The most important component services and activities of Android are the communication problems between them. Of course, today we will not study the underlying implementation issues. I will study how to use the upper-layer applications. First, the activity calls the service This is relatively basic, and there are two common methods; First, using intent, this is relatively simple. You can specify the package name and class name to call it. The intent. s

As an android client of the website, the user installs it on his mobile phone. What if I release a new version? You must have the version update function. It is best to perform automatic version check. However, if you start a program each time, you need to check for a round first, which is a waste. After all, version update is a small probability. Maybe you can j

I. Client element client element layer ArcGIS Android provides a client element layer graphicslayer. With ArcGIS's previous web development experience, we can know that this layer is used to draw client elements. Let's try to add another graphicslayer in mapview: "1.0"Encoding ="UTF-8"?> Http://schemas.android.com/apk/res/android"

Asynctask is more lightweight than handler, and is suitable for simple asynchronous processing without the need for threading and handter. Asynctask is an abstract class. Asynctask defines three types of generic type params,progress and result:The params input parameter that initiates the task execution, such as t

Makes it possible for us to access the UI in a child thread to make the program run? Next we'll use an example to confirm it.To create a new project, the Activity_main.xml layout looks like this:XML version= "1.0" en
