Module
IntelliJ IDEA distinguishes between the following types of Android modules:
| Module Type | Description |
|---|---|
| Gradle Module | Create Android applications or libraries that are compiled and built with the Gradle build tool. |
| Application Module | Module that is ready for developing an Android application. (IntelliJ IDEA will create an application package and set up the Android-specific module structure.) |
| Empty Module | Contains two empty folders: gen and src. |
| Library Module | For holding shared Android source code and resources (Other Android application projects can reference a library project and include its compiled sources in their .apk files at build time. The Android facet of the module will have the Library project check box automatically selected) |
| Test Module | For creating and running Android unit tests. |
Target device
Target Device in the Project wizard:
| List | Description |
|---|---|
| Do not create run configuration | If you do not want to set the Run/Debug configuration at this point. You will be prompted to configure it when you first launch a run or a debug session. |
| Show device chooser dialog | The Choose Device Dialog will be displayed each time you start a run or a debug session. |
| USB device | IntelliJ IDEA will automatically detect a plugged-in USB device upon the application start. |
| Emulator | The preferred Android Virtual Device will be launched when you start a run or a debug session. |
