the object,One is to implement the Parcelable interfaceOne is to implement the Serializable interfaceUse the Bundle.putserializable (key, object) origin parameter or use Intent.putextra (Key object) to pass the parameter.But when used, an exception occurs1.java.io.notserializableexception except

Android Studio is a common plugin that greatly simplifies development and enhances development efficiency.Do not know the installation studio plug-in, read the previous article:1, Butterknife ZeleznyButterknife annotation generator, very easy to use, use Butterknife blessed!2, SelectorchapekDesigners to provide us with all kinds of resources, each button to write a selector is not very troublesome? So this plug-in to solve this problem, you only need to do is to tell the designers to follow the

and paint that Android123 will cover in the future, In the canvas we can implement picture paths, graphs, areas, lines. Paint as a way of painting objects can be set color, size, and even the type of font and so on.}Of course, there is the processing window restore state problem (generally used for screen switching), in addition to the activity can be called outside, in the development of the game we try to use similar in viewView Plaincopy to Clipboardprint@OverrideProtected

the state of your Preference class, you must implement the lifecycle callback methods and onSaveInstanceState() .The state of your was defined by a Preference object that implements the Parcelable interface. The Android framework provides such a object for you as a starting point to define your state object:the Preference.BaseSavedState class.To define how your Preference class saves it state, you should extend the Preference.BaseSavedState class

To serialize an object by implementing the Parcelable interface:1, realize parcelable interface.2, and implement the public Parcelable interfacevoid Writetoparcel (Parcel dest, int flags) method.3. A custom type must contain a static member named Creator, which requires the implementation of the Parcelable.creator interface and its methods. publiccla

-side program:(1) First Write your class (Book.java) file, this class must implement the Parcelable interface to serialize.(2) write the Aidl file (book.aidl) with the same name as the class(3) Writing the interface file (IBOOKMANAGER.AIDL), which is the interface of the client when requested(4) Implement service (Bookmanagerservice) on the server, which serves the client in real-time (mainly implements stub class)Next, let's look at the steps the cli
