Section 2. The opened files can be activated from the tabs located here for viewing in the middle pane.


Section 3. This is the middle pane. Contents of the active files can be viewed and changed from here.
file called “MainActivity.java” is the active tab in Section 2 therefore the middle pane in Section 3 shows the contents of this “MainActivity.java” file.


Section 4. This section is also controlled via tabs. The developer can switch project files, structures, captures and favourites for viewing in the left pane.


Section 5. The current or previous compilation, building or debugging processes are shown here. For the snapshot of Figure 3.6, it is indicated that the “Gradle build finished in 14 seconds”. Gradle is the build system of Android Studio. Therefore, the message says that the building engine completed its previous task in 14 seconds.


Section 6. This is the Run button of Android Studio. When we set up the user interface and write the Java code of a project, we click this button to make the Android Studio build the project (which means creating the executable file from project files) and then we can run it on an emulator or on a real device.
