Android Studio Simple Introduction and Usage issues SummaryThis development tool was introduced by Google at the 2013 I/O developer conference. It has now been updated to version 0.5.8.Many of GitHub's projects are now developed using Android Studio, so if you still use eclipse, you need to split the entire project,And then in the project include dependent packages, is very troublesome, and sometimes get a
developers complete code and perform analysis before delivery. Android APIs now mark more metadata and usually return NULL pointers. If you forget to catch these exceptions, Android Studio uses the metadata to identify these potential bugs. I wrote some code that looks neat, but Android Studio quickly found hundreds of methods to make the code run more neatly and faster. The IntelliJ team spent a long time

1. XML Format specification:① must have a root element② cannot have spaces, cannot be in numbers or. Start, case sensitive③ non-overlapping nesting④ Attribute double quotation marks (the browser is automatically corrected into double quotes)⑤ Special symbols to use entities⑥ annotations are the same as HTMLAlthough complex data can be described and transmitted, its resolution is too complex and large, so implementation is rarely used. Cases:

1. Insert Node
To insert a node into a node:
Copy Code code as follows:
XmlDocument xmldoc=new XmlDocument ();
Xmldoc.load ("Bookstore.xml");
XmlNode Root=xmldoc.selectsinglenode ("bookstore")/Find
XmlElement xe1=xmldoc.createelement ("book");//Create a node
Xe1. SetAttribute ("Genre", "Li Zhanhong");/set the node genre property

1. Create a new test project and observe the correctness of the parsing files referenced by System. Xml and Mono. Xml, and
installation path, and then continue:
After the software is installed, the Android SDK will automatically appear in the installation directory:
3. Start running the software:
Note: After JDK is installed and environment variables are correctly configured, the JDK is automatically loaded once Android Studio is run (the premise is that the environment variables are correctly configured ), the Android SDK is also available. Run the software now.
