Build First Application Using Android Studio

Step 2: Click "Next" to create a custom launcher icon If you have not selected this option in the previous screen then you are not able to define a custom launcher icon and text in this wizard. You can still define it manually after project creation. You can also select "custom image" from Clipart. You can also select the option "Text" to set the launcher text icon as in the following: Step 3: Click "Next" to Define Activity This screen will let you select a default sample activity, like Blank Activity, Full-Screen Activity, and Master/Detail Activity etcetera. If you have not selected this option on the main screen then you are not able to select this default activity. You need to define a new activity in your package yourself. Step 4: Click "Next" to Create the Main Activity You are now at the last step of project creation. Give an Activity name in the field, then give a layout name and if you like, select navigation like "Fixed Tab + Swipe" etcetera then select an option from the drop-down list. Now, click on the "Finish" button to complete this project wizard. This will next configure your new project settings. If "Gradle" is not installed in your disk then this will download all the dependencies before this. So wait until the setup is finished. If the package can't be downloaded then go to the "Configuration" screen, and find "HTTP Proxy" and ensure that your internet connection is okay The next screen, after successful configuration, will look like this: Here, you will see that, our "MainActivity" resides in "src/main/java/com.<package>/". You can also see our resources structure. The layout file that we defined in "wizard" is here in the "src/main/res/layout" directory. When I open this layout file, the following screen will open. I have made some changes to the layout file.

When you go to the "text view" of layout, you are able to view the changes you are making in the text file, and the output will immediately be reflected in your design. This Android Studio has one good facility called "Preview all screen sizes", that allows the user to see the output of the current layout file with all the supported devices with simulated output. You are almost done with everything. Now, as you code in Eclipse, do the same here. Run your project by selecting an AVD or a real device. There are so many features in this IDE, we will explore in my next article.
