Before making the first program you have to create a android virtual device on your computer. So this can be done by the following steps
STEP-1. Open your eclipse(IDE) and select icon “Android Virtual Device Manager”. Android Virtual Device Manager is the 4th or 5th icon in your eclipse tool bar.
STEP-2. Android Virtual Device Manager opens . here you can give name to your device(name of my device is abhi) ,target select the version you want to have on your virtual phone( i have selected Android 3.0). then press Create AVD.
now we make android program and run it.!
STEP-3. File>new>other>android>android project. now click “next” , now give name to your project then click “next”. Now select target name( i have selected Android 3.0). Then click “next”, now give package name(i have given android.android1) then click finish.
Now files we have to work with are ” AndroidManifest.xml , src/android/android1/AndroiddemoActivity.java , res/layout/main.xml , res/values/string.xml “.
now to run the program right click on the android root folder click on run and run as android application.
