Overview Remote Image Retrieval is a commonly used function for client-server applications. image resources consume a large amount of traffic, it will cause a user to crash, and the mobile phone traffic will be used up without knowing it. If the user finds that your application has consumed the mobile phone traffic, you can imagine what fate your application will face.Another problem is the loading speed. If the image loading speed in the application

Remote Service calling is not implemented using AIDL in Android.
Advantages: The DESCRIPTOR on the Client and Server can be customized without the package name restriction.
In essence, it is implemented by using Java layer interfaces such as Binder and IInterface provided by the underlying Binder Mechanism.

Recently, because you want to debug your code on another Android device, check its log on your native PC. Two machines away from the relatively far, can not be directly connected with the USB, so find a lot of information on the Internet, the most find using the ADB Connect method to solve the problem. The resolution process is as follows:1, verify that the native PC does not have any ADB device connections
Significance:
Because each application process has its own independent process space, on the Android platform, a process usually does not access the memory space of another process, and we often need to boast process passing obje

requests (query (), insert (), delete (), update () and the GetType () method) will be called from the thread pool of the process where the content provider resides, rather than from the UI thread of the process. Because these methods may be called from any number of threads at the same time, they must also be implemented as thread-safe methods.Inter-process com
support a process that is often displayed in the interface.
Threads: Even if a different process is assigned to a component, it is sometimes necessary to redistribute the thread. For example, the user interface needs to respond quickly to the user, so some time-consuming operations, such as network connections, downloads, or very intensive server-time operations, should be placed on other threads.

the average developer, So the compiler helped us create a tool that encapsulates interprocess communication, this is the Proxy, which encapsulates the underlying process communication mechanism and exposes only the interface methods, and the client only needs to call the two methods to implement interprocess communication (in fact, the remote invocation of the method) without needing to know the details.
you can expose the AIDL interface (MyBinder) to the client through RemoteService ). Now, if the client (such as an Activity) calls bindService () to connect to this server (RemoteService), The onServiceConnected () callback function of the client will obtain the onBind () from the server (RemoteService () the returned MyBinder object.
Here we will summarize the writing process of the server:
