Above a blog, introduced the advantages of Studio and 1.0 RC installation and hands-on experience, did not expect Google's update speed so fast, has been out of RC 2 version, mainly to fix some bugs. So today we will take you to preview the next Stduio interface and basic functions.

Project structure

When we create a new project, the directory structure defaults to this

You can see that the directory structure of Eclipse is very different, studio can only have one project, and Eclipse can have a lot of projects at the same time, if you look not accustomed to click on the upper left corner to switch

Switch to the directory structure in project mode I'm more comfortable with this format myself.

The differences with eclipse are as follows:

• 1. There is a concept of project and module in studio, which says that a window in studio can have only one project, project, which represents a workspace, but a project can contain multiple module For example, the Android library, Java Library and so on, which are referenced by your project, can be regarded as a module;

• 2, the above directory will be Java code and resource files (Pictures, layout files, etc.) all boil down to SRC, in the SRC directory has a main group, while dividing the Java and res two folders, Java folder is equivalent to the SRC folder under Eclipse, The RES directory structure is the same.

Preference settings

After entering you may find that the font size or style does not conform to your habits, such as I think the code is too small to look hurt, darcular theme default font is 12, I personally more accustomed to 14 font size. Okay, to Preferences (set) page search font find the font option under colors&fonts , we can see the default font size is 12, But cannot modify, need to save before you can modify, click Save as to enter a name, such as mydarcular, then you can modify the font size and font style.

Click OK to go back to the page to find that the font is larger, but studio default some font size, such as the sidebar does not change, looks very uncoordinated, such as

Obsessive Compulsive Disorder You certainly unbearable, OK, here also can set, to Preferences , appearance modify on OK, here also not only can change font size, also can choose different font, click OK, This page font is totally in your appetite.

Adjust and then look at the effect

It is recommended that you update the ToolsandExtras in the SDK manager to the latest before creating the simulator.

Select a system version here, take 5.0 for example, then next

Since your screen size is different, it is recommended that you select Auto in the scale column, then click Finish to see that we have created the simulator for good one 5.0.

This time we run again, choose the simulator to start looking at the final effect (the simulator starts very slowly, everybody waits patiently)
