Original:. Net moving Android 4.4 daily notes (2)--helloworld Starter Program

I don't know why people like to use HelloWorld as their first program to get started, why not hello * * other things or hi.

First, open ADT's Eclipse development tool to create a new Android project

New----> Android application Project

Minimum Required SDK This is the lowest Android version to run Hello World

Target SDK is now the targeted version

Compile with is a compiled version

Theme is the subject

In general, I'm a beginner. The next step is okay, and I don't know what it is.

Successfully created

Specifically see the red box in the SRC is the source code, equal to our. NET under the Cs,layout is the layout file, such as HTML page

I do not know why the book created in the layout only activity_main, it may be because of the new ADT reason, check to know Fragment_main one is compatible with the tablet.

This does not matter, now the mobile phone is as big as the tablet.

Second, start the simulator

　　

Third, the debug program (to wait for the simulator to start successfully to debug, or seemingly no effect)

Right-click Project Run as or Debug as to Android application see the effect

The line almost started, know how to run, the next is to learn what buttons, controls, databases, UI and so on.
