| <p>If you're unfamiliar with the IntelliJ IDEA interface, you might be wondering |
| how to accomplish some common tasks in Android Studio. This page provides some tips |
| to help you get going.</p> |
| |
| <p>For complete user documentation for the IntelliJ IDEA interface |
| (upon which Android Studio is based), refer to the |
| <a href="http://www.jetbrains.com/idea/index.html">IntelliJ IDEA documentation</a>.</p> |

| |
| <h2 id="Project">Project Structure</h2> |
| |
| <p>When you create a new project in Android Studio (or |
| <a href="{@docRoot}sdk/installing/migrate.html">migrate a project from Eclipse</a>), |
| you'll notice that the project structure appears differently than you may be used to. |
| As shown in figure 1, almost all your project files are now inside the {@code src/} directory, |
| including resources and the manifest file.</p> |
| |
| <p>The new project structure is due to the switch to a Gradle-based build system. This structure |
| provides more flexibility to the build process and will allow multiple build variants (a feature not |
| yet fully implemented). Everything still behaves as you expect, but some of the files have moved |
| around. For the most part, you should need to modify only the files under the {@code src/} |
| directory. More information about the Gradle project structure is available in the |
| <a href="http://tools.android.com/tech-docs/new-build-system/user-guide">Gradle |
| Plugin User Guide</a>.</p> |

| |
| <h2 id="Basics">Basic Operations</h2> |
| |
| <p>The following topics describe how to perform |
| some basic development tasks with Android Studio.</p> |
| |
| <p class="note"><strong>Note:</strong> This section lists Android Studio keyboard shortcuts |
| for the default keymap. To change the default keymap on Windows and Linux, go to |
| <strong>File</strong> > <strong>Settings</strong> > <strong>Keymap</strong>. To change |
| the default keymap on Mac OS X, go to <strong>Android Studio</strong> > |
| <strong>Preferences</strong> > <strong>Keymap</strong>.</p> |
| |
| <h3>Creating virtual devices</h3> |
| |
| <p>All the capabilities of the <a href="{@docRoot}tools/devices/managing-avds.html">Android |
| Virtual Device Manager</a> are accessible directly from |
| the Android Studio interface. Click the <strong>Android Virtual Device Manager</strong> |
| <img src="{@docRoot}images/tools/avd-manager-studio.png" |
| style="vertical-align:bottom;margin:0;height:19px" /> in the toolbar to open it and create |
| new virtual devices for running your app in the emulator.</p> |
| |
| |
| <h3>Installing SDK updates</h3> |
| |
| <p>The <a href="{@docRoot}tools/help/sdk-manager.html">SDK Manager</a> |
| is also accessible to download new Android tools, platforms, and libraries |
| for your app. Click the <strong>SDK Manager</strong> |
| <img src="{@docRoot}images/tools/sdk-manager-studio.png" |
| style="vertical-align:bottom;margin:0;height:19px" /> in the toolbar to open it and check |
| for updates.</p> |
| |
| |
| <h3>Creating new files</h3> |
| |
| <p>You can quickly add new code and resource files by clicking the appropriate directory in the |
| <strong>Project</strong> pane and pressing ALT + INSERT on Windows and Linux or COMMAND + N on Mac. |
| Based on the type of directory selected, Android Studio offers to create the appropriate file |
| type.</p> |
| |
| <p>For example, if you select a layout directory, press ALT + INSERT on Windows, and select |
| <strong>Layout resource file</strong>, a dialog opens so you can name the file (you can exclude |
| the {@code .xml} suffix) and choose a root view element. The editor then switches to the layout |
| design editor so you can begin designing your layout.</p> |
| |
| |
| <h3>Creating layouts</h3> |
| |
| <p>Android Studio offers an advanced layout editor that allows you to drag-and-drop widgets |
| into your layout and preview your layout while editing the XML.</p> |
| |
| <p>While editing in the <strong>Text</strong> view, you can preview the layout on devices by opening |
| the <strong>Preview</strong> pane available on the right side of the window. Within the |
| Preview pane, you can modify the preview by changing various options at the top of the pane, including |
| the preview device, layout theme, platform version and more. To preview the layout on multiple |
| devices simultaneously, select <strong>Preview All Screen Sizes</strong> from the device drop-down. |
| </p> |
| |
| <p>You can switch to the graphical editor by clicking <strong>Design</strong> at the |
| bottom of the window. While editing in the Design view, you can show and hide the |
| widgets available to drag-and-drop by clicking <strong>Palette</strong> on the |
| left side of the window. Clicking <strong>Designer</strong> on the right side of the window reveals |
| a panel with a layout hierarchy and a list of properties for each view in the layout.</p> |
| |
| |
| <h3>Debugging</h3> |
| |
| <p>When you build and run your app with Android Studio, you can view adb and device log messages |
| (logcat) in the DDMS pane by clicking <strong>Android</strong> at the bottom of the window.</p> |
| |
| <p>If you want to debug your app with the <a |
| href="{@docRoot}tools/help/monitor.html">Android Debug Monitor</a>, you can launch it by |
| clicking <strong>Monitor</strong> <img src="{@docRoot}images/tools/monitor-studio.png" |
| style="vertical-align:bottom;margin:0;height:19px" /> in the toolbar. The Debug Monitor is where |
| you can find the complete set of <a href="{@docRoot}tools/debugging/ddms.html">DDMS</a> |
| tools for profiling your app, controlling device |
| behaviors, and more. It also includes the Hierarchy Viewer tools to help |
| <a href="{@docRoot}tools/debugging/debugging-ui.html">optimize your layouts</a>.</p> |

| <p>The following tables list keyboard shortcuts for common operations.</p> |
